The fourth issue of LNCS Transactions on Petri Nets and Other Models of Concurrency (ToPNoC) contains revised and extended versions of a selection of the best papers from the workshops held at the 30th International Conference on Application and Theory of Petri Nets and Other Models of Concurrency, Paris, France, June 22¿26, 2009, and from the 10th Workshop and Tutorial on Practical Use of Coloured Petri Nets and the CPN Tools, Aarhus, Denmark, October 19¿22, 2009.@en

Many Web applications have offered personalization and adaptation as their features in order to provide personalized services to their users. The user profiles are gathered independently by these applications often through an explicit dialogue with the user. As a result, the users have to go through a similar elicitation process multiple times, that is, providing similar information that is used to build the user profiles to different applications. In the springtime of mashup applications, we observe the importance of considering user information in order to make the presented content more relevant to the user. For this purpose, it is necessary to have a platform/ framework that enables components in the mashup to reuse and exchange user profiles. In this paper, we present the Morpho framework that elicits, enhances, and transforms a user profile from one application to another application in a mashup environment. It deals with semantic and syntactic heterogeneity of data and schema of the user profile. We present the architecture of Morpho and a case study to exemplify the approach followed in this current work. @en

In this paper we try to identify requirements, opportunities and problems in home media centers and we propose an approach to address them by describing an intelligent home media environment. The major issues investigated are coping with the information overflow in the current provision of TV programs and channels and the need for personalization to specific users by adapting to their age, interests, language abilities, and various context characteristics. The research presented in this paper follows from a collaboration between Eindhoven University of Technology, the Philips Applied Technologies group and Stoneroos Interactive Television. The work has been partially carried out within the ITEA-funded European project Passepartout, which also includes partners like Thomson, INRIA and ETRI. In the following chapter we describe the motivation and research problem in relation to related work, followed by an illustrative use case scenario. Afterwards, we explain our data model which starts with explaining the TV-Anytime structure and its enrichments with semantic knowledge from various ontologies and vocabularies. The data model description then serves as the background for understanding our proposed system architecture SenSee. Afterwards we go deeper into the user modeling part and explain how our personalization approach works. The latter elaborates on a design targeting interoperability and on semantic techniques for enabling intelligent context-aware personalization. In the implementation chapter we describe some practical issues as well as our main interface showcase, iFanzy. Future work and conclusions end this chapter.@en
