Presence or Absence: Are Unknown Word Usages in Dictionaries?

1 code implementation • 2 Jun 2024 • Xianghe Ma, Dominik Schlechtweg, Wei Zhao

It leverages a graph-based clustering approach to predict mappings between unknown word usages and dictionary entries for Subtask 1, and generates dictionary-like definitions for those novel word usages through the state-of-the-art Large Language Models such as GPT-4 and LLaMA-3 for Subtask 2.

Graph-based Clustering for Detecting Semantic Change Across Time and Languages

To address this issue, we propose a graph-based clustering approach to capture nuanced changes in both high- and low-frequency word senses across time and languages, including the acquisition and loss of these senses over time.
