17. The method of claim 16 wherein determining a semantic similarity score further comprises the steps of: determining a first term-to-term semantic similarity score; computing a tuple-to-tuple semantic similarity score: computing a text-to-text semantic similarity score by combining the term-to-term semantic similarity score and tuple-to-tuple semantic similarity score.
