| Abstract(in English) | Query expansion method using pseudo-relevance feedback is significantly effective for microblog search because the query expansion method can solve the vocabulary mismatch problem when searching short documents such as twitter messages (i.e. tweet) limited to 140 characters of content. The pseudo-relevance feedback approaches assume that the top ranked documents in the initial search results are relevant, which contain good topic-related words for relevance feedback. However, that assumption is often invalid because the initial search results may largely contain non-relevant documents and only a small share of the suggested expansion words are useful. Many others are either harmful or useless. To overcome the limitation of pseudo-relevance feedback for microblog search, we pro-pose novel query expansion method based on two-stage relevance feedback frameworks modeling search interests by manual tweet selection and integrating lexical and temporal evidence into its relevance model. Our experiments on a corpus of microblog data (Tweets2011 corpus) show that our two-stage relevance feedback approaches considerably improve search result relevance without decreasing retrieval over almost all topics. |
