Information management from social and documentary sources in organizations

•We have designed an ontology describing a knowledge ecosystem.•Our ontology permits to index both documentary and social media resources.•Our ontology allows users of the ecosystem to organize themselves into free groups.•We build a prototype, which implements our ontology.•We test the prototype with students of an university course.

The wide adoption of social and connected tools in organizations leads them to think again about their behavior regarding how they manage their resources. They now consider the resources users can produce on various social media and how correctly index them in the organization knowledge base. We present in this paper the model of a digital ecosystem, which permits the indexing of either documentary resources or those produced on a social platform with the help of an ontology.
