52. The method of claim 39 , further comprising: inputting keywords, obtaining a hit list for said keywords, and restricting the neighbors to be displayed to those neighbors which are found on the hit list. 53. The method of claim 52 , further comprising: forming a subgraph from said hit list and all links among the documents in said hit list, obtaining restricted link analysis scores LA (sub) for each of said documents by performing link analysis on said subgraph, and ranking the neighbors according to the subgraph similarity neighbor score 
 SNW (sub)( O,B ) =g·S ( O,B ) +h·LA (sub)( B ) +m·FQS ( B ), where g, h, and m are tuning parameters.
