This paper proposes a principled approach for analysis of semantic relations between constituents in compound nouns based on lexical semantic structure. One of the difficulties of compound noun analysis is that the mechanisms governing the decision system of semantic relations and the representation method of semantic relations associated with lexical and contextual meaning are not obvious. | Deverbal Compound Noun Analysis Based on Lexical Conceptual Structure Koichi Takeuchi Kyo Kageura Teruo Koyama Human and Social Information Research Division National Institute of Informatics 2-1-2 Hitotsubashi Chiyodaku Tokyo 101-8430 Japan koichi kyo t_koyama @ Abstract This paper proposes a principled approach for analysis of semantic relations between constituents in compound nouns based on lexical semantic structure. One of the difficulties of compound noun analysis is that the mechanisms governing the decision system of semantic relations and the representation method of semantic relations associated with lexical and contextual meaning are not obvious. The aim of our research is to clarify how lexical semantics contribute to the relations in compound nouns since such nouns are very productive and are supposed to be governed by systematic mechanisms. The results of applying our approach to the analysis of noun-deverbal compounds in Japanese and English show that lexical conceptual structure contributes to the re-strictional rules in compounds. 1 Introduction The difficulty of compound noun analysis is that the effective way of describing the semantic relations in compounds has not been identified. The description should not remain just a kind of categorization. Rather it should take into account the construction of the analysis model. The previous work proposed semantic approaches based on semantic categories Levi 1978 Isabelle 1984 Iida et al. 1984 had proposed detailed analysis of relations between constituents in compound nouns. Some of approaches Fabre 1996 Johnston and Busa 1998 take the framework of Gen- erative Lexicon GL Pustejovsky 1995 . Semantic approaches are especially well designed but they should still clarify the complete lexical factors needed for analysis model. Probabilistic approaches Lauer 1995 Lapata 2002 have been proposed to disambiguate semantic relations between constituents in compounds. Their experimental results show a .
