Description

The present invention relates to a document processing device and a classification grant support system.

It is common practice to display multiple document data on a computer screen and compare the contents of these documents. In such document comparison work, it is possible to visually check where the contents of a plurality of documents to be compared match, and to highlight different parts using software. ing.

Conventionally, a document management system having an interface for improving the readability of document data and shortening the grasping work time for comparing a plurality of document data has been proposed (see Patent Document 1). In the document management system of Patent Document 1, two patent documents are displayed on the display device at the same time, and the area of the other patent document in which the contents similar to the description contents of one patent document are described is highlighted on the display device. This makes it possible to visually grasp the degree of relevance between patent documents.

Further, as an example of the work of comparing a plurality of document data, there is known a classification giving work in which a document to be classified and a document in which the classification is described are compared and given a classification, and such a classification giving work is performed. A device for assisting or automating has been proposed (see Patent Document 2 and Patent Document 3). In the classification granting support device of Patent Document 2, a document to be classified and a document in which a classification such as F-term is described are input, a word of one of the input documents is extracted, and the extracted word is used as the other. If the word is found in the other document, the word is highlighted in both documents. Further, the document analysis device of Patent Document 3 uses estimation dictionary data in which the search condition is described by a literary expression including a basic element in each range divided by a predetermined range in which the document is separated as a semantic expression. , The degree of similarity between the estimation dictionary data and the bibliographic term data is expressed by a score so that the degree of satisfaction of the search conditions can be recognized.

When the classification is given by comparing the document to which the classification is given and the document in which the classification is described, only the comparison between the divided area units of the documents or the comparison between the patent document and the F-term table as a whole is performed as in the prior art. Instead, there is a need to make an easy-to-understand comparison of how many terms associated with each classification are related to patent documents. Further, when comparing the patent classification table and the patent document, not only the two are displayed side by side as in the prior art, but also a plurality of term groups or patent documents associated with the classification are displayed side by side on the screen. There is a need for a user interface that can be compared.

In addition, in order to perform highly accurate classification assignment using computer-based automatic classification assignment technology, it is necessary to enhance the classification assignment dictionary that associates patent classification with related technical terms. However, among the classifications defined in the patent classification, most of the classifications have a small number of patent documents granted, and it is difficult to learn the classification grant dictionary even if machine learning is used, so classification by computer is used. It is in a situation where it is not possible to achieve the same level of accuracy as people with automatic granting alone. Therefore, in order to grant a high-quality patent classification, it is necessary to manually assign a classification symbol to the patent document while using the automatic grant by a computer as an auxiliary. When the classification symbol is manually assigned in this way, there is a need for a support system that can quickly find the description part (classification grant basis part) related to the classification defined in the patent classification table in the patent document. There is.

The present invention has been made in view of the above circumstances, and is a document in which a plurality of term groups or a plurality of documents can be displayed in a list on a display screen, and the relationship between these term groups and a document can be easily grasped. It is an object of the present invention to provide a processing apparatus. Furthermore, it is a further object of the present invention to provide a classification granting support system that supports high quality classification granting using the document processing apparatus.

The document processing apparatus of the first aspect of the present invention is a term spectrum that displays a spectrum based on a document display means for selectively displaying a plurality of documents and a term group data set including a plurality of term groups consisting of one or a plurality of terms. A term that is a display means and in which, when a term of the term group is included in the document, the term spectrum bar string indicating the position of the term in the document by a spectrum bar of the color set for the term is arranged. The term spectrum display means for displaying the group box side by side for each of a plurality of term groups is provided, and when the user selects a specific term group box, the document display means is the selected term group box. The term in the document corresponding to the spectrum bar included in the term spectrum bar column is configured to be highlighted in the color set for the term.

The classification granting support system of the second aspect of the present invention includes the document processing apparatus of the first aspect and the classification granting means for assigning a classification to the document, and the plurality of term groups correspond to a plurality of classifications. It is characterized by being.

In the document processing apparatus or classification granting support system of the third aspect of the present invention, the terms included in the term group constitute a literary expression consisting of a seed term and a co-occurrence term, and the term spectrum display means is used. , The term spectrum bar column of the term group box is characterized in that the spectrum bar is displayed only at the position in the document where the combination of the species term and the co-occurrence term corresponding to the literary expression exists.

The document processing apparatus according to the fourth aspect of the present invention is a document display means for selectively displaying a plurality of documents and a term spectrum display means for displaying a spectrum based on one or a plurality of terms set by a user. When a term is included in the document, a document box in which a term spectrum bar string indicating a position in the document of the term is arranged by a spectrum bar of a color set together with the term is displayed side by side for each of the plurality of documents. If the user selects a particular document box, the document display means displays the document corresponding to the selected document box and is included in the term spectrum bar column. It is characterized in that the term in the document corresponding to the spectrum bar is highlighted in the color set for the term.

Further, the term group display means 13 has a file input / output function with the term group database 50 and an export function to the term spectrum display means 12.

The term group creating means 14 mechanically generates terms necessary for creating a new term group constituting the term group data set.

