138K Videos – Entity Interaction Dataset for Video Understanding

This dataset contains 138,172 video clips covering diverse real-world scenes and entity-interaction relationships. Each video clip includes keyframes that represent important entity interactions and their corresponding relationships. The annotation files provide entity types, bounding boxes, and interaction labels for relationship triples identified in the keyframes. Each relationship can be represented as a structured triple: (entity1, entity2, interaction). This dataset can be used for video understanding task.

Long Context Reasoning Dataset – Multi-Language (EN/CH/KR) Benchmark for LLM Evaluation

This dataset is designed to tackle the core weaknesses of today's large language models when it comes to processing long documents and performing complex reasoning. It consists of 7,500 high-quality training examples across three languages—Chinese, English, and Korean. Each instance is built around a long-text passage and includes questions that require synthesizing information across paragraphs and documents, while following multi-step logical chains. The goal is to offer a thorough and rigorous evaluation framework that tests a model's ability to perceive long-range context, retrieve relevant information, construct sound reasoning paths, and trace evidence back to its source.
