Description

Written for a seminar at Universiteit Twente (Netherlands) in March 2009, this presentation by Adrien Joly (Alcatel-Lucent Bell Labs France) introduces approaches for improved enterprise communication and collaboration, which motivates a convergent framework of real-time contextual notifications based on employees' work context. The framework is presented and current research issues (work in progress) are introduced.

Background on CSCE Previo us wor Computer-Supported Collaborative Environments ks  [Dourish'92]: “Shared Feedback”:  Human annotation of tracked actions on documents  Add useful context information, and avoid duplication  [Amelung'05]: Context-Aware Activity Notification System (CANS):  Based on Sakai Collaboration & Learning Environment (web platform)  Social context only: “current membership, the collective goals of individuals” – Context = project / community of practice !  Basically, an adaptive publication/subscription system for web-based communities  Applied workspace awareness systems:  Collaborative bug tracking [Ellis'07]  Configuration management [Sarma'08]  Collaborative software development [Biehl'07] Copyright © 2009 Alcatel-Lucent, d.r. 14 | Awareness without Overload | March 2009

Discussion

Discussion Contextual Notification Framework to enable Ambient Awareness:  Logging user actions on his workstation  Event propagation with contextual synthesis  Context similarity evaluation for filtering relevant notifications  Designed for minimal user interaction and system transparency (privacy & trust) Next steps:  Iterative improvement of software  In-lab experiment to evaluate user acceptance and quality of logic  Generalization of the framework (outside the enterprise) Copyright © 2009 Alcatel-Lucent, d.r. 33 | Awareness without Overload | March 2009
