Description

  The present invention relates to a taxonomy display device, a taxonomy display method, and a taxonomy display program for classifying a plurality of electronic documents into a plurality of categories from various perspectives and presenting them to a user.

  Conventionally, a plurality of electronic documents are classified into categories consisting only of documents that meet certain conditions. For example, a plurality of files each containing the entire text of the published patent gazette are classified into one of the categories “Hokkaido”, “Tohoku”, and “Kyushu Okinawa” for each address of the applicant. In this way, by defining categories and classifying documents, it is possible to easily find a target document from a large number of documents.

  A single document is not necessarily classified into only one category. For example, in the case of a patent relating to a joint application between a company in Hokkaido and a company in Aomori Prefecture, the publication file can be classified into either the “Hokkaido” category or the “Tohoku” category. That is, in this case, the document and the category have a many-to-many correspondence. Many of the conventional techniques allow a document to be classified into a plurality of categories.

  However, in this case, there is a problem that it is difficult to understand how many documents classified into a certain category are also classified in other categories.

  For example, as shown in FIG. 1, when a plurality of documents 1 to 8 are classified into a plurality of categories A to D in a many-to-many relationship, the document names and the number of documents in each category are as shown in FIG. Although the list may be displayed, the total number of documents classified into category A and category B is unknown from this table. For example, as shown in FIG. 3, if the document name and the number of documents are displayed for each category and every combination of categories, it becomes difficult to find a target portion as the number of categories increases, and the classification status Depending on the case, the number of items with 0 documents increases and the screen area is wasted.

  In order to solve the above-described problems caused by the prior art, the present invention reduces the number of documents that are classified redundantly between categories when a plurality of documents are classified into a plurality of categories in a many-to-many relationship.

  DESCRIPTION OF EMBODIMENTS Preferred embodiments of a taxonomy display device, a taxonomy display method, and a taxonomy display program according to the present invention will be described in detail below with reference to the accompanying drawings, but before that, the outline of the present invention will be briefly described. To do.

(Outline of the invention)
In the present invention, the document classification status as shown in FIG. 1 is displayed in the format as shown in FIG. 4 or 5 instead of the table format as shown in FIG. In FIG. 4, the total number of documents classified into individual categories is displayed in a document number display area 400 in the format “number of documents in category / total number of documents”. For example, in the case of category A, it can be seen that three out of eight documents in total are classified into this category.

  If no category is selected in the document number display area 400, the document list display area 401 below it is blank. For example, if the check box 400a for category A is checked, as shown in FIG. In addition, the titles and URLs of three documents in category A (specifically, document 1, document 2, and document 3) are displayed in the document list display area 401.

  At this time, the numerical value displayed for each category in the document number display area 400 is “the number of documents classified into the selected category among the documents in the category / the number of documents in the category”. That is, for example, “1/3” of category B indicates that among the three documents classified into category B among all documents, there is one document that is also classified redundantly in category A. Note that the category A is “3/3”, and thus the values before and after “/” are always equal in the selected category.

  The screen in FIG. 5 is an example in which the category A is selected in FIG. 4, but the screen when the category B is selected is as shown in FIG. As in FIG. 5, the document number display area 400 displays the number of documents classified into the selected category among the documents of each category. For example, among the three documents of category A, the document number is also classified into category B. It can be seen that there is only one document. In the document list display area 401, the titles and URLs of the three documents (specifically, document 3, document 4, and document 5) in the selected category B are displayed.

  Thus, in the present invention, for example, when category A is selected as shown in FIG. 5, the number of documents “A∩A”, “A∩B”, “A∩C”, and “A∩D” is selected. The number of documents “∩A”, “B∩B”, “B∩C”, and “B∩D” is displayed together with the number of documents in categories A to D, respectively. The user can easily grasp how many documents in the category of interest are classified into other categories.

  In addition, the function that can systematize information virtually by defining classification conditions, including the functions realized by the present invention, and present one piece of information to the user in various ways and in various ways. People collectively refer to “taxonomy function”. Taxonomy generally refers to “taxonomy”, but in this technical field it means “information classification system”, and tracing this makes it easier to access the target information and the relationship between the information. It is also possible to understand sex.

  Next, FIG. 8 is an explanatory view functionally showing the configuration of the taxonomy display device according to the embodiment of the present invention. In the figure, reference numeral 800 denotes a document information storage unit, which is a functional unit that holds document information of a plurality of documents to be classified by the apparatus. Here, the “document information” is, for example, a unique ID for each document, vocabulary or title in the text, attribute information such as URL or creation date / time, and the like. In addition, each of the documents to be classified is a file in which the entire text of the published patent gazette is stored one by one, and its main body is held in a database on the network (“published patent DB” in the figure) Of course, it may be held in the apparatus.

