A Study on Extraction Method of Synonyms in Specification Documents

Abstract

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.

Automatically refining synonym extraction results: Cleaning and ranking

“…They leveraged the power of query click logs and millions of web tables, and optimised synonym decisions globally. Kawai et al [10] proposed an extraction method for synonyms in specification documents. Their approach makes reference to similarities in contextual information – that is, the words in the co-occurrence vector based on the thesaurus – in order to consider the similarity of meaning or use between the co-occurred words.…”

Automatic discovery and ranking of synonyms for search keywords in the web

“…Finding synonyms from the web is a challenging task as they can be associated with general terms unlike aliases that apply only to people. Kawai et al (2012) proposed a synonym extraction method in specification document by considering the co-occurrence words of component words. Simanovsky and Ulanov (2011) proposed a pattern extraction algorithm to extract the text fragments between pairs of synonyms by exploiting on large scale repositories, namely Wikipedia.…”
