CHR Dataset

The CHemical Reactions dataset (CHR) is a distantly supervised dataset dealing with binary interactions between chemicals.

Description

The dataset consists of 12,094 abstracts and their titles from PubMed. The annotation of chemicals was performed using the back-end of the semantic faceted search engine Thalia. Chemical compounds were selected from the annotated entities and aligned with the graph database Biochem4j, a freely available database that integrates several resources such as UniProt, KEGG and the NCBI Taxonomy. If two chemical entities were identified as related in Biochem4j, they were considered as positive instances in the dataset, otherwise as negative. In total, the corpus contains over 100,000 annotated chemicals and 30,000 reactions.
