| Abstract: | Aiming at the efficiency of knowledge fusion,the authors extended the structure of conventional topic maps.This new structure embodied the multi-level,multi-granularity and inherent relevant characteristics of knowledge.A new distributed knowledge fusion architecture based on extended topic maps was built up,and a novel algorithm of the similarity of topic maps based on comprehensive information was proposed by integrating syntactic similarity,semantic similarity and pragmatic similarity.It gave full consid... |
