Designing web services-based processes (WSP) requires striking the balance between intuitive and easy to understand process representation for the interactive domain user and consolidated formal mathematical specification. An easy to understand process ...

Many Web service standards of orchestration and choreography are designed to reduce their inherent complexity of composing Web services. Existing standards all remain at the descriptive level, without providing any formal semantics and method for ...

Recommendation systems have proven to be useful in various application domains. However, current solutions are usually ad-hoc systems which are tightly-coupled with the application domain. We present the IC-Service, a recommendation service that can be ...

Message Exchange Pattern (MEP) is a challenging problem in the interaction of Web services. However, by means of the non-formal descriptions, such as in SOAP and WSDL, it is impossible to conduct precise definition of MEPs, thus leading to potential ...

To fight community abuse, we introduce in this paper a set of simple, yet powerful, trust protocols, aimed at enforcing on a P2P network a boolean Code of Conduct verifiable by the network agents themselves. Having a boolean Code of Conduct which honest ...

This paper presents the design of SNet system, which is a P2P overlay for Semantic Web Services discovery. SNet differs from previous P2P Web Services discovery systems in that it supports complex search with its locality-preserving feature based on ...

Content-based implicit user modeling techniques usually employ a traditional term vector as a representation of the user's interest. However, due to the problem of dimensionality in the vector space model, a simple term vector is not a sufficient ...

In current practice, Web applications are tightly coupled with the platforms that a particular service provider intends to support and the execution scenario envisioned at the design time. The resulting applications do not adapt well to all clients and ...

The emergence of small, resource-constrained, and highly mobile computing platforms presents numerous challenges for software developers. We propose an adaptive middleware architecture for mobile phones that supports the development of interactive ...

The digitalization of historical text documents as a basis of data mining and information retrieval for the purpose of progress in the history sciences is urgently needed. We present a novel, specialist XML tool-suite supporting the working historian in ...

Several previous works have proven that there is no way of guaranteeing a snapshot isolation level in symmetrical replicated database systems without blocking transactions when they are started. As a result of this, the generalized snapshot isolation (...

This paper presents a federated directory system called WS-Dir, which allows registration and discovery of semantic web services. The system is designed and implemented as a federation: directory services form its atomic units, and the federation ...
