Extending Open Rating Systems for Ontology Ranking and Reuse
نویسندگان
چکیده
Ontology reuse saves costs and improves interoperability between ontologies. Knowing which ontology to reuse is difficult without having a quality assessment. We employ user ratings to determine the user-perceived quality of ontologies. The combination of an Open Rating System (ORS), user ratings, and information on trust between users, allow us to compute a personalized ranking of ontologies. In this paper, we present our extension, the Topic-Specific Trust Open Rating System (TS-ORS). To overcome the limitations of the ORS, the TS-ORS features topic-specific trust and multi-faceted ratings. In a user study, we show that having user ratings and result ranking based on a TS-ORS significantly facilitates ontology assessment and selection for the end user.

Topic-Specific Trust and Open Rating Systems: An Approach for Ontology Evaluation
To achieve better interoperability among intelligent applications, and to relieve knowledge engineers from the burden of developing ontologies from scratch, it is critical to reuse ontologies. However, there are two main reasons why the reuse of ontologies is rare: (1) current ontology repositories allow only simple keyword-based search facilities, and (2) even when a user finds an ontology, th...
متن کاملAn Integrated Ontology Ranking Method for Enhancing Knowledge Reuse
The Semantic Web is a mesh of information linked up such that it can be easily processed by machines. The focus of semantic web is to share data instead of documents and the ontologies act as the mainstay of the semantic web. Ontologies are used to represent domain knowledge in semantic web. As ontologies have many applications in various prominent fields, ontology reuse is becoming increasingl...
متن کاملMetrics for Ranking Ontologies
Representing knowledge using domain ontologies has shown to be a useful mechanism and format for managing and exchanging information. Due to the difficulty and cost of building ontologies, a number of ontology libraries and search engines are coming to existence to facilitate reusing such knowledge structures. The need for ontology ranking techniques is becoming crucial as the number of ontolog...
متن کاملExtending the HPKB-Upper-Level Ontology: Experiences and Observations
This paper describes our experience of extending the HPKB-upper-level ontology. Reuse by extension is key to reuse of generic upper-level ontologies, and we report on the use of structuring principles in this task. We argue that the documentation of design rationale is key to the reuse of this type of ontology, and that the HPKB-upper-level ontology would benefit from reorganisation.
متن کاملSearching and ranking ontologies on the Semantic Web
The number of ontologies available online is increasing constantly. Tools that are capable of searching, retrieving, and ranking ontologies are becoming crucial to facilitate ontology search and reuse. In this document, we describe OntoSearch, which is a tool for capturing and searching ontologies on the Semantic web. We also briefly describe AKTiveRank which is used to rank OWL ontologies base...
