Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a dictionary construction support apparatus and method for enabling a user to construct an electronic dictionary used in a document classification system for automatically classifying document data.

[0002]

2. Description of the Related Art Various types of electronic data are used every day in various places, and it is said that 80% or more of the data is document data. Various electronic dictionaries are used for the document data depending on the application. For example, a kana-kanji conversion dictionary is used when creating Japanese document data, a morphological analysis dictionary is used when performing morphological analysis on Japanese document data, and a morphological analysis dictionary is used when performing syntax analysis on document data. A parsing dictionary is used. In such electronic dictionaries, there are basically invariable rules that are clearly defined. Therefore, the electronic dictionaries are created and supplied in advance by the product maker, and the user needs such electronic dictionaries. Is used without any particular awareness.

By the way, among various kinds of document data,
In particular, a text mining technique has recently attracted attention as a technique for extracting information necessary for a user from document data described in a free format.

Our company has proposed a method of text mining technology in Japanese Patent Application No. 11-332114, “Business Support System”. This involves extracting important information contained in the target document data by using an information extraction dictionary that holds the concept to be extracted and one or more various expressions representing the concept in association with each other. A method of analyzing document data has been proposed. The expression referred to here refers to, for example, a word, a phrase, a set of words having a co-occurrence relationship, and the like, and the concept referred to herein refers to a higher level common to each of such expressions. Corresponds to the meaning of For example, “owner”, “trainer”, “buyer”, etc. are individual “expressions”, and “person” is a “concept” having a higher meaning of these “owner”, “trainer”, “buyer”, etc. It is.

[0005] The correspondence between concepts and expressions in such an information extraction dictionary does not have a clearly defined invariant rule. It depends on.

[0006] In these information extraction dictionaries, similarly to the electronic dictionary described above, the product maker investigates the usage of the user who introduces the text mining technology, and creates and provides the information extraction dictionaries accordingly. In addition, at present, the results after use are verified, and maintenance such as registration, deletion, and correction in the information extraction dictionary is performed.

This is prepared in advance by a manufacturer other than the user, and no means has been provided for the user to create the dictionary or to edit the dictionary while verifying the created dictionary. Although it was possible to edit the dictionary for information extraction using an editor or the like, it was necessary to fully understand the structure of the dictionary and to edit at the program level, and it could be easily edited by ordinary users. It was not something.

In maintenance of these information extraction dictionaries, the product maker investigates user's troubles after use, judges from the experience, etc., what is considered to be solved, and transfers them to the information extraction dictionaries. The only way to improve the accuracy of text mining was to add, delete, and modify text.

The present invention has been made in view of the above points, and has as its object to provide a support environment for a user to create and verify a dictionary for information extraction.

Next, the operation of the dictionary construction support apparatus of the present embodiment will be described with reference to a flowchart, taking information extraction as an example.

FIG. 3 shows a flowchart of the control unit 101 in the dictionary construction program 100.

When the user requests the dictionary construction program 100 to be activated, the control unit 101 is activated.

After starting the program, the control unit 101 waits for a key input from the user (S201). When a key input is received, first, it is determined whether or not the user input is an end instruction (S202). If it is determined that the instruction is an end instruction, the own program is ended.

On the other hand, if it is determined in step S202 that the input is not an end instruction, it is next determined whether or not the user input is a document designation (S204). If the document is designated here, the designated document data is read from the designated destination, such as a memory, a magnetic disk, or an optical disk, and stored in the text buffer 110a in the internal data holding unit 110 of the memory 40 ( S204). When this process ends, the process returns to the step S201 and waits for the next input from the user.

On the other hand, if it is determined in step S203 that the input is not a document specification, it is next determined whether or not the user input is a dictionary specification (S205). If the dictionary is specified, the specified dictionary is read from the specified destination, such as a memory, a magnetic disk, or an optical disk, and stored in the dictionary buffer 110d in the internal data holding unit 110 of the memory 40 (S206). ). When this process ends, the process returns to the step S201 and waits for the next input from the user.

