Abstract

An method for creating an FMEA sheet includes the steps of, retrieving a plurality of documents, dividing words in each of the plurality of retrieved documents into a plurality of morpheme words by morphological analysis, calculating a co-occurrence frequency of each of the plurality of morpheme words, generating a co-occurrence frequency network with morpheme words having a greater co-occurrence frequency than a predetermined level in the plurality of morpheme words, grouping the plurality of documents using the co-occurrence frequency network, extracting a word same as an FMEA word registered in an FMEA word concept dictionary created in advance from each of the plurality of documents belonging to a same group as a word to be used in creating the FMEA sheet and substituting the extracted word to the FMEA sheet.

Claims

1. A method for creating an FMEA sheet, the method comprising the steps of:

retrieving a plurality of documents;

dividing words in each of the plurality of retrieved documents into a plurality of morpheme words by morphological analysis;

calculating a co-occurrence frequency of each of the plurality of morpheme words in each of the plurality of the documents;

generating a co-occurrence frequency network with morpheme words having a greater co-occurrence frequency than a predetermined level in the plurality of morpheme words;

grouping the plurality of documents using the co-occurrence frequency network;

extracting a word same as an FMEA word registered in an FMEA word concept dictionary created in advance from each of a plurality of documents belonging to a same group as a word to be used in creating the FMEA sheet; and

substituting the extracted word to the FMEA sheet.

2. A computer readable medium storing a program to execute the method for creating an FMEA sheet according to claim 1.

3. A device for automatically creating an FMEA sheet comprising:

a memory for storing the program according to claim 2;

a database storing the FMEA sheet;

a CPU for executing the program; and

an operation screen for user operation.

4. The device for automatically creating an FMEA sheet according to claim 3, further comprising:

a morphological analysis dictionary; and

an FMEA word concept dictionary.

5. The device for automatically creating an FMEA sheet according to claim 3, wherein command buttons which are operated by a user to create the FMEA sheet are arranged on the operation screen.
