Introduction. For many practical purposes it is not necessary to construct a complete parse tree for a sentence. Chunk parsing, also known as partial parsing, light parsing, or just chunking, is an approach in which the parser assigns incomplete syntactic structure to the phrase.The most common use of chunking is in information extraction and message understanding, where the content of a text NLTK: The Natural Language Toolkit Steven Bird Department of Computer Science and Software Engineering University of Melbourne Victoria 3010, Australia sb@csse.unimelb.edu.au Edward Loper Department of Computer and Information Science University of Pennsylvania Philadelphia PA 19104-6389, USA edloper@gradient.cis.upenn.edu Abstract

Language Identification using NLTK February 29, 2016 the TextCat algorithm calculates the “closeness” between each language and the profile sample by using an intuitive metric it calls the “out-of-place” measure. The out-of-place measure is a simple rank statistic calculating how far out of place a trigram in one profile is from
