We present AKIRA, an agent-based hybrid architecture designed for cognitive modeling. We describe some of the underlying ideas motivating its development, such as the possibility of exploiting distributed representations and performing parallel, dynamic and context aware computation. We illustrate its main components and capabilities and compare it with some related cognitive architectures, such as DUAL and Copycat. We present also a sample simulation in the visual search domain, exploiting AKIRA's peculiarities for cognitive modeling.

In light of recent attempts to design context-aware mobile phones, this paper contributes by providing findings from a study of mobile phone talk in context. We argue the benefits of investigating empirically the ways in which a place is interactionally constituted as appropriate, or not, for a mobile phone conversation. Based on a study of naturally occurring mobile phone talk, we show how people handle calls in potentially difficult situations. Availability is negotiated, and it is not always agreed on whether a situation is appropriate. these findings pose challenges to the design of context-aware telephony.

Enterprises develop procedures to address focuses in any case. However, procedures result often in sub-optimal solutions for any specific focus. As a consequence, each actor develops his own practice to address a focus in a given context, focus and its context being particular and specific. the modeling of practices is not an easy task because there are as many practices as contexts of occurrence. this paper proposes a way to deal practically with practices. Based on our definition of context, we present a context-based representation formalism for modeling task accomplishment by users called contextual graphs and its interest for the tasks of incremental acquisition, learning and explanation. contextual graphs are discussed on a modeling in information retrieval.

We investigate contextual categorizations, i.e., categorizations holding only with respect to a specific context, from a formal semantics perspective. contexts are modeled as sets of description logic models for different languages, and operations on contexts are defined which provide a new formal characterization of context interplay and especially of a form of context abstraction which we call focus. the framework is compared with relevant related work and discussed from the viewpoint of contexttheory issues. Finally, a simple scenario is formalized.

In ubiquitous computing, the user will be interrupted in performing a task only if the information is relevant to the task or highly important in the situation to justify the interrupt. the information selection and presentation therefore should be adapted to the user and his current context of use. Nowadays, uncounted Content-Management Systems provide access to a large amount of information, but without context, information is just data. this paper introduces context-Management as a new approach for the design of contextaware systems in ubiquitous computing. As a proof of concept we illustrate three prototypical implementations of contextualized information systems in different applications domains and decompose the underlying framework into its foundational components.

In this paper, we give an overview of our current work on introducing context as first-class objects in Lucid. It allows us to write programs in Lucx (Lucid enriched withcontext) in a high level of abstraction which is closer to the problem domain. We include a discussion on contexttheory, representation of context aggregations, and the syntax and semantic rules of Lucx. the implementation of Lucx in GIPSY, a platform under development for compiling Lucid family of languages, is also discussed.