On the other hand, if it is determined in step S205 that the dictionary is not specified, it is determined whether or not the user input is an expression registration instruction (S207). If it is determined that the instruction is an expression registration instruction, the expression registration unit 1
02 is started (S208). The operation of the expression registration unit 102 will be described later. When the operation of the expression registration unit 102 ends, the process returns to step S201 and waits for the next input from the user.

On the other hand, if it is determined in step S207 that the input is not an expression registration instruction, it is next determined whether or not the user input is a dictionary verification instruction (S209). If it is determined that the instruction is a dictionary verification instruction, the dictionary verification unit 104 is activated (S210). The operation of the dictionary verification unit 104 will be described later. When the operation of the dictionary verification unit 104 ends, the process returns to step S201, and waits for the next input from the user.

On the other hand, if it is determined in step S209 that the input is not a dictionary verification instruction, it is next determined whether or not the user input is a dictionary edit instruction (S211). If the input is a dictionary editing instruction, the dictionary editing unit 103 is activated (S212). The operation of the dictionary editing unit 103 will be described later. When the operation of the dictionary editing unit 103 ends, the process returns to step S201, and waits for the next input from the user.

On the other hand, if it is determined in step S211 that the input is not a dictionary editing instruction, it is next determined whether or not the user input is a difference detection instruction (S213). If the instruction is a difference detection instruction, the difference detection unit 105
Is started (S214). The operation of the difference detection unit 105 will be described later. When the operation of the difference detection unit 105 ends, the process returns to step S201, and waits for the next input from the user.

On the other hand, if it is determined in step S213 that the received instruction is not a difference detection instruction, other designated processing, for example, processing corresponding to a user's input instruction such as environment setting processing is performed (S215), and step S201 is performed. And waits for the next input from the user.

As described above, the control unit 101 analyzes the input of the user, activates various processing units, and stores the document to be processed and the dictionary in the internal data holding unit 110 based on the user's instruction.

FIG. 4 shows a screen display example immediately after the control unit 101 is started. At the top, sign up, verify, edit,
There are buttons for displaying a difference, setting an environment, and terminating. The user selects these processes by pressing these buttons. For example, when the end button is clicked,
In step S202, it is determined that the user input is a termination instruction, and termination processing is performed. Also, for example,
When the registration button is clicked, it is determined in step S207 that the user input is an expression registration instruction,
Processing for activating the expression registration unit 102 is performed.

Below these buttons, an area for inputting a dictionary name is provided on the left and an area for inputting a document name is provided on the right. The user inputs a dictionary name and a document name in these areas, and executes By doing so, the corresponding dictionary or document is read from the storage device 50. For example, when the user inputs a document name in an area for inputting a document name and executes the process, in step S203, it is determined that the user input is a document designation, and in subsequent step S204, based on the input document name, The corresponding document is read from the storage device 50 or the like and stored in the text buffer 110a.

Next, the processing operation of the expression registration unit 102 will be described. FIG. 5 is a flowchart showing the processing operation of the expression registration unit 102.

During the operation of the control unit 101, if it is determined in step 207 that the instruction is an expression registration instruction, the expression registration unit 102 is activated. The activated expression registration unit 102
Starts the expression extraction unit 102a. The activated expression extracting unit 102a analyzes the document data stored in the text buffer 110a by a predetermined analysis method, and creates an expression list (S301). The created expression list is stored in the expression list buffer 110b (S30).
2). The predetermined analysis method may be, for example, when creating an expression list of words, morphological analysis or syntax analysis of document data, extract words, and list the extracted words. The method may be created by various known methods without being limited to the above. After extraction, the expression extraction unit 102a
Ends.

Next, the dictionary data stored in the dictionary buffer 110d and the expression list stored in the expression list buffer 110b are read out and displayed simultaneously (S30).
3).