FIG. 2 is a diagram showing an example of a document display screen 100 displayed by the document processing apparatus 10 of the first embodiment. Here, an example of the document display screen 100 displayed by the document display means 11 is shown schematically.

A patent document is displayed on the document display screen 100 shown in FIG. 2 as an example of a document. The document display screen 100 has a "reference number list" column (A), a "term panel" column (B), a "paragraph structure" column (C), a "specification text" column (D), and a "spectrum bar" column ( It has a layout including E), a "code list" column (F), and a "drawing" column (G). In addition, the layout is not limited to such a layout, and other layouts may be adopted.

The "reference number list" column (A) is a column for displaying the patent document number input by the user. When the document display means 11 detects that the document number displayed here is selected by clicking or the like, the document display means highlights the document number and acquires the patent document corresponding to the document number from the document database 40. It is displayed on the document display screen 100 in a predetermined layout.

The "term panel" column (B) is a column for displaying search keywords for searching the displayed patent document together with color information. In the example of FIG. 2, "clothes, clothes ... apron" is displayed with a red background color, "hands, neck ... shin" is displayed with a gray background color, and "work clothes, water ..." "Fishing" is displayed with a blue background color.

The user searches using the color execution, uncoloring, clearing all terms, clearing all colors command buttons, and the color table of colors 1 to 32 displayed in the "term panel" column (B). Color information such as text color and background color can be set for each keyword or search keyword group. The search keyword or color information to be set may be manually input by the user, or may be imported from the multi-term panel 300 as described later.

The "paragraph structure" column (C) is a column for displaying paragraph headings, paragraph marks, etc. included in the selected document. In the case of patent documents, in the "paragraph structure" column (C), major headings such as [biological matters], [summary], [claims], [detailed description of the invention], and [claims] , [Technical field], [Background technology], and other subheadings are displayed.

The "specification text" column (D) is a column for displaying the scope of claims and the contents of the specification described in the patent document as text. If the specification text does not fit in the "specification text" column (D), scroll display is performed. In the specification text being displayed, the term corresponding to the search keyword set in the "term panel" column (B) is highlighted with the set color information. In the example of FIG. 2, for example, "clothes" are displayed with a red background color, and "hands" are displayed with a gray background color. The synonym dictionary may be referred to from the search keyword set in the "term panel" column (B), and the synonym of the set search keyword may be highlighted as the same search keyword. In this case, it is assumed that the synonym dictionary is stored in the document processing apparatus 10 in advance.

The “spectrum bar” column (E) is a column for displaying a list of spectrum bars indicating positions in the specification text of terms corresponding to the search keyword. In the example of FIG. 2, six columns of spectrum bars are displayed. For example, in the first spectrum bar column, the term corresponding to the search keyword "clothes, clothes ... apron" is contained in the specification text. The position that appears in is displayed as a red bar, and the position in the specification text of the term corresponding to the search keyword "hand, neck ... shin" is displayed as a gray bar in the second spectrum bar column. ing.

The spectrum bar is displayed with the background color of the corresponding search keyword, but if the same background color is set for multiple search keywords, these multiple search keywords are treated as one group and the spectrum bar of the same color is displayed. Displayed as a column. The spectrum bar column may be hidden for a group of search keywords that do not appear in the document.

By scrolling the specification text while looking at the spectrum bar, the user can easily move the display content to the position in the specification text where the search keyword exists. Also, by clicking on one of the spectrum bars, the display content can be jumped to the corresponding position in the specification text.

The "code list" column (F) is a column for displaying the reference reference numerals attached to the figures and their explanations. Further, the “figure” column (G) is a column for reducing, arranging, and displaying the drawings included in the patent document.

FIG. 3 is a diagram showing an example of a multispectral screen 200 displayed by the document processing apparatus 10 of the first embodiment.

When the term spectrum display means 12 detects the display instruction of the multi-spectrum screen 200 by the user and receives the information specifying the term group data set, the term spectrum display means 12 acquires the instructed term group data set from the term group database 50 and is based on the instructed term group data set. To generate a multispectral screen 200. Then, the generated multispectral screen 200 is superimposed and displayed on a part of the document display screen 100. In the multispectral screen 200, a plurality of term group boxes 210 corresponding to each term group of the term group data set are provided, and in each term group box 210, the name of the term group (in FIG. 3, " Along with "AA00", "AA10", etc.), the term list 211 and the term spectrum bar column 212 are displayed according to preset color information.

One term group data set is composed of a plurality of term groups, each of which is associated with some meaning, and each term included in the term group is set with color information for displaying the term. As the color information, the text color and the background color of the text can be set, and the color selection (either the text color or the text background color) of the spectrum bar when the term is displayed in the spectrum and the term spectrum bar. You can also choose the background color of the column (either black or white). In addition to the color information, each term may be associated with character attributes such as font, size, and character decoration.