  A document classification unit 801 is a storage unit that classifies the document with reference to document information in the document information storage unit 800 and a classification system file in a classification system storage unit 806 described later. As will be described later, the “classification system file” is an XML file that defines a group relationship among a plurality of categories, classification conditions for each category (conditions that a document classified into each category should satisfy), and the like. When one document meets the classification conditions of a plurality of categories, the document classification unit 801 sets all the categories as the classification destination of the document.

  Reference numeral 802 denotes a classification result storage unit, which is a functional unit that holds the classification result obtained by the document classification unit 801. Although the data structure of the classification result is arbitrary, it is assumed here to be a table format as shown in FIG. 9, for example.

  As will be described later, in the present invention, a plurality of “categories” (“elements” in the applicant's terminology) are grouped under a superordinate concept of “viewpoint” (the same “axis”). For example, in the case of a published patent gazette, categories such as “Hokkaido”, “Tohoku”, “Kyushu Okinawa” are classified as “industry” (applicant's industry) from the viewpoint of “region” (address of applicant). From this viewpoint, there are categories such as “manufacturing”, “service”,... Even a category with the same name is treated as a different category if the upper viewpoint is different. In the table shown in the figure, as many column items as the number of different categories are prepared, and for each document that is a line item, “◯” is set as the category (may be plural) of the classification destination. In actual data, 1 (bit) is set only at a circled portion.

  Returning to the description of FIG. 8, reference numeral 803 denotes a UI (user interface) screen display unit that displays various screens described later on the display 710, and in response to input to the screen, a document search unit 804 described later or This is a functional unit that instructs the classification system setting unit 805 or the like to perform necessary processing. As shown in the figure, the UI screen display unit 803 includes a document number counting unit 803a. Reference numeral 804 denotes a document search unit, which is a functional unit that reads document information of a document instructed from the UI screen display unit 803 from the document information storage unit 800 and reads the main body of the document from an external database.

  FIG. 10 is an explanatory diagram illustrating an example of a main screen displayed by the UI screen display unit 803. On the main screen, a plurality of categories are classified and displayed for each viewpoint according to a classification system file in a classification system storage unit 806 described later. The total number of documents of each category counted by the document number counting unit 803a is shown to the right of each category name. For example, in the case of the “Hokkaido” category from the “region” viewpoint (hereinafter referred to as “the“ region-Hokkaido ”category”), 159 documents are classified into the category.

  Then, when the user selects, for example, the “Region-Tohoku” category on the screen shown in the figure (the checkbox of the “Region-Tohoku” category is checked), the UI screen display unit 803 that receives this selects the number of documents. The unit 803a refers to the classification result storage unit 802 to calculate the number of documents for the combination of the selected category and all other categories.

  That is, in the example of FIG. 10, "region-Tohoku region-Hokkaido" "region-Tohoku region-Kanto" "region-Tohoku region-Chubu Tokai" ... "region-Tohoku region type-manufacturing" ... The number of documents included in 14 combinations of “region-Tohoku genre-others” is obtained. For example, the number of documents classified into “Region-Tohoku” and “Region-Hokkaido” is n bit strings in which only the first and second bits are 1 and all subsequent bits are 0 (n is a classification). The number of column items in the result table is created, the logical product with each record in FIG. 9 is calculated, and the number of records whose result is the same as the bit string is counted.

  Further, in parallel with the above, the UI screen display unit 803 reads the ID of the document classified into the selected “Region-Tohoku” category from the classification result table of FIG. 9, and the document information of the document specified by the ID Is returned to the document search unit 804. In response to this, the document search unit 804 searches the document information storage unit 800 with the ID, and acquires document information (for example, a title, URL, etc.) of each document.

  After that, the UI screen display unit 803 displays the number of documents obtained by the document number counting unit 803a and the document information returned from the document search unit 804 as shown in FIG. In the figure, the numerical value on the right side of each category means “the number of documents classified into the selected category among the documents in the category / the number of documents in the category”, for example, in the “region-Hokkaido” category. If there are, out of 159 documents classified into the category, five are also classified into the selected “Region-Tohoku” category. In addition, 80 documents are classified into both the “region-Tohoku” category and the “business category-manufacturing” category.

  Returning to the description of FIG. 8, a classification system setting unit 805 is a “classification system file”, that is, a group relationship of a plurality of categories and a classification condition for each category, according to the setting content input from the UI screen display unit 803. This is a functional unit that creates and edits an XML file that defines the above. A classification system storage unit 806 is a functional unit that holds the classification system file created and edited by the classification system setting unit 805.

