[edit] About the project

This NSF-supported project aims to explore personalization and social networking for short-term communities. Using academic research conferences as a test bed, the project explored new methods to leverage information about user interests (available from multiple external resources) and develop techniques to facilitate use of existing social technologies. In the course of the project we implemented and explored Conference Navigator 3 along with a number of recommendation and visualization approaches for it.

[edit] Systems

Conference Navigator 3 is a social conference support system. It offers an enhanced version of traditional tools: conference schedule and attendee list. It combines social tagging and social navigation features, but also use accumulated data from existing long-term communities (e.g. Facebook, CiteULike, Mendeley) to help users to find the relevant sessions to attend and to determine the appropriate people to make contact with during the conference. more
