A Middle-Ware for the Automated Composition and Invocation of Semantic Web Services Based on Temporal HTN Planning Techniques

This work presents a middle-ware able to translate OWL-S web services descriptions into a temporal HTN domain in order to automatically compose and execute sequences of web service invocations, including parallel branches and complex synchronizations, based on the combination of HTN planning and temporal reasoning techniques.

Handling fuzzy temporal constraints in a planning environment

Abstract An interleaved integration of the planning and scheduling process is presented with the idea of including soft temporal constraints in a partial order planner that is being used as the core module of an intelligent decision support system for the design forest fire fighting plans. These soft temporal constraints have been defined through fuzzy sets. This representation allows us a flexible representation and handling of temporal information. The scheduler model consists of a fuzzy temporal constraints network whose main goal is the consistency checking of the network associated to each partial order plan. Moreover, we present a model of estimating this consistency, and show the monitoring and rescheduling capabilities of the system. The resulting approach is able to tackle problems with ill defined knowledge, to obtain plans that are approximately consistent and to adapt the execution of plans to unexpected delays.

Cities that offer a customized and personalized tourist experience to each and every visitor: the smartourism project

This paper presents an approach of HTN planning technology devoted to design personalized visits to a city depending on the tourist attractions of the city, the preferences of the visitor, his/her budget, available time and even his/her disabilities. Therefore, the city intelligently adapts to every potential visitor and offer them its best choice becoming a customized tourist experience because it has been exclusively designed for them.
