Abstract

PROBLEM TO BE SOLVED: When searching for literature information, it takes too much time to search a large number of unrelated materials and select from them because the scope of the search is too wide in the IPC field search and keyword search etc. There was a problem that it was difficult, or there was a problem that important data was leaked if the search range was narrowed down.
The present invention relates to a specific individual selecting means for selecting a specific individual who is an author or an inventor from literature information extracted from a server based on a generated search formula, and a specific individual selected by the specific individual selecting means. It is possible to search for the results of individual activities and prevent omissions through simple surveys. In addition, not only engineers but also literary researchers can grasp the progress and trends of research that they want to investigate.

Description

  The present invention relates to a search system technique for extracting necessary information from a large amount of document information.

  Many companies compete for development each year regardless of domestic and foreign countries, such as home appliances such as washing machines, air conditioners, refrigerators, digital cameras, personal computers, etc., and technologies that accompany this development. Many patent applications related to development have been published. In addition, there are many technical materials other than patent applications such as electronic parts technology, nanotech technology, presentation of academic research on biological research such as genes and brain science in the pharmaceutical industry, publication of literature, etc. Furthermore, the range of studies that have been considered to be literary is not distinguishable from science, and related literature covers too many fields. For example, in linguistics, physics, medicine, psychology, philosophy, and so on, it is very difficult to conduct information research outside of specialized fields, not only when conducting research by yourself, but also by requesting specialists. Further, such information is not limited to literatures and patent gazettes, but is published on the Internet.

  In the case of a patent application for such a large amount of literature information, the patent office provides a searchable system, and many organizations and companies also provide a system that can be generally used. Search systems include, for example, applicant search, document number search, IPC code (international patent classification) search, patent claims and full-text keyword search, and in recent years, concept searches that search based on text similarity have also appeared. ing. There are also searches for the inventor or a combination of these searches. On the other hand, a similar system is also provided for various presentation contents and documents, and individuals and the like can investigate from a personal computer. In the Internet world, a system that can identify where and what materials are available by keyword search is standard.

  As a conventional technique for extracting specific information from such a large amount of document information, for example, a map generation method for collecting patent information from a large number of patent information by IPC classification (see Patent Document 1), applicant and field Supporting the creation of a patent portfolio from classification of each term (see Patent Document 2), and a search system for patents and documents that allows users to select and reselect words from the search results (patents) Reference 3), field items are set in the database, the field items are weighted to perform a search efficiently (see Patent Document 4), fixed sentences such as sentences explaining software functions, etc. Are searched by using the similarity of sentences and the similarity of terms by disassembling a plurality of constituent terms and using them as reference terms (see Patent Document 5), etc. It is known.

JP 2002-175314 A (FIGS. 1 and 2) Japanese Patent Laying-Open No. 2003-76796 (FIG. 1, claim 1) JP 2002-351896 (Claim 1, 0064 column) JP 2001-184365 A (FIG. 4, column 0085) JP-A-6-124368 (FIGS. 5 and 7)

  As a problem to be solved, the conventional techniques for investigating information mainly consist of investigations corresponding to the purpose such as investigation of known materials. For example, in the search for patent applications, the main purpose is to examine the patent as the right holder, when it became publicly known, the content of the rights, etc., and search activities to avoid or crush specific patents The purpose of the research was to search for documents similar to the texts and terms of the patent from among the known documents prior to the filing date of the patent. However, even if we try to search the literature on the contents of the rights and the full text of the patent, the search by the IPC field or the keyword search etc. is so wide that the search scope is too wide to pick up a lot of irrelevant materials and select from them There was a problem that it took too much time and was difficult, or there was a problem that important data was leaked if the search range was narrowed down. For example, when trying to investigate documents that use carbon dioxide as a refrigerant, there are too many irrelevant documents in the IPC field survey, while in the keyword search, carbon dioxide and symbols other than carbon dioxide are listed. There was a problem related to research techniques, such as differences in contents and symbols, numbers and alphabets, for example, if all combinations of uppercase and lowercase letters are not listed, documents that do not contain them are not included.

  Therefore, in patent search and literature search, it is common to request search skills and search specialists and search companies, and search companies also search for specific technical contents and fields for efficiency. Expertise and the creation of a specialized database are underway, and it will deviate from the intended purpose and efficiency improvement, for example, because it is out of the conventional purpose, or it is not noticed or neglected for the survey activity in the direction of deviating There was a problem that research activities would be eliminated. Further, there is a problem that even if the creation of a patent map is requested, the technical contents such as the number of applications per year and the number of applicants are limited to abstract and general reports and do not include specific technical contents required by the user.

