1. A computer based link analysis method for determining a context-based relevance of a first electronic document of a plurality of electronic documents to remaining electronic documents of said plurality of electronic documents, comprising:
- populating a weighted symmetric similarity matrix S with link weights representing a measure of similarity between pairs of said plurality of electronic documents;
determining all nonzero entries S(D,X) in a row of said similarity matrix S corresponding to an electronic document D summing said nonzero entries of at least a submatrix S'"'"' of similarity matrix S to produce a first importance score regarding said electronic document D; and
one of searching, navigating and ranking at least a subset of said plurality of electronic documents based on a total score including said first importance score.
