Analysis of navigational interfaces through the use of knowledge representation schemes

Currently, the most digital repositories include knowledge representation schemes such as ontologies and thesauri in order to offer to creators and experts several alternatives able to manage, sort and organize learning objects within a repository. Also facilitate the use of the repository to help users locate learning objects, displaying additional information, identify relationships, categories, areas of expertise. However, these classification schemes sometimes have not been used and exploited to the extent desirable due to: i) users are not familiar with the complex systems of knowledge representation, which experts and creators of repositories used to classify resources, and ii) the current user interfaces do not always provide the essential tasks of users who visit the repository: search and locate digital resources. The motivation of this article focuses on the second factor, presenting a gap analysis of the activities of search and navigation through the design and implementation of navigational interfaces from the use of knowledge representation schemes.
