Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document which allows a client to quickly search for a plurality of document files stored in a file server or the like to be browsed and which meet a predetermined condition from a client side and obtain a search result. Related to file search system.

[0002]

2. Description of the Related Art In recent years, a server-client type network in which a plurality of computers are connected to a network by assigning specific roles has been generalized as a usage form of a computer in an office using the computer. For example, there is a use method in which a computer installed in each department is connected to a network as a client, and a read-only or readable / writable document file is stored in a file server connected to the same network and shared by each client. Can be

Under such circumstances, especially in hospitals, the medical chart is converted into a document file and stored in a storage means such as a file server. If necessary, a client of each department searches for a file of the medical chart stored in the storage means. Extract,
There is a movement of so-called electronic charts that allow clients to browse file contents. In the case of such electronic medical records, the number of document files to be searched is expected to be enormous (more than 10 million in five years in the case of university hospitals). Search methods are needed. In addition, a client of a hospital network or an external client via the Internet or the like is required to acquire a document file extracted as a result of a search from a storage unit and easily display and browse the document file.

[0004] In the case of searching for a document file containing desired contents from a huge amount of stored document files, such as the case of an electronic medical record at a hospital, a conventional full-text search system and a relational database have been used. (Hereinafter, abbreviated as RDB) was generally used.

[0005]

The conventional file search system has the above-mentioned configuration. Among them, the former full-text search system simply judges whether there is a corresponding character in a document or not. I have. Since the index for full-text search is not aware of the document structure and tags, it has the feature that no design change is required even if new items or tags are added to the document contents. However, in general, full-text search uses only the number of appearances and locations of words and phrases when determining the relevance of the search, and it is not possible to narrow down the search targets in advance. In addition to the large number of processes, the search accuracy is limited, and there is a problem that the search takes a long time, for example, it is necessary to repeat narrowing down many times to reach the target document file.

On the other hand, the conventional search system using the RDB has a high degree of freedom in design, can create a search index suitable for a specific data pattern in advance, can limit the search range, and can operate at high speed. However, because the schema (database specification) is fixed, it is not possible to store data other than the pattern assumed at the time of database design in the document file, or to search for such data parts. However, there is a problem in that there is a problem in scalability and design change is difficult.

[0007] In addition to the problems of the conventional search system, in searching for a huge amount of stored document files, the entity of the document file is searched every time from a huge number of search targets. Therefore, it is not possible to expect satisfactory high-speed performance, and it is necessary to set an efficient search index for searching at a practical speed. Particularly, particularly in an electronic medical record, there is a very high possibility that a new item will be generated in a document file as a medical record as the medical technology advances or the content is added by adding or changing a rule. For this reason, a search system is required to have the flexibility to make it unnecessary to modify a program or rebuild a database even when a new item is added.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problem. A document is stored as a highly scalable document file described in XML, and the contents of the document file are searched for in a directory service based on LDAP. Register properly as index information and LD from client side
An object of the present invention is to provide a document file search system capable of causing a search server to execute a search based on an AP and efficiently searching for a required document file at high speed.

[0009]

A document file search system according to the present invention includes a predetermined search directory server based on LDAP and a plurality of documents described in XML and stored in a predetermined file server or storage means. File, respectively, and sets an entry in the directory for each of the document files based on the LDAP for the search directory server, and a tag included in each document file as an attribute of the corresponding entry. LDAP registration means for registering and further registering a character string in the tag as a value of the attribute;
A file search request by LDAP for the document file which is connected to the search directory server via a network and whose entry is set in the search directory server is given to the search directory server based on a user's instruction, A search client that receives the search results obtained by the search directory server and presents the results to the user.

As described above, according to the present invention, a search directory server using LDAP, an LDAP registration means for setting an entry in a directory of the search directory server for each of the document files,
In addition, a file search request is provided to the search directory server based on the user's instruction, a search client that receives the search result and presents the search result to the user is provided, and the tag of the document file described in XML and the tag in the tag are included. By registering a character string as an attribute and an attribute value in an entry corresponding to a document file and performing a search using a general-purpose LDAP search filter, a tag having a meaningful tag and an entry consisting of a character string in the tag are obtained. A document file that contains the desired content from a huge number of document files that can be easily and efficiently searched with attributes and their values as search conditions, can perform search easily and efficiently, greatly improve the hit rate in search and improve search efficiency Can be searched at high speed.
Further, since the document file is described in XML, even if a new item is added to the document file, the added portion is recognized as a tag and a character string by the LDAP registration means as it is, and the attribute and the attribute value in the entry are changed. It is only necessary to simply add, and it is possible to flexibly cope with newly added items while eliminating the need to modify the program and the like, and it is excellent in extensibility.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. The present embodiment shows an example in which the present invention is applied to a so-called electronic medical record in which a medical record is stored in a server as a document file and used. This figure 1
FIG. 2 is a block diagram of the document file search system according to the embodiment, FIG. 2 is an explanatory diagram of an entry registration state in the document file search system according to the embodiment, and FIG. 3 is a diagram illustrating a directory registration process of the document file search system according to the embodiment. The first half flowchart, FIG. 4 is the second half flowchart of the directory registration process of the document file search system according to this embodiment, and FIG. 5 is the file content display process flowchart of the document file search system according to this embodiment.