As an example of the term group data set, FIG. 3 illustrates a plurality of term groups associated with each classification of the F-term theme 3B011 (professional, industrial, or sports protective clothing). When the term spectrum display means 12 receives the theme symbol "3B011" as information for identifying the term group data set from the user, the term group data set corresponding to the theme symbol "3B011" is acquired from the term group database 50, and this term is used. A term group box 210 for each term group associated with a plurality of classifications included in the group data set is displayed in the multispectral screen 200. For example, in the term group box 210 associated with the classification AA00, in the term list 211, the group of terms "clothes, clothes ... apron" is displayed with a red background color, and "hands, necks ... shins". A group of terms (not shown) is displayed with a gray background. Note that synonyms of terms included in the term group may be automatically included in the term group having the same background color. Further, among the terms included in the term group, the terms that do not exist in the document may be hidden in the term group list 211.

Next, the term spectrum display means 12 displays the term spectrum bar column 212 in each term group box 210. A plurality of term spectrum bar rows 212 can be displayed in one term group box 210, and one term spectrum bar row 212 corresponds to a term group having the same background color in the term list 211. The longitudinal length of the term spectrum bar sequence 212 corresponds to the length of the entire document, and one spectrum bar in the term spectrum bar row 212 indicates the position in the document of the corresponding term.

The background of the term spectrum bar sequence 212 and the color of the spectrum bar are colored based on the color information setting. In the example of FIG. 3, since the character background color is selected as the color of the spectrum bar and black is selected as the background color of the term spectrum bar column, the red character is selected in the term group box 210 associated with the classification AA00. Corresponding to "clothes, clothes ... apron" with a background color, the term spectrum of the first column is displayed with a black background color and a red spectrum bar, and "hands, necks, and necks" with a gray character background color. The term spectrum in the second column is displayed with a black background color and a gray spectrum bar corresponding to ".. Shin". If a group of terms with a background color does not exist in the document, the term spectrum bar sequence may be black or hidden.

In this way, the term list 211 and the term spectrum bar column 212 are integrally associated with each other corresponding to the term group, and when the term included in the term list 211 is hit in the document, the corresponding term spectrum bar column 212 is colored. Since it is configured to be displayed, it is possible to easily grasp the relationship between a plurality of term groups and a document while looking down at the multispectral screen.

For example, the user has a bird's-eye view of the term spectrum bar column 212 in the term group box 210 matrix-arranged on the multi-spectral screen 200, and the classification in which many spectrum bars are displayed as in AA00 of FIG. 3 is the content of the document. It can be determined that the relationship with is high. It can also be seen that AA10, AA14, and AA15 are also related. On the other hand, it can be determined that the classifications in which the spectrum bar is not displayed, such as AA11 to AA13 and AB02 to AB03, have low relevance to the contents of the document.

When the user wants to display how a specific term or term spectrum in the term group box 210 is described in a document when the multi-spectrum screen 200 displayed by the term spectrum display means 12 is viewed from a bird's-eye view. There is. Therefore, the document processing apparatus 10 provides a function of simply displaying the corresponding term in the document when a predetermined user operation on the multispectral screen 200 is detected.

For example, when the document display means 11 detects that the user has clicked one term group box 210 in the multispectral screen 200 by operating the mouse, the clicked term group box 210 is highlighted. In FIG. 3, as an example, the term group box 210 with the clicked name “AA00” is highlighted with a broken line frame. Then, the search keyword in the "term panel" column (B) is replaced with the term list 211 corresponding to the selected term group box 210, and the term in the document corresponding to the search keyword is highlighted. At this time, the "term panel" column (B) is replaced, so that the name "AA00" of the selected term group box 210 and the spectrum bar column 212 are displayed in the "spectrum bar" column (E). , The user can scroll through the specification text while looking at the "spectrum bar" column (E). Further, when the user clicks one of the spectrum bars in the term group box 210, in addition to the above operation, the same as when the user clicks the spectrum bar in the "spectrum bar" column (E), " The display content in the "statement text" column (D) is jumped to the corresponding position. Further, the user can select a plurality of term group boxes 210 at the same time. For example, when classification AA12 and classification AA13 are in a superordinate concept and subordinate concept relationship, both term group boxes can be selected at the same time and the corresponding term can be highlighted.

Instead of detecting that the user clicked the specific term group box 210 by operating the mouse, the specific term group box 210 was dragged and dropped on the "term panel" column (B). It may be detected. It may also detect the selection of a particular term in the term list 211 displayed within the term group, or the selection of the particular term spectrum bar column 212, and highlight the term in the corresponding document.

As described above, the user can display the corresponding text of the document by performing a predetermined operation on the multispectral screen 200 after displaying the multispectral screen 200. For this reason, even if you want to analyze the specific content of a document by comparing multiple term groups associated with some meaning with the document, you can display the relevant part of the document with a simple operation. can.

The term spectrum bar row 212 is displayed so as to fit in the term group box 210, but in order to improve the visibility of the term group box 210 or the term spectrum bar row 212, a mode for displaying the term spectrum bar row 212 is used. A mode for hiding may be provided. This mode can also be set arbitrarily by the user. In addition, it may be set automatically according to the frequency of appearance of terms in the document. For example, if the frequency of appearance of a term corresponding to a certain term spectrum bar string is equal to or higher than a predetermined first threshold value, or is equal to or lower than a predetermined second threshold value, the term spectrum bar string is a term related to the content of the document. It may be determined that it is not a spectrum bar string and set to the non-display mode.

