Query: COIN: A Large-scale Dataset for Comprehensive Instructional Video
  Analysis   There are substantial instructional videos on the Internet, which enables us
to acquire knowledge for completing various tasks. However, most existing
datasets for instructional video analysis have the limitations in diversity and
scale,which makes them far from many real-world applications where more diverse
activities occur. Moreover, it still remains a great challenge to organize and
harness such data. To address these problems, we introduce a large-scale
dataset called "COIN" for COmprehensive INstructional video analysis. Organized
with a hierarchical structure, the COIN dataset contains 11,827 videos of 180
tasks in 12 domains (e.g., vehicles, gadgets, etc.) related to our daily life.
With a new developed toolbox, all the videos are annotated effectively with a
series of step descriptions and the corresponding temporal boundaries.
Furthermore, we propose a simple yet effective method to capture the
dependencies among different steps, which can be easily plugged into
conventional proposal-based action detection methods for localizing important
steps in instructional videos. In order to provide a benchmark for
instructional video analysis, we evaluate plenty of approaches on the COIN
dataset under different evaluation criteria. We expect the introduction of the
COIN dataset will promote the future in-depth research on instructional video
analysis for the community.
