BACKGROUND OF THE INVENTION
The present invention relates to a dictionary management program and a computer system for managing dictionary data used for data analysis.
[0002]
[Prior art]
Specific contents of text mining technology include understanding the context based on text data, extracting text data summary, classifying text data, searching text data, etc., extracting knowledge from text data, There is a technique for acquiring quantified information (quantitative information) from information (qualitative information) described in text. In a broad sense, the text mining technique includes a technique for analyzing a result obtained by data mining of text data.
[0003]
In a text mining system (mining engine), analysis processing is executed using a concept definition dictionary.
[0004]
FIG. 13 is a block diagram illustrating the configuration of a conventional text mining system.
[0005]
The text mining system 1 mainly includes an input unit 2, an information extraction unit 3, an output unit 4, and a concept definition dictionary 5.
[0006]
The concept definition dictionary 5 registers various text elements constituting the information described by text and their attributes in association with each other. The text elements registered in the concept definition dictionary 5 are used as judgment criteria in the analysis process.
[0007]
For example, an attribute ID “G001” is associated with a text element “one step lead”. Further, the attribute ID “G009” is associated with the text element “POS is in good order”. The attribute IDs “G001” and “G009” indicate “good information”.
[0008]
The input unit 2 inputs daily report data 61 to 6n collected as analysis target data.
[0009]
The information extraction unit 3 extracts text elements registered in the concept definition dictionary 5 from the input daily report data 61 to 6n, and performs text mining based on the attributes of the extracted text elements. For example, daily report data including a text element indicating “good information” is determined as “good daily report” and extracted.
[0010]
The output unit 4 displays the text mining result 7.
[0011]
Thereby, it is possible to display the daily report data 7 determined to be the “good daily report” among the daily report data 61 to 6n.
[0012]
In the conventional text mining system 1, when it is desired to change the contents of text mining, it is necessary to correct the registered contents of the concept definition dictionary 5.
[0013]
For correction, the concept definition dictionary program is edited using, for example, a text editor. Alternatively, the concept definition dictionary 5 is corrected by inputting a command for instructing correction.
[0014]
[Problems to be solved by the invention]
The work of correcting the concept definition dictionary program with a text editor or the process of correcting the concept definition dictionary 5 by inputting a command needs to be performed by an engineer familiar with the structure of the text mining system 1.
[0015]
Therefore, conventionally, it is difficult for a person who is not familiar with the structure of the text mining system 1 to change the contents of the concept definition dictionary 5.
[0016]
Even a person who is familiar with the structure of the text mining system 1 may cause a bug based on a coding error as a result of editing with a text editor or the like.
[0017]
The present invention has been made in view of the above circumstances, and an object thereof is to provide a dictionary management program and a computer system for facilitating dictionary data correction work.
[0018]

FIG. 3 is a screen displayed by the correction candidate display function 11. With reference to the correction candidate screen 15, the user determines which text element is to be corrected and how.
[0041]
The designation accepting function 12 accepts designation of the content of the correction operation for the concept definition dictionary 5.
[0042]
For example, when the designated correction operation is addition of a text element, the designation receiving function 12 receives designation of a text element to be added and its attribute.
[0043]
FIG. 4 is a screen for adding a text element displayed by the designation receiving function 12. The concept addition screen 16 displays registered text elements, and further displays an area for inputting a text element to be newly added.
[0044]
On the other hand, when the designated correction operation is deletion of a text element, the designation receiving function 12 displays a list of text elements registered in the concept definition dictionary and accepts designation of a text element to be deleted on the list.
[0045]
FIG. 5 is a text element deletion screen displayed by the designation receiving function 12. On the concept deletion screen 17, registered text elements are displayed. The user specifies a text element to be deleted on the list and presses the delete button.
[0046]
Similarly, the designated reception function 12 also supports operations such as changing text elements and adding, changing, and deleting attributes.
[0047]
The correction function 13 corrects the concept definition dictionary 5 in accordance with the specification received by the specification reception function 12.
[0048]
FIG. 6 is a flowchart of the dictionary management method executed by the dictionary management program 8.
[0049]
First, a daily report analysis result screen 14 is displayed (S1), and a user designates a check button (S2).
[0050]
Next, only the daily report data checked by the check button is extracted, and the correction candidate screen 15 is displayed (S3).
[0051]
Next, the modification target element is designated with the mouse on the modification candidate screen 15, and the designated content is accepted (S4).
[0052]
Then, a screen such as the concept addition screen 16 or the concept deletion screen 17 is displayed, and the correction content for the element to be corrected is received from the user (S5), and the concept definition dictionary is corrected according to the received correction content (S6). ).
[0053]
As described above, by using the dictionary management program 8 according to the present embodiment, even those who are not familiar with the structure of the text mining system 1 can easily use the GUI to easily read the contents of the concept definition dictionary. It can be corrected. Moreover, since it can be easily corrected, coding errors can be prevented.
[0054]
Further, by making corrections while referring to the text mining results, the concept definition dictionary 5 can be corrected effectively and appropriately, thereby improving the accuracy of the mining results.
[0055]
In addition, by extracting only the correction candidates and then specifying the correction contents, the user can efficiently and appropriately determine the correction contents.
[0056]
(Second Embodiment)
In the present embodiment, a description will be given of a dictionary management program that, when an element to be corrected is designated, extracts and displays all daily report data including the element and uses it for determining the correction contents of the user.
[0057]
FIG. 7 is a block diagram showing a configuration example of a computer system that executes the dictionary management program according to the present embodiment.
[0058]
The dictionary management program 18 is characterized in that a confirmation screen display function 19 is realized on this system by being read from the recording medium 9 into the computer system. Since the other functions 10 to 13 realized by the dictionary management program 18 have been described above, description thereof will be omitted.
[0059]
The confirmation screen display function 19 accesses the daily report database 20 storing the collected daily report data, and extracts all daily report data having elements designated by the designation reception function 12.
[0060]
Then, the confirmation screen display function 19 displays the extracted daily report data.
[0061]
FIG. 8 is a flowchart of the dictionary management method executed by the dictionary management program 18.
[0062]
Steps (S1 to S4) from when the daily report analysis result screen is displayed until the specification of the element to be corrected is accepted are the same as those in FIG.
[0063]
When designation of the element to be corrected is accepted, all daily report data including the element is extracted from the daily report database 20 and displayed as a confirmation screen (S41).
[0064]
The user considers the correction contents of the element in consideration of the daily report data displayed on the confirmation screen.
[0065]
Then, the correction contents for the correction target element are received (S5), and the concept definition dictionary 5 is corrected (S6).
[0066]
For example, the user will add an attribute indicating “good information” to the element of “sales improvement” of the daily report data displayed on the correction candidate display screen 15a shown in FIG. Suppose that
[0067]
In this case, the user designates this “sales improvement” element using a technique such as reversing with the mouse.
[0068]
Then, as shown in FIG. 10, all daily report data having an element of “Sales floor improvement” is displayed on the confirmation screen 28.
[0069]
As a result, the user determines that it is not desirable to extract the daily report data “A meeting for improving the sales floor” as “good daily report” by text mining, and register the element of “Sales floor improvement”. I can see off.
[0070]
As described above, by using the dictionary management program 18 according to the present embodiment, the user can use not only the result of text mining but also daily report data before text mining for correction determination.
[0071]
Note that the functions executed by the dictionary management program according to each of the above embodiments may be rearranged as long as a similar action can be realized, and the functions may be freely combined.
[0072]
