# PubChem Canonical SMILES and Descriptions Pair Classification

This dataset contains pairs of canonical SMILES strings and their corresponding descriptions, with labels indicating whether they refer to the same chemical entity. A label of 1 means the SMILES string and the description correspond to the same entity, while a label of 0 indicates they do not. The dataset is sourced from PubChem ([ChEBI](https://www.ebi.ac.uk/chebi/) source), and it provides valuable information for tasks involving chemical entity matching and description analysis.
