Abstract
A method and system for automatically generating regular expressions for relaxed matching of text patterns. A received input phrase expressed in a natural language is determined to be a plain text pattern. The plain text pattern is automatically tokenized, thereby generating a first token list. Rules loaded from a predefined rule set are automatically applied to the first token list to automatically generate a modified token list. The order of the rules being applied to the first token list is specified by the rule set. The modified token list is automatically converted into a regular expression that matches the plain text pattern and one or more variations of the plain text pattern. A utilization of the regular expression for an information extraction facilitates a recall and a precision of the information extraction.
