Presence based notification systems play a pivotal role in any collaborative working environment by providing near real time information about the status, locality and presence of the collaborators. Instant Messaging (IM) tools provide a simple low cost solution to support communication and collaboration in the working environment. With the wide adoption of smart phones, there is an increasing trend of using IM clients on mobile devices for exchanging and managing presence information. However, in modern organisations the use of collaborative tools is not limited only to IMs, but various other tools are also used, such as project management tools, meeting agenda, calendar and alike. In this paper we design, develop and implement an agile platform for ubiquitous presence management that relies on semantically interlinked vocabularies, existing information extraction tools for semantic enhancement of heterogeneous enterprise collaborative tools, continuous query processing for semantic integration and event detection in dynamic environment, and semantic transformation via query language for event-triggered notification actions based on the users context. We showcase our proposed solution by demonstrating a real world scenario for Cisco¿s Unified Presence System and we evaluate our solution in terms of requirements for Ubiquitous Presence Management System (UPMS) compared to related solutions, and overhead of each additional processing step, namely semantic transformation, continuous query processing and notification.
