Corpus of Online Medical EnTities: the cometA corpus

COMETA: the corpus of online medical entities

This repo holds code for running baseline models presented in our paper: COMETA: A Corpus for Medical Entity Linking in the Social Media at EMNLP 2020.

COMETA is an entity linking dataset of layman medical terminology. It has been collected by analysing four years of content in 68 health-themed subreddits and annotating the most frequent with their corresponding SNOMED-CT entities. Each term is assigned two annotations: a General SNOMED-CT identifier and a Specific one, denoting respectively the literal and contextual meaning of the term.
