WithAir has the following five features. (1) Mobile-contents-focused crawler, that can collect Web pages published for browser phones selectively. (2) Location-based retrieval method, using location-related expressions detection and classification technologies. (3) Ranking and summarization methods for mobile contents, based on link structure analysis. (4) Keyword anticipation method, that can reduce costs of query keyword input operation. (5) Purpose anticipation method, which can estimate the user's purpose from a query keyword and show the pages relevant to it. This paper also describes the evaluation results. They show that WithAir can collect 1.3 million mobile pages with accuracy of 99%, and can select 370 thousand location-related pages with accuracy of 93%. They also show that the operation cost of WithAir is the lowest, compared with conventional mobile search engines.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"76","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告自然言語処理（NL）"}],"bibliographicPageStart":"71","bibliographicIssueDates":{"bibliographicIssueDate":"2001-09-10","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"86(2001-NL-145)","bibliographicVolumeNumber":"2001"}]},"relation_version_is_last":true,"weko_creator_id":"1"}}
