Text::NSP - Extract collocations and Ngrams from text

The Ngram Statistics Package (NSP) is a collection of perl modules that aid in analyzing Ngrams in text files. We define an Ngram as a sequence of 'n' tokens that occur within a window of at least 'n' tokens in the text; what constitutes a "token" ca...

Text::NSP::Measures - Perl modules for computing association scores of Ngrams. This module provides the basic framework for these measures.

Introduction These modules provide perl implementations of mathematical functions (association measures) that can be used to interpret the co-occurrence frequency data for Ngrams. We define an Ngram as a sequence of 'n' tokens that occur within a win...
