In this paper we introduce an experimental application to demonstrate the usage of context-based awareness cues in status updates, especially in SNS’s (Social Networking Services). The presented application allows users to add different descriptions of context information to their Twitter messages and Facebook status updates in a narrative format. We have also developed an adapted version of the system including conference-specific context-types such as the timetable of the presentations and indoor-location detection using Bluetooth beacons. One goal for the demonstrator is to explore the practical use of context abstractions in a conference setup and synthesize interesting insight based on the usage patterns during the event.

We propose a similar approach,messages and Facebook status updates in a narrative but give even more freedom for the user to select theformat. We have also developed an adapted version of the message to convey (including different abstractions), thussystem including conference-specific context-types such as giving the system possibility to gather more nuanced datathe timetable of the presentations and indoor-location from the activities and learn more abstract associations todetection using Bluetooth beacons.

Our Social Media hypothesis is that in many cases, rather than using exact terms for describing the situation, people would like to use ContextCapture Server more abstract notions. The purpose of the demonstrator is to explore the practical use of context abstractions in informal information sharing. In the conference setup, we would like Web to get people using the mobile application in their daily activities. The goal is to gather user experiences, analyze the actual usage patterns, and eventually synthesize interesting User WLAN insight from these patterns, such as context tags people have with Mobile connection used to refer to different talks and sessions during the Phone conference.
