(Originally posted in the INFORMS 2018 blog).

There are many ways to contemplate data. Shabbir Ahmed just tweeted a word cloud based on talks of the INFORMS 2018 Annual Meeting in Phoenix:

In this post, I will use a random walk instead. I wrote a piece of code that traverses talk titles to compute the frequency that each work is the first, the last, or the immediate successor of another word. This Markovian model can easily generate random titles but it is arguably not state-of-art, so why not using something more ellaborate like an LSTM? I wanted something complex enough to make sense while simple enough to generate unexpected outcomes. Otherwise, it would be boring to read them!

I believe that I can roughly classify the results that I got in four categories, which by decreasing frequency are the following:

- Non-sense.
- Awkward or boring statements.
- Long titles mixing the most commonly used terms (see “The buzzword bingo”).
- Somewhat plausible but unexpected titles (see “The interesting talks you will not see at INFORMS”).

### The interesting talks you will not see at INFORMS

These are the types of talks that I am looking for when I arrive every year:

- A Spatial Branch-and-Bound Algorithm via Retrospective Study

### Wrapping up

It will be no surprise if you found two or three consecutive words above that you used for your talk. To the best that I could, I tried avoiding examples that were too similar to any of the talks in the program. I hope that I managed to keep it that way.

Now, why did I call this piece of code an engine? Marketability! The following tweet is from a talk by Rama Ramakrishnan at a seminar in the MIT Operations Research Center:

Last but not least, INFORMS made my life a lot easier by sending me the data I needed. Special thanks to Mary Leszczynski!
