BACKGROUND OF THE INVENTION
The present invention relates to a document processing apparatus, a document processing method, a program, and a recording medium for managing an electronic document, and more specifically, a technique for performing a search or classification using document attributes and analyzing a document group. About.
[0002]
[Prior art]
In general, a system for managing digitized documents supports bibliographic information such as document name, creation date and update date, and supports analysis of document groups such as search and classification.
In addition, information extracted from keywords and part of document contents is used as bibliographic information for individual documents, document groups are analyzed, keyword extraction and information extraction from document contents are automated, and the document database Conventionally, the convenience of registering a document in a document has also been improved (see, for example, JP-A-9-6792).
In addition to the supplementary information prepared in advance in the document, in a system that allows users to define information to be attached to the document, it is possible to define the attribute item name and item type at the time of document registration or document update. The item value can be entered according to the item type defined by the user at any time including, or can be entered automatically.
It has also been conventionally performed to collectively define a plurality of document bibliographic information and document incidental items described above as document attributes. For example, you can define attribute names, define multiple item names and item types included in the attributes, and use them as document types. Change the number of items in the attribute and edit the item name / type. It is possible to select a document attribute when registering or updating a document, and substitute an item value according to the type of each item.
For bibliographic information and document attributes of such documents, you can extract several documents from the document group by specifying the bibliographic information values and document attribute values as search conditions, or classify them based on those values. For example, document groups have been analyzed.
In addition, as a technology that supports searching for documents that have been searched using the specified search conditions, document search instructions similar to those already presented, and documents that have a different viewpoint from that document, There is a technique described in Japanese Patent No. 2581376.
[0003]
[Problems to be solved by the invention]
In these conventional methods, when editing document attributes such as the name of the attribute of the document defined by the user, the name of the item included in the attribute, and the change of the item type, before and after the editing, Because the attribute type is different, if you specify the old attribute type and perform a search, you cannot search for documents that correspond to the new attribute type, and you can specify search conditions even if you record and manage such edit records. There was a problem of becoming complicated.
Also, when the system classifies a document group, it does not take into account the relationship before and after such editing, so that the desired search result and classification result may not be obtained.
The present invention has been made in order to solve the above-described problems, and even when there is a change in the name of the attribute of the document, the name of the data item included in the attribute, the data type, etc., the attribute before and after the change is changed. An object of the present invention is to provide a document processing apparatus, a document processing method, a program, and a recording medium that can be used for searching and classification, thereby reducing a user's effort to manage changes in document attributes and the like.

DETAILED DESCRIPTION OF THE INVENTION
The configuration and operation of the embodiment of the present invention will be described below in detail with reference to the drawings.
(1) Functional configuration
FIG. 1 is a block diagram showing a functional configuration of a document processing apparatus as an example of an embodiment of the present invention.
The document processing apparatus according to the present embodiment includes a control unit 100, a document registration unit 110, a document attribute assignment unit 120, a document attribute editing unit 130, an analysis processing execution unit 140, a document storage unit 150, a document attribute storage unit 160, a document attribute. And an editing history storage unit 170.
The control unit 100 controls the entire document processing apparatus when the user designates document registration, document attribute editing, document attribute assignment, analysis execution, etc. by operating an input device such as a keyboard.
The document registration unit 110 inputs a document via an input device such as a scanner, a camera, and a keyboard, or a network, and registers the input document in the document storage unit 150. The document registration process and its result can be confirmed by an output device such as a display or a printer.
[0009]
The data structure of the document storage unit 150 includes a document identifier (document ID) for managing a document, a document name, a bibliographic item (registration date, registrant name, update date, document format (for example, text information) for each document. , Image information, audio information, etc.), document size, notes, etc.), attribute ID, data item list, content list, etc. (see FIGS. 2 and 3). Here, the attribute ID is a unique name for identifying the attribute registered in the document attribute storage unit 160, and the data item list holds an actual value corresponding to the data item of the attribute indicated by the attribute ID. The content list is a list of file identifiers that store content indicating the contents of the document (data such as text, images, and audio).
