SNS (Social Network Service) characterized by Facebook and Twitter has become the next generation paradigm of obtaining data, information and knowledge on the web. The aim of this paper is to recommend relevant expert communities to users on the social network by exploiting the extended object-based thesaurus. It is basically an object- based thesaurus taking the urls of domain experts as its instances...
Recent paradigm shifts in distributed computing such as the advent of cloud computing pose new challenges to the analysis of distributed executions. One important new characteristic is that the management staff of computing platforms and the developers of applications are separated by corporate boundaries. The net result is that once applications go wrong, the most readily available debugging aids...
It is an important knowledge management task to evaluate a user's domain knowledge in a knowledge community. We present a new domain knowledge representation method that considers both user-document associations and document-topic relevance. We provide three alternative user-document association models with varying syntactic and semantic inferences and two alternative document-topic relevance models...
The Internet traffic challenge required the development of a custom application to analyze internet traffic patterns coupled with building access records. To solve this challenge, the author applied the Prajna Project, an open-source Java toolkit designed to provide various capabilities for visualization, knowledge representation, semantic reasoning, and data fusion. By applying some of the capabilities...
The social network analysis (SNA) attempts to find explicit similarities between actors in the network. Traditional clustering methods are based on the attributes between actors in the network that lacks for logic foundation. In this paper we apply rough set theory to SNA. Objects are partitioned into equivalence classes interpreting the hidden community. This paper proposes a framework to find the...
Ontology Web Language (OWL) is an ontology description language for the semantic Web. It is known for its capabilities of representing knowledge and knowledge-based reasoning. OWL has been increasingly used for modeling the entities in pervasive computing environment. However, OWL gives no specific support for exclusive relations between properties owned by subjects, which bring inconvenience for...
In order to build an open, collaborative and efficient visual group learning system (VGLS for short below) in a wide area network (WAN for short below)environment, such as the Internet, this paper studies how to combine multiple techniques such as the mobile agent, ontology and Web services composition to build a VGLS. As the research result, a distributed model for VGLS (DM4VGLS for short below)...
SEMEST+ is an extended version of the software engineering measurement expert system tool (SEMEST), which provides a rule-based software engineering measurement and analysis system on the Internet. The core part of SEMEST+ is the measurement knowledge base. Therefore, how to represent the knowledge of experts is the central issue in designing the system. In classical rule base systems, a rule may...
