 # Dataset description
-This dataset collection contains ~70K curated active compound lists from 73 [PubChem](https://pubchem.ncbi.nlm.nih.gov) BioAssay (AID) datasets, focusing on known assay interference artifacts. We downloaded raw assay results from PubChem using their AID identifiers and extracted only the compounds labeled as "Active."
+This dataset collection contains ~70K curated active compound lists from 73 different [PubChem](https://pubchem.ncbi.nlm.nih.gov) BioAssay (AID) datasets, focusing on known assay interference artifacts. We downloaded raw assay results from PubChem using their AID identifiers and extracted only the compounds labeled as "Active."
 
 Then We applied SMILES standardization using RDKit and MolVS, including molecule sanitization and fragment removal.
