A Method of Semantic Dictionary Construction from On-line Encyclopedia Classifications

This paper introduces a method of constructing a semantic dictionary automatically from the keywords and classify relations of the web encyclopedia Chinese WikiPedia. Semantic units, which are affixes (core/modifier) shared between many phrased-keywords, are selected using statistic method and string affix matching, also with other units to explain the semantic meanings. Then the result are used to mark the semantic explanations for most WikiPedia keywords by analyzing surface text or upper classes. The feature form ´ structure or advantages comparing to other semantic resource are also concerned.
