kuaishou

The dataset is a large-scale industrial dataset collected from Kuaishou, containing user interaction data with click-through as labels. The dataset has a maximum history length of 100,000 items for clustering life-cycle user behavior.

We propose PLPM, a new task for selecting optimal landing pages upon user entry. Our solution, KLAN, models static and dynamic user interests and is successfully deployed on Kuaishou, improving DAU and user lifetime

Health science popularization short videos have become one of the main sources of acquiring disease-related information. However, the quality of such videos on popular short video platforms varies considerably. This study aims to evaluate the quality of the health science popularization short videos about cerebrovascular diseases on two popular short video platforms (TikTok and Kuaishou) in China.

Cervical cancer is a significant global health concern with over 662,000 new cases and approximately 349,000 deaths in 2022. Despite the clear benefits of screening, a portion of the population remains unaware of its importance. In China, short video platforms such as Kuaishou, Bilibili, and TikTok host numerous related videos, but the quality varies significantly.

Social media engagement among older adults has surged worldwide, with China's older users exceeding 120 million in 2023. However, research remains disproportionately focused on youth. Critically, the dose-response relationship between use intensity and mental health in this population is poorly quantified, especially in rapidly aging societies such as China, where 23% of the population will be aged ≥65 years by 2035.

Lumbar disc herniation is a common chronic condition among working people. In China, the number of popular scientific videos on health and disease knowledge is increasing on short video platforms, but there is still a lack of sufficient research to evaluate the quality of these short videos. The main objective of this study was to evaluate the quality, reliability, and content completeness of lumbar disc herniation related videos posted on four major short video platforms in China.
