Thoth: improving experiences reuses in the scientific environment through workflow management system

The activities executed in the scientific environment are extremely dependent on knowledge from their performers. Thus, knowledge management initiatives are very important in this environment. One of the possibilities for improving the knowledge flow is to explore past experiences, resulting from the modeling and execution of previous scientific activities and handled by a workflow management system. This work presents Thoth, a system which aims at knowledge reuse in the scientific environment, during the planning, design and execution of scientific activities. This approach is integrated with a CBR approach, also described in this paper, with workflow systems and the use of ontologies.
