With the increasing number of Web services, the Semantic Web research community is moving toward enhancing procedures so that clients may effectively discover appropriate Web services that maximally satisfy not only functional but also non-functional requirements. Using purely syntactic approaches to discover Web services has limited efficiency. Therefore, semantic matchmaking registries can play...
Many educational and training institutions acquired proprietary e-Learning systems which are tailored-made and difficult to reuse in the development process of new systems. This paper aims to look into the issue of reusability of the functionalities in the e-Learning domain. The functionalities that span across many e-Learning systems (common functionalities) can be built as reusable components by...
Abstract Mobile technology is widely used in recent times, where the user access the Web service at any time in any place. Challenges at this point are summarized in how we can discover more relevant Web services for mobile user requests. Many of research handled this point dependent on user requirement and quality standard of Web services; however, this matchmaking returns a service that is not completely...
The Semantic Web Services (SWS) technology is used to describe the Web services' capabilities and content in a computer-interpretable language and improve the quality of existing tasks, such as Web Services discovery, invocation, composition and monitoring. This paper addresses the topic of defining a knowledge based system for representing Semantic Web Service ontologies according to the WSMO-Lite...
With the greater number of Web Services (WSs) available on the internet, searching the appropriate WS that fulfills the user needs has become a major challenge. In this paper, we propose a Goal-based framework for Web Services (WSs) discovery. The framework employs matching algorithms and allows searching through a set of Semantic Web Services (SWS)s in order to find the most suitable WS that matches...
Nowadays, e-government has emerged as a government policy to improve the quality and efficiency of public administrations. In order to improve government-citizen interactions, the government agencies are providing a wide spectrum of online services. However, a single service may not be able to serve citizens' needs, but a combination of web services can serve the purpose. It is an important task to...
With the increasing adoption of Web Services and service-oriented computing paradigm, there is a growing need for efficient mechanism for Web Service discovery. The current semantic matchmaking algorithms are mainly based on the comparison of inputs and outputs of the service request and advertised service. Here reducing the service discovery time and increasing the quality of discovery are the key...
The learner modeling is a cornerstone of the personalized interaction in any Technology Enhanced Learning (TEL). Based on ontology's, the development of the Semantic Web offers new opportunities and challenges in the design of a new generation of adaptive systems, It's in this context that is situated the scope of our research works, with the aim of integrating a new modeling vision and learner pattern...
Additively to the emergence of wireless networking, high technology and reliability of mobile devices have enabled the widespread use of mobile computing. Currently, this last is in vogue and booming. Today, the combination of mobile networks with Web Services called "Mobile Web Service", opening a promising horizon for the economy. They offer (Mobile Web Service) new personalized services...
With the rapid growth of Web services, service discovery becomes an important and difficult issue. Traditional UDDI-based and WSDL-based methods of service discovery have low precision, and semantic-based service discovery methods are usually inefficient and time-consuming. We observe that social annotations can optimize both precision and efficiency of service discovery. In this paper, we propose...
In our work we describe an approach for automated and approximate evaluation of character based answers in computer-based tests. Cloze exercises (‘fill-in-the-blank’) are error-prone to a variety of potential error sources and are subject to syntactic and semantic ambiguities. Our approach combines string similarity measurements with semantic word analysis to render this type of computer-based exercise...
Web service discovery is an important operation in Web service architecture, this paper aims to cluster the Web services before Web service discovery based on OWL-S language. In this paper, Web service ontology is defined. We use Web service function and progress to calculate similarity. Petri net is used to describe Web service process. The Web service similarity is based on an accurate concept semantic...
Web services are software components developed to simplify machine-to-machine interaction over the Web. Many researches are targeted towards Web service standardization, and these efforts have significantly contributed towards improving functionality of Service Oriented Architecture (SOA). However, there are number of issues yet to be resolved. Among them, one of the major challenges is the standardization...
Currently there exist many kinds of semantic Web Service models on the internet. They are heterogeneous so that it is hard to understand and interoperate each other. In this paper, we study several mainstream semantic Web Service models, and extract meta-models for each from the perspective of semantic Web Service discovery. Based on this, we propose the universal meta-model for semantic Web Service...
The increasing growth in popularity of Web services has made it difficult for business users to fully benefit from these services if they remain specified at the software level. The introduction of intentional services is an alternative for bridging the gap between low level, technical software-service descriptions and high level, strategic expressions of business needs for services. The current Web...
Since the reusing and arranging of available Web services have been raised, the amount of infrastructure strategies based on Service Oriented architecture (SOA) is increasing. Hence, a rich Semantic Web service description is needed to achieve an automated Web service discovery, composition and invocation. On the other hand, the acceptance of Semantic Web service is still decelerating because of its...
Web services are the most important event in distributed computing today and have achieved great popularity among software developers. A critical step in the process of developing applications based on web services is web service discovery, i.e., the identification of existing web services that can potentially be used in the context of a new web application. We have proposed a novel method based on...
Recently semantic technology have been popular in the spatial information area, but this semantic ability can only support for its own system, cannot fulfils other system's need. So a semantic service middleware taking place of original semantic system, will give a free semantic service without change the system's internal structure.
In today's world of web, everybody desires different types of E-services from the internet, which is a massive storehouse of information, and on demand produces required services in front of the consumer. This brings revolution to the civilization of mankind. Hundreds of researchers are working on easy access of web services. When a user searches web for specific information, the search engine produces...
With the development of web service, the number of applications based on web service is increasing rapidly in recent years. More and more attention has been drawn to web service because of its convenience and platform-independence. In the few past years, UDDI is a common mechanism of publishing services in industrial applications. However, there are still no official standards which are recommended...
