Legal NLP 1.6.0: Applicable Law, Dispute clauses, new embeddings and much more!

We are happy to announce the Legal NLP 1.6 is out.

Legal NLP is a John Snow Lab’s product, launched 2022 to provide state-of-the-art, autoscalable, domain-specific NLP on top of Spark.

With more than 600 models, featuring Deep Learning and Transformer-based architectures, NLP for legal includes:

  • Annotators to carry out Name Entity Recognition, Relation Extraction, Assertion Status / Understanding Entities in Context, Data Mapping to external sources, Deidentification, Question Answering, Table Question Answering, Sentiment Analysis, Summarization and much more, both training and inference!
  • Zero-shot Name Entity Recognition and Relation extraction;
  • 600+ pretrained Deep Learning / Transformer-based models;
  • Fully integration with Databricks, AWS or Azure;
  • 33+ notebooks and 25+ demos ready to showcase its features.
  • Full integration with NLP Lab (former Annotation Lab) for managing your annotation projects and train your legal NLP model in a zero-code fashion.
  • Compatiblity with Visual NLP, to combine OCR/Visual capabilities, as Signature Extraction, Form Recognition or Table detection, to Legal NLP.

Portuguese, Italian, French, English Legal Language Models

This is a list of new LM you can use to calculate the embeddings of your texts and train Legal nlp models on the top of them (including English, Portuguese, Italian and French):

Applicable Law NER and Classification

Classify paragraphs talking about Applicable Law and extract the laws from them using legclf_applicable_law_cuad_en and legner_applicable_law_clause.

APPLIC_LAW NER

APPLIC_LAW NER

Dispute Clauses Law NER and Classification

Classify paragraphs talking about Dispute Clauses using legclf_dispute_clauses_cuad and extract entities from them using legner_dispute_clauses.

COURT_NAME and RULES_NAME

COURT_NAME and RULES_NAME

11 New Clause Classifiers

Identify clauses in your legal agreements with this new clause binary classifiers. They can retrieve for you the following categories given an input paragraph:

– legclf_tax_matters_md: [tax_matter, other]
– legclf_choice_of_law_md:[choice_of_law, other]
– legclf_term_of_agreement_md:[term_of_agreement, other]
– legclf_attorney_fees_md:[attorney_fees, other]
– legclf_effect_of_termination_md:[effect_of_termination, other]
– legclf_affirmative_covenants_md:[affirmative_covenants, other]
– legclf_amendments_and_waivers_md:[amendments_and_waivers, other]
– legclf_miscellaneous_provisions_md: [miscellaneous_provisions, other]
– legclf_conditions_precedent_md: [conditions_precedent, other]
– legclf_fees_and_expenses_md:[fees_and_expenses, other]
– legclf_termination_for_cause_md:[termination_for_cause, other]

Contextual Parser (scalable rule-base NER)

Detect HEADERs and SUBHEADERs in legal agreements, for splitting purposes. Included in legpipe_header_subheader all along with other DL-based models for a hybrid extraction approach.

Split legal agreements into sections using pretrained pipelines

Combine NER, Contextual Parser and ChunkSplitting models to split legal agreements into different sections automatically, using legpipe_header_subheader

Headers detection

Augmented legner_contract_doc_parties

We have improved our Legal NER model to detect Document Types, Parties, Aliases, Former Names, Organizations and Effective Dates in legal agreements. The new model is lg(large) and can be found by the name of legner_contract_doc_parties_lg

New training notebooks and certification training

We have continued creating notebooks showcasing Legal NLP functionalities, with more than 33 notebooks available. Some of the new ones include:

  • Legal BertForTokenClassification training and inference, using any available Legal Bert model available in Hugging Face.
  • ContextualParser for carrying out rule-based NER at scale, both training and inference.
  • Binary, Multiclass and Multilabel classification of legal texts, training and inference.
  • RelationExtraction based on spanBert training.
  • EntityResolution (normalization) and Chunk Mapping (data augmentation training notebooks.
  • Using NER to split a text with ChunkSentenceSplitting.
  • Legal Use Case notebook: Creating graphs from Credit Agreements.

How to run

Legal NLP is very easy to run on both clusters and driver-only environments using johnsnowlabs library:

!pip install johnsnowlabs
nlp.install(force_browser=True)
nlp.start()

Fancy trying?

We’ve got 30-days free licenses for you with technical support from our legal team of technical and SME. Just go to https://www.johnsnowlabs.com/install/ and follow the instructions!
