35. The method of claim 28, for an additional document further comprising: parsing said additional document into a plurality of elements; generating a first representation of each of said elements from the parsing step; for selected pairs of documents drawn such that a first member of the pair is the additional document and a second member of the pair is from said plurality of documents, determining a first utility measure based on the respective first representation of the plurality of elements for the documents in that pair; generating a second representation of each of said elements from the parsing step; for selected pairs of documents drawn such that a first member of the pair is the additional document and a second member of the pair is from the plurality of documents, determining a second utility measure based on the respective second representation of the plurality of elements for the documents in that pair; and wherein in the displaying step, the plot is a scatter plot, generating an overlay plot in contrasting color to the scatter plot, the first coordinate equal to the first utility measure computed on the pairs of documents including the additional document the second coordinate is equal to the second utility measure computed on the pairs of documents including the additional document.

The method of claim 35 wherein: the first representation is a conceptual-level representation; and the second representation is a term-based representation.