  Also, even if a specific right is invalidated or a specific technology is thoroughly investigated, there is always a question about whether or not there is a complete omission when narrowing down and narrowing down the scope of the survey. There was a problem that it was expensive and time consuming to continue investigating forever without being convinced. On the other hand, there is a problem for research specialists that, other than their own specialties, for example, investigators specializing in engineering technology are not confident in linguistics, psychology, medicine, etc., and it takes time and effort. Also, the person who requested the survey had a problem that taking such a survey would not only be complete, but it would not only cause dissatisfaction but also increase the risk. Furthermore, there was a problem that for the technical theme to be investigated, it was not possible to grasp the movement of the world's technology and the like simply by obtaining a list of documents disclosing specific technical contents.

  The present invention has been made to solve the above-described problems. When searching for literature information, an apparatus capable of performing a reliable and short-term survey regardless of the field of science or culture. The purpose is to provide a method. It is another object of the present invention to provide an information investigation apparatus and method, and a recording medium that can surely grasp the trend and direction of the technology flow and record and express it in an easily understandable form. It is an object of the present invention to provide a reliable and practical method for conducting a thorough investigation.

  The information research apparatus of the present invention includes an input means for inputting a specific item for generating a search expression, an extraction result recording means for extracting document information from a server based on the generated search expression, and the extracted and recorded document information Specific personal selection means for selecting a specific individual who is the author or the inventor from, and output summarization means for collectively outputting the contents of the document information created by the specific individual selected by the specific personal selection means in time series It is a thing.

  The information survey method of the present invention includes a step of extracting document information based on a search formula generated by a specific item related to information to be investigated, a step of selecting a specific individual who is an author or an inventor from the extracted document information, And a step of collecting the reference information created by the selected specific person in time series, and the specific individual is a team composed of a plurality of persons or a plurality of persons.

  The information search method of the present invention includes a step of extracting reference information based on a search formula generated by a specific item of an upper layer first, enabling a plurality of layers to input a specific item for generating a search formula of information to be searched. Select a plurality of specific individuals who are authors or inventors from the extracted document information, collect the document information created by the selected specific individuals in time series, and then generate the specific items in the lower layers And a step of extracting literature information created by a specific person excluding the specific person based on the retrieved search formula.

  The recording medium of the present invention is a recording medium that collectively records reference information created by a plurality of specific individuals selected from reference information extracted based on a search formula including a problem such as technology, and the result of the summarization Is displayed in a plurality of axes, and one axis is a time series based on the submission date or publication date of the document or the filing date of the patent application.

  The present invention makes it possible for anyone to easily search from a wide range of themes to a specific desired theme and to easily narrow down. In addition, the present invention provides an apparatus and a method capable of creating a patent map that is easy to understand the flow of analysis and technology development for a specific technology theme. In addition, the present invention can efficiently perform a thorough investigation to obtain a target document or technical theme. In addition, the present invention can perform a continuous investigation at a low cost, and can make the record easier to see.

Embodiment 1 FIG.
FIG. 1 is a system explanatory diagram for explaining a configuration using, for example, a personal computer, which is an information research apparatus according to Embodiment 1 of the present invention. In FIG. 1, an information survey apparatus 1 is connected to a network 3 such as a LAN or the Internet, and accesses a document information server 21, a patent information server 22, or an information database 23 connected to the network 3 to retrieve document information. Or it is comprised so that the processed information may be sent out to the information investigation device 2 or the database 23. The information investigation device 1 is a control device 4 that searches information, creates a map, etc., for example, a computing unit or storage unit of a personal computer, an input means 5 for inputting data necessary for the search, a search expression or search result to be searched The display means 6 can display the extracted list and the like, and the storage medium 7 stores the input / output results.

  The control device 4 includes a communication means 9 that is an interface for exchanging communications with the outside such as the network 3, an input / output device 8 that performs input / output processing, and the contents to be searched that are input from the input means 5, etc. There is a search expression generation means 10 that generates a search expression received via 8 and connects to an external server for communication. The literature information extracted from the information servers 21 and 22 based on the search formula and the information gathered in the other information research apparatus 2 and the information server database 23 are temporarily stored in the extraction result recording means 12. This extraction result is classified by the specific person selection means 11 for each person such as an author or an inventor, and the output summarization means 13 is closest to the date and time when the publication contents such as the document submission date and the application date were created or summarized. A list that summarizes the contents of the map and the summary of the output results together with the document contents and the bibliographic items in order of date. The collected results and information sent from other information investigation devices are recorded in the recording means 15 and can be transmitted to other information investigation devices 2 and the database 23 via the communication means 9, for example. . The output result that summarizes the document information is sent from the input / output device 8 to the external display means 6 or the recording medium 7 such as a disk via the result display / recording control means 14 for recording or investigation in the next stage. Or, it is used for reviewing and reporting of operators who conduct information surveys.

