codelibs / minhash Goto Github PK

On README.md you put this case:

// Compare a different text.
String text2 = "Solr is the popular, blazing fast open source enterprise search platform";
byte[] minhash2 = MinHash.calculate(analyzer, text2);
assertEquals(0.453125f, MinHash.compare(minhash, minhash2));

Please, help-me to understand this algorithm. Why the compare of two very different string the value is 0.453125f. Why not a number more near to 0?

Thanks

Hi, I've been learning to use this code recently. Can I think this code as the following three steps? First, we use lucene to generate text sets. Then we use a family of hash functions to obtain the minhash values. Finally we reduce the minhash value length to b-bit. That why we finally got a num* hashbit bits minhash. Am I right? I would appreciate it if you could reply this question.

The code
String text = "新冠疫苗效果不错"; byte[] minhash = calculateMinHash(text); String text1 = "每天吃饭呀哈哈哈"; byte[] minhash1 = calculateMinHash(text1); float score1 = MinHash.compare(minhash, minhash1);
the result is "0.546875"
you readme result below 0.5 is not simolarlity
But now ,The two text is not simolarlity.But result has been greater than 0.5.
If I use have problem ,Can you help me. Thanks

What goes in "..." for Tokenizer in the example you wrote in README.md?
I would like to replicate the example but I am confused there.
Thanks.
