nlp4bia 2.1.2

Download NLP4BIA benchmarks and load datasets in their format

NLP4BIA Library

This repository provides a Python library for loading, processing, and utilizing biomedical datasets curated by the NLP4BIA research group at the Barcelona Supercomputing Center (BSC). The datasets are specifically designed for natural language processing (NLP) tasks in the biomedical domain.

Available Dataset Loaders

The library currently supports the following dataset loaders, which are part of public benchmarks:

1. Distemist

• Description: A dataset for disease mentions recognition and normalization in Spanish medical texts.
• Zenodo Repository: Distemist Zenodo

2. Meddoplace

• Description: A dataset for place name recognition in Spanish medical texts.
• Zenodo Repository: Meddoplace Zenodo

3. Medprocner

• Description: A dataset for procedure name recognition in Spanish medical texts.
• Zenodo Repository: Medprocner Zenodo

4. Symptemist

• Description: A dataset for symptom mentions recognition in Spanish medical texts.
• Zenodo Repository: Symptemist Zenodo

Installation

pip install nlp4bia

Quick Start Guide

Example Usage

Here's how to use one of the dataset loaders, such as DistemistLoader:

from nlp4bia.datasets.benchmark.distemist import DistemistLoader

# Initialize loader
distemist_loader = DistemistLoader(lang="es", download_if_missing=True)

# Load and preprocess data
dis_df = distemist_loader.df
print(dis_df.head())

Dataset folders are automatically downloaded and extracted to the ~/.nlp4bia directory.
