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)
The Open Source Software(OSS) movement has attracted considerable attention in the last few years. In this paper we report our results of mining data acquired from SourceForge.net, the largest open source software host-ing website. In the process we introduce Association Rules Network(ARN), a (hyper)graphical model to represent a special class of(More)
The evolving vision of Web 3.0 is based on the balanced integration of diverse services provided by human agents and machines over the World Wide Web. This is also the intuition that drives crowdservicing, which helps in creating platforms on which new applications and even enterprises can be build. Crowdsourcing as a concept as well as a practice refers to(More)
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)
The negative consequences of information overload are well understood across a range of disciplines even though the causative factors that contribute to it have not been coherently researched. We apply the concept of 'aversion to loss' from prospect theory and explore its effects in the context of information processing for decision making. A controlled(More)
In this paper, details of Embrapa's Information Agency will be presented. It was designed as a space for exchange of knowledge among farmers, agricultural researchers and rural extension technicians. In the system, information is organized using two criteria. Firstly, every identified resource is cataloged in accordance to Dublin Core Metadata Standard.(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)
