dc.description.abstract© 2013 IEEE.Educational portals are environments that provide student and teacher users access to a variety of learning objects, among which are the educational videos. However, searching for such videos can be time-consuming and unproductive if only general syntactic descriptions are considered. Thus, an architecture of an educational semantic portal prototype, AvaOne, was conceived, implemented, and evaluated. Four experts in user profile and interaction design participated in the heuristic evaluation of this portal, and the results allowed changes and implementations of improvements in the system user interface, to make it more pleasant and engaging. The usability tests of AvaOne were conducted with university professors and graduate students through experiments and questionnaires. The results indicated that metadata embedding into educational videos through related descriptors facilitates and defines the search and access to specific content in the videos, which is favored by the semantic correspondence established between the data, which validates the hypothesis of this study. Therefore, AvaOne is recognized as a real, scalable, and flexible solution that enables the reuse of educational videos through its segmentation.
