My FREE Analytic Tools for Excel
are now combined into a single suite,
which runs on Office 2010 or newer
My free Analytic Tools for Excel now include a simple text-mining and display tool - WordMap,
which will "mine" the text from multiple documents for "nuggets" of meaning, and display them in a
map that represents not only frequency, but also adjacency of the
words in the original documents.
So, what exactly is a WordMap?
Here are two WordMaps representing the content of the songs by
Taylor Swift and Randy Travis (after automatically mining the lyrics
for "nuggets" of content):
size of the font represents how frequently a word appears in the
documents (songs). Words than tend to appear in the same song are
positioned closer to each other, while words that are rarely used in
the same song are placed farther from each other (of course, some
"artistic license" is taken to avoid overlaps...). Can you see
difference between the two song-writers? Who is more religious?
are some WordMaps from Donald Trump's most influential (most
re-Tweeted) Tweets during the primaries, as the nominee from the GOP
and as President:
a more business-related context, here are the WordMaps for customer
reviews of hotels in Manhattan from one travel site, for business and
like my WordMaps? Why don't you produce your own? If you
have the text of multiple documents, my WordMap tool for Excel will automatically
produce (hopefully more interesting) maps like those above. You may download it here.
