Abstract
Information overload and privacy protection become critical issues with blogs. This paper presents the ontological subscription and blocking system (OSBS) using policies, ontologies, and rules to subscribe interesting posts and block unwanted posts. This system also uses rules for automatic conflict detection between polices. The effectiveness of two subscription systems, OSBS and RSS (rich site summary) reader, is compared. The experimental results reveal that the perceived privacy benefits on the novel OSBS are better than the existing RSS reader. The novel OSBS is as good as existing RSS reader from perceived information overload alleviation perspective.
Highlights
Blogs, which are popular social media, allow net surfers to create and exchange user-generated content in their online social networks based on Web 2.0 technology [1,2,3]
This study evaluate the effectiveness of two subscription systems for blogs: the proposed ontological subscription and blocking system (OSBS) mechanism and the existing rich site summary (RSS) reader
Over 73% of participants in OSBS group, which is more than 69.8% in RSS reader group, agree that “the data is well organized by this system on blogs.”
Summary
Blogs, which are popular social media, allow net surfers to create and exchange user-generated content in their online social networks based on Web 2.0 technology [1,2,3]. Two approaches can mitigate online information overload and control received messages for privacy protection: subscription and blocking. Readers use a subscription mechanism to express their message needs and publishers deliver published content to readers that have specified interest in it [11, 12]. Ontology can provide meanings and semantics to aggregate user-generated content in social media [13]. This paper presents the ontological subscription and blocking system (OSBS). The OSBS approach uses the ontologies and rules to provide interesting blog posts as well as blocking undesired blog posts. Delivering content according to information needs, user profiles, and device characteristics Finding emergent knowledge from annotated blog posts based on ontologies. This study uses the experimental method to evaluate the effectiveness of two blogs subscription systems: OSBS and RSS reader.
