Ruigi

Ruigi is similarity calculation library, which is implemented by Ruby.

Now, only support TF-IDF and cosine similarity.

Add this line to your application's Gemfile:

gem 'ruigi'

And then execute:

$ bundle

Or install it yourself as:

$ gem install ruigi

array of words -> Ruigi::Document

words = ["word1", "word2", ... , "wordN"]
document1 = Ruigi::Document.new(words)

Make a Model from documents of array

corpus = [document1, document2, ... , documentN] # each element's type is Ruigi::Document.
model = Ruigi::Model.new(corpus)

You can get feature vector for each document and calculate similarity between document.

model.feature_vector_of(0) # => return feature vector of 0th document

etc...
