ToxHabits-NER stands for Toxic Habits Named Entity Recognition. It is a gold-standard annotated dataset focused on the detection and classification of toxic habit mentions — such as tobacco use, alcohol consumption, and illicit drug use — within clinical texts written in Spanish. This repository includes the corpus' train and test sets in multiple formats. The annotations cover mentions of toxic habits, associated behaviors, and contextual cues relevant for clinical and epidemiological studies. For more information, please check the attached README file. ToxHabits-NER was developed by the Barcelona Supercomputing Center's NLP for Biomedical Information Analysis team. It is intended as a resource to advance research on toxic habit extraction and normalization tasks from medical documents. This dataset is part of the ToxHabits Shared Task of BioCreative IX.
