On Views in the Semantic Web

چکیده
The Semantic Web is an extension of the current Web in which information on the Web is given well-defined meaning, better enabling computers and people to work in cooperation. The technical foundation of the Semantic Web is RDF, a semi-structured data model resembling directed labelled graphs. Semantics of data are given by ontologies that are encoded using a specialized vocabulary called RDF Schema. First efforts in actually implementing Semantic Web applications with RDF show that views over RDF data can be very beneficial to gain the intended semantic interoperability allowing RDF data to be filtered and restructured. This paper carefully analyzes the situation constituted by the data model, comparing RDF Schema with well-known object-oriented data models and introduces a specialized view mechanism for ontology-based RDF models.

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. As a way of computing recommendations, the ultimate goal of the user-ba...

Introduction: Autism is a nervous system disorder, and since there is no direct diagnosis for it, data mining can help diagnose the disease. Ontology as a backbone of the semantic web, a knowledge database with shareability and reusability, can be a confirmation of the correctness of disease diagnosis systems. This study aimed to provide a system for diagnosing autistic children with a combinat...
