A knowledge and reasoning toolkit for cognitive applications

This paper presents a knowledge and reasoning toolkit for developing cognitive applications which have significant requirements for managing structured and semi-structured data. Our system provides enhanced querying and reasoning capabilities along with natural language processing support and the ability to automatically extract data from PDF documents.We also have the capability to manage ontologies in a user-friendly way. Our system is implemented as a set of Web services, and we provide enhanced clients to allow applications to easily access our knowledge and reasoning toolkit.
