See wiki: Cosine Similarity Here is the formula: Given two vectors A and B with the same size, calculate the cosine similarity. Return 2.0000 if cosine similarity is invalid (for example A = [0] and B = [0]). Example Given A = [1, 2, 3], B = [2, 3 ,4]. Return 0.9926. G...
The class shown below parsed the text documents and split them into tokens. This class will communicate with TfIdf.java class to calculated TfIdf. It also calls CosineSimilarity.java class to calculated the similarity between the passed documents. ...

The vector functions of the form function(query, doc[field]) are deprecated, and the form function(query, field) should be used instead. For example, cosineSimilarity(query, doc[field]) is replaced by cosineSimilarity(query, field).Disallow use of the nGram and edgeNGram tokenizer namesThe...
