【摘要】：現(xiàn)實(shí)世界中信息資源之間存在著各種各樣的關(guān)聯(lián)關(guān)系,而當(dāng)前的搜索引擎只能提供基于關(guān)鍵字的搜索,不能為用戶提供他們所關(guān)心的與關(guān)鍵字相關(guān)的各類信息。針對這個(gè)問題,提出了構(gòu)建語義覆蓋網(wǎng),以用戶需求為導(dǎo)向,以用戶所關(guān)心的信息為中心,將所有與此資源相關(guān)的信息全部匯聚起來提供給用戶。這里先根據(jù)語義相似度將節(jié)點(diǎn)聚類,然后在聚類的基礎(chǔ)上,根據(jù)各類關(guān)聯(lián)關(guān)系構(gòu)建基于關(guān)聯(lián)關(guān)系的語義覆蓋網(wǎng)。
[Abstract]:There are various relationships between information resources in the real world, but the current search engine can only provide keyword-based search, and can not provide users with all kinds of keyword-related information they care about. In order to solve this problem, a semantic overlay network is proposed, which is oriented to the user's needs, takes the information concerned by the user as the center, and aggregates all the information related to this resource to the user. Firstly, the nodes are clustered according to the semantic similarity, and then, based on the clustering, the semantic overlay network based on the association relation is constructed.
