摘要:
A unique system and method is provided that facilitates improving relevance of search results over the initial searching ranking. The system and method involve obtaining relevancy feedback for at least one search result (user rated) and then generating a connectivity graph or web-graph (for Web searches) for the user rated result. The relative distance between results (or pages) in the graph can indicate relevancy between those results. Thus, results within a particular distance from the rated result can be considered related to the rated result and thus, relevant or irrelevant depending on the particular rating for that result. The connectivity graph can be employed to determine a re-ranking of the search results.