  When one of the viewpoint names shown in the screens of FIGS. 10 and 11, for example, “region” is clicked, the UI screen display unit 803 displays a classification system setting screen as shown in FIG. 12. In the screen shown in the figure, the category names already defined under "Region" ("Hokkaido", "Tohoku" ... "Kyushu Okinawa") and the conditions that should be satisfied by the documents classified in each category (classification) Condition) is displayed in a list, and the existing classification system can be modified by editing the list. It is also possible to delete existing categories. A new category input field 1200 is provided at the bottom, and a category can be added to the above viewpoint by setting an arbitrary name and classification condition.

  In the figure, “query” is a vocabulary that should appear in the text of a document. In addition, the “constraint condition” in the figure is a condition that satisfies the attribute of the document. For example, only documents whose creation date and time is after 2004 can be classified into the category. Here, only “query” and “constraint condition” are listed as classification conditions. However, when a classification method based on, for example, the vector space method is adopted in the document classification unit 801, the lowest score to be achieved by the document. You may be able to define it together with the ranking.

  When a new viewpoint is to be added to the classification system, for example, the viewpoint addition button 1000 is clicked on the screen of FIG. 10 or FIG. Also in this case, the UI screen display unit 803 displays a classification system setting screen as shown in FIG. 12 (in this case, all input items are blank).

  Next, FIG. 13 is a flowchart showing the procedure of taxonomy display processing in the taxonomy display device according to the embodiment of the present invention. Prior to the start of the illustrated process, it is assumed that a classification system that is a basis for classification is already set in the classification system storage unit 806.

  When there is a document classification instruction from the user (step S1301: Yes), the apparatus first refers to the document information in the document information storage unit 800 by the document classification unit 801, and is a category to which individual documents are classified. Is determined (step S1302). Then, a classification result table as shown in FIG. 9 is generated and stored in the classification result storage unit 802 (step S1303).

  Next, in order to display the main screen as shown in FIG. 10, the UI screen display unit 803 first counts the number of documents classified into each category by the document number counting unit 803a (step S1304). Then, the main screen as shown in FIG. 10 is displayed by associating each category with the number of documents included therein (step S1305).

  Next, when the user selects one of the categories on the screen shown in the figure (step S1306: Yes), the UI screen display unit 803 is the document number counting unit 803a and overlaps with the category selected above for all categories. The number of documents classified as follows is counted (step S1307). In addition, the document ID in the selected category is output to the document search unit 804, and the document information of the document specified by the ID, specifically, the title and URL are read (step S1308). Then, using the number of documents recalculated by the document number counting unit 803a and the document information read by the document search unit 804, the screen in FIG. 10 is re-displayed as shown in FIG. 11 (step S1309).

  Further, when the user instructs the setting of the classification system on the screen of FIG. 10 or FIG. 11, specifically, when any viewpoint name or viewpoint addition button 1000 is clicked (step S1306: No, step S1310: Yes), the UI The screen display unit 803 displays the classification system setting screen as shown in FIG. 12 (step S1311), and outputs the setting contents on the screen to the classification system setting unit 805. In response to this, the classification system setting unit 805 updates the classification system file in the classification system storage unit 806 according to the above contents (step S1312). Thereafter, the document is reclassified and the number of documents is recalculated according to the updated classification system, and the main screen is displayed again (steps S1302 to S1305).

  In this case, the process immediately proceeds from step S1312, to step S1302. However, after the classification system is updated, the reclassification and the recalculation of the number of documents may be performed again after waiting for an instruction from the user (classification). Just because the system has been updated does not necessarily mean that the classification has to be redone immediately).

  When the user instructs display of a document in the document list on the screen of FIG. 10 or FIG. 11, specifically, when the URL is clicked (step S1306: No, step S1310: No, step S1313: Yes), the UI In response to the instruction from the screen display unit 803, the document search unit 804 acquires the main body of the document specified by the URL (step S1314). Then, the UI screen display unit 803 opens a window different from the main screen and displays the text of the document (step S1315).

  Thereafter, the processing from step S1306 is repeated until the end is instructed (step S1306: No, step S1310: No, step S1313: No, step S1316: No), and when the user instructs the end from the menu or the like (step (S1316: Yes), the screen being displayed on the UI screen display unit 803 is deleted (step S1317), and the process ends.

  According to the embodiment described above, in a situation where a plurality of documents are classified into a plurality of categories, it is possible to easily grasp how many documents are classified into the category of interest in other categories. it can. For example, in the example of FIG. 11, there are 5 patent applications related to a joint application between an applicant in the Hokkaido region and an applicant in the Tohoku region, and there are 80 applications related to the manufacturing industry from applications in the Tohoku region. I understand. And, for example, by estimating the strength of the relationship between categories based on the number of overlapping documents, which industry is the driving force for technological innovation in each region, and whether there are local features in the first place, It can be the basis for advanced and intelligent analysis.

