Stack Overflow 相关问题算法 [英] Stack Overflow Related questions algorithm

问题描述

输入标题后出现的相关问题，以及查看问题时右侧栏中的问题似乎都在暗示非常贴切的问题.

The related questions that appear after entering the title, and those that are in the right side bar when viewing a question seem to suggest very apt questions.

Spolsky 在一次演讲中说，Stack Overflow 只对它进行 SQL 搜索，没有使用特殊算法.

Stack Overflow only does a SQL search for it and uses no special algorithms, said Spolsky in a talk.

在这种情况下，有什么算法可以给出好的答案.在这种情况下如何进行数据库搜索?使标题可搜索并搜索关键字或搜索标签和那些投票最多的问题?

What algorithms exist to give good answers in such a case. How do U do database search in such a case? Make the title searchable and search on the keywords or search on tags and those questions with many votes on top?

推荐答案

相关问题侧边栏将建立在每个问题的标签上(可能通过根据标签重叠对它们进行排名，所以 5 个共同的标签 > 4 个共同的标签等等).

The related questions sidebar will be building on the tags for each question (probably by ranking them based on tag overlap, so 5 tags in common > 4 tags in common etc).

其余的将建立在适用于自然语言处理的启发式和算法之上.这些在通用语言中通常不是很好，但是一旦词汇量减少到单个技术领域(例如编程)，它们中的大多数都非常好.

The rest will be building on heuristics and algorithms suitable for natural language processing. These aren't normally very good in general purpose language, but most of them are VERY good once the vocabulary is reduced down to a single technical area such as programming.