The document attribute editing unit 130 defines an attribute name to be given to the document, an item name included in the attribute, a data type of the item, and the like, and registers the attribute in the document attribute storage unit 160. Once the attribute of the registered document is extracted from the document attribute storage unit 160, the result of editing can be re-registered in the document attribute storage unit 160 and updated. Of course, attributes themselves and data items can also be deleted.
The editing process and result of the attribute of the document can be confirmed by an output device such as a display or a printer.
The data structure of the document attribute storage unit 160 (see FIGS. 4 and 5) defines attribute data items to be assigned to each document, and is identified by an attribute ID. That is, each document has a variable data item defined here in addition to the bibliographic item, and this data item corresponds to that of the document storage unit 150. This variable data item has a flag indicating whether or not to use this variable data item, the data type of this data item (character type, character string type, date type, name type, numeric type, logical type, etc.) and this data item It consists of a triple pair with the name.
[0010]
FIG. 5 is an example of attributes used in the description of the present embodiment. As an attribute name, an arbitrary name (for example, “abc”) can be defined. As shown in this example, multiple items can be defined together in the attribute. As the data item name and data item data type (value type), the data item name is the document print date and the data item. The data type for is defined as a date type.
An example of editing an attribute registered in the document attribute storage unit 160 in FIG. 5 is shown in FIG. 6 (state before editing) and FIG. 7 (state after editing).
In FIG. 6, the attribute name is changed from “abc” to “xyz”, the data item name “document printing date” is set to “last printing date”, and the data item name “drawing distinction” is set to “character string”. “Type” is changed to “Numeric type”, and “Customer code” is added to the name as a data item, and “Numeric type” is added to the data type. Also, the attribute “abc” itself can be deleted.
The attribute editing operation may be performed using a screen as shown in FIG.
The registered attribute reference screen shown in the upper part of the screen in FIG. 8 displays a list of attributes already registered in the document attribute storage unit 160. Also, the new definition screen at the bottom of the screen of FIG. 8 shows an edit screen for a newly defined attribute. In this example, the attribute “new” is defined. In this new definition screen, the name and item type of each item type are defined. At this time, the entire attribute or a part of the items included in the attribute can be selected and defined from the registered attribute reference screen. Here, all data items of the attribute “abc” and the attribute “ghi” are selected and set as a new attribute “new”.
This attribute can be defined by using two or more attributes shown on the registered attribute reference screen.
For example, when the attributes “a”, “b”, “c”, and “d” are defined on the new definition screen from the attributes “A” and “B” shown on the registered attribute reference screen, the relationship between the two is illustrated. A relationship such as 9 is possible. From the left in the figure
・ Define a by adding all items of attribute A and newly defined items
-Select a part of the item of attribute A and define b
-Define c from the sum of attribute A and attribute B items
・ Define d from the product of attribute A and attribute B
[0011]
The document attribute assigning unit 120 associates the document extracted from the document storage unit 150 with the attribute extracted from the document attribute storage unit 160, substitutes the value of an item included in the attribute, and the like. The associated document and attribute are registered in the document storage unit 150. The process of associating the attribute with the document and the result can be confirmed by an output device such as a display or a printer.
For example, the document attribute assigning unit 120 will be described with reference to FIG. In this example, an attribute is associated with the document registered in the document storage unit 150 by the document registration unit 110 or the document “Iroha” already registered in the document storage unit 150.
In FIG. 10, the attribute “xyz” of the document “Iroha” already assigned is selected from the attribute name list (the right part of the screen) registered in the document attribute storage unit 160. And have changed. Further, after selecting the attribute “abc”, the value of each item defined in the attribute is substituted as shown in FIG. These editing results are registered in the document storage unit 150 in a format corresponding to the document contents.
The analysis processing execution unit 140 retrieves a document group from the document storage unit 150 after the user sets search and classification conditions from an input device such as a keyboard and a pointing device, and refers to the specified conditions. Processing such as search and classification is executed (details will be described later). The analysis process of the document group and the result can be confirmed by an output device such as a display or a printer.
