Nuance Reasoning Framework: A Rule-Based System for Semantic Query Rewriting

We present the Nuance Reasoning Framework (NRF), a rule-based framework for semantic query rewriting and reasoning that is being utilized by Nuance Communications Inc. in speech-enabled conversational virtual assistant solutions for numerous automotive Original Equipment Manufacturer’s (OEM). We focus on the semantic rewriting task performed by NRF, which bridges the conceptual mismatch between the natural language front-end of automotive virtual assistants and their back end databases, and personalizes the results to the driver. We also describe many of its powerful features such as rewriter arbitration, query mediation and more.
