Service Oriented Computing is a paradigm for developing software systems as the composition of a number of services. Services are loosely coupled entities, can be dynamically published, discovered and invoked over a network. The engineering of such systems presents novel challenges, mostly due to the dynamicity and distributed nature of service-based applications. In this paper, we focus on the...

Business processes are designed to execute strategies that aim at achieving organisational goals. During the last decade, several methods have been proposed that prescribe the use of goal-oriented requirements engineering techniques for supporting different business process management activities, in particular business process modelling. The integration of goal modelling and business process mo...

During the last decade, research in the field of business process management (BPM) has focused on the design, modeling, execution, monitoring, and optimization of business processes. What has been neglected, however, is the provision of knowledge workers and decision makers with needed information when performing knowledge-intensive business processes such as product engineering, customer suppo...

A core motivation of service-oriented execution of business processes is the opportunity to reduce costs by outsourcing certain tasks to third-party service providers. For legal or economic reasons, it might be undesirable that delicate information (e. g., customer data, trade secrets, or financial details) “leak” to the involved third parties. The absence of such leaks — called noninterference...

This paper investigates how to automatically create a dialogue control component of a listening agent to reduce the current high cost of manually creating such components. We collected a large number of listening-oriented dialogues with their user satisfaction ratings and used them to create a dialogue control component using partially observable Markov decision processes (POMDPs), which can le...

The need of retrieving 3D models is constantly emerging. To improve the performance of a shape-based 3D model retrieval system, an approach is introduced to classify and retrieve 3D model by integrating shape features and semantic information. First, a new type of shape feature based on 2D views (called ZA) is proposed. Then we use Gaussian processes as supervised learning to mode the mapping f...

Information Systems (IS) has become one of the most valuable assets of modern organizations where they play a critical role in supporting operational and decision processes. Nevertheless, despite the large part of organizations resources invested in information technology, development of information systems (IS) faces many problems recognized in the term “software crisis”. In order to reduce th...

The goal of the GOODSTEP project is to enhance and improve the functionality of a fully object-oriented database management system to yield a platform suited for applications such as Software Development Environments SDEs. The baseline of the project is the O 2 database management system DBMS. The O 2 DBMS already includes many of the features required by SDEs. The project has identifed enhance...

Over the past decade, the policy and scholarly communities have increasingly recognized the need for governance of water-related issues at the global level. There has been major progress in the achievement of international goals related to the provision of basic water and some progress on sanitation services. However, the water challenge is much broader than securing supply. Doubts have been ra...

The integration of Business Process Management (BPM), Service Oriented Computing (SOC) and Model Driven Development (MDD) paradigms to improve the development of services oriented solutions from business models is nowadays in the spotlight. Organizations wanting to remain competitive despite the constant changes in their business are paying more attention to their business processes and its bas...
