A User Interface For Semantic Competence Profiles

Competence management systems are increasingly based on ontologies representing competences within a certain domain. Most of these systems represent a user's competence profile by means of an ontological structure. Such semantic competence profiles, often structured as a hierarchy of competences, are difficult to navigate for self-assessment purposes. The more competences a user profile holds, the more challenging the comprehensive presentation of profile data is. In this paper, we present an integrated user interface that supports users during competence self-assessment and facilitates a clear presentation of their semantic competence profiles. For evaluation, we conducted a usability study with 19 students at university. The results show that users were mostly satisfied with the usability of the interface that also represents a promising approach for efficient competence self-assessment.
