Description

In this paper, we report a method for automatically generating a Japanese and English dictionary of synonymous terms using the keyword lists assigned to academic papers by the authors. In our approach, we first generate a keyword graph representing keywords as nodes and their correspondent pairs as links, and then search for erroneous links and polysemous nodes using an efficient graph algorithm in graph theory. Each connected group of terms on the resulting graph constitutes a group of synonymous terms. As a demonstrative example, an online bilingual synonymous terms dictionary is introduced where the proposed method is applied to a set of Japanese and English keywords extracted from real-scale academic conference papers.
