LexPredict Legal Dictionaries



Many academic and commercial applications of natural language processing and machine learning to text can benefit from a controlled lexicon of expert-selected terms (i.e., a dictionary). This is especially true of highly technical language, such as legal text. However, no open source and freely-available dictionaries of this nature have been available.

Our goal is to change this fact. Our open-source document analytics platform, ContraxSuite, is just one of the projects that will benefit. We expect many other researchers and companies to both benefit and contribute.


The contents and organization of this legal dictionary repository will evolve as the community participates and our products evolve. However, our vision is to work towards multi-domain, multi-lingual, and cross-lingual resources for legal and regulatory text.
