9. A non-transitory computer readable storage medium having stored thereon computer-executable instructions for determining veracity of data in documents stored in a repository, said computer-executable instructions performing a method comprising: creating one or more semantic networks from the documents in the repository, wherein said one or more semantic networks define intra-document and inter-document relationships among terms contained within the documents; responsive to receiving a search query, identifying one or more semantic networks containing nodes matching one or more terms in the search query; determining an edge density for each node matching a term in the search query; calculating a relevancy score for each of the one or more semantic networks based on the edge densities of the nodes matching a term in the search query; determining a relevancy, to the search query, of a first document associated with the one or more semantic networks based on the relevancy score; determining if data from the first document in one of the semantic networks conflicts with data from a second document in one of the semantic networks; determining, in response to a determination that data from the first document conflicts with data from the second document, whether the conflicting data from the first document is obsolete in comparison to data from the second document; wherein said determining if the data from the first document is obsolete further comprises: comparing search frequency information for the data from the first document against search frequency information for the data from the second document; and determining, in response to a determination that the search frequency information for the data from the second document is higher than the search frequency information for the data from the first document, that the data from the first document is obsolete in comparison with the data from the second first document; annotating, in response to a determination that the conflicting data from the first document is obsolete in comparison to data from the second document, a portion of the first document corresponding to the obsolete data with the data from the second document to form an annotated first document; and providing a search result list to the user comprising the second document and the annotated first document.

The non-transitory computer readable storage medium of claim 9 , wherein said method further comprises: providing a link in the annotated first document, wherein the link displays a summary of conflicting data in the documents and sources of the conflicting data.
