Factors Influencing Perceptions Toward Social Networking Websites in China

Based on an online national survey of 503 respondents, this study empirically investigates factors influencing perceptions toward social networking websites (SNWs) in China. More specifically, user demographics and media\ud characteristics were examined. While income was found to be a significant predictor of users’ attitude toward SNWs, gender, age, educational level and marital status were insignificant, suggesting that demographic divides may be\ud diminishing when it comes to online social media in China.

Issues with Evaluating and Using Publicly Available Ontologies

The proliferation of ontologies in the public domain and the ease of accessing them offers new opportunities for knowledge sharing and interoperability in an open, distributed environment, but it also poses interesting challenges for knowledge and Web engineers alike. In this paper we discuss and analyse those challenges with emphasis on the need to evaluate publicly available ontologies prior to use. We elaborate on a number of issues ranging from technological concerns to strategic and political issues. We drawn our experiences from the field of ontology mapping on the Semantic Web, a necessity that enables many of Semantic Web's proclaimed features

Tourists behavior during their trip: How they use and offer recommendations?

The rise of new technologies has changed the way tourists trust in eWOM to choose a restaurant. There is a growing use of opinion and price comparison websites, where opinions and ratings can be shared with other users. In addition, the spreading of false or paid comments has made this type of webs seek the generation and maintenance of trust. However, there are few studies that analyse how to generate trust in these webs and its effect in the intention of the consumer to participate in WOM behaviours, once the tourist is already in its tourist destination. Therefore, this research analyses the influence of recommendations on the generation of tourists’ trust in the review websites of restaurant industry while they are in the destination. A regression analysis of data from 439 tourists has revealed that the perceived credibility, the quality of the information and the quality of the web affect trust in review websites. This fact encourages the contracting of restaurant services and communication among consumers, both in a traditional way (WOM) and through the review websites (eWOM), while the tourist is in the tourism destination.Universidad de Málaga.

Supporting SPARQL Update Queries in RDF-XML Integration

The Web of Data encourages organizations and companies to publish their data according to the Linked Data practices and offer SPARQL endpoints. On the other hand, the dominant standard for information exchange is XML. The SPARQL2XQuery Framework focuses on the automatic translation of SPARQL queries in XQuery expressions in order to access XML data across the Web. In this paper, we outline our ongoing work on supporting update queries in the RDF-XML integration scenario.Comment: 13th International Semantic Web Conference (ISWC '14
