Abstract

PROBLEM TO BE SOLVED: To provide an information processing apparatus, an interest information provision device, and an interest information provision method and program, for easily acquiring information that draws interest of a person, on the basis of content that the person was involved in creation.SOLUTION: When a verb extracted from document data is an interest word stored by a person in an interest word storage means 11, an information processing apparatus 10 searches information by information search means 14 by using a noun set with the verb extracted by set extraction means 12 as a key word. There is no need to register in advance the noun to be paired with the verb as the interest word on context.

Description

  The present invention relates to an information processing apparatus, an interest information providing method, and an interest information providing program for presenting information of interest to a person.

  Various products exist so that the actual store overflows. In addition, stores on the web using the Internet are expanding, and users can easily purchase relatively rare products and nonstandard products that are difficult to obtain in actual stores.

  On the other hand, many consumers are busy with their lives, and may forget the time to purchase goods. In addition, even when the purchase time approaches, there is often no time to go to the actual store, and there are many cases where a product that can be obtained more easily than the originally planned product is purchased.

  Thus, as a first related technique of the present invention, an information providing server that appropriately recommends a product suitable for a user of a device such as a mobile phone has been proposed (see, for example, Patent Document 1). In the first related technique, keywords that match the user's preference are extracted from the work information of the broadcast program acquired by the user. When extracting the keywords, a morpheme analysis technique is used to decompose the text portion of the content data into morphemes described later based on grammar and dictionary data (paragraphs 0050, 0061 to 0069, FIG. 11).

  In the first related technology, attribute information related to the extracted keyword is searched from the product data storage unit, and product recommendation data including a product ID corresponding to the attribute information is output. Therefore, by using the first related technology, it becomes possible for the preference extraction unit to search for and present products and services that meet the user's preference. However, when the first related technology is used, there is a response to a case where product information for a person other than the user is searched for and presented as in the case of recommending a product to a user's acquaintance or giving a present. Have difficulty.

  Therefore, as a second related technique of the present invention, it is proposed to obtain a word of interest of a specific person other than the user from a document such as an e-mail and provide related information based on the word. (For example, refer to Patent Document 2). This second related technique also employs a technique of morphological analysis (page 14, line 14 to line 15, page 15, line 15 to line 23, page 16, line 3). Eyes to 7th line, page 24, 46th line to 50th line).

  Here, morphological analysis refers to a process of dividing a sentence into idioms or words of the smallest unit having meaning. Therefore, if the corresponding sentence is like a purchase order sent from another person on a mobile terminal, idioms and words decomposed by morphological analysis are important keywords for searching for information about products. There is a great possibility. However, even when morphological analysis is performed on sentences other than these sentences, the idioms and words obtained as a result are highly likely to be completely unrelated to the product to be purchased. The result is likely not to contain useful information.

  Therefore, in the first related technique described above, the preference extraction unit uses preference information data. In the preference information data, a plurality of keywords, keyword types, priorities, and update dates / times are associated with the device ID as a key. For example, when the target device is a television recording device, “documentary” or “variety” is registered as preference information data as the genre of the broadcast program. As a keyword, for example, “stuffed toy” is registered as preference information data. Thereby, the information (here, a television program) related to the preference information data can be acquired when the common phrase or word decomposed by the morphological analysis matches the registered preference information data.

  On the other hand, in the second related technology, an interest word as a word corresponding to the user's interest is extracted from a document acquired by sending and receiving an electronic mail, and a database of interest data is created. This interesting word is a noun in the case of the second related technology. Therefore, in the second related technology, interest words are registered as nouns in the database of interest data one by one, compared with idiomatic phrases and words decomposed by morphological analysis, and the interest word vectors are extracted. Based on this, interest data is created.

JP 2009-111181 A Republished patent WO2003 / 083723

However, in these first related technology and second related technology, idiomatic phrases and words decomposed by morphological analysis are compared with nouns such as words registered in advance as showing interest. For this reason, when it does not correspond to the noun registered beforehand as what shows interest, the information regarding it cannot be acquired. For example, users can register nouns in areas that show their interests, but it is impossible to register many nouns in the database so that they can predict areas that show other people's interests in advance. It is.

