  The RareDis corpus contains more than 5,000 rare diseases and almost 6,000
clinical manifestations are annotated. Moreover, the Inter Annotator Agreement
evaluation shows a relatively high agreement (F1-measure equal to 83.5% under
exact match criteria for the entities and equal to 81.3% for the relations).
Based on these results, this corpus is of high quality, supposing a significant
step for the field since there is a scarcity of available corpus annotated with
rare diseases. This could open the door to further NLP applications, which
would facilitate the diagnosis and treatment of these rare diseases and,
therefore, would improve dramatically the quality of life of these patients.
