Management of Twitter Resources in a Semantic Organizational Memory

The Social Web supports the sharing of resources and the communication between members of communities. These have various cultural goals in specific domains and focus on the exchange of significant resources. Informal communication, but nevertheless considered useful, takes more and more importance due to the individual needs for sharing information. The easy access to social media services encourages people to produce such informal communication. In this paper we propose a way to manage in organizational memories, information produced on Twitter, mainly into tweets. The first part is the description of a system (an Organizational Memory) able to index tweets and related resources semantically. The second part is a scenario that shows the circulation of information between Twitter and such a system. The third part presents the definition of a semantic extension of tweet hash tags and a way to generate it.
