TAILIEUCHUNG - Báo cáo khoa học: "An intelligent search engine and GUI-based efficient MEDLINE search tool based on deep syntactic parsing"

We present a practical HPSG parser for English, an intelligent search engine to retrieve MEDLINE abstracts that represent biomedical events and an efficient MEDLINE search tool helping users to find information about biomedical entities such as genes, proteins, and the interactions between them. | An intelligent search engine and GUI-based efficient MEDLINE search tool based on deep syntactic parsing Tomoko Ohta Yusuke Miyao Takashi Ninomiya Yoshimasa Tsiiriioka Akane Yakiishiji Katsuya Masuda Jumpei Takeuchi Kazuhiro Yoshida Tadayoshi Hara Jin-Dong Kim Yuka Tateisi Jun ichi Tsujii Department of Computer Science University of Tokyo Hongo 7-3-1 Bunkyo-ku Tokyo 113-0033 JAPAN okap yusuke ninomi tsuruoka akane kmasuda tjjug kyoshida harasan jdkim yucca tsujii @ Abstract We present a practical HPSG parser for English an intelligent search engine to retrieve MEDLINE abstracts that represent biomedical events and an efficient MEDLINE search tool helping users to find information about biomedical entities such as genes proteins and the interactions between them. 1 Introduction Recently biomedical researchers have been facing the vast repository of research papers . MEDLINE. These researchers are eager to search biomedical correlations such as protein-protein or gene-disease associations. The use of natural language processing technology is expected to reduce their burden and various attempts of information extraction using NLP has been being made Blaschke and Valencia 2002 Hao et al. 2005 Chun et al. 2006 . However the framework of traditional information retrieval IR has difficulty with the accurate retrieval of such relational concepts. This is because relational concepts are essentially determined by semantic relations of words and keyword-based IR techniques are insufficient to describe such relations precisely. This paper proposes a practical HPSG parser for English Enju an intelligent search engine for the accurate retrieval of relational concepts from Current Affiliation t School of Informatics University of Manchester 2 Knowledge Research Center Fujitsu Laboratories LTD.
