LexNLP by LexPredict

Information retrieval and extraction for real, unstructured legal text

LexNLP is a library for working with real, unstructured legal text, including contracts, plans, policies, procedures, and other material.

LexNLP provides functionality such as:

  • Segmentation and tokenization, such as
    • A sentence parser that is aware of common legal abbreviations like LLC. or F.3d.
    • Pre-trained segmentation models for legal concepts such as pages or sections.
  • Pre-trained word embedding and topic models, broadly and for specific practice areas
  • Pre-trained classifiers for document type and clause type
  • Broad range of fact extraction, such as:
    • Monetary amounts, non-monetary amounts, percentages, ratios
    • Conditional statements and constraints, like "less than" or "later than"
    • Dates, recurring dates, and durations
    • Courts, regulations, and citations
  • Tools for building new clustering and classification methods
  • Hundreds of unit tests from real legal documents
