APTIE:A Multi-Task Information Extraction Chinese Dataset for APT Cyber Threat Intelligence

The dataset is designed to support Chinese-language information extraction in APT threat intelligence and covers three modules: entity recognition, relation extraction, and event extraction, as detailed below.

1. Entity Module: Provides JSONL files exported from the annotation tool, as well as entity annotation files following the BIO encoding standard, facilitating flexible use across different model architectures.

2. Relation Module: Contains detailed annotations of relations between entities and their type definitions, provided in a structured CSV format.

3. Event Module: Includes both JSONL files exported from the annotation tool and event annotation files in the standard format consistent with the DuEE dataset, supporting training and evaluation of mainstream event extraction methods.

All three sub-tasks are split into training, validation, and test sets, ensuring scientific rigor and reproducibility in model development and performance evaluation.
