Background Shotgun metagenomic sequencing is increasingly popular in taxonomic and resistome-profiling of polymicrobial samples due to its agnostic nature and data versatility. However, caveats include highcost, sequencing depth/sensitivity trade-offs, and challenging bioinformatic deconvolution. Targeted PCR-based pro...

We consider one of the cybernetic methods in biology related to the study of DNA chains. Namely, we are considering the problem of reconstructing the distance matrix for DNA chains. Such a matrix is formed on the basis of any of the possible algorithms for determining the distances between DNA chains. The objects of re...

Calculating solar-sensor zenith and azimuth angles for hyperspectral images collected by UAVs are important in terms of conducting bi-directional reflectance function (BRDF) correction or radiative transfer modeling-based applications in remote sensing. These applications are even more necessary to perform high-through...

HC4 (Healthcare Comprehensive Commons Corpus)

HC4 is a large-scale pretraining dataset containing over 65 billion tokens from diverse healthcare-related sources. The corpus was curated to enable systematic investigation of how data composition influences language model behavior, including potential demographic biases.

Dataset Overview

Dataset Name: HC4 (Healthcare Comprehensive Commons Corpus)

Size: 153GB (around 65 billion tokens)

Number of samples: 9.7+ million documents from diverse sources including peer-reviewed scientific literature collected from PubMed Central, Semantic Scholar, OpenAlex repositories

Repository: m42-health/HC4

Purpose: Pretraining large language models for healthcare applications

Format: .parquet files

License: Open licenses for each data sample permitting commercial use and redistribution

Organization: M42 (Abu Dhabi)

How to load the dataset

from datasets import load_dataset

dataset = load_dataset("m42-health/HC4")

Details

This dataset is accompanied by a peer-reviewed research paper accepted at EMNLP 2025 Conference, which presents comprehensive bias analysis methodology for clinical LLMs and provides transparency in dataset composition and curation.
