Decoding Alignment: A Critical Survey of LLM Development Initiatives through Value-setting and Data-centric Lens

Ilias Chalkidis

AI Alignment, primarily in the form of Reinforcement Learning from Human Feedback (RLHF), has been a cornerstone of the post-training phase in developing Large Language Models (LLM…

Processing Long Legal Documents with Pre-trained Transformers: Modding LegalBERT and Longformer

Dimitris Mamakas, Petros Tsotsi, Ion Androutsopoulos +1

Pre-trained Transformers currently dominate most NLP tasks. They impose, however, limits on the maximum input length (512 sub-words in BERT), which are too restrictive in the legal…

An Exploration of Hierarchical Attention Transformers for Efficient Long Document Classification

Ilias Chalkidis, Xiang Dai, Manos Fergadiotis +2

Non-hierarchical sparse attention Transformer-based models, such as Longformer and Big Bird, are popular approaches to working with long documents. There are clear benefits to thes…

Realistic Zero-Shot Cross-Lingual Transfer in Legal Topic Classification

Stratos Xenouleas, Alexia Tsoukara, Giannis Panagiotakis +2

We consider zero-shot cross-lingual transfer in legal topic classification using the recent MultiEURLEX dataset. Since the original dataset contains parallel documents, which is un…

Revisiting Transformer-based Models for Long Document Classification

Xiang Dai, Ilias Chalkidis, Sune Darkner +1

The recent literature in text classification is biased towards short text sequences (e.g., sentences or paragraphs). In real-world applications, multi-page multi-paragraph document…

MultiEURLEX -- A multi-lingual and multi-label legal document classification dataset for zero-shot cross-lingual transfer

Ilias Chalkidis, Manos Fergadiotis, Ion Androutsopoulos

We introduce MULTI-EURLEX, a new multilingual dataset for topic classification of legal documents. The dataset comprises 65k European Union (EU) laws, officially translated in 23 l…
