A Lightweight Ontology for Rating Assessments.
Cristiano Longo, Lorenzo Sciuto · 2007
Abstract. Various recommender systems and trust engines use application specific formats to store and exchange data. Such data are used for statistical purposes, or to produce recommendations about items or users. This paper introduces Ratings Ontology, a semantic web format for ratings and related objects. This ontology aims to be lightweight, in the sense of minimising the physical size of data stored or sent over the network for a given ratings set. Moreover, we presents a tools suite based on this ontology to find out statistical information from a ratings data set. 1
