Dataset Card for KQA Pro

Dataset Summary

KQA Pro is a large-scale dataset of complex question answering over knowledge base. The questions are very diverse and challenging, requiring multiple reasoning capabilities including compositional reasoning, multi-hop reasoning, quantitative comparison, set operations, and etc. Strong supervisions of SPARQL and program are provided for each question.

Supported Tasks and Leaderboards

It supports knowlege graph based question answering. Specifically, it provides SPARQL and program for each question.

Knowledge Graph File

You can find the knowledge graph file kb.json in the original github repository. It comes with the format:

{
    'concepts':
    {
        '<id>':
        {
            'name': str,
            'instanceOf': ['<id>', '<id>'], # ids of parent concept
        }
    },
    'entities': # excluding concepts
    {
        '<id>': 
        {
            'name': str,
            'instanceOf': ['<id>', '<id>'], # ids of parent concept

How to run SPARQLs and programs

We implement multiple baselines in our codebase, which includes a supervised SPARQL parser and program parser.

In the SPARQL parser, we implement a query engine based on Virtuoso. You can install the engine based on our instructions, and then feed your predicted SPARQL to get the answer.

In the program parser, we implement a rule-based program executor, which receives a predicted program and returns the answer. Detailed introductions of our functions can be found in our paper.

How to submit results of test set

You need to predict answers for all questions of test set and write them in a text file in order, one per line. Here is an example:

Tron: Legacy
Palm Beach County
1937-03-01
The Queen
...

Then you need to send the prediction file to us by email caosl19@mails.tsinghua.edu.cn, we will reply to you with the performance as soon as possible. To appear in the learderboard, you need to also provide following information:

• model name
• affiliation
• open-ended or multiple-choice
• whether use the supervision of SPARQL in your model or not
• whether use the supervision of program in your model or not
• single model or ensemble model
• (optional) paper link
• (optional) code link
