The search result diversification approach based on the HITS algorithm
Shaoping Ma · Journal of Shandong University · 2011
To avoid the problem that users′ diversity needs cannot be precisely obtained or documents provided cannot concern all aspects of the needs in a specific query,a new method was proposed based on the link-parsing feature of the HITS algorithm,in where the possibility was directly calculated according to the diversity of documents in the search result list for a query,and then the result list was re-ranked based on this value.Experimental results on the TREC′s large-scale data collections verified that this method was effective.
