Despite significant research and development efforts, the vision of the Semantic Web yielding to a Web of Data has not yet become reality. Even though initiatives such as Linking Open Data gained traction recently, the Web of Data is still clearly outpaced by the growth of the traditional, document-based Web. Instead of releasing data in the form of RDF, many publishers choose to publish their data...
RESTful Web services are an increasingly popular way for companies to expose their data on the Web. On the other hand, the Linked Open Data initiative is gaining traction recently. Since REST's principles align well with those of Linked Data, there is an increasing interest in the relationship of the two. Nevertheless, in practice they still largely remain separated, creating islands of data instead...
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...
At present, vast amounts of data resources are provided on the internet. Therefore, how to improve the effective knowledge acquiring has already been the main concern of the industry. Basing on the analysis of people's demand of information, this paper introduces OWL-S and semantic relations of the paradigmatic and the syntagmatic, and proposes a knowledge sharing model. Furthermore, knowledge matching...
Wireless Sensor Networks (WSNs) are deployed for a wide range of applications to sense closely and collectively the environment in which they are placed. To provide services related to sensed data from a WSN to a user through Internet as per requirements has a great technological and commercial potential. For this it is necessary that a suitable WSN is quickly discovered automatically for the user...
Today, Internet is a huge database which comprises of a large number of Web sites, search engines and other information. Due to the unstructured and semi structured data in the web pages, it is a challenging task for researchers to make a relevant and efficient search in warehouse of such type of database. Ontology may be a good mechanism for achieving this goal and Web Mining technique may be used...
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...
The Internet is the largest information repository. Most information retrieval systems are based on the premise that users know the keywords for searching subjects. Web services provide a suitable technical framework for making business processes accessible within enterprises and across enterprises, so that they have promoted a new paradigm of a business process which is called the service-oriented...
Web service is expected to be the key technology of implementing SOA solution on the Internet. However, it is more and more difficult to find suitable services with the increase in Web services. Service Network (SN), which is a semantic relation based Web service infrastructure, is proposed to bridge the gap between service providers and service consumers. In this paper, we discuss the whole process...
With the development of Internet and information sharing, semantic web attracts many re-searchers' attention in computer field. Web service composition is an important technology in domain of Web service. As integrated solution for realizing the vision of the next generation of the web, semantic web services combine the semantic web technology with web service technology, and thus enable automated...
Recently, semantic Web services have become a rising application over the internet. At the same time, security and trustworthy becomes extremely important. But there is no effective access control method for semantic Web services to provide trusted Web services. This paper studies a new access control method for semantic Web services based on trust management (SWS-TMBAC). This method combines the...
With the quick increase of web services on the Internet, how to discover proper services efficiently in a large number of web services becomes more and more difficult. Services discovery efficiency can be improved greatly after services have been classified well, so an algorithm of clustering services which uses graph theory and a corresponding algorithm of discover services are proposed in this paper...
Web service is one of SOA applications in the Internet. Web service workflow is a set of Web services that are executed in some sequence. In this way, it will greatly improve the reuse of Web Services. As well as to enhance reuse of workflow, this paper describes, finds and composes workflow by ontology. And adds a translator from the Owl-S of workflow to BPEL4WS on the base of traditional workflow...
Reengineering the web service composition is an immediate need in the current Internet scenario as it experiences a spectacular increase in the number of available web services. To satisfy the user query, composition of web services is required which involves semantic matching and syntactic mapping. This paper proposes a technique which extends the semantic matching with evaluation of QoS properties...
The Web Service has been extended to the back-end database. In this paper, we propose a novel method of user behavior analysis in semantic network. We use the weight value to analyze and record user behavior and then check user behavior record with the signatures which are generated by the Intrusion Detection System (IDS). If a user record matches with signatures, the system will pass the record to...
Web service is expected to be the key technology of implementing SOA solution on the Internet. However, as Web services proliferate, it is more and more difficult to find suitable services and further compose them into complex applications automatically. In this paper, a novel service infrastructure named Service Network (SN), which is constructed on the basis of service relations, is proposed to...
Web services are becoming de facto a standard for data exchanging, since they provide a clear way to express and access information throughout the Internet. Sometimes, one service alone is not able to perform a certain task, and it might be necessary to compose two or more services in order to accomplish that task. In this context, semantic web services play an essential role, since they provide a...
Advances in Internet and software technology play increasing roles in creating work environments and online services that impact our everyday living. Web service computing paradigm has revolutionized how these software applications can be developed rapidly and reliably by employing available services available in standard forms across the web. Automatic composition of Web services is necessary and...
Spatial data infrastructures are currently being set up within regions, countries and across national border. In SDIs, the data sharing is replaced by the service sharing gradually. Many geospatial services are provided on the Internet, WPS-based remote sensing image processing is a special type in these services, it can differ widely in their functionality. Current (keyword-based) approaches to service...
With the number of services published on the Internet growing at an explosive speed, it is difficult for service requesters to discover satisfactory web services. The reason for this phenomenon is that traditional service organization mode lacks semantic information metadata, which results in low discovery effect. In this paper, we firstly give a service description model and then present an overall...
