Description
Usage
Arguments
Value
Description
Returns a tf-idf sparse matrix given a document-term matrix.
This matrix is a DxT matrix, where D is the set of documents in a corpus and T are the unique terms in that corpus.
The matrix reflects a count of occurences of a given term in a given document.
Usage
1
tfidf(data_matrix)
Arguments
data_matrix
Sparse document-term matrix (generated with Matrix package)
Value
