The Similarity of Text Based on Hierarchical Network of Concept

A model of semantic-based text formalization, Context Framework Model, is presented in this paper. Based on the similarity of context framework, the filtering task can be transferred to the similarity computing among semantic terms. The algorithm, dealing with the domain of the text and the semantic role of the object, computes the synonymy, polysemy and the combination among concepts, and focus on the confusion of commendatory and derogatory.
