Abstract:
1. A computer-implemented method of automatically generating regular expressions for relaxed matching of text patterns, comprising: a computing system receiving a first rule specifying a first operator that replaces a search phrase with a replacement regular expression; said computing system receiving one or more other rules; said computing system receiving an input phrase expressed in a natural language, the input phrase including the search phrase; said computing system determining that said received input phrase is a plain text pattern rather than a regular expression; prior to using an output regular expression to search documents for the search phrase and one or more variations of the search phrase, said computing system automatically generating the output regular expression by performing the steps of: subsequent to said converting the second list of tokens to the output regular expression and subsequent to said automatically generating the output regular expression, said computing system using the output regular expression to search the documents for the search phrase and the one or more variations of the search phrase.