Although an example of using the color information set in the term for coloring the term spectrum bar column 212 has been described, other coloring methods can also be adopted. As an example, the number of terms hit in the document may be reflected in the shade of color in the term spectrum bar column. For example, when displaying a term spectrum bar column for a group of "clothes, ... apron" with a red background color, light red when the number of hit terms is small, dark red when the number of hits is large, etc. The color intensity can be changed based on the number of terms.

In FIG. 3, the multispectral screen 200 is superimposed and displayed on the document display screen 100, but the display mode is not limited to this, and the multispectral screen 200 may be displayed as a separate window, for example. Further, the term group box 210 may be reduced and displayed according to a user's instruction, or a scroll bar for scrolling and displaying the multispectral screen 200 in the vertical direction or the horizontal direction may be displayed.

Regarding the display of the term group box 210, it is possible to set the display / non-display mode for each term group box 210, and the term group box has no meaning by the judgment based on the frequency of appearance of the terms as described above. 210 may be hidden.

Further, the term group box 210 has a hierarchical structure, and normally only the term group box 210 in the upper hierarchy is displayed, and the operation (for example, double-clicking with the mouse) to the term group box 210 in the upper hierarchy causes the display. The term group box 210 in the lower hierarchy may be displayed. For example, if there is a term group box associated with the upper hierarchy classification AA00 and each term group box associated with the lower hierarchy classifications AA01 to AA10, it usually corresponds to the upper hierarchy classification AA00. Only the attached term group box is displayed in a form that integrates the terms and the term spectrum bar column of the lower hierarchy, and the term group box of the lower hierarchy is expanded and displayed by operating the term group box. May be good.

In each term group box 210, the name of the term group and the explanation of the meaning associated with the term group may be displayed together. For example, when a term group is associated with an F-term classification, the term group boxes are arranged in a table format of the F-term, and in each term group box, a description of the classification definition is displayed together with a classification symbol. You may do so. Further, the term list 211 may be hidden in each term group box 210.

FIG. 3 shows an example in which a user identifies one term group data set (3B011) and displays a multispectral screen 200 corresponding to this one term group data set, but the user has a plurality of term group data sets. May be specified and a multispectral screen corresponding to a plurality of term group data sets may be displayed. In this case, the multi-spectral screens 200 corresponding to a plurality of term group data sets may be displayed side by side, or may be switched and displayed by a tab or the like.

FIG. 4 is a diagram showing an example of the multi-term panel 300 of the document processing apparatus 10 of the first embodiment. The multi-term panel 300 arranges a term list and color information for each term group included in the term group data set.

The term group display means 13 acquires a designated term group data set from the term group database 50 in response to a "file input" command by the user. Then, the name of the term group, the spectrum background color, the spectrum mark, the term, and the color information of the term are extracted from the term group data set to generate the multi-term term panel 300, which is displayed on the display device 30.

In FIG. 4, the panels from the panel 1 to the panel 8 are displayed as an example. Each panel contains a panel number, a term group name, a spectral background color, a spectral mark, and a term. Further, adjacent to the multi-term panel 300, a "term and color panel" column displaying a combination of a color number, a character color, and a character background color is displayed. Further, at the upper part of the multi-term panel 300, command buttons of "export", "file output", "file input", "color batch setting", and "clear all colors" are provided.

As an example, the multi-term panel 300 of FIG. 4 displays a group of terms associated with the classification of the theme 3B011 of the F-term. In the "spectral background color" column, the setting of the background color of the term spectrum bar column is displayed, and black is selected in the panel 1. In the "spectrum mark" column, the color of the spectrum bar in the term spectrum is specified, and in the panel 1, the spectrum bar is set to be displayed by the character background color of the term.

In the "term" column, a color number indicating a combination of a term of the term group and a character color and a character background color of the term is set. For example, on the panel 1, "clothes, clothes ... apron" is displayed in white text color and red text background color, and "hand, neck ... shin" is displayed in black text color and gray text background color. Is set to be done.

The term group and various color settings of the multi-term panel 300 can be freely edited by the user. When newly creating the multi-term panel 300, the user may manually input all the items, but the term group set in the "term" field is mechanically extracted by the term group creating means 14. The user can edit and create what has been done. For example, as shown in FIG. 4, when each term group is associated with the classification of the F-term, the term group creating means 14 corresponds to the instruction for creating a new term group and corresponds to the designated F-term theme symbol. An existing F-term table may be acquired from the memory, a term may be extracted from the wording of the definition explanation of each classification, and the term may be presented to the user together with the synonym or synonym. Here, it is assumed that all the existing F-term tables and dictionaries of synonyms / synonyms are stored in the document processing apparatus 10 in advance.

