Improve Web Search Diversification with Intent Subtopic Mining [chapter]

Aymeric Damien, Min Zhang, Yiqun Liu, Shaoping Ma
2013 Communications in Computer and Information Science  
In this work, we aim to improve the performance of search results diversification by generating an intent subtopics list with fusion of multiple resources.  ...  Result diversification is usually adopted to deal with those queries, in which search engine tries to trade-off some relevancy for some diversity to improve user experience.  ...  In a future work, we would like to combine these data with document ranking and compare the results with some commercial search-engines results.  ...