  Of course, it is possible to register all nouns in the database as objects of interest. However, if a database such as such a lexicon is prepared, many idiomatic phrases and words decomposed by morphological analysis will hit this database. Therefore, information on all products and the like is provided, and the user has no benefit of obtaining the selected information.

  <Embodiment of the Invention>

  Next, an embodiment of the present invention will be described.

  FIG. 7 shows a state in which a communication terminal as an information processing apparatus according to the embodiment of the present invention is connected to the Internet. The communication terminal 100 according to the present embodiment includes a communication unit 111 that transmits and receives data by connecting to the Internet 101. Moreover, the search request input part 112 as an input device at the time of searching for the goods in which a specific person is interested is provided. The search request input unit 112 is constituted by a keyboard, for example.

  The search request input unit 112 is connected to the search request unit 113. The search request unit 113 is connected to the content storage unit 114, the interest target extraction unit 115, and the product search unit 116. Among these, the search request unit 113 selects content to be searched from the content storage unit 114 based on the information input from the search request input unit 112. Then, based on the selected content, a request is made to the interest extraction unit 115 to search for a product that is of interest to a specific person related to the user of the communication terminal 100. Here, the content is content expressed as digital data, and includes sentences such as e-mails and words included therein. Specifically, the content storage unit 114 stores content created or obtained by the user, such as e-mails, to-dos (ToDos) in which information to be done, schedules, and telephone books are recorded.

  The interest extraction unit 115 analyzes the content selected by the search request unit 113 and extracts a set of nouns and verbs. If the extracted verb contains a meaning indicating interest, a search for a noun is requested. The interest extraction unit 115 is connected to the interest dictionary 117, and is used for checking whether or not the extracted verb has an interest meaning. In the interest dictionary 117, various verbs having the meaning of interest are registered in advance. The user can add or edit the contents of the interest dictionary 117 as necessary, using manual input or a communication means such as a memory card (not shown) or the Internet 101.

  The product search unit 116 is connected to the communication unit 116 and the search result presentation unit 118. The product search unit 116 searches, for example, the Internet 101 for product information and product acquisition locations according to data input by the user from the search request unit 113. The search result presentation unit 118 is configured by, for example, a liquid crystal display, and displays the result of the search performed by the product search unit 116.

  The communication terminal 100 shown in FIG. 7 includes a CPU (Central Processing Unit) (not shown) and a storage medium storing a control program executed by the CPU. At least a part of each unit such as the communication unit 111 can be configured by a functional unit that is realized in software by a CPU executing a control program.

  FIG. 8 shows a state of a search process for a product in which a specific person is interested in the present embodiment. This will be described with reference to FIG.

  The search request input unit 112 of the communication terminal 100 illustrated in FIG. 7 waits for a search request to be generated (step S201). For example, it is assumed that the user is initially set as a condition for searching for the communication terminal 100 when the user receives an e-mail. In this case, a search request is generated every time the communication terminal 100 receives an email (Y).

  Unlike such an example, the user of the communication terminal 100 may perform initial setting of the search so that a search request is generated based on the relationship between the e-mail received in the past stored in the content storage unit 114 and the sender. it can. Here, an example will be described in which an e-mail search request is made using the search request input unit 112, for example, in order for the user to search for products that are interested in Mr. A. In the case of this example, in the process of step S201, the user designates an e-mail from Mr. A as content, and requests a search for a product having an interest of Mr. A.

  Based on the search request input from the search request input unit 112, the search request unit 113 acquires an e-mail sent from Mr. A as the search target content from the content storage unit 114 (step S202). Then, the title and text of the e-mail are analyzed using grammar to extract all noun and verb sets (step S203).

  The search request unit 113 initializes the parameter V for processing one verb at a time in the extracted noun and verb set to “1” (step S204). First, it is determined whether or not the first verb (V = 1) is a verb used when a person shows interest (step S205). For example, any of the interesting words as verbs used when a person who has been registered in advance in the search request unit 113 indicates interest, such as “like”, “want”, “want to buy”, “want to buy” If they match (Y), the product search unit 116 searches for product information related to the noun that is set in the verb (step S206).

  For example, if there is a sentence “I want to buy a fountain pen” in the e-mail sent from Mr. A as content, the noun “fountain pen” and the verb “I want to buy” are set. Therefore, assuming that the verb “I want to buy” or “Buy” corresponds to an interesting word, the product search unit 116 searches for product information related to the noun “fountain pen”.

