Natural Language Inference (NLI)
Shock: work of almost nine years at PARC was out of reach
when I left in 2008
I gave a talk at SRI proposing to redo it all, open source
(Bridges, ENTCS2011)
Pleased to report that almost all of it is now available
open-source, redone from scratch, using new techniques
