Semantic preloading in the adaptive Web query

At present query based on Web is short of adaptability. This is caused by the absence of common sense knowledge relative to the conception queried, and information system often makes a basic mistake. In the paper, we introduce a formal model of ontology, modeling semantic relation between conceptions of ontology through a conception called associate-degree. This model facilitates the processing of common sense knowledge, which is the base of semantic extension and preload, builds context relation and association of the conception queried, and brings adaptability to information query based on Web.
