Revisiting Relation Extraction in the era of Large Language Models [PDF]

open access: yesAnnual Meeting of the Association for Computational Linguistics, 2023
Relation extraction (RE) is the core NLP task of inferring semantic relationships between entities from text. Standard supervised RE techniques entail training modules to tag tokens comprising entity spans and then predict the relationship between them ...

GPT-RE: In-context Learning for Relation Extraction using Large Language Models [PDF]

open access: yesConference on Empirical Methods in Natural Language Processing, 2023
In spite of the potential for ground-breaking achievements offered by large language models (LLMs) (e.g., GPT-3), they still lag significantly behind fully-supervised baselines (e.g., fine-tuned BERT) in relation extraction (RE).

Zero-shot Temporal Relation Extraction with ChatGPT [PDF]

open access: yesWorkshop on Biomedical Natural Language Processing, 2023
The goal of temporal relation extraction is to infer the temporal relation between two events in the document. Supervised models are dominant in this task. In this work, we investigate ChatGPT’s ability on zero-shot temporal relation extraction.

DREEAM: Guiding Attention with Evidence for Improving Document-Level Relation Extraction [PDF]

open access: yesConference of the European Chapter of the Association for Computational Linguistics, 2023
Document-level relation extraction (DocRE) is the task of identifying all relations between each entity pair in a document. Evidence, defined as sentences containing clues for the relationship between an entity pair, has been shown to help DocRE systems ...

Joint extraction of entities and relations by entity role recognition

open access: yesCognitive Robotics, 2022
Joint extracting entities and relations from unstructured text is a fundamental task in information extraction and a key step in constructing large knowledge graphs, entities and relations are constructed as relational triples of the form (subject ...

Document-level Relation Extraction as Semantic Segmentation [PDF]

open access: yesInternational Joint Conference on Artificial Intelligence, 2021
Document-level relation extraction aims to extract relations among multiple entity pairs from a document. Previously proposed graph-based or transformer-based models utilize the entities independently, regardless of global information among relational ...

Entity Structure Within and Throughout: Modeling Mention Dependencies for Document-Level Relation Extraction [PDF]

open access: yesAAAI Conference on Artificial Intelligence, 2021
Entities, as the essential elements in relation extraction tasks, exhibit certain structure. In this work, we formulate such entity structure as distinctive dependencies between mention pairs.
