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
