Getting Meaning in the Online Environment of E-Commerce by Using Semantic Web Technologies

This paper treats the problem of information quality from the online environment of e-commerce. We identified some determinants of the information quality considered from the perspective of online buyers. We realized an online questionnaire which analyzes the factors that affect the information quality. We found that, for the online buyer, the semantics of product’s characteristics, the importance of product’s characteristics, and the semantics of product’s price are the main factors. Therefore, we addressed the problem of semantics by using semantic Web technologies and we present our approach in this article. Our study’s results help the e-commerce vendors, responsible with assuring the quality of information provided to their buyers.

Using Resource Description Format in Integrating and Querying Web Data Sources for Semantic Portals

This paper presents with examples the Resource Description Format use in integrating web data sources for semantic organizational portals. We define a vocabulary and describe data in RDF format in order to integrate available Linked data with local data from RDF triple store. We explore this data using SPARQL and we discuss the possible applications for semantic web portals. We conclude by presenting future work and general conclusions.
