The method uses semantic Web service language (DAML-S) for external presentation of Web services, while, internally, the services are presented by extralogical axioms and proofs in LL. We use a process calculus to present the composite service formally. The process calculus is attached to the LL inference rules in the style of type theory. Thus the process model for a composite service can be generated directly from the proof. The subtyping rules that are used for semantic reasoning are presented with LL inference figures. We propose a system architecture where the DAML-S translator, the LL theorem prover and the semantic reasoner can operate together to fulfill the task. This architecture has been implemented in Java.","PeriodicalId":135986,"journal":{"name":"Proceedings.

One of the key challenges to enable the broader use of grid services beyond the domain of scientific computing is the ability to perform complex tasks that require the modeling and coordination of the enactment of a number of distributed grid services. Workflow technology is a good candidate for supporting grid service flow. However, traditional workflow is static, thus unable to exploit the dynamic information available in the grid and respond to the dynamic nature of the grid. In this paper, we present an adaptive framework that provides adaptive management of grid service flows. The framework is based on an adaptive grid service flow model and is supported by an event-trigger-rule (ETR) technology that will be used to trigger rules in a distributed fashion to adapt a grid service flow to the dynamic grid environment and the changing requirements of a grid application.","PeriodicalId":135986,"journal":{"name":"Proceedings.

The modification of Web services is a task that entails the modification and compilation of the source code, as well as the deployment of the new version of the Web service in the application server. In this paper, we introduce RAWS (Reflective and Adaptable Web Service), a Web service design model based on a reflective architecture of two levels. RAWS allows both the dynamic modification of the definition and implementation structure of the Web service, and the dynamic modification of the Web service behavior in order to change the existing code or to add new functionalities. All these dynamic modifications are performed directly on the code during execution, with no need to have the Web service source code. RAWS improves Web services adaptability and maintainability, as well as the ability for authorized clients to remotely modify them.","PeriodicalId":135986,"journal":{"name":"Proceedings.

This is particularly true for healthcare applications. Modern non-invasive unobtrusive sensors enable sophisticated monitoring of the human body. As a result of this monitoring a growing amount of elderly people suffering from chronic diseases will benefit from an enhanced quality of life and improved treatment. Healthcare applications process a vast amount of continuously generated data, this has become a serious challenge. Data stream management addresses this problem in general. However, healthcare applications have additional requirements, e.g., flexibility and reliability. As a consequence, we propose the combination of a sophisticated information infrastructure, called hyperdatabase, and data stream management. Hyperdatabases already allow for reliable process management in a peer-to-peer fashion. In this paper, we elaborate the close relation between distributed process management and data stream management. Further, we show that data stream processing can significantly benefit from an infrastructure for reliable process management. We present the architecture of our prototype infrastructure that supports processing of continuous data streams with a high degree of flexibility and reliability.","PeriodicalId":135986,"journal":{"name":"Proceedings.

Global operations, outsourcing, and increasing specialization have all contributed to this trend. One challenge facing the extended enterprise is how to reconnect the information flows and business processes that were disconnected as the enterprise disaggregated. The emergence of web services, service-oriented architectures, and business process modeling and execution standards are helping to address this challenge. Our contention is that the next phase of evolution is the rise of the intelligent enterprise, which is characterized by being able to adapt quickly to changes in its operating environment. The intelligent enterprise monitors its own business processes and its interactions with customers, partners, suppliers, and collaborators; it understands how this information relates to its business objectives; and it acts to control and optimize its operations to meet its business objectives. Decisions are made quickly and accurately to modify business processes on the fly, dynamically allocate resources, or change business partners (e.g., suppliers, service providers) and partnerships (e.g., establish new service level agreements). This talk will describe challenges in managing the business operations of an intelligent enterprise. While a plethora of tools exist for managing the IT infrastructure (servers, storage, and network resources) of the enterprise, there is little systematic support today for the closed loop management and control of business operations. We will describe technology approaches to intelligent business operations management that we are pursuing at HP Labs., the progress we have made, and some open research questions.","PeriodicalId":135986,"journal":{"name":"Proceedings.

Achieving this interoperability requires dynamic discovery of Web services on the basis of their capabilities. The capability of a service can be properly determined by using not only its functional description (or service interface), but also its quality attributes as judged by previous users of the service. We develop a service repository that extends UDDI registries. This repository combines an ontology of attributes with evaluation data. We base our repository on a new query and manipulation language based on DAML. Our language includes support for a rich set of operations, which are needed to maintain an attribute ontology, publish services, rate services, and select services based on their functional attributes as well as evaluations by others. We have implemented our approach and evaluated its practical completeness via a number of key query and manipulation templates.","PeriodicalId":135986,"journal":{"name":"Proceedings.
