# klue-tc-eval

> KLUE: Korean Language Understanding Evaluation — Sungjoon Park et al. (arXiv:2105.09680, 2021)

## What this evaluates

Evaluates a model's ability to classify Korean text into predefined topic categories, testing core semantic understanding and categorization capabilities in Korean.

## Datasets

- **KLUE-TC** — total ?; splits: train (-1), val (-1), test (-1); repo https://github.com/KLUE-benchmark/KLUE

## Metrics

- `Accuracy` **(primary)** — range: [0, 1]
  - The proportion of correctly predicted topic labels out of the total number of instances.

## Input / output format

**Input**: Korean text document or sentence.

**Output**: Predicted topic label.

## Scoring recipe

```python
def compute_accuracy(predictions, gold):
    correct = sum(1 for p, g in zip(predictions, gold) if p == g)
    return correct / len(gold)
```

## Common pitfalls

- Data leakage from pretraining corpora if test data overlaps with training sources.
- PII removal may alter text distribution and impact model performance.

## Evidence (verbatim from paper)

> KLUE introduces a comprehensive, ethically designed benchmark for Korean NLU with 8 tasks (Topic Classification, STS, NLI, NER, RE, DP, MRC, DST) built from scratch using diverse, copyright-respected corpora.
