The present paper proposes a method by which to translate outputs of a robust HPSG parser into semantic representations of Typed Dynamic Logic (TDL), a dynamic plural semantics defined in typed lambda calculus. With its higher-order representations of contexts, TDL analyzes and describes the inherently inter-sentential nature of quantification and anaphora in a strictly lexicalized and compositional manner. The present study shows that the proposed translation method successfully combines robustness and descriptive adequacy of contemporary semantics. . | Translating HPSG-style Outputs of a Robust Parser into Typed Dynamic Logic Manabu Satof Daisuke Bekkp Yusuke Miyaof Jun ichi Tsujiif f Department of Computer Science University of Tokyo Hongo 7-3-1 Bunkyo-ku Tokyo 113-0033 Japan Ị Center for Evolutionary Cognitive Sciences University of Tokyo Komaba 3-8-1 Meguro-ku Tokyo 153-8902 Japan School of Informatics University of Manchester PO Box 88 Sackville St Manchester M60 1QD UK SORST JST Japan Science and Technology Corporation Honcho 4-1-8 Kawaguchi-shi Saitama 332-0012 Japan f sa-ma yusuke tsujii @is.s.u-tokyo.ac.jp Ị bekki@ecs.c.u-tokyo.ac.jp Abstract The present paper proposes a method by which to translate outputs of a robust HPSG parser into semantic representations of Typed Dynamic Logic TDL a dynamic plural semantics defined in typed lambda calculus. With its higher-order representations of contexts TDL analyzes and describes the inherently inter-sentential nature of quantification and anaphora in a strictly lexicalized and compositional manner. The present study shows that the proposed translation method successfully combines robustness and descriptive adequacy of contemporary semantics. The present implementation achieves high coverage approximately 90 for the real text of the Penn Treebank corpus. 1 Introduction Robust parsing technology is one result of the recent fusion between symbolic and statistical approaches in natural language processing and has been applied to tasks such as information extraction information retrieval and machine translation Hockenmaier and Steedman 2002 Miyao et al. 2005 . However reflecting the field boundary and unestablished interfaces between syntax and semantics in formal theory of grammar this fusion has achieved less in semantics than in syntax. For example a system that translates the output of a robust CCG parser into semantic representations has been developed Bos et al. 2004 . While its corpus-oriented parser attained high coverage with respect to real text the .
