+## Dataset Details
+This dataset contains **22,364** unique tokens (vocabulary size = 22,364), which is an extension from 93 tokens in the corresponding standard SMILES dataset. This expansion helps bridge the gap between SMILES and natural language, which has a large set of vocabulary to sufficiently express the nuances of language.
+
+For more details about the method of generating FG-enhanced SMILES, please refer to our paper, [FARM: Functional Group-Aware Representations for Small Molecules](https://arxiv.org/pdf/2410.02082), or visit our [GitHub repository](https://github.com/thaonguyen217/farm_molecular_representation) for implementation details.

+Below is a breakdown of the number of token types that represent different chemical elements:

+## Examples of FG-enhanced SMILES
+Below are some examples of FG-enhanced SMILES from the dataset. Each SMILES string is augmented with functional group annotations (e.g., `C_alkyl`, `O_ether`, `c_6`, `n_tertiary_amine`, etc.) to enhance the representation of molecular structures for machine learning models.