In each of the drawings, the document file search system 1 according to the present embodiment uses an XML (Extensible Mars).
a file server 2 for storing and managing a plurality of document files described in a Kup Language (LDAP),
A document file is read from a predetermined search directory server 3 that provides a directory service based on the "ight directory access protocol" and a file server 2, and an entry 20 in the directory is stored for each document file in the search directory server 3 based on LDAP. LDAP for setting and registering the attribute of the entry 20 and the value of this attribute according to each document file
The registration means 4 is connected to the file server 2 and the search directory server 3 via a network, and receives a file search request based on a user's instruction.
And a search client 5 that obtains a document file from the file server 2 and displays the content in a predetermined display format based on an instruction of a user who has confirmed the search result obtained by the search directory server 3. It is a structure provided with.

The file server 2 has a mechanism for transmitting and receiving information such as files to and from a search client 5 connected to a network based on HTTP. To the document file stored in the file server 2, a predetermined tag indicating the type of the document content (such as a medical chart or a general office document) and a character string in this tag are added in advance as document type information. Also, the file server 2 has X
Attached information files, which are separate files from the document file, such as images and charts included in the image when the document file described in ML is actually displayed, are stored together with the document file, and the document file is searched. When transferring to the client 5, the data is transferred together.

The search directory server 3 is a well-known directory server that provides a directory service based on LDAP to each client connected to the network, and the search client 5 is used for search instructions and search results based on LDAP. Send and receive information such as
While providing the search function to the search client 5, the LD
The AP registration unit 4 receives an operation such as creation and addition of directory information.

The LDAP registration means 4 reads out the document files stored in the file server 2 in advance, and sends an LDA to the search directory server 3.
An entry 20 in the directory is set for each of the document files based on P, a tag included in each document file is set as an attribute of the corresponding entry 20, and a character string in the tag is set as the attribute. These are registered as attribute values (see FIG. 2). Each information of the document file registered in the search directory server 3 by the LDAP registration means 4 becomes an index in the search.

The search client 5 receives an LDA for the document file in which the entry 20 is set in the search directory server 3 based on a user's instruction.
P, a file search request is given to the search directory server 3, and the search result obtained by the search directory server 3 is received and shown to the user. A document file is obtained from the server 2, a style sheet set corresponding to the document file is also obtained by the file server 2, and the contents of the document file are displayed in a display format based on the style sheet.

The search client 5 is provided with predetermined user identification information (such as an ID code) when the user starts using it.
To the user, obtain the user identification information through the user's input, and refer to the tag and the character string as the document type information of the document file transferred from the file server 2 to perform the use. A predetermined style sheet corresponding to the user identification information, the tag, and the character string is selected from a plurality of style sheets prepared in the file server 2 and transferred from the file server 2 to the search client 5.

The API used when the user sets a search condition as a stage before the search client 5 issues a file search instruction to the search directory server 3 is LD.
The standard functions of the AP are used as they are. The search client 5 is directly connected to the file server 2 and the search directory server 3 via a network, and is also connected via an external network such as the Internet with a predetermined access restriction as required. May be possible.

Next, a file search / browsing process in the document file search system based on the above configuration will be described. First, a directory registration process as a preceding stage of the search will be described with reference to flowcharts shown in FIGS. As a premise, prior to this directory registration process, all the document files to be searched and browsed are X
It is assumed that the file is stored in the file server 2 in a file format described in ML.

As the directory registration process, first, L
The DAP registration means 4 determines whether or not any of the document files stored in the file server 2 has not been registered in the search directory server 3 (step 101). If there is, one of them is read from the file server 2 (step 102).

With respect to the read document file, LD
The AP registration unit 4 refers to the tag in the document file to determine whether or not this tag has not been referred to before and this time is the first reference (step 103). In this case, the referenced tag is acquired and stored in the predetermined storage unit 6 (step 104). In addition, LDA
The P registration means 4 refers to the character string corresponding to the previously acquired tag, and determines whether or not this character string has never been referred to before and this time is the first reference (step 10).
5) If it is the first reference, the character string referred to is acquired and stored in the storage means 6 (step 106).
After step 106, the process returns to step 105,
Repeat the process. If all the character strings corresponding to one tag have already been referred / acquired once in step 105, the process returns to step 103, and the subsequent processing is repeated.

