Then what does this mean?

Did I read that wrong?

I feel like you guys are speaking in a different language here. Maybe
I'm just behind on a few things, but I got lost in all of the EM, OPT,
JET, conf, k5, p5 references. Is there lexicon reference somewhere, so
I can match this stuff up to the DRLVM documentation on the web site?
Is the web site the most up-to-date reference for this [1]?
