Context-awareness is increasing of importance in achieving an effective communication of information and provision of services. Then, besides taking into account “classical” user-related features, other contextdependent factors (i.e. users’ location, activity, emotional state and technical characteristics of the used device) have to be considered. In this paper, we present the Personalization c...

In this paper we focus on formal concepts for an integrated modeling of complex systems. We take our examples from the field of sociotechnical systems where we state a great need for model-based reasoning regarding questions of system safety and the definition of long-term management policies. We lay our special focus on systemic capabilities related to context adaptive behavior with special co...

We aim to provide an advanced context-aware service based on various sensors and home appliances. We propose a concept of an agent-based cooperative framework for heterogeneous sensors. Our framework can adjust detection, addition, and removal of sensors to provide context-aware services. We implemented a prototype system and performed experiments to confirm the effectiveness of our framework.

We generalize the classic Allingham and Sandmo’s model of tax evasion considering heterogeneous agents with different degrees of tax morale and matchable, as opposed to non-matchable, income. The Tax Agency evolves its control scheme, maximizing the revenues from fines, and takes into account some minimal information on the taxpayers. We compare different audit policies and find that the most e...

The research presented in this paper is part of a 5-year renewable national research program in Canada, namely the NSERC/iCORE/Xerox/Markin research chair program that aims to explore possibilities of adaptive mobile learning and to provide learners with a learning environment which facilitates personalized learning at any time and any place. One of the sub-projects of this 5-year national rese...

In content based image retrieval, systems allow users to ask for objects similar in shape to a query object. However, there is no clear understanding of how computational shape similarity corresponds to human shape similarity. In this paper several shape similarity measures were evaluated on planar, connected, non-occluded binary shapes. Shape similarity using algebraic moments, spline curve di...

Mobile services and applications are used in changing contexts and surroundings. These services are made up of context-aware and offer contextually relevant information to the user. These facilities help to find the data and its use. Keywordscontext-aware, location-aware, mobile computing, middle ware.

The structure of social relations is fundamental for the construction of plausible simulation scenarios. It shapes the way actors interact and create their identity within overlapping social contexts. Each actor interacts in multiple contexts within different types of social relations that constitute their social space. In this article, we present an approach to model structured agent societies...

off the physical visualization. This could be offered in varying degrees of depth such as contextual help is generally offered. In conclusion, it is essential that diagnostic systems make better use of existing visual aids such as multi-dimensional models and diagnostic network browsers to better serve users. The integration of such tools requires that the physical and abstract representations ...

Intelligent agents have to be able to merge (possibly conflicting) pieces of information obtained from different sources to produce a coherent picture of the world. In this paper we propose a multi-agent model of context-sensitive merging. We show that the success of the model depends, to a large extent, on the availability of suitable merging operations on epistemic states. As a result, we inv...
