TAILIEUCHUNG - Báo cáo khoa học: "Combining a Chinese Thesaurus with a Chinese Dictionary"

In this paper, we study the problem of combining a Chinese thesaurus with a Chinese dictionary by linking the word entries in the thesaurus with the word senses in the dictionary, and propose a similar word strategy to solve the problem. The method is based on the definitions given in the dictionary, but without any syntactic parsing or sense disambiguation on them at all. As a result, their combination makes the thesaurus specify the similarity between senses which accounts for the similarity between words, produces a kind of semantic classification of the senses defined in the dictionary, and. | Combining a Chinese Thesaurus with a Chinese Dictionary Ji Donghong Kent Ridge Digital Labs 21 Heng Mui Keng Terrace Singapore 119613 dhji@ Gong Junping Department of Computer Science Ohio State University Columbus OH j gong @cis .

The method is based on the definitions given in the dictionary but without any syntactic parsing or sense disambiguation on them at all. As a result their combination makes the thesaurus specify the similarity between senses which accounts for the similarity between words produces a kind of semantic classification of the senses defined in the dictionary and provides reliable information about the lexical items on which the resources don t conform with each other. 1. Introduction Both TongYiCi CiLin Mei. et al 1983 and XianDai Han Yu CiDian 1978 are important Chinese resources and have been widely used in various Chinese processing systems . Zhang et al 1995 . As a thesaurus TongYiCi CiLin defines semantic categories for words however it doesn t specify which sense of a polysemous word is involved in a semantic category. On the other hand XianDai HanYu CiDian is an ordinary dictionary which provides definitions of senses while not giving any information about their semantic classification. A manual effort has been made to build a resource for English . WordNet which contains both definition and classification information Miller et al. 1990 but such resources are not available for many other languages . Chinese. This paper presents an automatic method to combine the Chinese thesaurus with the Chinese dictionary into such a resource by tagging the
