Can GPT-4 Support Analysis of Textual Data in Tasks Requiring Highly Specialized Domain Expertise?

no code implementations24 Jun 2023 Jaromir Savelka, Kevin D. Ashley, Morgan A Gray, Hannes Westermann, Huihui Xu

We observed that, with a relatively minor decrease in performance, GPT-4 can perform batch predictions leading to significant cost reductions.

Explaining Legal Concepts with Augmented Large Language Models (GPT-4)

no code implementations15 Jun 2023 Jaromir Savelka, Kevin D. Ashley, Morgan A. Gray, Hannes Westermann, Huihui Xu

We compare the performance of a baseline setup, where GPT-4 is directly asked to explain a legal term, to an augmented approach, where a legal information retrieval module is used to provide relevant context to the model, in the form of sentences from case law.

Toward an Intelligent Tutoring System for Argument Mining in Legal Texts

no code implementations24 Oct 2022 Hannes Westermann, Jaromir Savelka, Vern R. Walker, Kevin D. Ashley, Karim Benyekhlef

We propose an adaptive environment (CABINET) to support caselaw analysis (identifying key argument elements) based on a novel cognitive computing framework that carefully matches various machine learning (ML) capabilities to the proficiency of a user.

Data-Centric Machine Learning in the Legal Domain

no code implementations17 Jan 2022 Hannes Westermann, Jaromir Savelka, Vern R. Walker, Kevin D. Ashley, Karim Benyekhlef

The results also indicate that enhancements to a data set could be considered, alongside the advancement of the ML models, as an additional path for increasing classification performance on various tasks in AI & Law.

Sentence Embeddings and High-speed Similarity Search for Fast Computer Assisted Annotation of Legal Documents

no code implementations21 Dec 2021 Hannes Westermann, Jaromir Savelka, Vern R. Walker, Kevin D. Ashley, Karim Benyekhlef

We use this observation in allowing annotators to quickly view and annotate sentences that are semantically similar to a given sentence, across an entire corpus of documents.

Lex Rosetta: Transfer of Predictive Models Across Languages, Jurisdictions, and Legal Domains

1 code implementation15 Dec 2021 Jaromir Savelka, Hannes Westermann, Karim Benyekhlef, Charlotte S. Alexander, Jayla C. Grant, David Restrepo Amariles, Rajaa El Hamdani, Sébastien Meeùs, Michał Araszkiewicz, Kevin D. Ashley, Alexandra Ashley, Karl Branting, Mattia Falduti, Matthias Grabmair, Jakub Harašta, Tereza Novotná, Elizabeth Tippett, Shiwanni Johnson

In this paper, we examine the use of multi-lingual sentence embeddings to transfer predictive models for functional segmentation of adjudicatory decisions across jurisdictions, legal systems (common and civil law), languages, and domains (i. e. contexts).
