User interface for summarizing the relevance of a document to a query

1. A system for summarizing the relevance of a document to a conceptual query, the system comprising:

a memory having computer readable computer instructions; and

a processor for executing the computer readable instructions, the computer readable instructions including:

receiving the conceptual query, the conceptual query comprising a listing of one or more concepts in a concept graph;

accessing concepts extracted from the document, the concepts extracted from the document based on one or more differential tests performed on portions of text in the document and at least a subset of concepts in the concept graph;

computing a degree to which the conceptual query is related to each of the extracted concepts, the computing responsive to a metric that measures a relevance between the one or more concepts in the conceptual query and each of the extracted concepts the computing comprising using a transition probability matrix to perform a weighting of each link in the concept graph that connect the one or more concepts in the conceptual query to the extracted concepts;

creating a summary by selecting a threshold number of the extracted concepts having a greatest degree of relation to the conceptual query; and

outputting the summary including the selected threshold number of the extracted concepts.

2. The system claim 1 , wherein at least one concept in the summary is not one of the one or more concepts in the conceptual query.

3. The system of claim 1 , wherein the computing further comprises iterating a Markov chain derived from the concept graph.

4. The system of claim 1 , wherein the summary is output to a user interface.
