RegexGenerator

This project contains the source code of a tool for generating regular expressions for text extraction and classification (flagging):

automatically,
based only on examples of the desired behavior,
without any external hint about how the target regex should look like.

An online, interactive version of this engine is accessible at: http://regex.inginf.units.it/

RegexGenerator was developed at the [Machine Learning Lab, University of Trieste, Italy] (http://machinelearning.inginf.units.it).

The provided engine is a developement release (1) that implements the algorithms published in our articles (2):

Bartoli, De Lorenzo, Medvet, Tarlao, Inference of Regular Expressions for Text Extraction from Examples, IEEE Transactions on Knowledge and Data Engineering, 2016
Bartoli, De Lorenzo, Medvet, Tarlao, Can a machine replace humans in building regular expressions? A case study, IEEE Intelligent Systems, 2016
Bartoli, De Lorenzo, Medvet, Tarlao, Virgolin, Evolutionary Learning of Syntax Patterns for Genic Interaction Extraction, ACM Genetic and Evolutionary Computation Conference (GECCO), 2015, Madrid (Spain)

More details about the project can be found on Machine Learning Lab news pages.

We hope that you find this code instructive and useful for your research or study activity.

If you use our code in your reasearch please cite our work and please share back your enhancements, fixes and modifications.

Project Structure

The RegexGenerator project is organized in three NetBeans Java subprojects:

ConsoleRegexTurtle: cli frontend for the GP engine
MaleRegexTurtle: provides the regular expression tree representation
Random Regex Turtle: GP search engine
