Systems and methods to search in response to query consisting of a plurality of keywords, by processing for relevance of all possible valid relations among keywords in the query The overall space of all possible valid relations among all of the keywords in the underlying documents are pre-computed based on transitivity rules using common property items in associated ontologies The query keyword are substituted by considering each keyword as well as valid groups as a whole, based on all reachable valid keywords along every relation computed in the overall merged ontologies Building the knowledgebase with the classification of keywords in different ontologies, fundamentals of building hierarchical part-of graph augmented with same-as and kind-of relations including the change relations, to search the hierarchical graph in response to an user query, selecting the best valid match and the corresponding presentation sheets and finally displaying the results to users.
