9. An apparatus for performing a semantic-based analysis of a plurality of documents with regard to a query, the apparatus comprising: a central processing unit (CPU); a content processor for extracting semantic information from content of a plurality of documents, the semantic information including a plurality of factual beliefs, assigning a weight to each of the factual beliefs, the weights being based at least partly on relevance to the query, and assigning links between documents containing related semantic information; a cluster identifier that performs clustering of the plurality of documents by applying a cluster tool to identify documents having content with common information, wherein the cluster identifier adjusts at least one weight of at least one of the weighted factual beliefs or the weighted links to modify at least one cluster of documents; and an inference identifier that determines one or more inferential relationships regarding the query based upon analysis of the plurality of weighted factual beliefs and the links.

The apparatus of claim 9 wherein the inference identifier determines at least one inferential relationship among the extracted semantic information from at least two different documents, wherein the at least one inferential relationship is not explicitly stated in the contents of the at least two different documents, and representing the at least one relationship in an inference graph.
