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...
The exponentially increasing cyber threats with the expansion of web applications have become the biggest security concern for e-business and information sharing communities. Current survey shows that application layer is more prone to web attacks. Recent survey carried out by Nation Vulnerability Database shows that, on average 15 new vulnerabilities are released per day, thus proved that existing...
As a model for knowledge description and formalization, ontologies are widely used to represent user profiles in personalized web information gathering. However, when representing user profiles, many models have utilized only knowledge from either a global knowledge base or a user local information. In this paper, a personalized ontology model is proposed for knowledge representation and reasoning...
Safety is a very critical domain in an industrial organization. This is especially true for organizations having multiplicity of scientific and engineering disciplines. This requires a broad based safety management system which has to take into account various aspects consisting of planning, management, preventive measures, compliance to safety standards and response to emergencies. In order to make...
Event processing is a significant evolution in the field of information technology. Semantic link network (SLN) is a semantic data model for managing resources and their semantic relations. This paper proposes a two-layered SLN model for event processing: the matter level and the event level. The event SLN aims to record and manage the evolving process of the matter level. We propose a domain independent...
Formalized representations of knowledge can offer greater flexibility and broader applicability to problem solving programs, by reducing the need for specialized programming. However, this promise can only be fully realized if all of the knowledge required for some task is available in suitable form. The recent increase in popularity of logicbased representations, operating over web-based logical...
Trustworthy network fault diagnosis approach is one critical management item to enhance network trustworthiness. Aiming at gaining highly trustworthy of fault diagnosis in Internet, we present a trustworthy fault diagnosis approach based on integration of Artificial Neural Network and Rule-based Reasoning. Supported by the topology of hierarchical and distributed in multi-domains, reasoning rule matrix...
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...
Web page recommendation model traces userspsila Web-surfing trails, extracts the useful information including keywords, Web page URLs and userspsila evaluations on Web pages, and automatically generates FCA (formal concept analysis) knowledge base and enterprise ontology knowledge base with WordNet. While users are surfing, the system reasons based on the above two knowledge bases, recommends those...
Intelligent Tutoring System (ITS) is one of the important fields of the current computer application. In this paper a Web-based intelligent tutoring system model is designed, the system function structure, the construction of the student model and teaching model, and the reasoning process of the inference engine, finally the system is implemented. The aim of this paper is to provide the Internet learning...
This article describes the work in progress on knowledge-based reconfiguration of a class of automation systems. The knowledge about manufacturing is represented in a number of formalisms and gathered around an ontology expressed in OWL, that allows generic reasoning in description logic. In the same time multiple representations facilitate efficient processing by a number of special-purpose reasoning...
We present an integrated environment for argument-based agent systems, which allows agents to participate in argumentation in the Internet environment, to design knowledge bases, to make and analyze arguments and so on. We demonstrate its usability and advantages on the lines of our LMA-based argumentation scenario
With the expanse of Internet, Web programmers have wide choice of Web services available to them. A need arises for automatic discovery of required Web services and construction of an appropriate sequence of invocation thereof. In this paper, we present a framework for automation of this task based on currently emerging technologies such as ontological knowledge bases, OWL, OWL-S, WSDL, description...
Investigation Organizer (IO) is a collaborative Web-based system designed to support the conduct of mishap investigations. IO provides a common repository for a wide range of mishap related information, and allows investigators to make explicit, shared, and meaningful links between evidence, causal models, findings and recommendations. It integrates the functionality of a database, a common document...
