This technique improves document retrieval performance by expanding target spoken documents using Web data. In this research, two types of indexes are built. The one index is made from the transcriptions of the spoken documents, the other is made from Web documents that are highly related to the target spoken documents. The Web documents are retrieved by a search engine that uses Web search queries from transcriptions of the target spoken documents. To utilize both the indexes will achieve robust spoken document retrieval for out-of-vocabulary (OOV) problem and errorful transcriptions by a speech recognizer. The experimental result has shown that the proposed method was very effective for solving the OOV problem. Especially, retrieval performance for only queries including OOV words has achieved improvement of 4.2% comparing with the baseline result.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"7","bibliographic_titles":[{"bibliographic_title":"研究報告音声言語情報処理（SLP）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2009-05-14","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"11","bibliographicVolumeNumber":"2009-SLP-76"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"created":"2025-01-18T23:24:19.646888+00:00","id":62353,"links":{}}
