This paper reviews different context classification systems that have been used to define types of context. Although existing classification systems cover various types of context, in the development of context aware applications only a few types of context have been used. This work aims to build a context classification model based on Activity Theory that brings together various research in co...

Multiple case studies in India, The Gambia, and Nigeria are the background for an empirically grounded framework of knowledge management (KM). Cultural diversity and gaps in the provision of infrastructure make managing knowledge challenging but necessary in developing countries. These environmental factors interact with organisational variables and technology to enable or constrain knowledge m...

Situated agents engaged in open systems continually face with external events requiring adequate services and behavioral responses. In these conditions agents should be able to improve their adaptivity over time, namely 1) to deal with and anticipate relevant changes and critical situations, 2) to temporally define relative priorities between goals varying their importance over time and 3) to u...

The educationally disadvantaged people in contextaware computing are those without any programming experience, and are unable to build context-aware applications with the current level of available prototyping support. iCAP is a system that assists this group of non-programmers in visually designing contextaware applications without writing any code. Individuals are then able to rapidly prototy...

Future computing environments will free the user from the constraints of the desk-top. Applications for a mobile environment should take advantage of contextual information, such as position, to ooer greater services to the user. In this paper, we present the Cyberguide project, in which we are building prototypes of a mobile context-aware tour guide. Knowledge of the user's current location, a...

Context-awareness in dynamic and unpredictable environments is a well-studied problem, and many approaches handle sensing, understanding, and acting upon context information. Entities in these environments are not in isolation, and oftentimes the manner in which entities coordinate depends on some (implicit) notion of their shared context. In this paper, we are motivated by the need to explicit...

Data mining, which aims at extracting interesting information from large collections of data, has been widely used as an effective decision making tool. Mining the datasets in the presence of context factors may improve performance and efficacy of data mining by identifying the unknown factors, which are not easily detectable in the process of generating an expected outcome. This paper proposes...
