# Dataset Description

## Dataset Summary

The NeedleBench dataset is a part of the OpenCompass project, designed to evaluate the capabilities of large language models (LLMs) in processing and understanding long documents. It includes a series of test scenarios that assess models' abilities in long text information extraction and reasoning. The dataset is structured to support tasks such as single-needle retrieval, multi-needle retrieval, multi-needle reasoning, and ancestral trace challenges.

</div>

## Supported Tasks and Primary Languages

- **Single-Needle Retrieval Task (S-RT)**: Extracting a single key piece of information from a long text.
- **Multi-Needle Retrieval Task (M-RT)**: Retrieving multiple related pieces of information from long texts.
- **Multi-Needle Reasoning Task (M-RS)**: Extracting and utilizing multiple key pieces of information for comprehensive understanding.
- **Ancestral Trace Challenge (ATC)**: Handling multi-layer logical challenges in real long texts.

The dataset supports multiple languages, including English and Chinese, as indicated by the presence of files like `multi_needle_reasoning_en.json` and `multi_needle_reasoning_zh.json`.


## Potential Use Cases

The NeedleBench dataset can be used to evaluate and compare the performance of different large language models in tasks involving long text processing, information extraction, and reasoning. It is useful for researchers and developers working on models that need to handle complex queries on extensive documents.

## Evaluation

Please follow the provided guidelines in the [OpenCompass documentation](https://opencompass.readthedocs.io/en/latest/advanced_guides/needleinahaystack_eval.html) to set up the environment, configure the dataset, and run evaluations.

## Additional Information
