Inference Engines

Inference Engines are a component of an artificial intelligence system that apply logical rules to a knowledge graph (or base) to surface new facts and relationships. Implementation of inference engines can proceed via induction or deduction. The process of inferring relationships between entities utilizing machine learning, machine vision, and natural language processing have exponentially increased the scale and value of knowledge graphs and relational databases in recent years. 
An example of deductive reasoning within an inference engine could be that San Francisco is in California. Therefore any entity located in San Francisco must also be located in California. An example of inductive reasoning within an inference engine could be that all tech companies with more than 100 employees tend to have CTO’s, and therefore any company meeting this criteria without a CTO must be missing a record.
