On: SLING: A Natural Language Frame Semantic Parser

[syllogism]

I'm not sure why you're thinking this was an industrial implementation? It's built on DRAGNN, which is pretty new, so that doesn't give much time for it to be in production. Also, if it were in production the blog post would surely say that -- instead it's quite clearly marked as an experimental system, for research. The lead author seems to be a researcher, too.

The whole thing feels like it is bits of code extracted or rewritten out of an existing system.

Take the whole Myelin JIT compiler. That's a pretty weird thing to build just for research into frame parsing.
