This paper proposes a method for identify- ing synonymous relations in a bilingual lex- icon, which is a set of translation-equivalent term pairs. We train a classifier for identi- fying those synonymous relations by using spelling variations as main clues. We com- pared two approaches: the direct identifi- cation of bilingual synonym pairs, and the merger of two monolingual synonyms. We showed that our approach achieves a high pair-wise precision and recall, and outper- forms the baseline method.