  When the corresponding product information exists in the mall on the Internet 101 in this way (step S207: Y), the product search unit 116 stores the product information in the temporary storage area of the storage medium (step S208). ). Product information includes product candidates categorized by user type, such as gender and age, general descriptions of products, names of stores that handle such products, telephone numbers, URL (Uniform Resource Locator), etc. Various types of information are included.

  When the above processing for one verb is completed, the search request unit 113 determines the magnitude relationship between the maximum value VMAX of the number of verbs in the noun and verb set extracted in step S203 and the number V of the currently processed verb. Compare (step S209). As a result, if it is determined that the processing for all the verbs extracted in step S203 has not been completed (N), the number of the verb to be processed is incremented by “1” (step S210), and a new one is added. The process proceeds to step S205 regarding the Vth verb.

  On the other hand, if it cannot be determined in step S205 that the V-th verb is an interesting word (N), the interest extraction unit 115 searches the interest dictionary 117 to determine whether the corresponding verb is registered ( Step S211). As a result, if the corresponding verb is registered in the interest dictionary 117 (Y), the process proceeds to step S206.

  FIG. 9 shows a part of the interest dictionary. The interest dictionary 117 stores interest words (verbs) registered by the user. The user can set the interest dictionary 117 for each person to be searched, or can set the interest dictionary 117 according to the age and sex of these persons.

  Returning to FIG. When the processing of all the verbs in the noun and verb set extracted in step S203 is completed (step S209: Y), a list of product information temporarily stored in step S208 is displayed on the search result presentation unit 118 (step S212). ), A series of processing ends (end). The user can select a product to be presented to Mr. A, for example, by looking at the result displayed on the search result presentation unit 118. If it is determined in step S211 that no corresponding verb is registered in the interest dictionary 117 (N), the process proceeds to step S209. Also, if it is determined in step S207 that the corresponding product information does not exist (N), the process proceeds to step S209.

  Next, a first example of the present invention that further embodies the above-described embodiment will be described.

Further, in FIG. 11, when the same processing as that in FIG. 8 is performed, the same step number is given, and description thereof will be omitted as appropriate.

  The main control unit 303 waits for reception of an e-mail (step S401). When an e-mail is received (Y), the main control unit 303 reads the address of the source of the e-mail received immediately before from the e-mail storage unit 313 in the content storage unit 114A and stores it in the telephone directory storage unit 314. It is determined whether or not the address is the e-mail address of the person registered in the telephone book (step S402). If it is an e-mail blue address of a person who is not registered in the telephone book (N), the search request process for the e-mail is terminated, and the process returns to step S401 again (return).

  If the address of the sender's e-mail is registered in the phone book (step S402: Y), the e-mail content received immediately before from the e-mail storage unit 313 is acquired (step S403). Then, this content is analyzed by grammar to extract all noun and verb sets (step S203).

  The reason for checking whether or not the sender of the e-mail is registered in the telephone directory is that when searching for a product showing the interest of a specific person, the specific person may be an acquaintance of the user of the mobile phone 100A. This is because there is a high possibility of being a partner who exchanges e-mails. The reason why the e-mail is selected as the content to be searched is that the e-mail is generally an important means for transmitting the sender's desire and likes and dislikes about various products.

  On the other hand, a mail from a sender who is not registered in the telephone directory is highly likely to be a spam mail from a person who has nothing to do with the user. There is no merit of obtaining information about a product by performing a search for such an e-mail transmission source. Moreover, it is troublesome for the user who receives the report to unnecessarily widen the search target of the mobile phone 100A and display the results one by one to the user.

  FIG. 12 shows a state in which a list of e-mail titles stored in the e-mail storage unit is displayed on the display of the mobile phone. Various kinds of received e-mail titles such as “about yesterday” are displayed on the display 316. Here, it is assumed that an e-mail titled “Christmas gift” indicated by an arrow 341 is received, and a set of nouns and verbs is extracted from the content.

  As an example, suppose that there is a sentence in the body of this e-mail saying “I want a reindeer plush toy for Christmas”. In this case, in the process of step S203, this sentence is first decomposed into “Christmas”, “Ni”, “Reindeer”, “No”, “Stuffed Toy”, “Ga”, “I want”. In this case, the nouns are “Christmas”, “Reindeer” and “Stuffed Toy”, and the verb is “I want”.

