NLP is about understanding. When you understands what has been said, you’ve learned, didn’t you?
I believe this is correct.
Right now, Grace is very very young and only has a small mastery of language.
But she can ‘understand’ (ok, whatever word you want to use), things like : “Sam took some money out of the bank because he was going to the Casino”
and respond when asked where Sam went. She will actually know that she assumed he actually made it to the casino (that is intention was to go to the casino).
Later she will handle if you said “no, he didn’t make it to the casino” and adjust her belief.
This weekend she will learn the difference between connecting main clause to a subordinate clause, not with “because” but instead with “if”.
“Jane will be angry if Jack went to the casino”
note that the subordinate clause, if taken in isolation, (“Jack went to the casino”) does NOT mean he actually DID go to the casino (because of “if” subordinate conjunction). Not like “Jane is angry because Jack went to the casino”.
So right now she knows that if subordinate conjunction is “because” (and yes, any other term like “since”, “cuz”, even “bc” (short form)) , and later even misspelled “becuase” ).
Later, abductive reasoning module will be added to allow her to handle things like, given the fact above, and user stating “Jane is angry.”, she may hypothesize , “Why, did Jack go to the casino ?” That should prove most interesting !
I don’t think Watson is doing NLP like Grace. I could be wrong, but many videos, the developers of Watson out right stated “Watson itself can’t read a page of text and understand it.”
Hans, agreed , Watson = very powerful key-word , statistics based search engine.
