Neuro-Symbolic Natural Language Processing

Abstract
Despite the performance leaps delivered by Large Language Models (LLMs), NLP systems based only on deep learning architectures still have limiting capabilities in terms of delivering safe and controlled reasoning, interpretability, and adaptability within complex and specialised domains, restricting their use in areas where reliability and trustworthiness are crucial. Neur-symbolic NLP methods seek to overcome these limitations by integrating the flexibility of contemporary language models with the control/interpretability of symbolic methods. This hybrid approach brings the promise to both enhance inference capabilities and to deepen the theoretical understanding of LLMs. This tutorial aims to bridge the gap between the practical performance of LLMs and the principled modelling of language and inference of formal methods. We provide an overview of formal foundations in linguistics and reasoning, followed by contemporary architectural mechanisms to interpret, control, and extend NLP models. Balancing theoretical and practical activities, the tutorial is suitable for PhD students, experienced researchers, and industry practitioners.
