【摘要】:大數(shù)據(jù)時代,從海量的數(shù)據(jù)中發(fā)現(xiàn)對用戶有用的知識成為研究領域重要的問題.通過集成多個搜索引擎的查詢結果,實現(xiàn)食品安全領域中搜索信息的集成和個性化自適應排序.本文設計基于元搜索技術、知識本體和自適應的排序學習技術,實現(xiàn)多個搜索引擎相關查詢結果集成,在對用戶點擊的標注和知識本體的基礎上,利用基于監(jiān)督學習的排序技術,實現(xiàn)對食品安全領域信息的個性化自適應排序.系統(tǒng)實現(xiàn)了集成多個搜索引擎的食品安全相關知識的提取和相關結果的重新排序.本研究不僅實現(xiàn)了多個搜索引擎食品安全信息查詢相關的結果集成,而且能夠根據(jù)用戶的偏好實現(xiàn)結果的自適應排序.
[Abstract]:In the era of big data, discovering useful knowledge from massive data has become an important issue in the field of research. By integrating the query results of multiple search engines, the integration of search information and personalized self-adaptive sorting in the field of food safety is realized. Based on meta-search technology, knowledge ontology and self-adaptive ranking learning technology, this paper designs the integration of query results related to multiple search engines, based on the annotation and knowledge ontology clicked by the user. The self-adaptive ordering of food safety information is realized by using the sorting technology based on supervised learning. The system realizes the extraction of food safety related knowledge and the reordering of the related results by integrating multiple search engines. This study not only realizes the integration of results related to food safety information query of multiple search engines, but also adaptively sorts the results according to users' preferences.