  One feature of the present invention is to identify the individual who is the author of the document or the inventor of the application, and summarize the contents of the document of the individual in time series based on the date on which the contents can be understood to be completed. Articles such as papers are copyrighted, and the claimed invention has the inventor's invention rights. Like papers, patents, etc., ideas, analysis contents, technical contents, etc. are linked to individuals. Even if the right holder is pursued or the content of the right is grasped, the individual contents as individual activities collect and analyze and examine the individual specific contents confirmed by experiments, simulations, etc. and their progress. The flow cannot be grasped. In order to specify this individual activity, a person name search by inputting the name of a specific person known from the input means 5 may be performed, or a field to be investigated and specific contents to be investigated are designated as specific items. It is better to extract a plurality of names in the order in which the number of documents is large, a specific research institute, company, etc., and select a joint author or joint inventor from the extracted results. If this extracted document information is divided into specific items, for example, those related to a specific technical problem so that the specific technical problem can be understood, documents that are the results of activities of a plurality of specific individuals in various fields It is possible to grasp trends and directions related to specific technical issues in a time-series flow of information.

  Another feature of the present invention is a technique in which an individual is first identified by a primary search and the extraction result is selected for a population that is easy to investigate by limiting the number of individuals to be identified, and it is desired to know the entire bibliographic information of the specific individual. The content is divided and summarized. This allows efficient general surveys first. If it is judged that the results of the primary search are inadequate, this particular individual, except for those who have already been surveyed, is excluded, but the survey of the population focused on it is repeated in multiple stages to improve accuracy, The search is to re-specify individuals through multiple layers of surveys, such as preventing changes from being surveyed and focusing on more precise technical content. This ensures a reliable and reliable investigation. In addition, when themes such as name and technology are entered first, the number of documents for the remaining collaborators other than those who have already been extracted and registered is small, or the number of registered individual searches for technical themes If the display means 6 can read that the number of searches to be excluded has decreased, it may be entered from the input means 5 and registered as other miscellaneous documents as it is, and the process may be terminated. Moreover, the list of output summarization results that have already been registered is read out, the contents are examined, and if the information researcher's aim is included, the end may be input.

  Further, the survey request side and the survey execution side have a meeting, or set from the beginning, and search again. This can be ensured when there are a large number of cases left or when the point you want to investigate is not included, and it can be entered manually, but it can also be done automatically without checking halfway. In this case, the contents of the specified range to be input first are multi-layered. That is, if the specified content of the primary search is higher in the IPC code or a broad word / phrase, the text is input as the next secondary search, and the specific content such as the related word / phrase, action and problem is described. The number of surveys can be controlled by narrowing the survey scope. On the other hand, in the case where the specific content is set as the primary search from the beginning, it is possible to take measures to prevent omission by starting from the investigation to narrow down the noise by using the high-level concept words and related words as secondary search. In this way, it is possible to collect information in a form that is easy to investigate and eliminates the waste of searching for the same specific individual many times by repeatedly narrowing down the survey in the population with limited scope and targets. . In other words, another feature of the present invention is that a person's name is first identified by a literature survey in a specific item, and the literature information of the identified person is collected in a time series and the specific items can be classified. Therefore, since the repeated survey is limited to the literature survey of the remaining people, the survey scope is limited more and more easily.

  The input contents of this hierarchical input method are formed in a form so that they can be easily handled at the time of a survey request. If they are input as they are, they are generated by the search expression generation means 10 and the persons listed by the specific person selection means 11 However, in the next search, when the next individual is specified as it is, the number of registered individuals is excluded, so the number of search targets is narrowed down to secondary and tertiary. In addition, by narrowing down the number of people who check each stage and each level and the number of documents, the survey population for intermediate checks can be limited to a range where the literature information can be read, and this limited population check is repeated almost at the end. A high-reliability and efficient survey that not only enables quick research but also ensures thorough research because it can check the number of documents and the total number of bibliographies and bibliographic items left on the way. Is possible.