Next, it is determined whether or not the user input is a dictionary registration instruction (S304). If the instruction is a dictionary registration instruction, the user next specifies an expression to be registered in the dictionary from the displayed expression list (S30).
5). Thereby, the expression registration unit 102 obtains the expression specified by the user. In addition, the user designates a concept for which the obtained expression is to be registered from the displayed dictionary concepts (S306). Thereby, the expression registration unit 102
Get the concept in which the expression is registered. Then, the obtained expression and concept are synthesized and registered as dictionary information (lower-order table) of the expression (S307). This registration is added to the dictionary buffer 110d.

On the other hand, if it is not a dictionary registration instruction in step S304, it is determined whether or not the user input is a dictionary editing instruction (S308). Here, in the case of a dictionary editing instruction, a dictionary editing unit 103 described later is started, and
The dictionary is edited (S309). When the processing of the dictionary editing unit 103 ends, the process returns to step S304.

On the other hand, if it is not a dictionary editing instruction in step S308, the information stored in the dictionary buffer 110d is stored on a magnetic disk or the like (S310), and the process ends.

As described above, the expression registration unit 102 activates the expression extraction unit 102a to create an expression list, and registers a dictionary in the dictionary 109 from the expression list.

FIG. 6 shows an example of a screen display at the time of processing by the expression registration unit 102. A registration button is provided below the area for inputting the dictionary name. By clicking this button, dictionary registration processing (S305 to S307) becomes possible. The contents of the dictionary are displayed below the registration button. In this example, the dictionary name “XXXXXXXXX”
A part of the contents of the dictionary is displayed. In this display,
It is displayed in the form of three layers: class, concept, and expression.
Also, a check box is provided at the front of each word, and the user can specify the check box by clicking the check box.

On the other hand, below the area for inputting the document name,
There are buttons for words, co-occurrences, and phrases. By pressing these buttons, the display contents of the expression list can be selected. The lower part of these buttons is an area for displaying an expression list. In this example, an expression list of a word having a document name “++++++” is displayed. A check box is provided in front of each word (word in this case) in this expression list, and can be specified by the user by clicking the check box.

As described above, on the screen during the processing of the expression registration unit 102, the dictionary and the expression list can be displayed at the same time, and the words of the dictionary class, concept, expression, and expression list are It can be easily specified, and the user can easily register in the dictionary.

FIG. 7 is a diagram schematically showing the expression registration process. This example shows processing of internal data when "employee" is selected from the expression list and added as one expression of the concept of "person".

When "employee" is selected from the displayed expression list, "employee" is obtained from the expression list buffer 110b, and when the concept "person" is selected from the displayed dictionary, it is stored in the dictionary buffer 110d. Concept table 1
Acquire "industry / person" from 22. Then, the acquired "industry, person" and "employee" are combined to obtain "industry / person / employee", which is registered in the expression table 123 of the dictionary buffer 110d. As a result, the expression table becomes 12
It looks like 3 '.

As a result, the expression extracted from the document data can be registered in a desired concept in the electronic dictionary by a simple operation.

Next, the processing operation of the dictionary verification unit 104 will be described. FIG. 8 is a flowchart showing the processing operation of the dictionary verification unit 104.

If it is determined in step 209 that the instruction is a dictionary verification instruction while the control unit 101 is operating, the dictionary verification unit 104 is activated. The activated dictionary verification unit 104
Displays the dictionary data stored in the dictionary buffer 110d (S401).

Next, information is extracted using the dictionary 109, and the result is stored in the processing result buffer 110c (S4).
02). Then, the information stored in the processing result buffer 110d is displayed (S403).

Next, it is determined whether or not the user input is a verification instruction of the information extraction result (S404).

If it is determined that the instruction is a verification instruction of the information extraction result, the node to be verified is specified in the dictionary (S405). Then, the information extraction result corresponding to the designated node is displayed (S406). After this processing, the process returns to step S404.

