具語意搜尋功能之異質性教材整合系統

Abstract

[[abstract]]隨著數位學習的發展，數位教材的製作越來越方便且容易，而這些數位教材大多仍是分散在各個學習網，不但降低了教材的重複使用性，學習者也不容易獲得這些資源。對此IMS曾發表過DRI(Digital Repositories Interoperability)標準，目的是希望促使分散的教材資源能夠相互交換，但至今仍只有雛型。雖然目前已有釵h管理教材資源的系統，但對於異質教材的整合依然沒有一套完整的標準。因此，本研究希望發展一個完善的學習物件儲存庫(Learning Repository)，以解決異質教材整合及跨平台搜尋的問題，而我們的方法主要是藉由收集各個異質教材的後設資料(Metadata)，並將這些教材整合至本地的儲存庫，讓使用者能透過簡單的介面輕易的取得想要的教材。而在搜尋機制方面，本研究也結合了Ontology技術提供語意相關的搜尋(Semantic Search)，以給予使用者更多的搜尋建議。

[[abstract]]With the development of e-Learning, the production of learning contents has been more convenient and easy, but most of learning contents are scattered in various places. This makes the reusability of learning contents decreased, and learners are also not easy to access the resources. IMS has proposed the Digital Repositories Interoperability (DRI) standard which facilitates the interoperability of learning contents, but the standard was still a prototype so far. Similarly, although several systems have been proposed for managing learning contents, there is yet no good enough standard on integrating the heterogeneous learning objects. Thus, the objective of this thesis is to develop a learning repository to solve the problem of the integration of heterogeneous learning objects and the problem of searching across platforms. Our approach is to collect and store the metadata of heterogeneous learning objects in the repository, and provide users a simple interface to easily access these learning objects. Furthermore, semantic search is provided based on ontology.
