RL3 Pattern

An RL3 Pattern is a special kind of a search pattern that an RL3 Engine attempts to match on the given input (e.g. text) to extract meaningful output (e.g. data facts annotated from the input text).

A standard RL3 Pattern is based on:

• regular expressions;
• various built-in and user-defined extensions to optimize search.
