I\'m searching about a sort of hash function to index similar text. So for example if we have two very long text called \"A\" and \"B\" where A and B differ not so much, then the hash function (called
I\'m trying to use TF-IDF to sort documents into categories.I\'ve calculated the tf_idf for some documents, but now when I try to calculate the Cosine Similarity between two of these documents I get a
I am doing some data-mining on time series data. I need to calculate the distance or开发者_如何学运维 similarity between two series of equal dimensions. I was suggested to use Euclidean distance, Cos
There is a function similar_text() in the PHP library.The documentation (http://php.net/manual/en/function.similar-text.php) tells me that \"This calculates the similarity between two strings as descr
What methods are there to get JPQL to match similar strings? By similar I mean: Contains: search string is found within the string of the matches entity
Is it possible to configure Solr so that the document similarity score would be in the range for e开发者_如何学Cxample from 0 (no match) to 1 (complete document and query match).
Using Python, I\'m computing cosine similarity across items. given event data that represents a purchase (user,item), I have a list of all items \'bought\' by my users.
In the field of Data Mining,开发者_如何学编程 is there a specific sub-discipline called \'Similarity\'? If yes, what does it deal with. Any examples, links, references will be helpful.
I am finding cosine similarity between documents.. I did it like this D1=(8,0,0,1) where 8,0,0,1 are the tf-idf scores of the terms t1, t2, t3 , t4
My program uses clustering to produce subsets of similar items and then uses the cosine similarity measure as a method of determining how similar the clusters are. For instance if user 1 has 3 cluster
