# The PubMed Corpus in MedRAG
This HF dataset contains the snippets from the PubMed corpus used in [MedRAG](https://arxiv.org/abs/2402.13178). It can be used for medical Retrieval-Augmented Generation (RAG).
## News
- (02/26/2024) The "id" column bas been reformatted. A new "PMID" column is added.
## Dataset Details
### Dataset Descriptions
[PubMed](https://pubmed.ncbi.nlm.nih.gov/) is the most widely used literature resource, containing over 36 million biomedical articles.
For MedRAG, we use a PubMed subset of 23.9 million articles with valid titles and abstracts.
This HF dataset contains our ready-to-use snippets for the PubMed corpus, including 23,898,701 snippets with an average of 296 tokens.
### Dataset Structure
Each row is a snippet of PubMed, which includes the following features:
- id: a unique identifier of the snippet
- title: the title of the PubMed article from which the snippet is collected
- content: the abstract of the PubMed article from which the snippet is collected
- contents: a concatenation of 'title' and 'content', which will be used by the [BM25](https://github.com/castorini/pyserini) retriever
## Uses
<!-- Address questions around how the dataset is intended to be used. -->
### Direct Use
<!-- This section describes suitable use cases for the dataset. -->
```shell
git clone https://huggingface.co/datasets/MedRAG/pubmed
```
### Use in MedRAG
```python
>> from src.medrag import MedRAG
>> question = "A lesion causing compression of the facial nerve at the stylomastoid foramen will cause ipsilateral"
>> options = {
"A": "paralysis of the facial muscles.",
"B": "paralysis of the facial muscles and loss of taste.",
"C": "paralysis of the facial muscles, loss of taste and lacrimation.",
"D": "paralysis of the facial muscles, loss of taste, lacrimation and decreased salivation."
}
>> medrag = MedRAG(llm_name="OpenAI/gpt-3.5-turbo-16k", rag=True, retriever_name="MedCPT", corpus_name="PubMed")
>> answer, snippets, scores = medrag.answer(question=question, options=options, k=32) # scores are given by the retrieval system
```
