# Card-660 Dataset

This is the **Card-660** (Cambridge Rare Word) dataset, converted to Hugging Face `datasets` format.

## Description
Card-660 is a benchmark for evaluating semantic similarity models, specifically focusing on **rare and infrequent words**. It contains 660 word pairs annotated by experts. It was designed to solve the issues of low inter-annotator agreement found in other rare-word datasets (like RW).

## Columns
- `word1`: First word of the pair
- `word2`: Second word of the pair
- `similarity`: Human-annotated similarity score (scale typically 0-4 or 0-10)

## Usage
```python
from datasets import load_dataset
dataset = load_dataset("Yuti/Card-660")