  Next, the search procedure described so far in the specific item search flow of FIGS. 2 and 3 will be described in detail. First, a system in which the information investigation device 1 can be searched by START, for example, a personal computer is turned on and connected to the information server via the communication line 3. A specific item is input from the input means 5. An example of this specific item is described in the diagram explaining the form for requesting the survey content in FIG. The survey request form shown in FIG. 4 is an example of a document requested from a sender on the survey request side to a destination on the survey execution side. The specific item entry column 2 for generating the search formula is described. In the column of the object for primary search in these two terms, in order to specify the search target period, for example, the survey period (b) for the last 5 years, the example of the specific range (b), and the technology that is the research theme Issue (c) is described. Depending on the information server to be accessed, it may not be necessary to fill in the period, or it may be the full range of machine search. Or if you want to get the latest technological trends, you can use the last 3 years. Examples of specific range (b) include the designation to be the published patent gazettes of Company A and Company B as in Example 1, search from the name of the individual as in Example 3, or stop this range designation, etc. But it ’s okay. On the other hand, the technical problem is described with a classification code, a keyword, or the like in correspondence with the technical problem as much as possible.

  Furthermore, in the example of the survey request form, the lower layer that is the second or later search that searches multiple layers is a search for the same period as the primary search, related words of the primary search technical problem, sentences for concept search, etc. Is described. Of course, upper and lower classification codes may be brought. In this example 1, the broader concept words, related situation words, and related action property words are described and expanded to the range expanded from the primary search, that is, to the vicinity of the survey range when an individual was specified by the technical problem of the primary search. There is a case where a specific range is described aiming at selecting an individual. Next, Example 2 is an example in which the same category word or subordinate concept word such as the difference in alphanumeric characters described above is described in order to investigate the missing range in the primary technical problem. Example 3 is performed in a case where the aim is off, and is performed again in order to obtain a technical problem from the beginning based on the text by the concept search. Of course, in the case where the specific person extraction is further required in the primary search, the primary search may be repeated any number of times before the secondary search.

  First of all, in FIG. 2 (a), specific items for primary and secondary search, for example, a recent trend survey, a period of about 3 to 5 years in the past, and then the types of documents such as published patents of multiple companies are specified. Furthermore, as a technical subject, ST1 is used to input a carbon dioxide refrigerant, a supercritical refrigerant, or a keyword necessary for another investigation. A search expression is generated by the search expression generation means for the specific item input from the input means 5, and the technical problems in the specified specific range for the last four years, for example, are described from the information server via the communication means 9. Documents are picked up and temporarily stored in the extraction result recording means 12. The number of cases for each person name is extracted from the stored literature information, ST2, the number of person names, that is, ST3 as the first individual person, and the person name in the order of the largest number is specified by the individual person setting means ST4.

  In FIG. 2, next, the joint author / joint inventor described in the literature information of the largest number of persons is identified in order ST5 and ST6. In order to identify a large number of cases, for example, about 20 people or less will be investigated first, but in order to include the joint inventor, the top 10 people in 4 years and the common top people from the top 10 people in the latest year are selected. In this way, a population that can be surveyed almost easily is obtained. That is, the maximum number of people here is about n = 10 to 20 people. It should be noted that the technical problem has been narrowed down from the beginning and that this number has not been reached due to four years, and the secondary search is continued as it is. If the search is broadened by the primary search, the search of the superordinate concept, or the search for a long period of time, only the maximum number of people set in ST4 to ST7 is repeated, and the secondary search is further narrowed down. ST8 where the specific persons extracted here are collected and taken over to ST21 in FIG.

  Next, as a secondary search, the primary search conditions, for example, the period of about 3 to 5 years in the past, the specification of the document type is the same, such as a patent published by multiple companies, etc. Set the hierarchy at K and access the information server by generating a search expression again with limited words, such as ST9, ST10, CO2 which is the same category, and the device name using carbon dioxide refrigerant as a lower concept word ST11 to extract the name and number of people. In this hierarchical extraction configuration, the secondary or lower order may be set in advance, or may be reset after the primary result is displayed and examined. At the time of extraction of the second and lower person names / numbers, a specific person name extracted in a higher-level search, for example, a primary search is excluded ST11. Here, if the remaining number is less than a predetermined number, for example, about a few, ST15 may be output as it is.

  In the case of a long term search or a wide technical problem, first, a plurality of specific persons in one population are extracted by a primary search, and then the remaining words in a secondary search that searches by related terms such as subordinate terms. Although the number of cases increases, ST1 to ST7 are repeated again to extract a specific person. This hierarchy is set at K, and ST12 to ST13 and ST10 to ST17 are repeated although explanation is omitted in the figure. As a result, even if the setting period is 20 years, if the technical problem is searched or narrowed down for the same category, the specific person name newly registered is close to zero because the person extracted in the previous stage is excluded. If technical issues are examined in this hierarchical system, extraction of related specific persons is almost covered.

