What Brings Linked Data Web to OpenCourseWare (OCW) Repositories




Edmundo Tovar (UPM) y Nelson Piedra (UTPL, GICAC-UPM)


OpenCourseWare (OCW) is one of the most successful emerging initiatives in the global promotion of free and unrestricted access to university knowledge. This initiative has had a major impact and has prompted many international prestigious universities have joined this movement, creating their own projects in coordination with OCW Consortium. The repository and the organization and internal structure of an OCW are diverse, and respond to the vision of each university. There is no standardized way to implement OCW initiatives, so that one of the greatest challenges facing OCW initiatives in general, as the OCW Universia in particular, is the heterogeneity of existing OCW repositories. The lack of interoperability makes the discovery, reuse and remix of OCWs.

The search and discovery of educational resources in OCW repositories have the same limitations as the search tools of Web Documents: wide range of results, similarity search based on words and not meanings, or problems of ambiguity in the results returned, etc. . This lecture shows how the principles of Linked Data have the ability to enhance the search and discovery of OCWs created and shared by the universities that are part of OCW-Universia.