In step 103, if all the tags in the read document file have been referred to and acquired, the LDA
The P registration means 4 determines whether or not tags which are required attributes for registration in the search directory server 3 are all stored in the storage means 6 and entry registration is possible (step 1).
07) If registration is possible, LDAP registration means 4
Registers the entry 20 of the read document file in the directory of the search directory server 3 based on LDAP (step 108). If registration is not possible in step 107, the process returns to step 101, and the subsequent processing is repeated.

Subsequently, the LDAP registration means 4 determines whether there is an unregistered tag which is not registered as an attribute of the entry yet in the entry 20 of the registered document file by the tag stored in the storage means 6. Judgment (Step 10
9) If there is an unregistered tag, the unregistered tag is added to the entry 20 as an attribute (step 110), and a character string corresponding to the tag stored in the storage unit is set as a value of this attribute. Add (Step 11
1). After the step 111, the process returns to the step 109 and the process is repeated. In step 109, the storage unit 6
Are registered as attributes of the entry 20 and there is no unregistered tag, the flow returns to the step 101 and the subsequent processing is repeated.

If there is no document file registered in the search directory server 3 in the file server 2 in the step 101, a series of processing is terminated. In this way, all the document files stored in the file server 2 are stored in the search directory server 3 as entries 20 and 20 as search index information.
Search and document content display processing are performed in a state in which the attribute and its value are registered. In the search processing, a known LD that issues an LDAP search filter from the search client 5 and the search directory server 3 guides the search result.
It is based on the AP and will be described only briefly.

In this search, when a user inputs a search condition combining a tag and a character string to the search client 5 through the input means 5a and instructs a search start, the search client 5 sends the search condition to the search client 5. It is sent to the directory server 3. Based on the search conditions from the search client 5, the search directory server 3 refers to the search index information of each document file registered by the LDAP registration means 4 and extracts the requested document file name. The search result is transferred to each search client 5 requesting the search result as a search result. When the user uses the search client 5 for a search, an operation of inputting predetermined user identification information (ID code or the like) and logging in to the search client 5 is required. The user identification information input at this time is temporarily stored in the search client 5.

Further, a file content display process for browsing a document will be described with reference to a flowchart shown in FIG. In advance, the search client 5 receives the search result transferred from the search directory server 3 and displays it on a predetermined display means 5b. Based on the contents, one or a plurality of documents which the user wants to browse The file is instructed.

Based on the operation of the user, the search client 5 requests the file server 2 to transfer one or a plurality of document files extracted as a search result, and reads the document file transferred from the file server 2. (Step 201). For the read document file, the search client 5 determines whether or not the file contains a tag indicating the document type as document type information (step 20).
2) If there is a tag, the character string of the corresponding tag portion in the document file is acquired as the setting value of the document type (step 203).

Further, the search client 5 derives style sheet setting information for defining the display state of the document file from the acquired document type setting value and the previously stored user identification information (step 204). . In this setting information, it is determined whether or not a specific style sheet is associated with the document file (step 205), and one of the style sheets prepared in the file server 2 is associated. In this case, the corresponding style sheet is set as a style sheet to be applied to the document file, and a transfer request for the style sheet is made to the file server 2 (step 206).

If there is no tag indicating the document type in step 202, and if a specific style sheet is not associated in step 205, the default style sheet is set as a style sheet to be applied, and A request for transferring the style sheet is made to the server 2 (step 207). Step 206
And 207, the search client 5 reads the style sheet transferred from the file server 2 (step 208), and the search client 5 displays the contents of the document file on the display means 5b based on the style sheet (step 208). 209), and a series of processing ends.

The search client 5 displays the contents of the document file on the display means 5b based on the style sheet transferred from the file server 2, and the user can browse the contents of the document file through the display means 5b.
A document file described in XML can be appropriately displayed in any environment based on a style sheet.
The user can easily understand the contents of the document file.
In addition, the content of the document file is displayed based on the style sheet corresponding to the user identification information and the tag indicating the document type at the same time, and the display image of the document file is partially or entirely displayed for each user or each document file type. By being able to display differently, the same document file can be handled for various users, and various types of document files can be handled in the same format, eliminating the need to prepare multiple document file contents and document formats. In addition, the creation and management of document files becomes remarkably easy.

