• Title: The Fellowship of the Authors: Disambiguating Names from Social Network Context
• Authors: Ryan Muther, David Smith
• Abstract summary: Authority lists with extensive textual descriptions for each entity are lacking and ambiguous named entities. We combine BERT-based mention representations with a variety of graph induction strategies and experiment with supervised and unsupervised cluster inference methods. We find that in-domain language model pretraining can significantly improve mention representations, especially for larger corpora.

• Abstract: Most NLP approaches to entity linking and coreference resolution focus on retrieving similar mentions using sparse or dense text representations. The common "Wikification" task, for instance, retrieves candidate Wikipedia articles for each entity mention. For many domains, such as bibliographic citations, authority lists with extensive textual descriptions for each entity are lacking and ambiguous named entities mostly occur in the context of other named entities. Unlike prior work, therefore, we seek to leverage the information that can be gained from looking at association networks of individuals derived from textual evidence in order to disambiguate names. We combine BERT-based mention representations with a variety of graph induction strategies and experiment with supervised and unsupervised cluster inference methods. We experiment with data consisting of lists of names from two domains: bibliographic citations from CrossRef and chains of transmission (isnads) from classical Arabic histories. We find that in-domain language model pretraining can significantly improve mention representations, especially for larger corpora, and that the availability of bibliographic information, such as publication venue or title, can also increase performance on this task. We also present a novel supervised cluster inference model which gives competitive performance for little computational effort, making it ideal for situations where individuals must be identified without relying on an exhaustive authority list.

• Large-Scale Label Interpretation Learning for Few-Shot Named Entity Recognition [5.262708162539423]
  Few-shot named entity recognition (NER) detects named entities within text using only a few examples. One promising line of research is to leverage natural language descriptions of each entity type. In this paper, we explore the impact of a strong semantic prior to interpret verbalizations of new entity types.

  We study the task of seed-guided fine-grained entity typing in science and engineering domains. We propose SEType which first enriches the weak supervision by finding more entities for each seen type from an unlabeled corpus. It then matches the enriched entities to unlabeled text to get pseudo-labeled samples and trains a textual entailment model that can make inferences for both seen and unseen types.

Our experiments show that given only three seed documents per category, our framework can achieve an accuracy of about 92%.

  Entities are at the center of how we represent and aggregate knowledge.

We propose GENRE, the first system that retrieves entities by generating their unique names, left to right, token-by-token in an autoregressive fashion.
