Abstract:
Efficient utilization of knowledge became a key to the success of an organization. The need to identify experts within or outside an organization has been for a long time inspiration for various initiatives undertaken by academia and industry. The eXtraSpec system developed in Poland is an example of such initiatives. In order to realize its tasks, the eXtraSpec system needs not only to be able to acquire and extract information from various sources, but also requires an appropriate representation of information, supporting reasoning over person’s characteristics. The considered mechanism should allow for a precise identification of required data, but simultaneously, be efficient and scalable. The main goal of this paper, is to present the ontology structure, reasoning approach as well as querying mechanism applied in the eXtraSpec project, and discuss the underlying motivation, which led to the development of a semantic-based mechanism to retrieve experts in its current state.
