The KRAKEN toolset is a comprehensive interface for knowledge acquisition that operates in conjunction with the Cyc knowledge base. The KRAKEN system is de-signed to allow subject-matter experts to make mean-ingful additions to an existing knowledge base, without the benefit of training in the areas of artificial intelli-gence, ontology development, or logical representation. Users interact with KRAKEN via a natural-language in-terface, which translates back and forth between En-glish and the KB’s logical representation language. A variety of specialized tools are available to guide users through the process of creating new concepts, stating facts about those concepts, and querying the knowledge base. KRAKEN has undergone two independent perfor-mance evaluations. In this paper we describe the gen-eral structure and several of the features of KRAKEN, focussing on key aspects of its functionality in light of the specific knowledge-formation and acquisition chal-lenges they are intended to address.
