tfidf_cosine_cpp

Yang Gao's implementation of tf-idf text indexing scheme, predict doc similarity by cosine similarity. Refer to: http://en.wikipedia.org/wiki/Tf–idf; yet I use normalized tf instead of raw tf.

It can serve as a baseline for more complicated text indexing and retrieval models, such as topic model.