  As an example, the sentence analysis uses a corpus analysis. Corpus analysis uses text data such as written words collected in large quantities to reveal hidden features and language trends. In the sentences listed above, "reindeer plush" and "want" are extracted as a series of nouns and verb combinations, respectively. If there are other noun / verb combinations in the e-mail titled “Christmas Gifts”, these are extracted as other combinations as well.

  The processing from step S203 to step S212 is as shown in FIG. That is, the search request unit 113 initializes the parameter V for processing one verb at a time in the extracted noun and verb set to “1” (step S204). First, it is determined whether or not the first verb (V = 1) is a verb used when a person shows interest (step S205).

  In the case of a sentence “I want a reindeer plush toy for Christmas,” the verb “I want” is an interesting word (step S205: Y). Therefore, the product search unit 116 searches for products related to the nouns that are combined with this. If the interest extraction unit 115 cannot determine whether the verb “I want” is an interesting word, the contents of the interest dictionary 117 are referred to.

  In step S <b> 205, the interest extraction unit 115 may not make an independent determination on the interesting word, but may determine all of the verbs using the interest dictionary 117 as to whether it is an interesting word. When only the interest dictionary 117 discriminates the interesting words in this way, it is desirable to store typical interesting words as a basic dictionary in the interest dictionary 117 in advance. The user can enrich the interest dictionary 117 by registering interesting words such as dialects as a user dictionary.

  In the present embodiment, when it is determined that the verb “wanted” is an interesting word, product information is searched using the Internet 101 for “reindeer” and “stuffed toy” which are nouns in a set (step S206). ). When product information exists for these nouns (step S207: Y), the product information is stored in the temporary storage area of the storage medium described above (step S208).

  When searching for products, a general search site or product sales site on the existing Internet 101 may be used. Further, if necessary, it is possible to search a search site or a merchandise sales site provided by a communication carrier or a provider of the mobile phone 100A, or set these as a default search site. Of course, when a product is purchased from a site specially related to the mobile phone 100A, a score such as a discount or a point may be given to the user.

  FIG. 13 shows an example in which product information is displayed in step S212. In this example, the display 316 of the mobile phone 100A shown in FIG. 10 is divided into two upper and lower windows 351 and 352. In the upper window 351, sentences including an interesting word in the received e-mail are displayed together with their surrounding sentences.

  In the lower window 352, product information is displayed for each “noun”. In this example, product information such as “stuffed toy” and “reindeer” is displayed for each item. In general, the display area of the display 316 of the mobile phone 100A is not so large. Therefore, an overview of the product information is displayed in the lower window 352, and corresponding URLs may be embedded in the display areas of these product information. Thereby, the user can access a desired site on the web by selecting a corresponding item, and can display detailed product information on the entire surface of the display 316, for example.

  In the example shown in FIG. 13, “nouns” are divided into a superordinate concept “stuffed toy” and a subordinate concept “reindeer stuffed toy”. As a result, when the user selects the product, the product information specialized for “reindeer stuffed toy” is displayed, and the product information can be collected for “stuffed toy” other than “reindeer”. The range of choice is expanded.

  According to the first embodiment described above, an e-mail can be analyzed to extract a product name expected to be obtained by a terminal user who has transmitted the e-mail. Therefore, not only when giving a gift to a person by searching for a site containing product information or a product sales site and presenting it to that person, but also when recommending a product to that person You can recommend products that suit your needs.

  In the first embodiment, the product information is searched on the condition that the address of the sender's e-mail is registered in a communication terminal such as a mobile phone. For this reason, it is possible to exclude e-mails coming from persons who are not registered in the telephone book of the communication terminal of the e-mail recipient, such as spam mail senders, from the search target of the product.

  Further, since the communication unit searches for product information using the Internet, it is possible to present the purchase destinations and services of products to users over a wide range of stores on the website.

  Note that in the first embodiment described above, product information is searched for using e-mail as content, but the content target is not limited to e-mail. You may search the merchandise information regarding the goods which a specific person is interested using other contents like ToDo (ToDo) and a schedule.

