# Dataset Card for UnarXive E5 Index
This repository contains a **dense vector index** built using the [e5-large-v2](https://huggingface.co/intfloat/e5-large-v2) model on the **abstracts** of over 2.3 million arXiv papers in the [UnarXive 2024](https://huggingface.co/datasets/ines-besrour/unarxive_2024) dataset.
It is designed for **neural retrieval**, especially in **retrieval-augmented generation (RAG)** pipelines, scientific QA systems, and dense ranking models.
## What's Inside
- Dense embeddings of paper abstracts (`e5-large-v2`)
- Index format: FAISS (flat or HNSW depending on version)
- Each vector is associated with `paper_id`, `title`, and `abstract`
## Use Cases
- Dense retrieval in scholarly QA or chatbots
- Scientific search engines with semantic understanding
- RAG systems over structured academic corpora
- Paper similarity or clustering
