| Abstract(in English) | In most of previous work, pattern-based approaches or statistical learning model based approaches are applied to extracting bilingual terms from documents. There still remain, however, not small terms that are notextracted because of their low frequency in the documents. In contrast to the previous work, we have proposed an approach to extract new bilingual terms from bilingual term dictionaries because most of new terms can be composed of existing concepts, i.e., constituents of terms. One of the key issues of the proposed approach is how to make suitable clusters in bipartite graph of term constituents for generating proper new terms. In this study we applied two methods of clustering, i.e., Kernighan-Lin algorithm and Spectral Co-Clustering to dividing bipartite graph. The experimental results of generating new bilingual terms in five domains show that the Spectral Co-Clustering based system extracts proper new terms with a maximal of 58% accuracy and finds correct their translations with a maximal of 26% accuracy. In the experimental results of new term extraction task of all domains, the Spectral Co-Clustering system outperforms Kernighan-Lin algorithm based system. |
