Explicit Search Result Diversification through Sub-queries
Queries submitted to a retrieval system are often ambiguous. In such a situation, a sensible strategy is to diversify the ranking of results to be retrieved, in the hope that users will find at least one of these results to be relevant to their information need. In this paper, we introduce xQuAD, a novel framework for search result diversification that builds such a diversified ranking by expli...
متن کاملScore and Rank Aggregation Methods for Explicit Search Result Diversification
Search result diversification is one of the key techniques to cope with the ambiguous and/or underspecified information needs of the web users. In the last few years, strategies that are based on the explicit knowledge of query aspects emerged as highly effective ways of diversifying the search results. Our contributions in this work are two-fold. First, we extensively evaluate the performance ...
متن کاملAggregated Search Result Diversification
Search result diversification has been effectively employed to tackle query ambiguity, particularly in the context of web search. However, ambiguity can manifest differently in different search verticals, with ambiguous queries spanning, e.g., multiple place names, content genres, or time periods. In this paper, we empirically investigate the need for diversity across four different verticals o...
متن کاملSearch Result Diversification
Ranking in information retrieval has been traditionally approached as a pursuit of relevant information, under the assumption that the users’ information needs are unambiguously conveyed by their submitted queries. Nevertheless, as an inherently limited representation of a more complex information need, every query can arguably be considered ambiguous to some extent. In order to tackle query am...
متن کاملA Keyword Based Prototype for Web Search Result Diversification
In web search scenario, users often submit short query terms to search engines, expecting to find their desired information in top ranked results. But their queries are so ambiguous that their actual information needs are often unspecified. To satisfy the different information needs, an effective approach is to diversify the top results retrieved for the query. In this paper, we reduce the dive...
