A Study on Extraction Method of Synonyms in Specification Documents

Recently, the document information managed in companies tend to be more complex and various. Specification documents are used for the technical transfer and inheritance of manufactures and services. However, the description and the meaning of the component words in specifications are often inconsistent or multiple, because a specification document is made by the persons in charge of various parts. Then the readers may misunderstand the contents of specifications by them. This paper focuses on synonyms, multiple description of words for a meaning or a word, in specification documents and proposes an extraction method of them considering the co-occurrence words of component words. This paper applies the proposed method to a test data, in which some words in an actual specification document are replaced with another words, and studies the effectiveness of the proposed method.