  Note that the example of FIG. 11 described above is an example in which only one category is selected, but it is also possible to select a plurality of categories at the same time, as can be understood from the selection by checking the check box. A plurality of categories can be selected from the same viewpoint, or a plurality of categories can be selected across a plurality of viewpoints. For example, when “Industry-Manufacturing” is selected together with “Region-Tohoku” in FIG. 11, “Region-Hokkaido Sakai Area-Tohoku Sakai Industry-Number of Documents / Region-Hokkaido” "Number of documents" will be displayed.

  In the above-described embodiment, for example, when category A is selected, the number of documents is obtained for “A」 B ”,“ A∩C ”,“ A∩D ”, etc., but instead“ A∪B ”“ A ” The number of documents may be obtained for “C”, “A∪D”, and the like. This is obtained, for example, by counting the number of records in which the bit string after the calculation is not all 0 in the bit calculation with each record in FIG.

  In the above-described embodiment, when a category is selected, only the number of documents is recalculated / redisplayed for other categories. For example, a category with a large number of recalculated documents (the selected category and more The display order of the categories may be changed so that the category sharing the document) is higher and the lower category is lower.

  In the embodiment described above, since the published patent publication is exclusively classified, the viewpoint and category are as shown in FIG. 10 and FIG. 11, but if the nature of the target document is different, the classification system is naturally. Will also be different. Therefore, only the classification system specific to the database being selected may be displayed on the main screen of FIG. 10 or FIG. 11 (so when the target database is switched, the classification system below it is also switched at the same time. The viewpoints and categories defined for each of the databases that can be selected) may be displayed on one screen without particular distinction so that they can be shared among the databases. FIG. 14 is an example of the former. When the target database is “sales report”, for example, it is understood that the viewpoint and category on the screen are also for the database.

  In the screen of FIG. 14, “the number of documents classified in the selected category among the documents in the category / the number of documents in the category” is numerically displayed, and a bar graph indicating the ratio between the two is also displayed. Yes. For example, in the figure, the “Charger-A Yamaichiro” category bar graph 1400 has a total length of 107 (the number of documents in the “Person-A Yamaichiro” category), and the length of the dark portion of the total. Corresponds to 27 (the number of documents that are also classified in the “content-suggestion” category being selected among the documents in the person in charge-A Yamaichiro category). As described above, the number of documents that are also classified into the selected category changes depending on which category is selected, so the ratio of the length of the dark color part to the total length of the graph changes dynamically. (On the other hand, the length of the entire graph is constant regardless of the category selection status).

  The graph is not limited to the bar graph as shown in the figure, and may be anything. In addition, both the numerical display and the graph display are not necessary, and of course, only one of them may be used. By displaying the graph as shown in FIG. 14, it is possible to more intuitively present to the user how many documents in a certain category are also classified in the selected category. The user usually selects a category that has a high ratio of documents in common with the selected category, that is, a category that is strongly suggested to be related to the selected category. There is an effect that the category to be selected can be easily recommended to the user.

  In the screen of FIG. 14, the currently selected “content-suggestion” category column is highlighted (specifically, the background color is different from the other columns, the shaded display is used) Etc.).

  In addition, the categories that do not have any documents in common with the currently selected category, in the example shown in the figure, the fields of the “Domestic Region-Hokkaido” category and the “Domestic Region-Kyushu Okinawa” category are grayed out and cannot be selected in this state. However, when at least one of the selected categories is in a non-selected state (selection is canceled) and the number of common documents is no longer 0, it can be selected and the display form returns to the normal display. However, since the “domestic region-Hokkaido” category does not have a document common to any category (there is no document classified into the category in the first place), it remains grayed out regardless of which category is selected. It should be noted that the category itself may be selected by simply changing the display form from the normal display (for example, displaying it in light color) instead of graying out.

  The taxonomy display method described in this embodiment can be realized by executing a program prepared in advance on a computer such as a personal computer or a workstation. This program is recorded on a computer-readable recording medium such as HD, FD, CD-ROM, CD-RW, MO, and DVD, and is executed by being read from the recording medium by the computer. The program may be a transmission medium that can be distributed via a network such as the Internet.

  As described above, the taxonomy display device, the taxonomy display method, and the taxonomy display program according to the present invention are useful for multifaceted browsing of the classification status of electronic documents organized under a certain classification system. In particular, this is suitable when a plurality of documents are classified into a plurality of categories in a many-to-many relationship, and it is difficult to intuitively understand the entire classification status.
