我需要将每个标题与其他4个具有共同词汇的标题分组。例如，如果我愿意将4个cds分组，并在字符串中包含单词BEETHOVEN和MOZART。
但是，我不想指定它应该分组的单词。我希望以某种人工智能的方式完成这项工作
这就是我认为算法应该是这样的：
有没有人知道任何明智的分组方法？
答案 0 :(得分：2)
Re（2），你想要的东西被称为“停用词” - 例如，在NLTK（这是Python，但我想会有C＃等价物），在其出色的在线书中每chapter 2，< / p>
>>> from nltk.corpus import stopwords
>>> stopwords.words('english')
['a', "a's", 'able', 'about', 'above', 'according', 'accordingly', 'across',
'actually', 'after', 'afterwards', 'again', 'against', "ain't", 'all', 'allow',
'allows', 'almost', 'alone', 'along', 'already', 'also', 'although', 'always',
...]
我引用的这本书也可以帮助您解决问题1，但第3点实际上是一个不同的领域 - 聚类。您需要一种非常特殊的聚类（指定且相同的聚类大小），因此现有算法可能不适合您，但根据您提及的内容设计一些并不太难。
基本上你希望每个单词值得一个“得分”，对于英语中较少的单词（和NLTK，或者C＃中任何等效强大的自然语言处理工具包，当然可以帮助你）更高 - - 减去例如，单词频率的对数可以是一个开始。
根据您提到的规范，您只需要对至少五个文档中出现的不间断单词进行评分，因此有意义单词的数量应该非常少，并且详尽的搜索甚至可能是可行的。
事实上，最大的问题可能是另一个问题 - 如果有一组不到5个文档的话，不与任何其他人共同拥有任何不间断的词汇？这种情况发生的可能性表明你必须放松某些方面的规范（因为我对你的应用程序一无所知我当然不能给出具体的建议，但它可能是任何允许具有多个不同于5的文档的组，放宽分组标准等等。
或者，您是否愿意仅仅诊断某些情况是否存在实际满足您的严格约束的情况，并提供错误消息而不是任何结果？
