A collaborative authoring tool for knowledge management

Stating that domain knowledge concepts are a mix of entity concepts and procedural concepts, we provide an overview of our software tool to exploit and interchange procedural knowledge represented as networks of semi-structured units. First, we introduce the notion of Procedural Knowledge Hierarchy; then we present the modeling of Procedural Knowledge by our software. We claim that the "bottom-up" approach that is being carried out with this tool is appropriate to gather new candidate terms for the construction of new domain ontology. We also detail the updating technique basing on the distributed tasks of a collaborative authoring project.
