AntConc - N-grams analysis
Channel: CorpusLingAnalysis
Date: 2011-06-16

A screencast showing you how to search a corpus for N-grams using the software AntConc.

Notes

Software used: AntConc3.2.1 -- website: http://www.antlab.sci.waseda.ac.jp/antconc_index.html 

At the start of the video I mention that I assume that a word list has already been generated. Just to clarify: you don't have to generate a word list before generating n-grams. 
In this video I press 'Start' after choosing different sort options. However, if you have a big corpus, it will take a long time to regenerate the results, so a better method is to just click 'Sort', because then the software can just resort the already generated results.

Acknowledgments

My thanks go to Bethany Stanford who collected the corpus used in this video (15 speeches given by Barack Obama over the course of his election campaign which ran from 2007 to his subsequent election and inauguration in 2009). My thanks also go to Laurence Anthony for useful feedback on this video which I have incorporated in the notes above.