As a method for extracting a term group by the term group creating means 14, a term that is a seed of a term group is selected based on a set of documents that are hit by the term group (positive example documents) and a set of documents that are not hit (negative example documents). It may be extracted mechanically.

FIG. 5 is a diagram illustrating an example of a step of creating a positive example document set and a negative example document set for each classification from a patent document set associated with a certain theme with an F-term.

A set of positive and negative literature is created for each F-term classification. For example, when creating a positive example document set and a negative example document set for the classification of AA01, the classification symbols assigned to all the patent documents associated with the target theme are analyzed, and AA01 is assigned. The documents that are present are included in the set of positive examples, and the documents that are not given AA01 are included in the set of negative examples.

FIG. 6 schematically shows an example of a seed term extraction step.

From the positive and negative bibliographic sets, we generate terms that have a significantly higher appearance rate in the positive bibliography than in the negative bibliography. For example, for each term included in the set of regular documents to which AA01 is given, the appearance rate in the set of regular documents, that is, the value obtained by dividing the number of regular documents in which the term appears by the total number of regular documents. calculate. Similarly, for each term included in the negative example literature set to which AA01 is not assigned, the appearance rate in the negative example document set, that is, the number of negative example documents in which the term appears is divided by the total number of negative example documents. Calculate the value.

Then, a term whose appearance rate in the positive example document is significantly higher than that in the negative example document is extracted as a seed term of the term group AA01. The threshold value of the appearance rate, which is the reference for extraction, can be set according to the accuracy of the seed terms to be extracted, the number of seed terms to be extracted, and the like. Further, when extracting the seed term, synonyms and synonyms of the seed term may be extracted together. In this case, it is assumed that the synonym / synonym dictionary is stored in the document processing apparatus 10 in advance. The extracted seed term can be used as it is as a term of the term group, but the extracted seed term is displayed on the display screen and the term to be finally used is selected based on the input from the user. May be. In calculating the appearance rate of seed terms, general terms appearing in any document or terms whose number of appearances is so small that they do not have statistical meaning may be excluded.

In this way, by providing the term group creating means 14, it is possible to extract a term group associated with the meaning of each classification based on a plurality of positive and negative examples already given classification. Since it is possible, it is possible to objectively and comprehensively set the term group that characterizes each classification.

The contents of the multi-term panel 300 newly created or edited by the term group display means 13 are converted into a term group data set and newly saved or overwritten in the term group database 50 when instructed to "output a file". To. Further, when the instruction of "export" is given, the term group data set is exported to the term spectrum display means 12 and displayed on the multi-spectrum screen 200.

As described above, by using the multi-term panel 300, the user can edit and improve the content of the term group at any time, or create a new multi-term panel 300, so that the content of the term group is enhanced. be able to.

<Operation>
Next, an example of the operation of the document processing apparatus 10 of the first embodiment described above will be described.
FIG. 7 is a flowchart for explaining an example of the operation of the document processing apparatus 10 of the first embodiment. When the document processing device 10 is started, the main routines of steps S1, S8, and S10 in FIG. 7 are executed. Steps S2, S3, and S5 to S7 correspond to the function of the document display means 11, step S4 corresponds to the function of the term spectrum display means 12, and step S9 corresponds to the function of the term group display means 13. The steps outlined in this flowchart are exemplary and can be performed in any combination of steps, including combinations that exclude, add, or modify certain steps. Although FIG. 7 illustrates the case where each step is sequentially processed, a parallel programming method such as multi-programming processing may be adopted.

When the document display means 11 detects the display instruction on the document display screen 100 (step S1), the document display means 11 displays the document on the document display screen 100 (step S2). When the document display screen 100 is newly generated, the information for specifying the document (for example, the publication number of the patent document) is acquired from the user, and the corresponding document is acquired from the document database 40. Then, the paragraph structure, the specification text, the code list, and the figure are extracted from the acquired document and displayed on the document display screen 100. The document display means 11 displays a scroll bar on the document display screen 100 as needed. On the other hand, when the document display screen 100 has already been generated but is inactive, the document display screen 100 is activated.

When the search keyword is preset or newly input, the document display means 11 displays the search keyword in the "term panel" column (B). Then, when a term corresponding to the corresponding search keyword exists in the document, highlighting is performed by changing the character color or the background color of the term.

The document display means 11 displays in the “spectrum bar” column (E) a spectrum bar indicating at which position in the document the term corresponding to the search keyword appears in the same color as the background color of the search keyword. ..

In FIG. 7, when the display instruction of the multi-spectral screen 200 by the user is detected (step S3), the term spectrum display means 12 acquires information for specifying the term group data set (for example, an F-term theme symbol) from the user. , The corresponding term group data set (for example, the term group associated with a plurality of classifications of F-term) is acquired from the term group database 50. Then, a plurality of term group boxes 210 are arranged on the multi-spectral screen 200, and the term list 211 and the term spectrum bar string 212 associated with each of the term groups are preset in each term group box 210. Is displayed based on (step S4).

