In this paper we consider the problem of sharing the costs of multicast transmissions in ad hoc wireless networks. Assuming that the receiving users are selfish, we provide strategy- proof mechanisms that are either optimally budget balanced or efficient for the case in which the distance-power gradient α =1 or the stations belong to a ne-dimensional(More)
Enriching business process models with semantic tags taken from an ontology has become a crucial necessity in service provisioning, integration and composition. In this paper we propose to represent semantically labelled business processes as part of a knowledge base that formalises: business process structure, business domains, and a set of criteria(More)
This paper addresses the problem of predicting the outcome of an ongoing case of a business process based on event logs. In this setting, the outcome of a case may refer for example to the achievement of a performance objective or the fulfillment of a compliance rule upon completion of the case. Given a log consisting of traces of completed cases, given a(More)
Modern information systems that support complex business processes generally maintain significant amounts of process execution data, particularly records of events corresponding to the execution of activities (event logs). In this paper, we present an approach to analyze such event logs in order to predictively monitor business constraints during business(More)
Enriching business process models with semantic annotations taken from an ontology has become a crucial necessity both in service provisioning, integration and composition, and in business processes management. In our work we represent semantically annotated business processes as part of an OWL knowledge base that formalises the business process structure,(More)
Business processes are often implemented by means of software systems which expose them to the user as an externally accessible Web application. This paper describes a technique for recovering business processes by dynamic analysis of the Web applications which ex-pose them. This approach does not require full access to internal software artifacts, such as(More)
It is nowadays well-established that the construction of quality domain ontologies benefits from the involvement in the modelling process of more actors, possibly having different roles and skills. To be effective, the collaboration between these actors has to be fostered, enabling each of them to actively and readily participate to the development of the(More)
