Semantic Navigation on the web: the LCSH case study
نویسندگان
چکیده
In this paper, an innovative ontology-based, information seeking process is proposed, capable of aiding searchers in their quest to fulfill their information needs. Such a process supports multilinguality and concept disambiguation in a way that prevents overcrowding the screen while exposing the expressiveness of the underlying ontology. In order to assess the effectiveness of the proposed approach in a real-world scenario, a prototype web-based application is developed by utilizing the hidden knowledge existing within the authority records of the Online Public Access Catalog – OPAC located at the library of the Ionian University in Greece. More specifically, the underlying Library of Congress Subject Headings LCSHs have been employed to formulate an ontology in OWL format. Interaction with library users is facilitated through an intuitive, web-based GUI implemented in AJAX technology.

One of the most famous methods for recommendation is user-based Collaborative Filtering (CF). This system compares active user’s items rating with historical rating records of other users to find similar users and recommending items which seems interesting to these similar users and have not been rated by the active user.

In general, Policy-based approaches play an important role in the management of web services, for instance, in the choice of semantic web service and quality of services (QoS) in particular. The present research work illustrates a procedure for the web service selection among functionality similar web services based on WS-Policy semantic matching. In this study, the procedure of WS-Policy publi...
متن کاملProbabilistic Relational Reasoning in Semantic Robot Navigation
We examine the use of semantic web resources in robot navigation; more specifically, in qualitative navigation where uncertain reasoning plays a significant role. We propose a framework for robot navigation that connects existing semantic web resources based on probabilistic description logics, with probabilistic relational learning and planning. We show the benefits of this framework in a real...
