ChatKBQA: A Generate-then-Retrieve Framework for Knowledge Base Question Answering with Fine-tuned Large Language Models

Paper Blog Tool Report Report PWC PWC

Overview

General Setup

Environment Setup

conda create -n chatkbqa python=3.8
conda activate chatkbqa
pip install torch==1.13.1+cu117 torchvision==0.14.1+cu117 torchaudio==0.13.1 --extra-index-url https://download.pytorch.org/whl/cu117
pip install -r requirement.txt

Freebase KG Setup

Below steps are according to Freebase Virtuoso Setup.

How to install virtuoso backend for Freebase KG.

  1. Clone from dki-lab/Freebase-Setup:
cd Freebase-Setup
  1. Processed Freebase Virtuoso DB file can be downloaded from Dropbox or Baidu Netdisk (WARNING: 53G+ disk space is needed):
tar -zxvf virtuoso_db.zip
  1. Managing the Virtuoso service:

To start service:

python3 virtuoso.py start 3001 -d virtuoso_db

and to stop a currently running service at the same port:

python3 virtuoso.py stop 3001

A server with at least 100 GB RAM is recommended.

Download FACC1 mentions for Entity Retrieval.

  • Download the mention information (including processed FACC1 mentions and all entity alias in Freebase) from OneDrive or Baidu Netdisk to data/common_data/facc1/.

Dataset

Experiments are conducted on 2 KBQA benchmarks WebQSP, CWQ.

WebQSP

WebQSP dataset has been downloaded under data/WebQSP/origin.

Data Processing

(1) Parse SPARQL queries to S-expressions

  • WebQSP:

Run python parse_sparql_webqsp.py and the augmented dataset files are saved as data/WebQSP/sexpr/WebQSP.test[train].json.

  • CWQ:

Run python parse_sparql_cwq.py and the augmented dataset files are saved as data/CWQ/sexpr/CWQ.test[train].json.

(2) Prepare data for training and evaluation

  • WebQSP:

Run python data_process.py --action merge_all --dataset WebQSP --split test and python data_process.py --action merge_all --dataset WebQSP --split train. The merged data file will be saved as data/WebQSP/generation/merged/WebQSP_test[train].json.

Run python data_process.py --action get_type_label_map --dataset WebQSP --split train. The merged data file will be saved as data/WebQSP/generation/label_maps/WebQSP_train_type_label_map.json.

  • CWQ:

Run python data_process.py --action merge_all --dataset CWQ --split test and python data_process.py --action merge_all --dataset CWQ --split train. The merged data file will be saved as data/CWQ/generation/merged/CWQ_test[train].json.

Run python data_process.py --action get_type_label_map --dataset CWQ --split train. The merged data file will be saved as data/CWQ/generation/label_maps/CWQ_train_type_label_map.json.

(3) Prepare data for LLM model

  • WebQSP:

Run python process_NQ.py --dataset_type WebQSP. The merged data file will be saved as LLMs/data/WebQSP_Freebase_NQ_test[train]/examples.json.

  • CWQ:

Run python process_NQ.py --dataset_type CWQ The merged data file will be saved as LLMs/data/CWQ_Freebase_NQ_test[train]/examples.json.

Fine-tuning, Retrieval and Evaluation

The following is an example of LLaMa2-7b fine-tuning and retrieval (num_beam = 15) on WebQSP and LLaMa2-13b fine-tuning and retrieval (num_beam = 8) on CWQ, respectively. We also provide a variety of LLMs (including LLaMa2-7b, LLaMa2-13b, ChatGLM2-6b, Baichuan2-7b, Baichuan2-13b) fine-tuning scripts (num_beam = 8).

(1) Train and test LLM model for Logical Form Generation
