語義網站點的發(fā)現與排序
發(fā)布時間:2018-08-30 08:00
【摘要】:隨著語義網中RDF數據的大量涌現,語義搜索引擎為用戶搜索RDF數據帶來了便利.但是,如何自動地發(fā)現包含語義網信息資源的站點,并高效地在語義網站點中收集語義網信息資源,一直是語義搜索引擎所面臨的問題.首先介紹了語義網站點的鏈接模型.該模型刻畫了語義網站點、語義網信息資源、RDF模型和語義網實體之間的關系.基于該模型討論了語義網實體的歸屬問題,并進一步定義了語義網站點的發(fā)現規(guī)則;另外,從站點鏈接模型出發(fā),定義了語義網站點依賴圖,并給出了對語義網站點進行排序的算法.將相關算法在一個真實的語義搜索引擎中進行了初步測試.實驗結果表明,所提出的方法可以有效地發(fā)現語義網站點并對站點進行排序.
[Abstract]:With the emergence of a large number of RDF data in the semantic web, semantic search engines have brought convenience for users to search for RDF data. However, how to automatically find sites containing semantic web information resources and efficiently collect semantic web information resources in semantic web sites is always a problem for semantic search engines. Firstly, the link model of semantic site points is introduced. The model describes the relationship among semantic Web sites, semantic Web information resources, RDF models and semantic Web entities. Based on this model, this paper discusses the problem of semantic web entities' attribution, and further defines the discovery rules of semantic site points, and defines the semantic site point dependency graph based on the site link model. An algorithm for sorting semantic site points is also presented. The related algorithms are tested in a real semantic search engine. The experimental results show that the proposed method can effectively find the semantic sites and sort the sites.
