Improving experiences reuse in environmental decision process

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