Legal Information Extraction Task

A Legal Information Extraction Task is a legal AI task that identifies and extracts structured legal information from unstructured legal documents through pattern recognition methods.

• AKA: Legal Data Extraction Task, Legal Entity Extraction Task, Legal Content Mining Task.
• Context:
  • It can typically extract Legal Named Entities with entity recognition models.
  • It can typically identify Legal Relationships through dependency parsing methods.
  • It can typically recognize Legal Concepts with domain-specific classifiers.
  • It can often extract Contract Clauses for clause analysis purposes.
  • It can often identify Legal Citations through reference extraction algorithms.
  • It can often recognize Legal Dates and Deadlines with temporal expression extraction.
  • It can often extract Legal Party Information for participant identification.
  • It can range from being a Rule-Based Legal Information Extraction Task to being a Learning-Based Legal Information Extraction Task, depending on its extraction methodology.
  • It can range from being a Entity-Level Legal Information Extraction Task to being a Document-Level Legal Information Extraction Task, depending on its extraction scope.
  • It can range from being a Single-Type Legal Information Extraction Task to being a Multi-Type Legal Information Extraction Task, depending on its information diversity.
  • It can range from being a Shallow Legal Information Extraction Task to being a Deep Legal Information Extraction Task, depending on its semantic depth.
