Web Services and Automated Planning for Intelligent Calendars

This paper promotes the automated creation of hybrid personal plans, comprising web services and real human activities, to be supported by the next generation of intelligent calendar applications. A prototype work is present-ed, utilizing both atomic web services and composite ones, the latter having been previously generated from a contingent web service composition module, aiming at in-creasing the likelihood of achieving their intended goal. A metric planner generates a plan, giving priority to web service calls over human activities. Then, a scheduler schedules the human activities into the user’s calendar, taking into account the ordering constraints that result from the plan. The resulting schedules substitute human activities with web services, thus increasing the user’s capacity, his free time, as well as the scheduling options. As a proof of concept we present a case study implementation utilizing existing state-of-the-
