+# The Wikipedia Corpus in MedRAG
+
+This HF dataset contains the chunked snippets from the Wikipedia corpus used in [MedRAG](https://arxiv.org/abs/2402.13178). It can be used for medical Retrieval-Augmented Generation (RAG).
+
+## Dataset Details
+
+### Dataset Descriptions
+
+As a large-scale open-source encyclopedia, Wikipedia is frequently used as a corpus in information retrieval tasks.
+We select Wikipedia as one of the corpora to see if the general domain database can be used to improve the ability of medical QA. 
+We downloaded the processed Wikipedia data from [HuggingFace](https://huggingface.co/datasets/wikipedia) and chunked the text using [LangChain](https://www.langchain.com/) as snippets with no more than 1000 characters. 
+This HF dataset contains our ready-to-use chunked snippets for the Wikipedia corpus, including 29,913,202 snippets with an average of 162 tokens.
+
+### Dataset Structure
+Each row is a snippet of Wikipedia, which includes the following features:
+
+- id: a unique identifier of the snippet
+- title: the title of the Wikipedia article from which the snippet is collected
+- content: the content of the snippet
+- 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/wikipedia
+```
+
+### 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="Wikipedia")
+>> answer, snippets, scores = medrag.answer(question=question, options=options, k=32) # scores are given by the retrieval system
