This paper emphasizes the process of extraction and classification of Expression Named Entity(ENE) in non-structured Chinese text, attempts to construct pattern collection for matching and builds the ENE Extraction Model Based Hierarchical Pattern Matching(HPM_ENE_EM), which is the base of the application research on intelligence, such as Competitive Intelligence System(CIS),user interest degree gaining and so on. At last, the paper discusses the detailed application of this model used for extracting the abbreviative terms in academic papers.

Key wordsExpression named entity      Hierarchical pattern matching      Term extraction      Abbreviative terms
