测量文档集之间的相似性 [英] Measuring similarity between document sets

问题描述

出于说明目的，我们假设这是一个论坛服务.我需要计算每个用户的帖子之间的相似度"，这样结果将是这样的:

among posts by user A, similarity 60%
among posts by user B, similarity 20%
...

我正在处理多字节字符串，所以我想我在这里受搜索引擎的困扰.我们已经使用Solr，已经实现了更多的LikeThis，但是我不太确定如何构造查询.任何帮助表示赞赏！

For illustration purposes, let's assume this is a forum service. I need to calculate the "similarity" among each users' posts, so that the result would be something like:

among posts by user A, similarity 60%
among posts by user B, similarity 20%
...

I'm dealing with multibyte strings, so I guess I'm stuck with search engines here. We already use Solr, already have moreLikeThis implemented, but I'm not quite sure how to construct the query. Any help appreciated!
