lexnlp.extract.en.definitions: Extracting definition statements

The lexnlp.extract.en.definitions module contains methods that allow for the extraction of definitional statements from text. Example statements that are covered by default in this module are:

• X shall [not] include …
• X shall have the meaning …
• X is hereby changed to …
• X shall be interpreted …
• X shall for purposes …

• The word “X” includes every description of …
• The term “X” means …
• Description of term (the “x”)

Extracting constraints

lexnlp.extract.en.definitions.get_definitions(text, return_sources=False, decode_unicode=True) → typing.Generator

Find possible definitions in natural language. :param decode_unicode: :param return_sources: :param text: :return:

Example

>>> import lexnlp.extract.en.definitions
>>> text = 'and Acme, LLC ("Client")'
>>> print(list(lexnlp.extract.en.definitions.get_definitions(text)))
['Client']
>>> text = "“Advance” means a Revolving Credit Advance"
>>> print(list(lexnlp.extract.en.definitions.get_definitions(text)))
['Advance']
