With a large quantity of data and services existing in virtual organization, query routing is an efficient approach to satisfy entities on community for their requirements of knowledge. The entities, which are organized according to the semantic relationship of each other, together with the query routing method under the guidance of semantics, endeavor to meet the querist with the most relevant answer. This paper proposes an extended query routing method that draws on the relationships between different concepts on Domain Ontology to mine the relationship between the knowledge querist holds and the knowledge querist wants. Through Related Segmentation of Ontology Algorithm, this paper tries to explore a cognitive chain to get the querist to fully understand how the knowledge in answer comes about, and to infer the answer querist wants to know.
