Mind Your Neighbours: Leveraging Analogous Instances for Rhetorical Role Labeling for Legal Documents

no code implementations31 Mar 2024 T. Y. S. S Santosh, Hassan Sarwat, Ahmed Abdou, Matthias Grabmair

Rhetorical Role Labeling (RRL) of legal judgments is essential for various tasks, such as case summarization, semantic search and argument mining.

ECtHR-PCR: A Dataset for Precedent Understanding and Prior Case Retrieval in the European Court of Human Rights

1 code implementation31 Mar 2024 T. Y. S. S Santosh, Rashid Gustav Haddad, Matthias Grabmair

In common law jurisdictions, legal practitioners rely on precedents to construct arguments, in line with the doctrine of \emph{stare decisis}.

Query-driven Relevant Paragraph Extraction from Legal Judgments

no code implementations31 Mar 2024 T. Y. S. S Santosh, Elvin Quero Hernandez, Matthias Grabmair

We notice that the legal pre-training handles distribution shift on the corpus side but still struggles on query side distribution shift, with unseen legal queries.

Beyond Borders: Investigating Cross-Jurisdiction Transfer in Legal Case Summarization

no code implementations28 Mar 2024 T. Y. S. S Santosh, Vatsal Venkatkrishna, Saptarshi Ghosh, Matthias Grabmair

In particular, we investigate whether supplementing models with unlabeled target jurisdiction corpus and extractive silver summaries obtained from unsupervised algorithms on target data enhances transfer performance.

From Dissonance to Insights: Dissecting Disagreements in Rationale Construction for Case Outcome Classification

no code implementations18 Oct 2023 Shanshan Xu, T. Y. S. S Santosh, Oana Ichim, Isabella Risini, Barbara Plank, Matthias Grabmair

Overall, our case study reveals hitherto underappreciated complexities in creating benchmark datasets in legal NLP that revolve around identifying aspects of a case's facts supposedly relevant to its outcome.

VECHR: A Dataset for Explainable and Robust Classification of Vulnerability Type in the European Court of Human Rights

1 code implementation17 Oct 2023 Shanshan Xu, Leon Staufer, T. Y. S. S Santosh, Oana Ichim, Corina Heri, Matthias Grabmair

Our results demonstrate the challenging nature of the task with lower prediction performance and limited agreement between models and experts.

Leveraging Task Dependency and Contrastive Learning for Case Outcome Classification on European Court of Human Rights Cases

no code implementations1 Feb 2023 T. Y. S. S Santosh, Marcel Perez San Blas, Phillip Kemper, Matthias Grabmair

We report on an experiment in case outcome classification on European Court of Human Rights cases where our model first learns to identify the convention articles allegedly violated by the state from case facts descriptions, and subsequently uses that information to classify whether the court finds a violation of those articles.

Contrastive Learning

Zero-shot Transfer of Article-aware Legal Outcome Classification for European Court of Human Rights Cases

no code implementations1 Feb 2023 T. Y. S. S Santosh, Oana Ichim, Matthias Grabmair

In this paper, we cast Legal Judgment Prediction on European Court of Human Rights cases into an article-aware classification task, where the case outcome is classified from a combined input of case facts and convention articles.

Deconfounding Legal Judgment Prediction for European Court of Human Rights Cases Towards Better Alignment with Experts

1 code implementation25 Oct 2022 T. Y. S. S Santosh, Shanshan Xu, Oana Ichim, Matthias Grabmair

This work demonstrates that Legal Judgement Prediction systems without expert-informed adjustments can be vulnerable to shallow, distracting surface signals that arise from corpus construction, case distribution, and confounding factors.
