The ability to create and interact with large-scale domainspecific knowledge bases from unstructured/semi-structured data is the foundation for many industry-focused cognitive systems. We will demonstrate the Content Services system that provides cloud services for creating and querying highquality domain-specific knowledge bases by analyzing and integrating multiple (un/semi)structured content sources. We will showcase an instantiation of the system for a financial domain. We will also demonstrate both cross-lingual natural language queries and programmatic API calls for interacting with this knowledge base.

A framework for diagnosing and characterizing the failure propagation of various components in a CNC machine tool using real time knowledge-based simulation is discussed. The input data necessary for conducting simulation is obtained fTom a knowledge base structured using frames. Preventive maintenance and sudden failures are modeled. The implemented system provides an integrated environment for the maintenance supervisors to obtain early warnings about the expected failure times of different components and the stoppage time of the machine tool.