The term spectrum display means 12 selects one term from the term list 211 in order to display the term spectrum bar sequence in the term group box 210, and calculates the position where the term appears in the document. For example, by calculating the number of lines from the first line of the document to the line where the term appears and dividing by the number of lines of the entire document, the relative appearance position in the document is calculated, and the appearance position is one. Displayed as a spectrum bar in the term spectrum bar column. At this time, the spectrum bar is colored based on the color information set in the term. Similarly, all positions where the term appears in the document are calculated and the term spectrum bar sequence 212 containing the plurality of spectrum bars corresponding to these terms is displayed in the color set for the term.

Similarly, for other terms included in the term group, a term spectrum bar string 212 corresponding to each term is generated. When the spectrum bar is displayed, the corresponding term and the position in the document of the term are associated with each spectrum bar and stored in the memory.

In FIG. 7, when a user operation on the document display screen 100 or the multispectral screen 200 is detected (step S5), the document display means 11 responds to the user operation on the document display screen 100 or the multispectral screen 200 to display the document. The display content is controlled (step S6). For example, when it is detected that a certain term group box 210 is selected, the selected term group box 210 is highlighted and the term list 211 in the term group box 210 is displayed in the “term panel” column (B). It is displayed, the document is highlighted in the "specification text" column (D), and the spectrum is displayed in the "spectrum bar" column (E).

When the control of the display contents of the document is completed, the document display means 11 determines whether or not the document display screen 100 is being selected or is being worked on, that is, whether or not the document display screen 100 is active (step S7). When the document display screen 100 is active, steps S3 to S6 are repeated, and when the document display screen 100 is closed or reduced to become inactive, the process returns to the main flow.

In FIG. 7, when the display instruction of the multi-term panel 300 is detected (step S8), the term group display means 13 displays the multi-term panel 300. When the multi-term panel 300 is newly generated, the user waits for the input of the information specifying the term group data set to be displayed and the new / edit command. When such information is input, the term group display means 13 displays the multi-term panel 300. On the other hand, if the multi-term panel 300 has already been generated but is inactive, it is activated and displayed. Then, a new creation process or an editing process of the term group is executed (step S9). When the term group display means 13 detects the "export" command by the user, the term group display means 13 converts the contents of the multi-term panel 300 into a term group data set, and the document display means 11 is instructed to perform the "export" command. The term group data set converted with the notification is output to the data delivery memory (not shown). When the processing by the term group display means 13 is completed or the multi-term panel 300 becomes inactive, the processing flow returns to the main flow.

In FIG. 7, it is detected whether a command for terminating the document processing device 10 has been input (step S10), and if no end command has been input, the process returns to step S1. On the other hand, when the end command of the document processing apparatus 10 is input, the displayed screen is closed and the series of processing of the document processing apparatus 10 is terminated.

As described above, according to the first embodiment, it is possible to provide a document processing device that can easily grasp the relationship between a document and a plurality of term groups associated with some meanings constituting the term group data set. .. In the first embodiment, a term group associated with the F-term classification as a plurality of term groups has been described as an example, but a plurality of term groups associated with some meaning other than the F-term classification may also be described. , The present invention can be applied. For example, in addition to the Japan Standard Industrial Classification, Japanese Standard Occupational Classification, Disease, Injury, and Death Cause Classification, which are used as statistical standards for classification, the Japan Standard Industrial Classification, etc., all have major classification, middle classification, minor classification, and these classifications. It can be said that the document has items to be explained and has a plurality of term groups associated with some meaning.

<Second Embodiment>
The classification assignment support system in the second embodiment will be described. The second embodiment is provided with the document processing apparatus of the first embodiment, and a plurality of term groups constituting the term group data set are associated with a plurality of classifications, and a suitable classification is selected from the plurality of classifications. The present invention relates to a classification granting support system that provides support for granting classification to a document to be classified. Here, the classification is given by attaching a classification symbol to the document when the content of the document to be classified matches the definition of the classification. For example, "AA00", "AA01", etc. in the F-term are assigned classification symbols.

In the second embodiment, as shown in FIG. 1, a classification giving means 15 for giving a classification to a document displayed by the document displaying means 11 is further provided. The user refers to each term group box 210 displayed by the term spectrum display means 12, and particularly selects the term group box 210 which has many spectrum bars and is determined to be highly relevant to the contents of the document. Then, the term list 211 in the term group box 210 is displayed in the "term panel" column (B), the document is highlighted in the "specification text" column (D), and the "spectrum bar" column (E) is displayed. Display the spectrum. Then, the user checks the content of the document centering on the highlighted part, and if it is determined that the definition of the classification associated with the selected term group box 210 matches the content of the document, the classification is performed. Classification is given by the giving means 15. In the method of assigning a classification by the classification assigning means 15, the user may manually input the classification symbol in the classification symbol input field, or the user selects the corresponding classification symbol from the list of classification symbols. You may do it. Further, the classification associated with the term group box 210 may be selected and assigned by operating the term group box 210 displayed by the term spectrum display means 12 (for example, right-clicking with a mouse). When the classification assigning means 15 acquires the classification symbol assigned by the user, it associates it with the displayed document and stores it in, for example, the document database 40.

