Using context and preferences to implement self-adapting pervasive computing applications
Henricksen, Karen, Indulska, Jadwiga, & Rakotonirainy, Andry (2006) Using context and preferences to implement self-adapting pervasive computing applications. Software: Practice and Experience, 36(11-12), pp. 1307-1330.
Applications that use contextual information in order to adapt their behaviour to changing operating environments and user requirements are being explored as part of the vision of pervasive or ubiquitous computing. Despite recent advances in infrastructure to support these applications through the acquisition, interpretation and dissemination of context data from sensors, they remain prohibitively difficult to develop. The primary reason for this difficulty is a lack of appropriately high-level abstractions for describing, reasoning about and exploiting context information as a basis for adaptation. In this paper, we present our efforts to address this challenge, focusing on our novel approach involving the use of preference information as a basis for making flexible adaptation decisions. We also discuss our experiences in applying our conceptual and software frameworks for context and preference modelling to a case study involving the development of an adaptive communication application.
Citation countsare sourced monthly fromand citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