On the other hand, if it is determined in step S404 that the instruction is not a verification instruction of the information extraction result, it is next determined whether or not the user input is a dictionary editing instruction (S4).
07). Here, if it is determined that the instruction is a dictionary editing instruction, the dictionary editing unit 103 is activated to perform dictionary editing. When the dictionary editing unit 103 ends, the process returns to step S404.

On the other hand, if it is determined in step S407 that the instruction is not a dictionary editing instruction, the dictionary buffer 110
d is stored in a magnetic disk or the like (S4).
09). Further, the information stored in the processing result buffer 110c is stored on a magnetic disk or the like (S410), and the processing of the dictionary verification unit 104 ends.

As described above, the dictionary verification unit 104 verifies the dictionary while displaying the information extraction result by the dictionary 109.

FIG. 9 shows an example of a screen display at the time of processing by the dictionary verification unit 104.

The display content of the left half of the display is the same as the display content of the left half of the expression registration unit 102 in FIG. 6 except that a registration button is provided instead of a registration button. By pressing this verification button, the result verification processing (S405 to S406) becomes possible.

On the other hand, in the display content in the right half of FIG. 9, the extraction result processed by the dictionary 109 is displayed below the document name. Then, as shown in the drawing, after verification of the extraction result, a portion where the expression of the designated concept is present in the extraction result is underlined here so that it can be clearly indicated to the user. It should be noted that any method other than underlining, for example, a method that can sufficiently identify colors and the like may be used.

Thus, the concept in the hierarchized electronic dictionary can be specified by a simple operation, and the expression included in the specified concept can be easily extracted and specified from the extraction result extracted by the electronic dictionary. As a result, the user can easily verify the quality of the electronic dictionary.

Next, the processing operation of the dictionary editing unit 103 will be described. FIG. 10 is a flowchart illustrating the processing operation of the dictionary editing unit 103.

When it is determined, the dictionary editing unit 103 is activated.

The activated dictionary editing unit 103 displays the dictionary data stored in the dictionary buffer 110d (S5).
01).

Next, it is determined whether or not the user input is a node addition instruction (S502). If the instruction is an addition instruction, an additional node is designated (S503). Then, a child node is added to the designated node (S50)
4). Additional content is entered directly by the user. And
It returns to step S502.

On the other hand, if it is not an addition instruction in step S502, it is next determined whether or not the user input is a node deletion instruction (S505). If the instruction is a deletion instruction, a deletion node is designated (S506).
Then, the designated node and all child nodes of the node are deleted (S507). Then, the process returns to step S502.

On the other hand, if it is not a deletion instruction in step S505, it is next determined whether or not the user input is a node change instruction (S508). Here, in the case of a change instruction, a change node is designated (S509).
Then, the character string and value of the designated node are changed (S510). Then, the process returns to step S502.

On the other hand, if it is not a change instruction in step S508, it is next determined whether or not the user input is a node copy instruction (S511). If the instruction is a copy instruction, a copy source node is designated (S51).
2). Then, a copy destination node is designated (S513).
Then, the designated copy source node and all of its child nodes are added to the child nodes of the copy destination node (S514). Then, the process returns to step S502.

On the other hand, if it is determined in step S511 that the instruction is not a copy instruction, it is determined whether or not the user input is an instruction to move a node (S515). Here, in the case of a move instruction, a move source node is designated (S516).
Then, the destination node is specified (S517). Then, the designated source node and all of its child nodes are moved to child nodes of the destination node (S518). And
It returns to step S502.

On the other hand, if it is not a move instruction in step S515, the information stored in the dictionary buffer 110d is stored on a magnetic disk or the like (S519), and the process ends (S515).

As described above, the dictionary editing unit 108 adds, deletes, changes, copies,
Move and perform dictionary editing.

FIG. 11 shows an example of a screen display at the time of processing by the dictionary editing unit 103.