  After the specific person is extracted by the specific individual selecting means 11, as shown in ST8 and FIG. 2 (b) ST21, the document created by the specific person is accessed again and extracted. Based on the specific person extracted by the specific person selection means, the input / output device 8 and the search expression generation means 10 perform a search by designating a specific person except for the technical problem of the specific item of ST1, and from the information server Is stored in the extraction result recording means 12. However, if a project that satisfies the previously extracted technical problem is related to the technical problem, it is related to the technical problem that the technical problem is that the symbol or related word is picked up separately and the document information of the specific individual. Is divided. In addition, the output result that is summarized in the output as the document information of this specific individual will be narrowed down gradually because the document information containing the specific individual described previously is excluded from the document information of the next specific individual It will be.

  This classification may be obtained by combining a search record including a technical problem such as a primary search and a specific person-created document extraction ST21, or an object of a technical problem of a primary or lower order as in ST22 for the latter. The related words may be searched again from similar word search or sentence similarity. This selection can also be supported from the input means. A part of the result is shown in the explanatory diagram of the list as a literature survey summary table in FIG. This summary table is sent from the sender who is the survey executor to the destination who is the survey requester. First, a time series, that is, the literature, is made up of members centered on the inventor D who is the creator of the literature information. They are organized in order of application date as creation date. After this No. 1 to 8, the next inventor, for example, the joint inventor, such as E, F, etc., excluding those that already included D, or the next highest number of cases like P, Q, etc. A new name will appear for the inventor. In this list, not only bibliographic items and contents such as document numbers other than the date of application and inventor, but also whether or not they are related to technical issues is described in US. The related words may be written here. In this list, since the creators are narrowed down, the minimum necessary document information is gathered by the output gathering means 13 ST23.

  However, in the list of FIG. 5, the time series for each specific individual such as the inventor and the author can be seen at a glance, but it is difficult to grasp the entire time series because all the extracted specific persons are listed in order. Therefore, it is good to regroup like the patent map of FIG. In FIG. 6, the survey period is described on the horizontal axis, and a specific person described as a team is described for each central member that is a specific individual extracted on the vertical axis. Individual names may be used as long as it is difficult to divide as a team. FIG. 5 and FIG. 6 are shown as an example, and other formats, for example, representations of three dimensions or higher, may be used instead of secondary representations. Further, after the result summarized by the output summarizing means 13 is displayed on the display means 6 via the control means 14, for example, the contents of the document information described in the list of the figure are transferred to a blank part in the map of the figure. By adding or deleting symbols from the input means, the device can be made easy to use, and the contents of the report that summarizes the literature information that is the output result is exactly what you think, more accurate, It will be possible to report in the content that you want.

  In the part corresponding to the vertical axis of the horizontal axis, the number of documents is listed for both the entire team or the like and the one corresponding to the technical problem. The document number may be described instead of the number of cases, and if a summary of the document contents is further described, the time-series movement can be understood only by this map. The list as shown in FIG. 5 and the time series map as shown in FIG. 6 compiled by the output gathering means are recorded in the recording means 15 and can be transmitted to the outside from the communication means 9 as necessary. Further, the result can be displayed on the display means 6 or recorded on the recording medium 7 via the result display / recording control means 14 and the input / output device 8.

  The procedure for extracting a specific person and outputting the document information created by the specific person in the flow shown in FIGS. 2A and 2B has been described. FIG. 3 illustrates the procedure in another flow. .

  In FIG. 3, a system in which the information investigation device 1 can be searched by START, for example, a personal computer is turned on and connected to the information server via the communication line 3, and a specific item can be input from the input means 5. This specific item has already been explained in the form for requesting the survey content in FIG. 4, but there are two specific item entry fields for generating a search expression by the search expression generation means, and for the primary search of these two items In the object column, in order to specify the target period of the search, for example, a survey period (b) such as the last 3 years or 20 years, an example of a specific range (b), and a technical problem (c) that is the research theme Is to be described. Depending on the information server to be accessed, it may not be necessary to enter a period, or it may be 20 years, which is the full range of machine search. Or if you want to get the latest technological trends, you can use the last 3 years. Examples of specific range (b) include the designation to be a public gazette of Company A and Company B as in Example 1, investigation from the name of an individual as in Example 3, or stopping this range designation, etc. good. On the other hand, if the technical problem corresponding to the research purpose of item 1 is described as much as possible with the classification code or keyword, the technical problem can be easily investigated.