By the way, in the classification granting business such as granting the classification of F-term to the patent document, a plurality of users (classification grantors) can refer to or edit (register, change) the term group stored in the term group database 50. , Deleted, etc.) In such an environment, the classification assignment support system may have a configuration in which the term group stored in the term group database 50 is shared by a plurality of users and the term can be edited.

As an example, the document processing apparatus 10 is provided with a means (not shown) for controlling access to the term group according to the content of an access request to the term group database 50 by a plurality of users, thereby sharing the term group. It can be realized. For example, when an access request for a predetermined term group in the term group database 50 by a plurality of users is detected, the term group to be edited is different even if the term group is a reference request or the term group is edited. , Allow multiple users to request access to the term group if there is no conflict in the access request. On the other hand, when a conflict occurs in the access request such as an edit request for the same term group, the access request from one user is permitted based on the first-come-first-served basis, the access right level, the edit priority, and the like. In addition, when a conflict occurs, it may be configured to notify the corresponding user that the edited content is in conflict and wait for an instruction from the user.

In this way, the content of the term group can be enhanced by adopting a configuration in which the term group stored in the term group database 50 is shared among a plurality of users who assign the classification.

According to the classification granting support system of the second embodiment, by assuming that a plurality of term groups handled by the document processing apparatus 10 are associated with a plurality of classifications, the contents of the entire document can be grasped and the classification granting grounds can be found. It becomes possible to quickly perform the classification, and it is possible to provide a classification assignment support system that supports high-quality classification assignment using the document processing apparatus 10.

<Third Embodiment>
The document processing apparatus 10 or the classification assignment support system according to the third embodiment will be described. In the example of the first embodiment, the term group creating means 14 extracts a term group corresponding to the meaning of each classification based on a plurality of positive and negative example documents to which classification has already been given, and obtains a term group. Although it was created, in the third embodiment, the term group creating means 14 automatically analyzes the similarity relationship of the extracted terms to generate a literary expression associated with each classification, so that each classification can be created. Create a group of terms.

Here, the sentence meaning expression is a single term or a combination (tuple) of a plurality of terms indicating a co-occurrence relationship described by a Boolean algebraic expression. For example, when the three terms "position", "GPS", and "measurement" often appear at the same time in a phrase, sentence, or paragraph, that is, "position", "GPS", and "measurement" are co-occurrence relationships. If, the sentence expression is set as follows.
・ Sentence expression (phrase tuple) when there is a co-occurrence relationship in the phrase: <position, GPS, measurement>
・ Sentence expression (sentence tuple) when there is a co-occurrence relationship in the sentence: {position, GPS, measurement}
-Sentence expression (paragraph tuple) when there is a co-occurrence relationship in a paragraph: [Position, GPS, measurement]

When the terms that make up such a sentence expression are used as a group of terms and compared with a document, the search will be hit only when a combination of these terms appears within each range of a phrase, sentence, or paragraph. By constructing the classification, the accuracy of classification is significantly improved as compared with the case of searching by a single term.

In addition to the phrase tuples, sentence tuples, and paragraph tuples listed above, neighborhood expressions (expressions described by multiple terms, the maximum number of characters between terms, and the order of terms) should be used as the sentence meaning expression. Is also possible.

Next, a procedure for creating a term group of the document processing device 10 or the classification assignment support system of the third embodiment will be described. This term group creation procedure is executed by the term group creation means 14, and a step of extracting a seed term from a set of positive examples and a set of negative examples, and then a step of further extracting co-occurrence terms to generate a sentence expression. It consists of. Of these, the steps for extracting seed terms from the positive example document set and the negative example document set are as described with reference to FIGS. 5 and 6 in the first embodiment.

FIG. 8 is a diagram showing an example of a step of generating a co-occurrence term and a sentence meaning expression (two-word tuple). Co-occurrence terms are terms that frequently appear in the same phrases, sentences, or paragraphs as seed terms.

When generating a paragraph tuple of classification AA01, a species term group and other term groups are extracted from the term group of the regular document of AA01. First, one seed term is selected from the seed term group and is designated as seed term 1. Among other term groups, terms appearing in the same paragraph as species term 1 are extracted as co-occurrence terms. 2 such as [species term 1, co-occurrence term 1], [species term 1, co-occurrence term 2] ... [species term 1, co-occurrence term n], depending on the co-occurrence terms that appear in the same paragraph as species term 1. Create a word taple. Next, for the seed terms included in the seed term group such as seed term 2 and seed term 3, a two-word tuple in which co-occurrence terms are combined is similarly created.

Next, the effectiveness of the two-word tuple included in the two-word tuple group is evaluated, and finally, a highly accurate two-word tuple that represents the meaning and content of AA01 is selected. For the accuracy evaluation of the two-word tuple, the positive example literature group and the negative example literature group are used. The number of paragraphs or frequency of occurrence of the two-word tapple of the seed term 1 and the co-occurrence term i (i = 1 to n) in the positive example literature set, and the seed term 1 and the co-occurrence term i (in the negative example literature set). Compare the number of paragraphs or the frequency of appearance of the two-word taples of i = 1 to n).

