Research on a Method of Conceptual Attribute Acquisition Based on Web
摘要
Abstract
An attribute is the expression of connotation,which is used to explain some property of the conceptual word,and distinguish different concepts,and find their discrepancy. An conceptual word with attribute names are not an isolated vocabulary entry any more. Web-based attribute-acquisition is to acquire a set of attribute names from Web pages automatically for each given concept,enriching the semantics of the concept. Attribute acquisition is also a significant step of general knowledge acquisition from text,and an important task in automatic construction for domain ontologies. It makes a basic classification of attributes according to text knowledge acquisition in this paper and explores basic expressions ( lexico-syntactical patterns) for attribute names in multi-linguistic Web corporal. After acquiring attribute names from large-scale corpus by patterns,a method based on statistics and semantic is proposed to validate. At last,attribute it-eration patterns are applied to acquire new attribute names through iteration method. The results show that the precision of attribute acqui-sition is very high through the experiment of several group concepts.关键词
