在Youtube频道中为儿童描述视频、观众和广告
Characterizing videos, audience and advertising in Youtube channels for kids
摘要：
在线视频服务、短信系统、游戏和社交媒体服务在许多国家的年轻人和儿童中非常受欢迎。互联网上提供的大多数数字服务都是由广告资助的，这使得广告在儿童的日常生活中无处不在。为了了解基于广告的数字服务对儿童的影响，我们研究了YouTube儿童频道用户的集体行为，并展示了大量用户的人口统计数据。我们收集了来自美国和英国17个频道以及巴西24个频道的12，848个视频的数据。英语频道的观看次数超过370亿次。我们还收集了超过1400万条用户评论。基于文本分析和人脸识别工具的组合，我们在大样本用户中显示了种族和性别偏见的存在。我们还识别积极使用YouTube的儿童，尽管在大多数国家/地区，使用该服务的最低年龄为13岁。我们比较了这三个国家的用户行为，这三个国家代表了全球北方和南方的大量用户群体。
英文摘要：
Online video services, messaging systems, games and social media services are tremendously popular among young people and children in many countries. Most of the digital services offered on the internet are advertising funded, which makes advertising ubiquitous in children's everyday life. To understand the impact of advertising-based digital services on children, we study the collective behavior of users of YouTube for kids channels and present the demographics of a large number of users. We collected data from 12,848 videos from 17 channels in US and UK and 24 channels in Brazil. The channels in English have been viewed more than 37 billion times. We also collected more than 14 million comments made by users. Based on a combination of text-analysis and face recognition tools, we show the presence of racial and gender biases in our large sample of users. We also identify children actively using YouTube, although the minimum age for using the service is 13 years in most countries. We provide comparisons of user behavior among the three countries, which represent large user populations in the global North and the global South.
