Most IR systemsuse a single fixed ranking strategy to support theinformation seeking task of all users for all queriesirrespective of the heterogeneity of end users andqueries.The main problem for this work is that nosingle ranking strategy performs the best for allqueries. This work considers query difference indeveloping ranking function by clustering the query.Then the cluster membership information is combinedinto the learning process of the ranking function inorder to combine the ranking risks of all trainingexamples with different weights according to thetraining query’s similarity to different query clusterfor ranking model construction.To verify the benefit of the proposed querydependentranking system experiments wereconducted on TREC 2003 and TREC 2004 datasets inLETOR (Learning To Rank) package. The rankingaccuracy of the system is evaluated by Normalizeddiscount cumulative gain (NDCG)evaluation metric."}]}, "item_1583103108160": {"attribute_name": "Keywords", "attribute_value": []}, "item_1583103120197": {"attribute_name": "Files", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "date": [{"dateType": "Available", "dateValue": "2019-07-03"}], "displaytype": "preview", "download_preview_message": "", "file_order": 0, "filename": "12055.pdf", "filesize": [{"value": "186 Kb"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 186000.0, "url": {"url": "https://meral.edu.mm/record/3800/files/12055.pdf"}, "version_id": "db16db6a-5266-4757-9961-6b9975830fb5"}]}, "item_1583103131163": {"attribute_name": "Journal articles", "attribute_value_mlt": [{"subitem_issue": "", "subitem_journal_title": "Twelfth International Conference On Computer Applications (ICCA 2014)", "subitem_pages": "", "subitem_volume": ""}]}, "item_1583103147082": {"attribute_name": "Conference papers", "attribute_value_mlt": [{"subitem_acronym": "", "subitem_c_date": "", "subitem_conference_title": "", "subitem_part": "", "subitem_place": "", "subitem_session": "", "subitem_website": ""}]}, "item_1583103211336": {"attribute_name": "Books/reports/chapters", "attribute_value_mlt": [{"subitem_book_title": "", "subitem_isbn": "", "subitem_pages": "", "subitem_place": "", "subitem_publisher": ""}]}, "item_1583103233624": {"attribute_name": "Thesis/dissertations", "attribute_value_mlt": [{"subitem_awarding_university": "", "subitem_supervisor(s)": [{"subitem_supervisor": ""}]}]}, "item_1583105942107": {"attribute_name": "Authors", "attribute_value_mlt": [{"subitem_authors": [{"subitem_authors_fullname": "Lwin, Pwint Hay Mar"}, {"subitem_authors_fullname": "Kham, Nang Saing Moon"}]}]}, "item_1583108359239": {"attribute_name": "Upload type", "attribute_value_mlt": [{"interim": "Publication"}]}, "item_1583108428133": {"attribute_name": "Publication type", "attribute_value_mlt": [{"interim": "Article"}]}, "item_1583159729339": {"attribute_name": "Publication date", "attribute_value": "2014-02-17"}, "item_1583159847033": {"attribute_name": "Identifier", "attribute_value": "http://onlineresource.ucsy.edu.mm/handle/123456789/153"}, "item_title": "Query-Dependent Ranking for Web Information Retrieval", "item_type_id": "21", "owner": "1", "path": ["1597824273898"], "permalink_uri": "http://hdl.handle.net/20.500.12678/0000003800", "pubdate": {"attribute_name": "Deposited date", "attribute_value": "2019-07-03"}, "publish_date": "2019-07-03", "publish_status": "0", "recid": "3800", "relation": {}, "relation_version_is_last": true, "title": ["Query-Dependent Ranking for Web Information Retrieval"], "weko_shared_id": -1}