[0012]
The document attribute editing history storage unit 170 records a history of editing processing executed by the document attribute editing unit 130. The data structure of the document attribute editing history storage unit 170 (see FIG. 12) is a triple of the attribute ID, the editing date, and the attribute ID of the attribute based on the editing for each attribute editing registration date. It is represented by The document attribute storage unit 160 and the document attribute edit history storage unit 170 are managed as one by adding the edit date of the data structure of the document attribute edit history storage unit 170 of FIG. 12 to the data structure of the document attribute storage unit 160. May be.
For example, in FIG. 12, the attribute “abc” in FIG. 6 is newly defined on March 31, 1983, edited on July 28, 1996, like the attribute “xyz” in FIG. The case where the attribute “xyz” is changed on the same day is shown. When the data item “customer code” is deleted as in this editing, the flag indicating whether or not the data item can be used is “No”.
When the attribute editing history is expressed, the data structure of the document attribute storage unit 160 is uniquely managed in the document attribute storage unit 160 for each attribute data item as shown in FIG. ”And“ from ”indicating which data item of which attribute is diverted, and by adding the edit date of the attribute, the document attribute edit history storage unit 170 transfers to the document attribute storage unit 160. Two or more attributes that are integrated and are the basis of editing can be expressed.
For example, as shown in FIG. 14 (document attribute storage unit 160), a new attribute “OPQ” is defined using a part of the data item of attribute “abc” defined on June 10, 1982. think of.
[0013]
First, the management item “1” uniquely managed in the document attribute storage unit 160 is assigned to the data item “print date” of the attribute “abc”. If this is used, this management number “1” is assigned to “from” of the attribute “OPQ”, and a unique management number “101” is given as its own management number. Next, the data item “approver” of the attribute “abc” is assigned a management number “2” that is uniquely managed in the document attribute storage unit 160, and this is assigned to the “affiliation head” in the attribute “OPQ”. When the name is changed, this management number “2” is substituted for “from”, the name and type are changed, and a unique management number “102” is given as its own management number.
If a new attribute “UVW” is defined using all data items of attribute “abc”, “1 / AID001” is displayed for “from” of data item “print date” of attribute “OPQ”. "Is substituted, and the unique management number" 201 "is given as its own management number. “AID001” on the right side of “/” represents a unique identifier of the attribute “abc” edited and registered on June 10, 1982, and “1” on the left side of the attribute “abc” represents the data item “print date” of the attribute. Shows a unique management number.
Further, as a method of changing only the attribute names such as attribute IDs “AID001” and “AID002” and “AID005” and “AID006” in FIG. 14, for example, the attribute name is “1999 outgoing document”. It may be used when the document is changed to “2000-origin document” in 2000 or the attribute name “development room” is changed to “first development section” due to organizational change or the like.
[0014]
(2) Search processing in the analysis processing execution unit
FIG. 15 is a flowchart for explaining a processing procedure of search processing in the analysis processing execution unit 140.
First, the user inputs a search condition for searching for a document registered in the document storage unit 150 from an input device such as a keyboard (step S100).
It is checked whether or not the input search condition includes an attribute name or an attribute item name (step S110). If not included, the process proceeds to step S150, and a normal search is executed with the search condition.
If it is included, the document attribute storage unit 160 and the document attribute edit history storage unit 170 are referred to, and an edit history corresponding to the attribute name and the item name of the attribute included in the search condition is extracted (step S120). .
It is checked whether there is an edit history corresponding to the attribute name or attribute item name included in the search condition (step S130). If not, the process proceeds to step S150. If there is, a new search condition is added from the retrieved history. (Step S140).
For example, referring to FIGS. 5 and 12, when the search condition is designated to search for a document group having the attribute “xyz”, the attribute “abc” from which this attribute is created is generated. It is added to the search condition so as to search for a document group having.
In addition, when the value of the data item “approver” of the attribute “xyz” is specified as a search condition, the corresponding data item “document checker” of the attribute “abc” from which the attribute was created is changed. Add included search criteria.
[0015]
In order to refer to the editing history of attributes and items, it is easier to find the data structure of the document attribute storage unit 160 as shown in FIG.
