| Abstract: | Based on tree hierarchical structure of domain ontology,in the paper we discuss and optimise the computational method for conceptual semantic similarity in domain ontology in terms of such factors as distance between two nodes,semantic overlapping degree,semantic depth,semantic density and concept attributes.Its successful application in page-analysis by focused-crawler fully proves its accuracy in quantifying conceptual semantic similarity. |
