On the so-called Web 2.0, numerous Social Networking Sites (SNS) have known a tremendous success as they brought new ways to communicate, interact, learn about people, and share content with them. Besides improving informal social ties, transposing Awareness to the enterprise is very promising for promoting collaboration. However, it can easily lead to information overload, which means productivity loss. With our prototype, we propose a way to stimulate enterprise internal communication while improving the relevance of these interactions with the current working context of their users. This prototype is an efficient tool for cooperation and for discovering relevant people and knowledge.