For example, with reference to FIG. 14, if the value of the data item “print date” of the attribute “OPQ” is specified in the input search condition, the data item referred to when creating this data item will be described. That is, the data item “print date” of the attribute “abc” can be found. (A record using the management number “1” is left when the data item of that attribute is defined in the management number “101” in FIG. 14).
Therefore, the data item having the management number “1” is acquired from the document attribute storage unit 160, and the name “print date” of the data item associated with the attribute “abc” can be added to the search condition.
A normal search of the document storage unit 150 is executed using the added search conditions (the search conditions input from Steps S110 (No) and S130 (No) remain unchanged) (Step S150).
The search result is output to an output device such as a display or a printer (step S160). When outputting this result, the document group directly searched from the search condition specified by the user and the document group searched from the condition that the document processing apparatus has expanded the search target are distinguished by color, group, etc. Convenient for users.
If this embodiment is configured in this way, the history when the attribute name, the name of the data item included in the attribute, the data type, etc. are edited is recorded, so that information is used. Thus, when a search is performed by specifying the attribute before or after editing as a condition, the search target can be expanded based on the editing history.
[0016]
(3) Classification processing in the analysis processing execution unit
FIG. 16 is a flowchart for explaining the processing procedure of the classification processing in the analysis processing execution unit 140.
First, a user in the document storage unit 150 designates a document group to be classified by an input device such as a keyboard or a mouse, and various settings such as a classification method to be performed on the designated document group and information attached thereto. (Step S200).
Next, the bibliographic items, contents, and attributes of the document to be classified are quantified (step S210).
For example, when there are a document A and a document B having the same attribute as shown in FIG. 17, the quantification is considered to be the number of data items that differ when the values of the data items are viewed as a complete match. The difference is 2 (type and document number).
If the difference between the values of the data items is used, the difference is 1+ (45-30) = 16. This is 1 because the drawing and invoice are different, and the document number is calculated by calculating the difference between the values.
[0017]
Here, the difference between the drawing and the invoice is not set to 1, the drawing is defined as (x, y) = (4,7), the invoice is defined as (x, y) = (10,15), etc. Can also be used as a difference. In this case, the “reuse degree”, “amount of browsing”, and the like are determined in advance for the axis, and are converted into numerical values for each document.
Further, not only the difference in the number of items but also the difference in the edited date and time, the difference due to the editing of the name and data type of the data item, etc. may be quantified. For example, as shown in FIG. 18, if the same document C is created on the 12th and edited on the 15th and 18th, the difference between the 12th and 15th documents is the difference between the document numbers (45-30). It may be calculated by multiplying the date difference by 3.
In addition, for quantification of document contents, a method using the difference in the number of included words can be considered.
Furthermore, in order to obtain the difference between two arbitrary documents, it is possible to make a numerical value using the frequency of words. An example will be described in which a morphological analysis is performed on a document, words are extracted, a “document × word” matrix is created, and a distance between specific document vectors is calculated.
[0018]
With this word set as a column and the document set as a row, the columns of this matrix are increased as follows. The column names to be increased are the management numbers (for example, “1”, “2”, “101”, “102”) shown in FIG.
For example, in the case of belonging to the attribute name “OPQ” of the document, a non-zero (this may be 1 or a weight) may be substituted for the elements of the column names “101” and “102”, and the attribute name “OPQ” "From" is referenced, and non-zero is substituted for the elements of column names "1" and "2".
The distance is calculated (= classified) using the matrix thus expanded.
For each document quantified in this way, the specified document group is classified by a classification method designated by the user such as cluster analysis (step S220), and the classification result is displayed on a display or printer. The data is output to the output device and presented to the user (step S230). By configuring the embodiment as described above, the history when the attribute name, the name of the data item included in the attribute, and the data type are edited is recorded. Effects can be achieved.
(1) Even if the attributes before and after editing are specified as search conditions, the search can be expanded based on this editing history, so that the user can change the attribute. You can search without worrying.
(2) When classifying a document group, the proximity between attributes before and after the editing can be quantified and used to classify the document group reflecting the document attribute editing history.
[0019]
