The need still exists for automatic WS composition to solve the problems within various domains. Many research efforts have been conducted in automatic WS composition using different techniques. In the context of the AI planning technique, the work of Hatzi et al. The approach is based on transforming the WS composition problem into a planning problem that is encoded in PDDL and solved by external planners. The produced composite services are transformed back to OWL-S. The work of Zou et al. A WS composition planning problem is subsequently fed into an AI planner to automatically find a composition plan corresponding to the given composition request. The work of Puttonen et al. The framework aims to extract the planning actions from the OWL-S service descriptions and create a mapping from each action to convert the acquired solution plans into composite OWL-S processes. The results are intended to reduce the workload of developing semantic WS descriptions and enable automatic composition and deployment of workflow descriptions.

By adding constraints over aspects that the Seeker is interested in, the query can be used to filter out irrelevant advertisements. There are two kinds of queries that can be defined: The persistent query is a query that will remain valid for a length of time defined by the Seeker itself. The Host immediately returns matched advertisements that are currently present in the repository.

Within the validity period of the query, whenever a matching advertisement is added to the repository or an advertisement is modified so that it becomes a match , the Host will notify the Seeker with a new set of matched advertisements including those that have been changed or have been added.

A user study of semantic Web services matching and composition Inferring similarity between Web services is a fundamental construct for service matching and composition. However, there is little evidence of how humans perceive similarity between services, a crucial knowledge for designing usable and practical service matching and composition algorithms.

In this study we have experimented with users to define and evaluate a model for service similarity in the context of semantic Web services. Our findings show that humans take a complex and sophisticated approach towards service similarity, which is more fine-grained than suggested by theoretical models of service similarity, such as logic-based approaches.

Finally, we describe an application of a Web service search engine that implements our model. Area project Service orientation is an emerging software engineering paradigm that emphasizes the reuse of existing and distributed software services.

Web service composition is a mechanism for creating new web services by reusing existing ones. In order to compose a web service, the right primitive services have to be discovered. A matchmaking technique enables discovering these services.

It is widely recognised that one of the key elements for the automated composition of Web ser- vices is semantics i. However Web services described at capability level need a formal context to per- form the automated composition of Web services. Moreover we introduce the composition process as a matchmaking of domains and solve the latter problem according to a formal model i. Introduction An important vision of service oriented computing is to enable dynamic service binding i.

SOA Service Oriented Architecture based Web Service provides a suitable technical foundation for loosely coupled and reusable software components. However there is still some work to be done to appropriately support dy- namic and automated tasks such as discovery, selection and composition. Indeed the automation of the latter tasks re- quires some knowledge about Web services: These requirements may be cov- ered by means of a semantic model of Web services i.

The semantic feature of Web services allows not only a high level of semantic description but also different kinds of inference in order to ease automatic discovery, selection, composition and reasoning. Towards the challenge of Web service composition or the process to form new value-added Web services, the TLB Architecture focuses on three main levels. The sec- ond unit i. In this level Web services can be ex- ecuted in a simple request-response step.

To fully fulfill the modularity and loosely coupled characteristics of P2P semantic mapping paradigm proposed in our previous work[1], a mapping creation method based on semantic discovery is presented to avoid a time-consuming and labor-intensive artificial mapping creation process. This method creates semantic mapping between peer node models by establishing the semantic relations between elements from different peer node models.

Semantic relative candidates are captured through the correspondence semantic matching process including concepts matching process, attributes matching process, relations matching process, concepts and relations matching process, and concepts and attributes matching process.

Since then, it hasbeen evolving, and now it is used by businesses, governments and individuals to make their data accessible through theInternet. A large portion of accessible data is only understandable for human beings and a few special purpose applications. These heterogeneous data are used to create more and more complicated applications.

Learning User Profiles from Text for Personalized Information Access Abstract Advances in the Internet and the creation of huge stores of digitized text have opened the gateway to a deluge of information that is difficult to navigate. Although the information is widely available, exploring Web sites and finding information relevant to a user’s interests is a challenging task. The first obstacle is research, where you must first identify the appropriate information sources and then retrieve the relevant data.

Then, you have to sort through this data to filter out the unfocused and unimportant information. Lastly, in order for the information to be truly useful, you must take the time to figure out how to organize and abstract it in a manner that is easy to understand and analyze.

Semantic matching represents a fundamental technique in many applications in areas such as resource discovery, data integration, data migration, query translation, peer to peer networks, agent communication, schema and ontology merging. It using is also being investigated in other areas such as event processing. In fact, it has been proposed as a valid solution to the semantic heterogeneity problem, namely managing the diversity in knowledge.

Interoperability among people of different cultures and languages, having different viewpoints and using different terminology has always been a huge problem. Especially with the advent of the Web and the consequential information explosion, the problem seems to be emphasized. People face the concrete problem to retrieve, disambiguate and integrate information coming from a wide variety of sources.

Semantic web service composition is about finding services from a repository that are able to accomplish a specified task if executed. The task is defined in a form of a composition request which contains a set of available input parameters and a set of wanted output parameters. Instead of the parameter values, concepts from an ontology describing their semantics are passed to the composition engine.

The parameters of the services in the repository the composer works on are semantically annotated in the same way as the parameters in the request.

The Internet is changing the way businesses operate. Organizations are using the Web to deliver their goods and services, to find trading partners, and to link their existing maybe legacy applications to other applications. On the other hand, e-business as an emerging concept is also impacting software – plications, the everyday services landscape, and the way we do things in almost each domain of our life.

There is already a body of experience accumulated to demonstrate the difference between just having an online presence and using the Web as a stra- gic and functional medium in e-business-to-business interaction B2B as well as marketplaces. Finally, the emerging Semantic Web paradigm promises to annotate Web artifacts to enable automated reasoning about them.

When applied to e-services, the paradigm hopes to provide substantial automation for activities such as discovery, invocation, assembly, and monitoring of e-services. But much work remains to be done before realizing this vision. Jos de Bruijn Language: Semantic Web services promise to automate tasks such as discovery, mediation, selection, composition, and invocation of services, enabling fully flexible automated e-business. Their usage, however, still requires a significant amount of human intervention due to the lack of support for a machine-processable description.

In this book, Jos de Bruijn and his coauthors lay the foundations for understanding the requirements that shape the description of the various aspects related to Semantic Web services, such as the static background knowledge in the form of ontologies, the functional description of the service, and the behavioral description of the service. They introduce the Web Service Modeling Language WSML , which provides means for describing the functionality and behavior of Web services, as well as the underlying business knowledge, in the form of ontologies, with a conceptual grounding in the Web Service Modeling Ontology.

Academic and industrial researchers as well as professionals will find a comprehensive overview of the concepts and challenges in the area of Semantic Web services, the Web Services Modeling Language and its relation to the Web Services Modeling Ontology, and an in-depth treatment of both enabling technologies and theoretical foundations.
