我想使用光标光标页从基于最喜欢的相似点的数据库中获取批注, 从最喜欢的类似点到最不喜欢它们, 并将其装入一个批注部分。 此功能旨在反映 Youtube S Top 批注 。 例如, 我加载一组批注, 并使用最后一个批注作为光标 。 可以说最后一个批注有 10 个喜欢 。 下一组要加载的批注应该小于或等于 10 个类似点 。 出现的问题是, 在我加载下一组批注之前, 下一组批注可能比光标更喜欢( 例如从 9 到 12 ) 的批注, 以及我已经加载和装入的批注少一些类似点( 例如从 14 到 7 ) 的批注。 所以当我加载下一组批注时, 那些已加载的批注可能会排除最近获得的类似和( 或) 已经加载的批注。
我尝试了Youtube S Top 批注的实验,看看它是否存在同样的问题,但我没有得到重复的或错过的评论。我知道ytube S Top 批注很可能使用复杂的算法来确定顶级评论,而不只是基于类似数字。是否有一种算法已经解决这个问题了?Youtube似乎已经解决了这个问题,但我不知道它们是如何解决这个问题的。我无法找到解决问题的有效办法。
坦率地说,我对这种特征没有实践经验。
