什么算法将集合 A 中的每个元素映射到集合 B 中的最佳匹配？

【中文标题】什么算法将集合 A 中的每个元素映射到集合 B 中的最佳匹配？

【英文标题】：What algorithm maps each element from set A to it best match in set B?

【问题描述】：

我有两组字符串 A 和 B。

我想做一些看起来类似于搜索引擎为关键字搜索构建索引可能需要做的事情，但应用程序将实体从一个数据集映射到另一个键不同但相似的数据集。

更新：由于我下面的示例数据似乎与问题无关，所以我在最后粘贴了实际数据，但不确定它是否太长而无济于事。

甲乙 -------- -------- 福福 酒吧酒吧 - 美国 蝙蝠蝙蝠 宾果游戏 泽普泽 齐柏林飞艇 酒吧

我想遍历 A 的每个项目并将其与 B 的一个项目匹配。

结果：

Foo -> Foo
Bar -> Bar - US
Bat -> bat
Bing -> bing
Zep -> zepplin

我想知道是否已经有现有的方法来实现这一点。我记得曾经在从段落中提取摘要句子的上下文中阅读有关 Baysean 的内容或其他内容，但我不知道这是否可以应用。

我认为它必须有定义一些启发式的输入，但这似乎使它相当复杂。

【问题讨论】：

听上去像是 levenstein (sp?) 距离的工作

你不能改变你的例子，让左边的值实际上在集合 A 中，而右边的值在集合 B 中？它让我头疼。

我在 SO 上与其他程序员的互动越多，我就越觉得这些年来我开发了一种不太理想的思维方式......老实说，我不明白这是什么困惑，但是我一点也不怀疑它的存在

例如，您在结果中显示 Zip 和 zipplin，但在 A 或 B 中均未出现。此外，您没有说明为什么 Bar 转到 Bar - US 而不是 Bars。 -1

谢谢。我会澄清的。 zipplin 完全是我的错 - 这是一个错字。

【参考方案1】：

看我的回答here。

在尝试找到可以做的事情之前，您需要先定义自己想做什么。

什么算作“匹配”？

如果它只是一个不区分大小写的CONTAINS，那么它是微不足道的。 如果您需要考虑/排除某些标点，则只需将其从每个数据集中剥离以进行比较 匹配缩写？例如，您可能会查找将 inc 映射到 incorporated（您似乎正在使用公司名称） 拼写错误 - 查看 Levenstein 和其他 Edit distance algorithms 语音学/“听起来像” - 查看 SoundEx 和其他 Phonetic algorithms

您更喜欢误报还是误报？您需要达到多准确 - 这是第一次通过过滤器，之后可以手动完成少量操作，还是需要每次都正确的自动化过程？

它可以像你想要的那样复杂。

谢谢 - 你很好地表达/验证了我对答案的直觉基本上是......它属于一次性任务的类别，我试图获得最好的开始在我将工作交给实习生手动更正之前指出
