Abstract
Résumé (Français et/ou Anglais) : This thesis lies within the scope of work relating to the Semantic web Services, from the point of view of the complementarity and the coevolution of two aspects of the Web, services and semantics in the tourist domain. In order to improve the search and reservation experience of the user, we are particularly interested in the use of the Linked Open Data in order to facilitate the access to the offer of tourist products and services present on the Web, and this in a useful way, informative and enriching for the user on one hand and compromise ensuring a flexible and dynamic composition of the Semantic Services Web relating to the reservation of their stays on the other hand. In our work we show how the semantic links between concepts resulting from the tourist graph Web can be used together for finding the better Semantic Web Services in order to solve the user'semantic request (expressed in SPARQL) and explain our method of dynamic composition based dependence graph where the nodes of the generated graph are related to the cluster of services (the Iso-functional Process models, possibly being useful in replanning phase of the breakdown of a component in the generated workflow) and the transitions are the semantic links representing the services'interdependence. Then, we propose an incremental algorithm that extracts the relevant atomic processes for the composition by sorting the equivalents Process Models according to a definite similarity criterion thus making it possible to optimize the size of the initial graph in terms of the number of their atomic processes (an indivisible operation) and to deduce the final and optimal composition plan using the matrices theories thus representing the desired dynamic package. The results of experiments show that they are able to ensure scalability for more complex problems.