  Further, in this example of the survey request form, the lower layer which is the secondary and subsequent searches for searching for multiple layers is described. In the example of FIG. 3, the secondary and subsequent searches are conducted with the survey request side according to the primary search result. The execution side consults or sets the contents of the search by looking at the primary survey result.

  First of all, in FIG. 3, if it is a specific item for search, for example, a trend survey of recent technological development, the type of document is specified such as a period of the past 3 to 5 years and then a public patent of a plurality of companies to be targeted. Furthermore, ST31 which inputs the keyword of a fuel cell as a technical subject, for example. Or, if it is an invalidation search of a patent that has been granted a right, it is a period of the entire searchable range, and then, including general literature, not limited to only the published patent gazette ST31 which inputs necessary keywords such as carbon dioxide gas refrigerant, supercritical refrigerant, etc. for the content to be aimed at. A search formula is generated by the search formula generation unit for the specific item input from the input unit 5, and a document describing a technical problem in the specified specific range is picked up from the information server via the communication unit 9. The extraction result recording means 12 is temporarily stored. The number of cases for each person name is extracted from the stored document information, ST32, the first specific person is set as ST33, and the person names in the order of the largest number are specified by the specific person setting means ST34.

  In FIG. 3, next, the joint author / joint inventor described in the literature information of the largest number of persons is identified in order ST35, ST36. In order to identify the large number of persons, it is easy to investigate, that is, to make the number of documents easy to grasp ST37, the number of persons as a population is set. n is the maximum number of persons to be investigated, and the number of document information does not necessarily exceed the maximum value in some cases because it includes persons specified in descending order and their co-inventors and authors. is there. For example, we will investigate about 20 people or less first, but in order to include joint inventors, first select the top 10 people in 4 years, the top 10 people in the latest year, and select in order from common superiors etc. A surveyable population is easily obtained. In other words, the maximum number of people here should be about n = 20. In addition, since the technical issues are narrowed down from the beginning, this number may not be reached in a short period of time, and the number of cases in which the person is specified from the stored number of cases can always be displayed on the display means 6. For example, it is possible to specify the total number of persons extracted by inputting the maximum number n from the input means 5 while grasping the number of remaining cases. ST34 to ST37 are repeated, and the specific person is collected and taken over to the next step ST38.

  After the specific person is extracted by the specific individual selecting means 11, as shown in ST38 and ST39 in FIG. 3, documents created by the specific person are accessed again and extracted. At this time, the search formula is slightly changed, and based on the specific person extracted by the specific individual selection means, the input / output device 8 and the search formula generation means 10 can search for the specified period except for the technical problem of the specific item of ST31. The document information from the information server is stored in the extraction result recording means 12. However, if a project that satisfies the previously extracted technical problem is related to the technical problem, it is related to the technical problem that the technical problem is that the symbol or related word is picked up separately and the document information of the specific individual. Is divided.

  This classification may be performed by combining the search records including the technical issues performed in ST31 and ST32 with the searches ST38 and ST39 not including the technical issue of extracting the specific person, that is, adding symbols or the like together. The latter, that is, the document information that does not include the technical problem may be searched again from the similar word search or the sentence similarity for the technical problem as in ST40. This selection can also be supported from the input means. A part of this result has already been explained in the list explanatory diagram of the literature survey summary table of FIG. This summary table is summarized in time series, that is, in order of the filing date as the document creation date, with members centered on the inventor D who is the creator of the document information, such as the filing date and the document number other than the inventor. Not only bibliographic items and contents, but also the classification of whether or not it is related to technical issues is described in US. Here, words related to the technical problem may be described. In this list, the creators are narrowed down in the order of the largest number of items, and those that will be described later are excluded from the already-registered document information, so that the minimum necessary document information is collected by the output summarizing unit 13 ST41.

  Further, ST41 is regrouped as in the patent map of FIG. In FIG. 6, the horizontal axis indicates the survey period, and the vertical axis indicates a specific person described as a team for each central member that is a specific individual extracted. Naturally, it is possible to change the way of taking it in multiple dimensions instead of two dimensions.

  If a summary of the document contents is described at the position corresponding to the number of documents and the document number at a position corresponding to the vertical axis of the horizontal axis in FIG. The list as shown in FIG. 5 and the time series map as shown in FIG. 6 compiled by the output gathering means are recorded in the recording means 15 and can be transmitted to the outside from the communication means 9 as necessary. As a result, if the survey requester is the information survey device 2 shown in FIG. 1 and the survey performer is the information survey device 1 connected via the network 3, the survey requester and the survey performer transmit and receive via the network 3. ST42 becomes possible. In both information investigation apparatuses 1 and 2, the result display / recording control means 14 and the input / output device 8 can be displayed on the display means 6 or recorded on the recording medium 7.

