e-Learning is the use of technology to enable people to learn anytime and anywhere. It is fast, relevant, dynamically changing and can include training, the delivery of just-in-time information and guidance from experts. The semantic web technology in which information in machine-processable form can coexist and complement the current web with better enabling computers and people to work in co-operation...
The harmonization of CIM (IEC 61968/61970) and IEC 61850 standards is a major issue in the interoperability between smart grid devices, systems and applications. This paper describes how Ontology Matching methods, mainly developed for the Semantic Web, can be employed to solve the problems or mismatches that appear in this harmonization. The paper also includes a description of the ESODAT software...
The paper presents a content packaging ontology to represent the semantics of the SCORM Content Aggregation Model, which is a distance e-learning technical specification for promoting reusability and interoperability of learning object among different tools and systems. This ontology model solves the problem that the SCORM XML-Schema model lacks semantics and reasoning capabilities. The ontology consists...
This paper, remote education learning resource for metadata standards that learning resources in the semantic status of the missing, to analyze learning resource metadata,as well as learning resource metadata and ontology integration, combining meta-data ontology with domain ontology to form a learning resource ontology, instantiating the metadata ontology and domain ontology, using IEEE LOM metadata...
Automation of business transactions between trading partners is an important factor in today's global business. XML based e-Business standards are developed to provide a shared understanding on what information to share, when and how between trading partners. However these standards can only capture the syntax of the transactions and not the semantics. This paper presents an ontology for ebXML Business...
Next-generation patients are far from being peripheral to health-care. They are central to understanding the effectiveness and efficiency of services and how they can be improved. Today a lot of patients are used to reviewing local health services on-line but this social information is just stored in natural language text and it is not machine-accessible and machine-processable. To distil knowledge...
Nowadays, with the appearance of more and more web services, it has been one of the key points that how to find the target service quickly and precisely. Traditional methods of web service discovery are only based on the keyword matching, but it's very difficult to realize more detailed and intelligent services, and the results are hardly to meet the user's demands. According to the current OWL-S,...
The geographic information service applications are getting more and more closely interconnected with the real-time industries and businesses recently. It becomes an urgent problem to gather business information from various industries directly. In this paper, we present an ontology-based dynamic data gathering method of geographic information services, which can extract instant information from MIS...
The MPEG Query Format (MPQF) which MPEG Group is developing is to standardize query interface for XML-based multimedia retrieval systems. MPQF provides query types for Information Retrieval and Data Retrieval over XML Database in the current draft. As more and more multimedia metadata modeled with semantic ontology like RDFS and OWL are stored in the Knowledge Base, there is a requirement for querying...
In this article, we propose a new method TKVM (Teacher's Knowledge Visualization Method) to map school teachers' knowledge by using their school website content. We use then this generated knowledge to create knowledge-driven cartographies. School websites are essential to share information and data between users, but the knowledge contained in these websites are often informal and difficult to locate...
Often in a research community there are several different metadata standards used to describe the same type of objects. In this paper we explore using an RDF/XML (Resource Description Framework) framework to address this issue, and create a flexible, reusable solution that can adapt to new metadata standards. We create a semantic framework that contains multiple metadata views of the objects that...
This paper presents a Capability Ontology (CapOnt) and a rule-based reasoning mechanism, which support service management within adaptable service systems. The ontology concepts comprise capability types, capability parameters and service management functions related to capabilities. Capability parameter values can be defined by constraints on other capability parameters. The service management functions...
The current trends for the future evolution of the Web are without doubt the Semantic Web and Web 2.0. A common perception for these two visions is that they are competing. Nevertheless, it becomes more and more obvious that these two concepts are complementary. Towards this perspective, in this work we introduce an application based on a 3-tier architecture that illustrates the potential for combining...
Data modeling is one of the most important activities in the process of information systems development which is based on domain knowledge in specific area. This paper presents a system for analyzing data model correctness from both syntax and semantic aspect. The system is based on using ontology for domain knowledge representation, transformation of data models and ontology to predicate logic form...
Programming-by-example (PbE) as a technique can only make substantial progress by addressing the open problem commonly known as the Semantic Gap. This gap is the discrepancy between what the user intended by their actions, and how the inference engine generalizes the actions for reuse in a program. The Seahawk/Daggoo PbE system attempts to close this gap in a novel way: by using Semantic Web and Web...
Recently ontologies have drawn much attention from research communities. However, the advantage of using ontologies for knowledge-driven intelligent query answering is yet to be fully explored. In this paper, we examine the use of ontologies for guiding XML query relaxation and propose a practical approach which incorporates WordNet ontology with free software Qexo. Rather than reinventing the wheel,...
With the advent of Web 2.0, RESTful web services are becoming increasingly popular to emphasize the web as platform. There are already many RESTful web services and the number of services is increasing rapidly. Thus, it can be difficult to find specific services using keyword based retrieval. To solve this problem, a retrieval method was developed using semantic technologies based on RESTful web services...
The concept of ontology modeling and engineering has drastically evolved with the emergence of semantic web. Today in a collaborative environment ontologies need to interoperate for efficient data exchange. Due to their deterministic nature, ontologies are unable to capture uncertainty inherent in many real world problems. Efforts have been made to add the dimension of uncertainty by synergizing Bayesian...
By now, XML has reached a wide acceptance as a data exchange format in the Internet, and to make the Semantic Web a reality, such data need to be interpreted with respect to ontologies. In order to provide it, a semantic mapping from the XML format data to the ontology is necessary so that XML format data can be converted to OWL. To accomplish this, we offer a mapping formalism to convert the XML...
Large amount of experts are key asset that universities hold. In order to increase people's awareness of experts and foster collaborative opportunities, it is necessary to help users to locate experts with required expertise. This paper proposes a methodology for ontology-based expertise locator, a Semantic Web application that integrates pieces of relevant expertise information from heterogeneous...
