TAILIEUCHUNG - Báo cáo khoa học: "TEXTUAL EXPERTISE IN WORD EXPERTS: AN APPROACH TO TEXT PARSING BASED ON TOPIC/COMMENT MONITORING"

In this paper prototype versions of two word experts for text analysis are dealt with which demonstrate that word experts are a feasible tool for parsing texts on the level of text cohesion as well as text coherence. The analysis is based on two major knowledge sources: context information is modelled in terms of a frame knowledge base, while the co-text keeps record of the linear sequencing of text analysis. The result of text parsing consists of a text graph reflecting the thematic organization of topics in a text. . | TEXTUAL EXPERTISE IN WORD EXPERTS AN APPROACH TO TEXT PARSING BASED ON TOPIC COMMENT MONITORING Udo Hahn Universltaet Konstanz Informationswissenschaft Projekt TOPIC Postfach 5560 D-7750 Konstanz 1 West Germany ABSTRACT In this paper prototype versions of two word experts for text analysis are dealt with which demonstrate that word experts are a feasible tool for parsing texts on the level of text cohesion as well as text coherence.

Word Experts as a Text Parsing Device This paper outlines an operational representation of the notion of text cohesion and text coherence based on a collection of word experts as central procedural components of a distributed lexical grammar. By text cohesion we refer to the micro level of textuallty as provided . by reference substitution ellipsis conjunction and lexical cohesion cf. HALLIDAY HASAN 1976 whereas text coherence relates to the macro level of textuallty as induced . by patterns of semantic recurrence of topics thematic progression of a text cf. DANES 1974 . On a deeper level of propositional analysis of texts further types of semantic development of a text can be examined . coherence relations such as contrast generalization explanation cf. HOBBS 1979 HOBBS 1982 DIJK 1980a basic modes of topic development such as expansion shift or splitting cf. GRIMES 1978 and operations on different levels of textual macro-structures DIJK 1980a or schematized superstructures DIJK 1980b . The Identification of cohesive parts of a text Is needed to determine the continuous development and Increment of information with regard to single thematic foci . topics of the text. As we have topic elaborations shifts breaks etc. In texts
