Abstract

A computer-implemented method, program, and system for identifying non-self-descriptive terms in electronic documents. The computer-implemented method for identifying a non-self-descriptive term in an electronic document, includes a memory and a processor communicatively coupled to the memory and configured to execute the steps of a method. The method includes acquiring a noun included in the corpus data. The method further includes calculating a qualifying level and a qualified level in the corpus data related to each known in the corpus data. The method further includes identifying one or more nouns included in the corpus data as having a qualifying level and/or qualified level satisfying a predetermined condition. The method further includes presenting a term related to one or more of the nouns in the electronic document as a candidate for the non-self-descriptive term in the electronic document.

Claims

1. A computer-implemented method for identifying a non-self-descriptive term in an electronic document, including a memory and a processor communicatively coupled to the memory, wherein the processor is configured to execute the steps of a method comprising:

acquiring a noun included in corpus data;

calculating a qualifying level and qualified level in the corpus data related to each noun included in the corpus data;

identifying one or more nouns included in the corpus data having a qualifying level and/or qualified level satisfying a predetermined condition; and

presenting a term related to one or more of the nouns in the electronic document as a candidate for the non-self-descriptive term in the electronic document.

2. The method of claim 1 further comprising a step for analyzing the qualification relationships of each noun included in the corpus data.

3. The method of claim 2, wherein the analyzing step includes a step for identifying words qualifying and words qualified by each noun included in the corpus data.

4. The method of claim 2 further comprising:

breaking down compound nouns included in the corpus data into the simple nouns that constitute the compound nouns; and

analyzing step including a step for analyzing the qualification relationships of each simple noun acquired by the analyzing step.

5. The method of claim 1, wherein the terms are frequent terms having a frequency of appearance in the electronic document greater than a predetermined reference.

6. The method of claim 5 further comprising the steps of:

calculating the frequency of appearance of a noun included in the corpus data;

calculating the frequency of appearance of a noun including in the electronic document; and

identifying as a frequent term a noun if the frequency of appearance of a noun included in the electronic document is greater than the predetermined reference in comparison to the frequency of appearance of the noun in the corpus data.

7. The method of claim 5, wherein the frequency of appearance of a noun is calculated by dividing the number of appearances of a noun in the electronic document by the total number of nouns included in the electronic document.

8. The method of claim 1, wherein the qualified level of a noun is calculated by dividing the number of places the noun is qualified by other words and phrases in accordance with a predetermined pattern by a total number of appearances of the noun.

9. The method of claim 1, wherein the qualifying level of a noun is calculated by dividing the number of places the noun qualifies another word in accordance with a predetermined pattern by the total number of appearances of the noun.

10. The method of claim 1, wherein the predetermined condition is satisfied on condition that the qualified level and the qualifying level exceed a predetermined threshold value.

11. The method of claim 1, wherein the presenting step includes a step for identifying as a candidate for the non-self-descriptive term a term which includes at least one noun as a beginning term or an end term.

12. The method of claim 1, wherein the electronic document is a project document related to an information processing system.

13. The method of claim 12, wherein the method further comprises:

acquiring a verbal noun included in the corpus data;

identifying a verbal noun included in the corpus data used on the basis of a verbal noun included in the corpus data expressing a basic action of the information processing system determined beforehand; and

identifying a term including the identified verbal noun as a non-self-descriptive term.

14. The method of claim 13, wherein the basic action of the information processing system includes CRUD (create, read, update and delete).

15. The method of claim 1, wherein the acquiring step includes a step for conducting a mmorphological analysis of the corpus data and extracting nouns.

16. A computer readable non-transitory article of manufacture tangibly embodying computer readable instructions which, when executed, cause a computer to carry out the steps of a method, comprising:

acquiring a noun included in corpus data;

calculating a qualifying level and qualified level in the corpus data related to each noun included in the corpus data;

identifying one or more nouns included in the corpus data having a qualifying level and/or qualified level satisfying a predetermined condition; and

presenting a term related to one or more of the nouns in the electronic document as a candidate for the non-self-descriptive term in the electronic document.

17. A document processing system for identifying non-self-descriptive terms in an electronic document comprising:

a memory;

a processor communicatively coupled to the memory; and

a noun extraction unit for acquiring a noun included in corpus data;

a qualification relationship analysis unit for calculating a qualifying level and a qualified level in the corpus data related to each noun that is included in the corpus data;

a condition determining unit for identifying one or more nouns included in the corpus data having a qualifying level and/or qualified level satisfying a predetermined condition; and

an information processing unit for presenting a term related to one or more of the nouns in the electronic document as a candidate for the non-self-descriptive term included in the electronic document.