When comparing the number of paragraphs that appear, for example, if a certain two-word tuple appears only in the positive example document and does not appear in the negative example document, the accuracy is 100%. The frequency of appearance of the two-word taple is, for example, the number of paragraphs in which the two-word taple of the seed term 1 and the co-occurrence term i (i = 1 to n) appears in all the paragraphs included in the regular document of AA01. It may be calculated by dividing the value. In the evaluation of the two-word tuple, the evaluation result may be added or corrected by accepting the instruction input by the user.

It is also possible to create a three-word paragraph tuple by adding co-occurrence terms that appear in the same paragraph to the two-word tuple selected in this way. By using a three-word paragraph tuple, it is possible to assign a classification with higher accuracy than a two-word tuple. Similarly, a 4-word paragraph tuple, a 5-word paragraph tuple, and the like may be created.

The term group creating means 14 generates a combination of a species term and a co-occurrence term for each classification, and stores the terms constituting the two-word taple and the three-word taple thus created in the term group database 50. Can be registered as a term in a group of terms. In addition, in the process of generating a seed term or a co-occurrence term, synonyms of the generated term may be generated together and registered as a term of a term group. Further, the term group generated in this way may be displayed on the multi-term panel 300 by the term group display means 13 and edited by the user.

In this way, when the text expression is used as a term group and the document is displayed by the document display means 11, only when a combination of these terms of the sentence expression appears within each range of a phrase, a sentence, or a paragraph. By configuring the term to be highlighted, the relationship between the document and the term group can be grasped more accurately. In the third embodiment, the sentence meaning expression associated with the classification as a term group has been described as an example, but the present invention may be applied to the sentence meaning expression associated with some meaning other than the classification. can.

In the document multispectral screen 400, the document No. displayed in the "reference number list" column (A). 1 to No. A plurality of document boxes 410 are arranged in order from the upper left corresponding to each of X, and a term spectrum bar column 411 is displayed in each document box 410 together with a document number. The term spectrum bar column 411 displays a list of spectrum bars indicating the positions of terms in the corresponding document based on the term and color information set in the "term panel" column (B). The display / non-display mode can be set for each document box 410. For example, the document box 410 of a document having a low relevance to the set term is hidden by a judgment based on the frequency of appearance of the term in the document. You may.

When the user has a bird's-eye view of the document multispectral screen 400, the user may want to display the contents of a specific document in the document box 410 as text. Therefore, the document processing apparatus 10 provides a function of simply displaying the corresponding document when a predetermined user operation on the document multispectral screen 400 is detected.

For example, when the document display means 11 detects that the user has clicked one document box 410 in the document multispectral screen 400 by operating the mouse, the clicked document box 410 is highlighted. In FIG. 9, as an example, the document box 410 corresponding to the document number 15 is highlighted with a broken line frame. Then, the specification text in the "specification text" column (D) is replaced with the document corresponding to the selected document box 410, and the term in the document corresponding to the search keyword is highlighted. At this time, by replacing the "specification text" column (D), the display of the "spectrum bar" column (E) is also changed, so that the user can scroll the specification text while looking at the spectrum bar. can. Further, when the user clicks one of the spectrum bars in the document box 410, in addition to the above operation, the "details" are the same as when the user clicks the spectrum bar in the "spectrum bar" column (E). Jump the display content in the "book text" column (D) to the corresponding position.

In addition, although FIG. 9 shows an example of performing spectrum display based on the term group set in the “term panel” column (B), a plurality of term groups for performing spectrum display are prepared in advance and prepared. The term group may be selectively switched to display the spectrum. For example, as shown in the first embodiment, a plurality of term groups associated with classifications such as F-terms are prepared in advance, and by selecting one of these, a "term panel" column ("term panel" column ( A term group may be set in B) to display a spectrum. In this case, the document multispectral screen 400 and the term group multispectral screen 200 may be switched and displayed, and the term group multispectral screen 200 may be displayed when the term group is selected. In addition, a plurality of documents are arranged in the vertical axis direction and a plurality of term groups are arranged in the horizontal axis direction of the two-dimensional arrangement of the multi-spectral screen so that the spectra can be displayed simultaneously for each of the plurality of documents and for each of the plurality of term groups. May be.

As described above, when the term spectrum bar column 411 is displayed corresponding to each of a plurality of documents and the term set in the "term panel" column (B) is hit in any of the documents, the corresponding term is displayed. Since the spectrum bar column 411 is configured to be colored and displayed, it is possible to easily search for a document closely related to the set term while looking down at the document multispectral screen 400. Further, since the text of the corresponding document can be displayed by performing a predetermined operation on the document multi-spectral screen 400, after a bird's-eye view of the term spectrum bar column 411 of a plurality of documents, the specific document is specified. Even if you want to analyze the contents of a specific description, you can display the relevant document with a simple operation.
