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.
