Abstract
A concept synonym matching engine identifies and extracts specific information referenced in a selection of text and matches the information to a set of defined concepts. The engine is able to perform this identification and matching in the presence of errors (e.g., misspellings, etc.) or variations in the description of those concepts (e.g., use of different terms to define the same idea). The engine performs these functions by tokenizing an input string of text and matching these tokens to tokens of a pattern that represents a concept to be matched. The engine matches the pattern to a sub-string of text, scores the match, and uses the score to determine whether the concept is present in the input string or to select the optimal match.
