Kuaipedia is developed by KwaiKEG, collaborating with HIT and HKUST. It is the world's first large-scale multi-modal short-video encyclopedia where the primitive units are items, aspects, and short videos.
- Items is a set of entities and concepts, such as Shiba Inu, Moon and Galileo Galilei, which can be edited at one Wikipedia page. An item may have a title, a subtitle, a summary, attributes, and other detailed information of the item.
- Aspects is a set of keywords or keyphrases attached to items. Those keywords are used to describe specific aspects of the item. For example, "selection", "food-protecting", "color" of item Shiba Inu, or "formation", "surface conditions", "how-to-draw" of item Moon.
- Videos is a set of short-videos whose duration may not exceed 5 minutes. In this paper, we only focus on knowledge videos we detected, Where we follow OECD to define knowledge as:
- Know-what refers to knowledge about facts. E.g. How many people live in New York?
- Know-why refers to scientific knowledge of the principles and laws of nature. E.g. Why does the earth revolve around the sun?
- Know-how refers to skills or the capability to do something. E.g. How to cook bacon in the oven.
Please refer to the paper for more details.