  As described above as the feature of the present invention, the stage before the primary search in FIG. 2 and the consultation with the survey requester in FIG. 3 can be a trial stage, which is easy to see as shown in FIGS. In addition, it is possible to examine the survey results using a list or map generated in a focused range, and lead to the next search.

  For this reason, in this invention, paying attention to the activity of the individual who is continuously in charge of development, the literature information including the patent application of the specific individual is collected in time series regardless of whether or not including the technical problem. As a result, the document information related to the technical problem but not extracted by the search formula can be examined before and after the document information classified as including the technical problem. For example, even if a range of similar terms can be searched for in the specific item of carbon dioxide refrigerant, it is conventional to use a term such as a higher natural refrigerant or treat it as an apparatus invention without describing the type of refrigerant. If the search system cannot be surveyed, or if the range of the classification code is expanded too much to obtain this range, the survey includes too much noise, and the number of examinations increases, which only increases the burden of period and cost. Furthermore, in the search for fuel cells, literature information on materials alone, such as ion exchange membranes that do not include relevant terms, literature information on water vapor permeable membrane alone technology used in steam reforming technology, and the structure of countermeasures against heat generation are included in the literature. Even if there are no terms related to fuel cells, it can be easily grasped by investigating the process of following activities in this time series.

  In FIG. 3, the survey requesting side and the survey execution side transmit and receive, and ST42, and by reexamining the search specific item, ST43, a highly accurate search can be repeated again from ST31. Further, it is also possible to continue the investigation for the number of cases where the number of persons / cases has been further extracted, but the specific person has not yet been extracted, as the search specific items need not be reviewed. In addition, these operations may be performed without the consultation ST42 transmitted and received by the survey requester and the survey performer. That is, after generating a result such as a document map, the remaining number of investigations ST44 is performed, and if there is an item to be investigated, the information investigation apparatus 1 is used to continue the investigation or ST45, and output to end END. All of this can be done alone, including a trial and subsequent follow-up. In addition, the survey execution side who received the survey request form in FIG. 4 can independently perform trials and subsequent continuation surveys independently while judging the communication entry fields such as the survey purpose. Further, the survey requesting side may use the information surveying apparatus 2 to perform a high-accuracy search later separately from the request by only receiving the trial result. It is also possible to continue the survey for a later period only. That is, the search of the present invention can be performed easily and accurately by anyone at any time and anywhere, and a search for grasping the development progress.

  If there is a specific person to be examined in the present invention, if the person name is first set as a specific item in the trial, the search shown in FIG. 2 and FIG. In that case, a list including coauthors will be required. In addition, the technical problem is set as a fuel cell in the trial, and from the literature information including the technical problem extracted by this trial, a frequently used term, for example, the word “water vapor permeable membrane” is used in one document. It is also possible to automatically extract that it is used for a plurality of documents in ST22 of FIG. 2 and add the word as a specific item or a specific technical problem in the next search stage to continue the search again. That is, these re-searches may be performed by a person or a method of automatically extracting words.

  Even when the survey execution side conducts the survey as a business, the search system program described in the flowcharts of FIGS. 2 and 3 may be distributed over the network 3. On the program user side, it is possible to search freely by accessing the database on the survey execution side distributed by the distributed search program. In this case, it is possible to improve the accuracy of the search by consulting with the survey expert through communication with the survey execution side such as ST42 and ST43.

  You may connect to a general server from the distributed program. As a result, it is possible to easily connect to a wide and rich database such as a database related to general literature or a database provided in a foreign country. In that case, the program distribution side can collect a fee for downloading, collect it for advertising costs, and provide an answer at a low cost each time it is consulted.

  If there is such an application software provider, it will be possible to search freely what researchers like university students, regardless of science or literacy, can use the database effectively at a low cost. The progress of research and the effectiveness of information exchange can be further improved.

  The present invention includes an input means 5 for inputting a specific item for generating a search expression, an extraction result recording means 12 for recording document information extracted from a server based on the generated search expression, and the extracted and recorded document information. Specific personal selection means 11 for selecting a specific individual who is the author or the inventor, and output of document information created by the specific individual selected by the specific personal selection means from the server and output in a time series Since it is provided with the summarizing means 13, it is possible to take a glance at the results of the activities of the individual, and to grasp a more sure development trend since a plurality of individuals are gathered as this individual. That is, the present invention does not search for specific research contents by word or sentence for the purpose, but pursues the individual to narrow down the individual research contents from the whole to a specific one. The target is narrowed down to the whole from the pursuit and search of the research, and furthermore, it is possible to pursue all as a result while limiting the scope to be examined in the narrowing process, and it is easy It is possible to obtain an investigation device and method that can be obtained with certain procedures reliably.

