摘要:近些年來,隨著計算機的普及和信息技術的快速發(fā)展,導致人們對網絡信息資源的需求持續(xù)升溫,因此獲取信息的方式越來越重要。傳統(tǒng)的信息檢索主要提供給用戶的主要是基于關鍵字的檢索接口,但在信息的查全率和查準率上不高,無法滿足用戶的需求。因此,如何幫用戶實現(xiàn)具有高效率的信息檢索的智能搜索系統(tǒng),已經成為當下研究的重要問題。 傳統(tǒng)的搜索引擎使用的是基于關鍵字的詞匯層次上的信息檢索,這種方法并不能處理用戶的真實語義,導致當前的搜索引擎的召回率和準確率不能令人滿意。本論文研究了目前語義WEB搜索的主流技術,確定了基本的原型框架的實現(xiàn)方法,研究了基于本體的語義搜索框架的建立過程,并嘗試模擬從語義上處理用戶的搜索請求的過程,基本完成了基于本體的語義智能搜索的前期研究工作。 關鍵詞:本體 信息檢索 語義 框架
Abstract:At present,with the rapid of development of information technology,it causes the continued increase of people's demand of the information for the network,so the way to obtaining information becomes very important.The traditional tools of information retrieval can only offer imports based on key words,but the recall and precision information retrieval is not high,which is unable to meet the needs of users. Traditional search engines use the information retrieval based on the keyword vocabulary level, this method can not handle the user's real semantics, leading to the recall and accuracy of the current search engines is not satisfactory. In this thesis, the current mainstream technology of the Semantic Web search to determine the basic prototype implementation of the framework, the process of establishing the framework of ontology-based semantic search, and try to simulate the user's search request from the semantic processing process, and basically complete a preliminary study of the semantic intelligent search. Key Words:ontology information retrieval semantics