As described above, in the document file search system according to the present embodiment, the file server 2 storing the document file, the search directory server 3 using LDAP, and the entry 20 in the directory of the search directory server 3 And the LDAP registration means 4 for setting a file search request to the search directory server 3 based on the user's instruction and receiving the search result and presenting the search result to the user. Arrange each, XML
Since the tag of the document file described in the above and the character string in the tag are registered as the attribute and the value of the attribute in the entry 20 corresponding to the document file, the search is performed using the general-purpose LDAP search filter. Searches can be performed easily and efficiently by using the attributes and values of the entry 20 consisting of the character strings in the tags as search conditions, and the hit rate in the search can be significantly improved, the search efficiency can be increased, and a huge document file can be obtained. You can quickly search for a document file containing the desired content from within. Also, since the document file is described in XML, even if a new item is added to the document file, the LDAP registration means 4 recognizes the tag and character string of the added portion as it is, and It is only necessary to simply add a value, and it is possible to flexibly cope with a newly added item, and the extensibility is excellent. In particular, by making the medical chart an XML document file, it will have the flexibility to be able to respond to new tags that occur as needed with the advancement of medical technology and the addition of content due to the addition or change of regulations, and will be used as a medical chart. There are no restrictions, and it is possible to realize not only a substitute for paper charts but also a significant increase in business efficiency.

In the document file search system according to the above-described embodiment, the medical record is searched as a document file. However, the present invention is not limited to this.
If it is a document file described in ML, contents other than the medical record may be used. The search is performed in the same manner as described above, the document file is transferred from the file server 2 to the search client 5, and the contents can be browsed by the search client 5. Further, the document files are all stored in the file server 2, but the present invention is not limited to this, and the document files may be distributed to a plurality of servers and storage units.

In the document file search system according to the embodiment, the LDAP registration means 4 stores the entry 2 in the directory of the search directory server 3.
0 is set to correspond to each document file in a one-to-one correspondence. However, the present invention is not limited to this configuration. As shown in FIG. , Patient name, document type, etc.) and the character string in the tag, and the entry 20 for each document file is set as a lower entry and divided into a plurality of sets according to the difference between the common tag and the character string. Are set separately, and the entry 2 for each document file is set in the directory of the search directory server 3.
0 may be arranged in a hierarchical structure according to the characteristics of the document file, and the narrowing down according to the conditions at the time of the search may be performed by the upper entries 30, 40, and the lower entries having the entry 20 of the document file having the same characteristics. By referring to the 50 attributes and their values, the search can be performed quickly, the search can proceed more efficiently, and the search time can be further reduced.

In the document file search system according to each of the above-described embodiments, transfer for reading a document file between the search client 5 and the file server 2 is performed based on HTTP, and the transfer is performed within a facility such as a hospital. However, the configuration is such that information can be obtained without being conscious of the outside. However, the present invention is not limited to this. When the search client 5 and the file server 2 are located in a network closed inside, such as in a hospital, another communication protocol is used. In this case, a document file or the like can be transferred on the basis of the security, and security such as confidentiality can be further enhanced.

In the document file search system according to the above-described embodiment, the file server 2 and the search directory server 3 are configured as individual servers, and the respective services are processed in a distributed manner. The file server 2 and the search directory server 3 may be integrated, and each server may perform the functions of the file service and the search directory service. Furthermore, the LDAP registration means 4 can also be configured to be integrated as one function in either the file server 2 or the search directory server 3 or a server in which these are integrated.
The initial cost can be further reduced when the network to be applied is a small scale that does not require distributed processing of various services.

Further, in the document file search system according to the embodiment, a document file described in XML is stored in the file server 2 in advance from the beginning. However, the present invention is not limited to this. As shown in FIG. To
A main server 7 for storing and managing document files in a predetermined file format other than the XML format;
File monitoring means 8 for determining whether a document file is newly added by referring to the file at predetermined time intervals, and a file conversion means for converting the document file determined to be added by the file monitoring means 8 into an XML format. The file monitoring means 8 refers to the creation date and time of a document file in a predetermined file format stored in the main server 7 in advance at predetermined time intervals as a preparation process prior to the file search process. It is determined based on the context of the date and time and the reference date and time whether or not one of the document files has been added from a predetermined time before to the reference time. If added, the file monitoring unit 8 has determined that the document file has been added. The file conversion means 9 converts the document file into a file format described in XML, and converts the converted XML document file into a file format. A new storage mechanism can be used to store documents in a wide range of file formats, such as a file format that is easy for the document creator to create, and a document file search / browsing function has been added to another file management system. It can also be used to enhance the search and browsing functions of existing systems.
