This paper investigates the unification of folksonomies and ontologies in such a way that the resulting structures can better support exploration and search on the World Wide Web. First, an integrated computational method is employed to extract the ontological structures from folksonomies. It exploits the power of low support association rule mining(More)
Collaborative tagging systems have recently emerged as one of the rapidly growing web 2.0 applications. The informal social classification structure in these systems, also known as folksonomy, provides a convenient way to annotate resources by allowing users to use any keyword or tag that they find relevant. In turn, the flat and non-hierarchical structure(More)
We collected bug tracking data from a few popular open source projects and investigated the time related bug reporting patterns from them. The results indicate that along its development cycle, open source projects exhibit similar reliability growth pattern with that of closed source project. Bug arrivals of most open source project will stabilize at a very(More)
An innate characteristic of the development of ontologies is that they are often created by independent groups of expertise, which generates the necessity of merging and aligning ontologies covering overlapping domains. However, a central issue in the merging process is the evaluation of the differences between two ontologies, viz. the establishment of a(More)
Studies in Information Systems (IS) research have widely documented task-oriented and communication structure effects as a result of information and communication technology (ICT) use. These effects have been evidenced at inter- and intra-organisational and occupational community levels. Research on the direct interplay between social network structure, ICT(More)
Theoretical models from social psychology have been widely used by information systems researchers as theoretical foundations to explain and predict information systems use. Unfortunately, most of these models used ignore the social context in which IS is used, but rather focus mainly on the individual and the technology. History and time are as well(More)
