北京时间4月1日消息,Facebook动态消息(News Feed)因为存在重大排序错误,过去6个月一直推送“糟糕”内容。由于排序算法存在漏洞,动态消息抬高了虚假、暴力信息的权重。

去年10月,工程师发现推送有问题,当时动态消息中的虚假信息明显增多。虚假信息本来是经过事实核查员审查过的,应该早早得到抑制,但这些信息却四处传播。工程师找不到根本原因,只能眼睁睁看着虚假信息持续发酵,几个星期后平息,然后复发,最终工程师才发现是排序有问题,并于3月11日修复。

内部文档显示,该技术问题最早可追溯到2019年,但直到2021年10月才造成重大影响。Meta新闻发言人乔·奥斯本(Joe Osborne)说:“我们追踪根本原因,最终发现是软件有漏洞,然后进行了修复。漏洞不会给我们的评估标准造成任何有意义的长远影响。”

多年来,Facebook一直鼓吹公司开发的降序系统,认为它可以提高动态消息的质量,随着自动系统的优化未来能处理更多种类的内容。很明显,Facebook系统仍然不完美。