  <Modification of the first embodiment>

  In the first embodiment described above, product information is searched from received contents such as individual e-mails. For this reason, only product information relating to one product may be displayed on the display 316 (FIG. 10), or specific product information may not be analyzed. It is good if the user also remembers the received contents of past e-mails about the person who sent the e-mail, but if that is not the case, there is a possibility of making a ubiquitous evaluation of the products showing the person's interest . In addition, the received e-mail does not include an interesting word, and there are cases in which a product indicating the interest of the person cannot be specified only by the contents of one e-mail.

  In the modification of the first embodiment, in such a case, the user can acquire the product information by referring to the content of the same person in the past adjusted in the content storage unit 114A shown in FIG. Here, in order to simplify the description, a case where the user refers to past e-mails of the same person will be described. A set of interesting words and nouns of the same person may be extracted from other past contents such as ToDo and schedule.

  FIG. 14 shows the flow of additional search processing for product information in this modification. This will be described with reference to FIGS. 10 and 11. Moreover, the same step number is attached | subjected to the part which performs the same process as FIG. 8, These description is abbreviate | omitted suitably.

  In this modification, first, as described with reference to FIG. 11, when an e-mail is received from a person registered in the telephone directory, the product information search result is displayed on the display 316 (step S212A). At this time, the display 316 displays a choice of whether to end the process as it is (step S411) or whether to execute a search for detailed product information about the same person (step S412).

  It is assumed that the user selects to end the search process as it is (step S411: Y). In this case, the search process ends (end) as described in FIG.

  Next, a case where the user selects execution of detailed product information search will be described. In this case (step S411: N, step S412: Y), the search request unit 113 acquires the content of the past e-mail about the transmission source of the e-mail acquired in step S403 of FIG. 11 from the e-mail storage unit 313 ( Step S413). At this time, the user of the mobile phone 100A can make a setting to limit the period of the e-mail acquired in advance.

  When the search request unit 113 acquires the same person's past e-mail, the search request unit 113 extracts a set of nouns and verbs from these contents (step S203A). Thereafter, the processing from step S204 to step S212 is performed, the result is displayed on the display 316, and the processing is terminated (END). In the display in step S212, product information related to the past may be displayed in the lower portion of the display area of the display 316, or vice versa. Further, the frequency of appearance of nouns of the same product may be calculated, and product information may be displayed in order of frequency. In addition, weights indicating the degree of interest are attached to the interest words, and the total interest level is calculated for each product in relation to the appearance frequency of the product nouns, and the product information is displayed in the order and information amount according to this. It is also effective to do.

  Next, a second embodiment of the present invention will be described.

  FIG. 15 shows a state in which a mobile phone as an information processing apparatus in the second embodiment of the present invention is connected to the Internet. In FIG. 15, the same parts as those in FIG. 7 or 10 are denoted by the same reference numerals, and description thereof will be omitted as appropriate.

  The mobile phone 100B of the second embodiment has a main control unit 303B having a CPU 301 and a memory 302B. The CPU 301 controls each unit of the mobile phone 100B by executing a control program stored in the memory 302B. Further, at least some of these units can be realized by software.

  The search request input unit 112B includes two touch panels, a first touch panel 511 and a second touch panel 512. Similarly, the search result presentation unit 118B includes two liquid crystal displays, a first liquid crystal display 513 and a second liquid crystal display 514. Actually, the first touch panel 511 is attached to the surface of the first liquid crystal display 513, and the second touch panel 512 is attached to the surface of the second liquid crystal display 514. Instead of the first liquid crystal display 513 and the second liquid crystal display 514, another display such as an organic EL display may be used.

  The search request unit 113B has a new function of inputting coordinate data corresponding to coordinates touched from the first touch panel 511 and the second touch panel 512, respectively. The rest is the same as the search request unit 113 in FIG. The product search unit 116B has a new function of sending different display data to the first liquid crystal display 513 and the second liquid crystal display 514, respectively. The rest is the same as the product search unit 116 in FIG.

  The mobile phone 100B in the second embodiment is a foldable phone. In the cellular phone 100B, a first liquid crystal display 513 is disposed on a surface on which a display is disposed in a normal foldable telephone, and a first touch panel 511 is attached to the surface. In addition, a second liquid crystal display 514 is disposed on a surface on which an operation panel is disposed in a normal foldable telephone, and a second touch panel 512 is attached to the surface. Therefore, for example, icons and a software keyboard can be displayed on the second liquid crystal display 514 and the user can operate them using the second touch panel 512. For this reason, a conventional operation panel having a large number of key switches is unnecessary.

