### Dataset Summary |
|
|
|
The ability to recognize analogies is fundamental to human cognition. Existing benchmarks to test word analogy do not reveal the underneath process of analogical reasoning of neural models. Holding the belief that models capable of reasoning should be right for the right reasons, we propose a first-of-its-kind Explainable Knowledge-intensive Analogical Reasoning benchmark (E-KAR). Our benchmark consists of 1,655 (in Chinese) and 1,251 (in English) problems sourced from the Civil Service Exams, which require intensive background knowledge to solve. More importantly, we design a free-text explanation scheme to explain whether an analogy should be drawn, and manually annotate them for each and every question and candidate answer. Empirical results suggest that this benchmark is very challenging for some state-of-the-art models for both explanation generation and analogical question answering tasks, which invites further research in this area. |
|
|
|
### Supported Tasks and Leaderboards |
|
|
|
- `analogical-qa`: The dataset can be used to train a model for analogical reasoning in the form of multiple-choice QA. |
|
- `explanation-generation`: The dataset can be used to generate free-text explanations to rationalize analogical reasoning. |
|
|
|
This dataset supports two task modes: EASY mode and HARD mode: |
|
- `EASY mode`: where query explanation can be used as part of the input. |
|
- `HARD mode`: no explanation is allowed as part of the input. |
|
|
|
### Languages |
|
|
|
This dataset is in Chinese, with its [English version](https://huggingface.co/datasets/Jiangjie/ekar_english). |

## Considerations for Using the Data |
|
|
|
### Social Impact of Dataset |
|
|
|
The purpose of this dataset is to help develop analogical reasoning systems that are right for the right reasons. |
|
|
|
### Discussion of Biases |
|
|
|
This dataset is sourced and translated from the Civil Service Examinations of China. Therefore, it may contain information biased to Chinese culture. |
|
|
|
### Other Known Limitations |
|
|
|
1. The explanation annotation process in E-KAR (not the EG task) is mostly post-hoc and reflects only the result of reasoning. Humans solve the analogy problems in a trial-and-error manner, i.e., adjusting the abduced source structure and trying to find the most suited one for all candidate answers. Therefore, such explanations cannot offer supervision for intermediate reasoning. |
|
|
|
2. E-KAR only presents one feasible explanation for each problem, whereas there may be several. |
