Context-Ontology Driven Focused Crawling of Web Documents

Most of the current focused crawling approaches perform syntactic matching, that is, they retrieve documents that contain particular keywords from the user's query. This often leads to poor discovery results, because the keywords in the query can be semantically similar but syntactically different, or vice-versa. Moreover, the query matching score is calculated taking into account only the keywords from the user's query. Thus, regardless of the context, the same list of results is returned in response to a particular query. This paper presents an approach for document discovery building on a comprehensive framework for context-ontology driven focused crawling of Web documents.
