LEGAL-BERT: The muppets straight out of law school

I Chalkidis, M Fergadiotis, P Malakasiotis… - arXiv preprint arXiv …, 2020 - arxiv.org
BERT has achieved impressive performance in several NLP tasks. However, there has been
limited investigation on its adaptation guidelines in specialised domains. Here we focus on …

LexGLUE: A benchmark dataset for legal language understanding in English

I Chalkidis, A Jana, D Hartung, M Bommarito… - arXiv preprint arXiv …, 2021 - arxiv.org
Laws and their interpretations, legal arguments and agreements\ are typically expressed in
writing, leading to the production of vast corpora of legal text. Their analysis, which is at the …

A Deep Learning Approach to Contract Element Extraction.

I Chalkidis, I Androutsopoulos - JURIX, 2017 - books.google.com
We explore how deep learning methods can be used for contract element extraction. We show
that a BILSTM operating on word, POS tag, and tokenshape embeddings outperforms the …

Neural legal judgment prediction in English

I Chalkidis, I Androutsopoulos, N Aletras - arXiv preprint arXiv:1906.02059, 2019 - arxiv.org
Legal judgment prediction is the task of automatically predicting the outcome of a court case,
given a text describing the case's facts. Previous work on using neural models for this task …

An empirical study on large-scale multi-label text classification including few and zero-shot labels

I Chalkidis, M Fergadiotis, S Kotitsas… - arXiv preprint arXiv …, 2020 - arxiv.org
Large-scale Multi-label Text Classification (LMTC) has a wide range of Natural Language
Processing (NLP) applications and presents interesting challenges. First, not all labels are …

Large-scale multi-label text classification on EU legislation

I Chalkidis, M Fergadiotis, P Malakasiotis… - arXiv preprint arXiv …, 2019 - arxiv.org
We consider Large-Scale Multi-Label Text Classification (LMTC) in the legal domain. We
release a new dataset of 57k legislative documents from EURLEX, annotated with ~4.3k …

Extracting contract elements

I Chalkidis, I Androutsopoulos, A Michos - … of the 16th edition of the …, 2017 - dl.acm.org
We study how contract element extraction can be automated. We provide a labeled dataset
with gold contract element annotations, along with an unlabeled dataset of contracts that can …

Obligation and prohibition extraction using hierarchical RNNs

I Chalkidis, I Androutsopoulos, A Michos - arXiv preprint arXiv:1805.03871, 2018 - arxiv.org
We consider the task of detecting contractual obligations and prohibitions. We show that a
self-attention mechanism improves the performance of a BILSTM classifier, the previous state …

Deep learning in law: early adaptation and legal word embeddings trained on large corpora

I Chalkidis, D Kampas - Artificial Intelligence and Law, 2019 - Springer
Deep Learning has been widely used for tackling challenging natural language processing
tasks over the recent years. Similarly, the application of Deep Neural Networks in legal …

Greek-bert: The greeks visiting sesame street

J Koutsikakis, I Chalkidis, P Malakasiotis… - … Hellenic conference on …, 2020 - dl.acm.org
Transformer-based language models, such as BERT and its variants, have achieved state-of-the-art
performance in several downstream natural language processing (NLP) tasks on …
