Finite State Automata in Luceneby Mike McCandless

From the post:

Lucene Revolution 2012 is now done, and the talk Robert and I gave went well! We showed how we are using automata (FSAs and FSTs) to make great improvements throughout Lucene.

You can view the slides here.

This was the first time I used Google Docs exclusively for a talk, and I was impressed! The real-time collaboration was awesome: we each could see the edits the other was doing, live. You never have to “save” your document: instead, every time you make a change, the document is saved to a new revision and you can then use infinite undo, or step back through all revisions, to go back.

Finally, Google Docs covers the whole life-cycle of your talk: editing/iterating, presenting (it presents in full-screen just fine, but does require an internet connection; I exported to PDF ahead of time as a backup) and, finally, sharing with the rest of the world!

I must confess to disappointment when I read at slide 23 that “multi-token synonyms mess up graph.”

Particularly since I suspect that not only do synonyms need to be “multi-token” but “multi-dimensional” as well.
