On diversifying and personalizing web search

David Vallet, Pablo Castells
2011 Proceedings of the 34th international ACM SIGIR conference on Research and development in Information - SIGIR '11  
The obtained results suggest that our proposed combination of diversification and personalization factors may be a way to overcome the notion of intrusiveness in personalized approaches.  ...  Diversification and personalization methods are common approaches to deal with the one-size-fits-all paradigm of Web search engines.  ...  We suggest that this problem of inaccurate personalization approaches can be overcome by adding personalization components to a diversification approach.  ...
