We have created a web agent for collecting Call for Papers (CFP) announcements. Our web agent obtains CFP announcements from websites or from mailbox. The most important information is extracted and published on our own special website in a user and machine readable way. One of the most important problems is event classification, categorization and clustering. In this paper we describe unsupervised...
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...
The following topics are dealt with: database technology; Web information management; Web information system security; quality assurance; Web information mining; information retrieval; Web service; semantic Web; deep Web technology; ontology; and electronic government technology.
Recent years have seen a huge increase in the amount of publicly-available information relevant to drug discovery, including online databases of compound and bioassay information; scholarly publications linking compounds with genes, targets and diseases; and predictive models that can suggest new links between compounds, genes, targets and diseases. However, there is a lack of tools and methods to...
Most of today's business processes are complex and consist of more than one party or single step procedures. In the Web, this is reflected by the existence of billions of Web sites, which may be regarded as complex processes, and on the other side only a few thousands of publicly available WSDL files that present single services. The availability of semantic descriptions of services and processes...
The Semantic Web has made possible the use of the Internet to extract useful content, a task that could necessitate an infrastructure across the Web. With Hadoop, a free implementation of the MapReduce programming paradigm created by Google, we can treat these data reliably over hundreds of servers. This article describes how the Apriori algorithm was adapted to MapReduce in the search for relations...
Increasingly, application developers seek the ability to search for existing Web services within large Internet-based repositories. The goal is to retrieve services that match the user's requirements in a fast and efficient way. It is necessary to explore an approach of service semantic relationship discovery to enhance search engine results with a list of related services for each hit. In this paper,...
Supply chains coordination plays an important role in supply chains system. This paper mainly studied the problem of mining service set to efficiently select and integrate Semantic Web Services (SWS) in supply chain for improving supply chains coordination. First, the method of generating SWS based service supply chain were introduced. Second, hypergraph-based matrix representation for service supply...
Semantic Web services have been employed in a wide range of applications and have become a key technology in developing business operations on the Web. However, heterogeneity is a major problem of the current semantic Web service technologies. In particular, semantic Web services described by different description languages cannot work together. For example, a Web service described by OWL-S cannot...
Semantic Web Services discovery and composition: paths along workflows Web Services allow the composition of new services on top of existing, partial ones. Using standard languages, Semantic Web Services can provide the description of their input parameters and preconditions for execution, as well as the output and effects of their execution. The availability of such descriptions demand the investigation...
Automating Web service composition is a challenging area of service oriented computing, requiring progress on a number of issues concerning the automation of control flow, the alignment of data flow, verification, execution monitoring, etc. In this paper, we focus on aligning data flow in semantic Web service composition to ensure the robustness when executing the composed service by preventing any...
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...
In this paper, we present a framework to facilitate reputation-based service selection with reputation management, which has three key features. First, we use a structured overlay network as the decentralized service repository system for improved efficiency. Second, we propose an adaptive QoS-aware service discovery approach. Then, we present a service-oriented distributed reputation assessment algorithm...
The traditional syntactic service matchmaking is lack of semantic information with machine understandable, so it can not achieve intelligent service discovery. In this paper, the fuzzy nature of matchmaking is considered, and the conceptions of linguistic variables in fuzzy logics are introduced into service matchmaker. The matchmaking linguistic variables and the fuzzy relationship matrix are defined,...
Semantic Web Service (SWS) enrich Web Service technology with formal, ontology-based descriptions of service functionalities and capabilities at the semantic level, thus enabling semantic-based discovery, composition, dynamic binding and orchestration.Several solutions were proposed for the specification of the Semantic Web Services, in this paper, we propose a reverse engineering based approach to...
In the service collaboration field, there exists the need to combine two or more services together to fulfill a complex goal. Though service composition is an active research field, most of solutions are focused on Web services and lack of the consideration for business-level collaboration. In this paper we present a discovery architecture that supports business-level service composition. In our architecture,...
Most of the work on automated Web service composition has focused so far on composition of stateful Web services. This level of composition so called ldquoProcess Levelrdquo considers Web services with their internal and complex behaviours. At process level formal models such as State Transition Systems (STS from now) or Interface Automata are the most appropriate models to represent the internal...
With the advance of Semantic Web, the adoption of Semantic Web has been regarded as the most promising way to improve the recall rate and precision rate of service discovery. However, Semantic Web Service discovery (SWS) is essentially not used on a large scale in real business world due to its time consuming performance and weak support for the QoS-based discovery. In order to solve these problems,...
The emerging Web service technologies have received increasing attention in both industry and academic communities. The interoperability it promised has made it more welcome than other integration technologies. However, Web services may not be able to interact with one another directly due to interface mismatches. It happens when the service consumer and service provider have different message signatures...
The aim of service discovery is to discover services based on preferences given by service consumers. Many approaches are using keyword based syntactic methods and recent approaches are using semantic Web technology to enhance service discovery. Traditional service discovery mechanism acts like a black box which processes input and gives output. Results of service discovery are not based on current...
