The important role given to domain ontologies for knowledge representation implies increasing need for development and maintenance of them. However, we have a scarcity of tools supporting the life cycle from creation to management and adaptation. Our research group focuses on developing an autonomic process for knowledge representation through a systematic evaluation and redesign of ontologies. This autonomic behavior intends to specify a self-management repository for domain ontologies with an evolution strategy to make adjustments to optimize and protect against undesirable scenarios. In this article, we present the repository with embedded c features to perform the abstraction action of knowledge upon documents collection, using the background knowledge already specified in the domain ontologies.
