Several rule discovery algorithms have the disadvantage to discover too much patterns sometimes obvious, useless or not very interesting to the user. In this paper we propose a new approach for patterns ranking according to their unexpectedness using semantic distance calculated based on a prior background knowledge represented by domain ontology organized as DAG (Directed Acyclic Graph) hierar...

This paper introduces the Model-Driven Hypermedia Development Method (MDHDM). It is a software process model that applies Model-Driven Engineering (MDE) to the generation of hypermedia applications starting from both process models and object oriented conceptual models. The method provides complete guidance for all the phases of the software development lifecycle, from the analysis phase to the...

Competitiveness based on customer interaction is the baseline for strategies such as customization, postponement and customer-driven manufacturing. The emphasis is on the interface between a focal actor and the customer. The approach may however have implications that explicitly influence the suppliers of the focal actor and this is the core theme of customer-driven purchasing. The method for c...

Researchers in many scientific fields make inferences from individuals to larger groups. For many groups however, there is no list of members from which to take a random sample. Respondent-driven sampling (RDS) is a relatively new sampling methodology that circumvents this difficulty by using the social networks of the groups under study. The RDS method has been shown to provide unbiased estima...

We present a testing framework using a compositional approach to generate and execute test cases. Test cases are generated and combined with respect to a partial specification expressed as a set of requirements and elementary test cases. These approach and framework are supported by a prototype tool presented here. The framework is presented here in its LTL-like and regular expressions applicat...

Model Driven Architecture (MDA) design approach proposes to separate design into two stages: implementation independent stage then an implementation-dependent one. This improves the reusability, the reusability, the standability, the maintainability, etc. Here we show how MDA can be augmented using a formal refinement approach: B method. Doing so enables to gradually refine the development from...

Image annotation is a promising approach to bridging the semantic gap between low-level features and high-level concepts, and it can avoid the heavy manual labor. Most existing automatic image annotation approaches are based on supervised learning. They often encounter several problems, such as insufficiency of training data, lack of ability in dealing with new concept, and a limited number of ...
