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 propose 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.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告情報基礎とアクセス技術（IFAT）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2013-07-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"15","bibliographicVolumeNumber":"2013-IFAT-111"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"id":94344,"updated":"2025-01-21T14:39:28.677002+00:00","links":{},"created":"2025-01-18T23:41:40.397349+00:00"}
