The Relationship

This chapter introduces applications of Web services in bioinformatics as a specialized application of peer-to-peer (P2P) computing. It explains the relationship between P2P and applications of Web service in bioinformatics, states some problems faced in current bioinformatics tools, and describes the mechanism of Web services framework. It then argues that Web services framework can help to address those problems, and gives a methodology to solve the problems in terms of composition, integration, automation, and discovery.

Active Xml

Active XML (AXML) provides an elegant platform to integrate the power of XML, Web services and Peer to Peer (P2P) paradigms by allowing (active) Web service calls to be embedded within XML documents. In this chapter, the authors present some interesting aspects encountered while investigating a transactional framework for AXML systems. They present an integrated locking protocol for the scenario where the structure of both data and transactions are nested. They show how to construct the undo operations dynamically, and outline an algorithm to compute a correct optimum undo order in the presence of nesting and parallelism. Finally, to overcome the inherent problem of peer disconnection, the authors propose an innovative solution based on ”chaining” the active peers for early detection and recovery from peer disconnection.

The paper mainly researched the game actions among partners in complex interactions supported by Web Service. It studied web service provider’s implementation decision satisfied with perfect Bayesian equilibrium thus results a controllable equilibrium route in voluntary implementation. It also contributes to the problem of voluntary implementation when the planner is also a player and finds out the full characterization of it. So the implementation mechanism can always get the reconciliation of web service, which is able to effectively facilitate dynamic interactions among trading partners in a peer to peer mode.

The Relationship

By analyzing the existing Web service composition，a automatic composition method of Web Service based on Petri net was been proposed. This paper primarily extended the Petri net’s tokens, which been expressed as the parameters of atomic services (the services can not be decomposed), as a model for Web services. Then the improved Web service composition method was used to compose the atomic services, making them flowing in the Petri net in accordance with the relationship between the composition of atomic services, and verify the correctness of the service. Finally a specific example was used to analyze and realize the service modeling and automatic composition process of Web service.

A web service is a software function provided at a network address over the web or the cloud. Conventional web service is described by WSDL. As for the conventional web services, it has problems of discovering and selecting the most suitable web service. Semantic web service can solve these problems, and it is described by OWL-S. In this paper, we propose a method of automatic generation of documents from WSDL to OWL-S. To accomplish this, we first translate XML document to OWL document through the relationship between XML Schema and the ontology. We use a mapping rule from XML Schema to Schema tree and Element tree. As for the WSDL document is written by XML. And OWL-S document is written by OWL. We translate WSDL document to OWL-S document based on mapping between XML document and OWL document. At present, most of web service is described by WSDL. According to this method, we can not only translate from WSDL document to OWL-S document easily, but also make the generation more efficient. Thus, we provide support for extensive of web services and service composition and discovery. Through the use of an example, the paper verifies the method is feasible and effective.

The I\O file system Read\Write operations are considered the most significant characteristics. Where, many researchers focus on their works on how to decrease the response time of I\O file system read\write operations. However, most articles concentrate on how to read\write content of the file in parallelism manner. Here in this paper, the author considers the parallelizing Read\Write whole file bytes not only its contents. A case study has been applied in order to make the idea more clear. It talks about two techniques of uploading\downloading files via Web Service. The first one is a traditional way where the files uploaded and downloaded serially. While the second one is uploaded\ downloaded files using Java thread in order to simulate parallelism technique. Java Netbeans 8.0.2 have been used as a programming environment to implement the Download\Upload files through Web Services. Validation results are also presented via using Mat-lab platform as benchmarks. The visualized figures of validation results are clearly clarifying that the second technique shows better response time in comparison to the traditional way.

Recently, web services have presented a new and evolving model for constructing the distributed system. The meteoric growth of the Web over the last few years proves the efficacy of using simple protocols over the Internet as the basis for a large number of web services and applications. Web service is a modern technology of web, which can be defined as software applications with a programmatic interface based on Internet protocol. Web services became common in the applications of the web by the help of Universal, Description, Discovery and Integration; Web Service Description Language and Simple Object Access Protocol. The architecture of web services refers to a collection of conceptual components in which common sets of standard can be defined among interoperating components. Nevertheless, the existing Web service's architecture is not impervious to some challenges, such as security problems, and the quality of services. Against this backdrop, the present study will provide an overview of these issues. Therefore, it aims to propose web services architecture model to support distributed system in terms of application and issues.

Concise Description

One of the key challenges of the Service Oriented Architecture is the discovery of relevant services for a given task. In Semantic Web Services, service discovery is generally achieved by using the service profile ontology of OWL-S. Profile of a service is a derived, concise description and not a functional part of the semantic web service. There is no schema present in the service profile to describe the input, output (IO), and the IOs in the service profile are not always annotated with ontology concepts, whereas the process model has such a schema to describe the IOs which are always annotated with ontology concepts. In this paper, we propose a complementary sophisticated matchmaking approach which uses the concrete process model ontology of OWL-S instead of the concise service profile ontology. Empirical analysis shows that high precision and recall can be achieved by using the process model-based service discovery.