  In the present invention, the specific item input by the input means 5 can specifically include at least a preset name of a specific individual or a subject such as a technology to be investigated, particularly a content to be investigated, and narrows the scope of the investigation. The result is easy and easy to study.

  In the present invention, the specific individual selecting means 11 selects a plurality of specific individuals in the order of the number of documents, and extracts the specific number of persons set in advance to the output summarizing means 13, so in one stage The examination range, that is, the amount of documents can be narrowed down, and the search can be simplified.

  Since the specific individual in this invention includes a co-author or co-inventor, it is easy to grasp the progress of development and research and technical trends, and can prevent omission.

  In the present invention, the selection of the specific individual in the specific individual selection means 11 is provided so as to be repeated a plurality of times, and the specific individual is selected in the selection of the specific individual in the specific personal selection means 11 and the specific individual is excluded next time. Even if it continues, the amount of literature information can be narrowed down and the study can be made easier. The specific individual selecting means 11 is used for grasping a document extracted by searching for a person's name from the document information selected in the technical problem, or selecting a specific person having a large number of cases regardless of a specific range, Since it is only necessary to select a specified specific person or a person related to the extracted person, the search is performed only by specifying the person, so that the search can be performed easily and reliably.

  The specific item input by the input means of the present invention is formed so as to be inputable in a plurality of hierarchies, and after searching for the specific item of the previous hierarchy, the related items are different from the problems such as the technique of the previous hierarchy. Since the next search is performed using the specific item, which is a problem such as the above, a document is extracted and a specific individual other than the selected specific individual is selected, the search population can be narrowed down and the survey is simplified.

  The result summarized by the output summarizing means 13 of the present invention includes the document contents or the contents of the document information for each specific person or the number of cases together with the time series, so that an easy-to-read format and an output that can be easily judged are obtained.

  It is possible to determine that the output related to a specific person collected by the output summarizing means of the present invention is a document in which a specific item is described, and for each individual, each team, or a university or laboratory designated by a specific item It is easy to distinguish research trends and development trends because they are compiled for each company.

  The present invention extracts document information based on a search formula generated by a specific item related to information to be investigated, selects a specific individual who is an author or an inventor from the extracted document information, and creates the selected specific person Since the reference information is gathered in time series and a specific individual is a plurality of teams or a plurality of teams, a search can be performed with a small number of search procedures.

  According to the present invention, when selecting a specific individual, the number of selected persons is limited to suppress the amount of information survey, so that the contents of the document information can be grasped reliably in a short time.

  When extracting bibliographic information of the present invention, search in multiple stages and specific items to be searched in the next stage will expand the scope of the search using terms such as higher concepts or related actions than in the previous stage, so prevention of survey omissions Can be done easily.

  When extracting the literature information of the present invention, the search is performed in a plurality of stages, and the specific items to be searched in the next stage are narrower than the previous stage by using lower concept terms or combination terms. Even if there are too many names and cases, it is possible to narrow down the scope and divide the survey, so that the target survey can be performed without hindering the search.

  The present invention makes it possible to input a plurality of specific items for generating a search formula for information to be investigated, extracts literature information based on the search formula generated by the specific item of the upper layer first, and extracts the extracted literature information Select a plurality of specific individuals who are authors or inventors from the above, summarize the literature information created by the selected specific individuals in time series, and then based on the search formula generated by the specific items of the lower layer, and Since the document information created by a specific individual excluding the specific individual already selected is extracted, an easy-to-handle search system can be obtained.

  The amount of literature information extracted at each stage or each layer of the present invention is limited by the number of specific individuals selected. Furthermore, when setting specific items in multiple layers, the lower layer specific items must be input at the same time as the upper layer specific input, or input after document extraction by the upper layer specific items. Selectable. This allows us to conduct a user-friendly survey.

  In the present invention, the requester who requests the survey side for information survey sets specific items, and can communicate to the survey side about the search start of the next step in the multiple steps or the lower layer of the multiple layer specific items. Therefore, it is possible to surely investigate the contents to be investigated.

  Since the investigation side conducting the information investigation of the present invention can communicate with the requesting side about recognizing a specific item before performing a search of a lower layer of the next step or a plurality of layer specific items of a plurality of steps, In addition, it is possible to investigate as requested by the user, and processing in the shortest time becomes possible.
