# BiomixQA Dataset
## Overview
BiomixQA is a curated biomedical question-answering dataset comprising two distinct components:
1. Multiple Choice Questions (MCQ)
2. True/False Questions
This dataset has been utilized to validate the Knowledge Graph based Retrieval-Augmented Generation (KG-RAG) framework across different Large Language Models (LLMs). The diverse nature of questions in this dataset, spanning multiple choice and true/false formats, along with its coverage of various biomedical concepts, makes it particularly suitable for assessing the performance of KG-RAG framework.
Hence, this dataset is designed to support research and development in biomedical natural language processing, knowledge graph reasoning, and question-answering systems.
## Dataset Description
- **Repository:** https://github.com/BaranziniLab/KG_RAG
- **Paper:** [Biomedical knowledge graph-optimized prompt generation for large language models](https://arxiv.org/abs/2311.17330)
- **Point of Contact:** [Karthik Soman](mailto:[email protected])
## Dataset Components
### 1. Multiple Choice Questions (MCQ)
- **File**: `mcq_biomix.csv`
- **Size**: 306 questions
- **Format**: Each question has five choices with a single correct answer
### 2. True/False Questions
- **File**: `true_false_biomix.csv`
- **Size**: 311 questions
- **Format**: Binary (True/False) questions
## Potential Uses
1. Evaluating biomedical question-answering systems
2. Testing natural language processing models in the biomedical domain
3. Assessing retrieval capabilities of various RAG (Retrieval-Augmented Generation) frameworks
4. Supporting research in biomedical ontologies and knowledge graphs
## Performance Analysis
We conducted a comprehensive analysis of the performance of three Large Language Models (LLMs) - Llama-2-13b, GPT-3.5-Turbo (0613), and GPT-4 - on the BiomixQA dataset. We compared their performance using both a standard prompt-based approach (zero-shot) and our novel Knowledge Graph based Retrieval-Augmented Generation (KG-RAG) framework.
### Performance Summary
Table 1: Performance (accuracy) of LLMs on BiomixQA datasets using prompt-based (zero-shot) and KG-RAG approaches (For more details, refer [this](https://arxiv.org/abs/2311.17330) paper)
| Model | True/False Dataset | | MCQ Dataset | |
|-------|-------------------:|---:|------------:|---:|
| | Prompt-based | KG-RAG | Prompt-based | KG-RAG |
| Llama-2-13b | 0.89 ± 0.02 | 0.94 ± 0.01 | 0.31 ± 0.03 | 0.53 ± 0.03 |
| GPT-3.5-Turbo (0613) | 0.87 ± 0.02 | 0.95 ± 0.01 | 0.63 ± 0.03 | 0.79 ± 0.02 |
| GPT-4 | 0.90 ± 0.02 | 0.95 ± 0.01 | 0.68 ± 0.03 | 0.74 ± 0.03 |
### Key Observations
1. **Consistent Performance Enhancement**: We observed a consistent performance enhancement for all LLM models when using the KG-RAG framework on both True/False and MCQ datasets.
2. **Significant Improvement for Llama-2**: The KG-RAG framework significantly elevated the performance of Llama-2-13b, particularly on the more challenging MCQ dataset. We observed an impressive 71% increase in accuracy, from 0.31 ± 0.03 to 0.53 ± 0.03.
3. **GPT-4 vs GPT-3.5-Turbo on MCQ**: Intriguingly, we observed a small but statistically significant drop in the performance of the GPT-4 model (0.74 ± 0.03) compared to the GPT-3.5-Turbo model (0.79 ± 0.02) on the MCQ dataset when using the KG-RAG framework. This difference was not observed in the prompt-based approach.
- Statistical significance: T-test, p-value < 0.0001, t-statistic = -47.7, N = 1000
4. **True/False Dataset Performance**: All models showed high performance on the True/False dataset, with the KG-RAG approach yielding slightly better results across all models.
