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