  FIG. 16 shows a display state before searching when the folding cellular phone is opened in the second embodiment. In FIG. 16, for the sake of simplification, detailed portions such as a hinge mechanism of the mobile phone 100B (FIG. 15) are not shown. This will be described with reference to FIG.

  The foldable mobile phone 100B has a structure in which a first housing 521 and a second housing 522 are arranged to be freely opened and closed by a hinge mechanism (not shown). A first liquid crystal display 513 is disposed in the first housing 521, and a first touch panel 511 is attached to the surface thereof. A second liquid crystal display 514 is disposed in the second housing 522, and a second touch panel 512 is attached to the surface thereof. The user usually holds the second housing 522 with his hand and mainly operates the first touch panel 511 with the fingers of the opposite hand.

  When the user opens the mobile phone 100B and sets the mode for displaying information related to e-mail, a list of recently received e-mails is displayed on the first liquid crystal display 513. Assume that the user selects the title “Christmas gift” indicated by the arrow 541 using the first touch panel 511. Then, the second liquid crystal display 514 displays that the e-mail is sent from Mr. A and that Mr. A is registered in the phone book stored in the phone book storage unit 314. The Therefore, the user can know that the e-mail titled “Christmas gift” is not a junk mail. On the second liquid crystal display 514, it is also possible to display other attributes such as the photograph together with the name of Mr. A, or display it instead of the name.

  FIG. 17 shows an example of a display state of a foldable mobile phone in a state where an e-mail sent from a transmission source registered in the telephone directory is opened. This will be described with reference to FIG.

  When the user selects an e-mail titled “Christmas gift” shown in FIG. 16, the text is displayed on the first liquid crystal display 513. At this time, the interest extraction unit 115 discriminates the verb “wanted” as an interesting word and extracts nouns such as “reindeer” and “stuffed toy” as a set. Then, the product search unit 116B searches the Internet 101 for related information of these nouns.

  As a result, the second liquid crystal display 514 displays the product information related to the noun that is a set of interesting words such as “reindeer” and “stuffed toy”. Therefore, the user can give a present to Mr. A with reference to the product information, or write an e-mail for giving advice on the product to Mr. A and reply.

  In the above description, the product information is searched and displayed based on the email received by the user, but the set of interesting words and nouns is extracted from the content itself such as the email created by the user. This may be displayed. In this case, it is possible to create a sentence such as “There is a wonderful reindeer stuffed toy at the B store” or content such as an e-mail incorporating the URL of the B store.

  According to the second embodiment described above, two displays are arranged using a foldable mobile phone, and different information is displayed on them. As a result, while displaying information that should be originally displayed such as the contents of e-mail received on one display, information of different intentions such as product search results is simultaneously and physically separated on the other display. Can be displayed.

  In the second embodiment, the first and second touch panels 511 and 512 are arranged in the search request input unit 112B. However, the number of these touch panels is arbitrary, and may be one or three or more. Similarly, in the second embodiment, the first and second liquid crystal displays 513 and 514 are arranged in the search result presentation unit 118B, but the number of these displays is arbitrary and may be one or three or more. . In addition, it is not necessary to display information about e-mails or products on the first and second liquid crystal displays 513 and 514 at the same time. For example, it is possible to switch the display of one display and display some information alternately. is there.

  In the second embodiment, the present invention is applied to the mobile phone as in the first embodiment. However, the present invention is not limited to this. The present invention can be similarly applied to other information processing apparatuses such as PHS, PDA (Personal Digital Assistant) or a small and portable personal computer. In addition, the content is expressed in text, and naturally includes various types of content that express the actions, thoughts, and feelings of the person who wrote the content.

  Further, in the embodiment and each example and modification described above, the interest in the product has been described, but the present invention is not limited to this. For example, information on services and events in the natural world can be easily acquired by using the present invention. In addition, it is not always necessary to acquire information on products or the like that are of interest through a communication network such as the Internet, but it is acquired by searching from a dedicated information database connected to the information processing device.
