31. A computing device with a processor and memory for augmenting a corpus of documents, comprising: a corpus store containing the corpus of documents; a component having computer-executable instructions that generate a corpus concept graph from the documents of the corpus, the corpus concept graph indicating connections between concepts of the documents of the corpus; a component having computer-executable instructions that determine whether connectedness of concepts of the documents of the corpus is sufficient based on analysis of the connections between concepts of the documents of the corpus as indicated by the corpus concept graph; and a component having computer-executable instructions that, when it is determined that the connectedness of some concepts is not sufficient, adds to the corpus documents relating to the concepts that do not have sufficient connectedness wherein the computer-executable instructions of the component are stored in the memory for execution by the processor.
31. A computing device with a processor and memory for augmenting a corpus of documents, comprising: a corpus store containing the corpus of documents; a component having computer-executable instructions that generate a corpus concept graph from the documents of the corpus, the corpus concept graph indicating connections between concepts of the documents of the corpus; a component having computer-executable instructions that determine whether connectedness of concepts of the documents of the corpus is sufficient based on analysis of the connections between concepts of the documents of the corpus as indicated by the corpus concept graph; and a component having computer-executable instructions that, when it is determined that the connectedness of some concepts is not sufficient, adds to the corpus documents relating to the concepts that do not have sufficient connectedness wherein the computer-executable instructions of the component are stored in the memory for execution by the processor. 32. The computing device of claim 31 wherein the instructions that generate a corpus concept graph include instructions that generate document concept graphs for the documents of the corpus indicating connections between concepts within a document by identifying concepts of the document and indicating strength of the connections between the concepts of the document and wherein the corpus concept graph is created from the document concept graphs.
