Natural Language Processing

Some of you were interested in the visualization tools for natural
language processing of twitter feeds that I showed today as part of
the bonus session (as part of the grand finale).

The R code for producing wordclouds and undirected graphs based on
collocation of terms in each tweet of the twitter corpus is uploaded
in the NLP sub-folder under R code. The graphs that I showed in class
are attached (you can make your own Christmas cards this year using
MSAN 602 analytics code).  These codes should run without any edits
and can be used for Q2 of Assignment 6 (which is a bonus question for
extra credit).

The R code that I showed in class for creating directed graphs from
adjacency matrices (needed for Q1 of Assignment 6) is in the igraph
sub-folder under R code. This code also shows how to call the
page-rank algorithm which we covered in class today together with the
HITS algorithm.
