It's because the name of the moon is "The Moon", not "Moon". I think SF writers sometimes pretend it's called "Luna" so it'll have a more interesting name.
Thanks! I'm indeed not native :)
In my own defense it "felt" like it was missing something. However I am confident there are many moons and just one Moon, our own.
Also, the answer is 1.62kN to 4.8kN, I know Wolfram doesn't employ a language model or anything of a sorts, but with all the other NLP magic I've seen I sort of expected a valid answer.
Bleh.. .English and it's weird grammar .. Sometimes I find it such a messed up language compared to my native tongue..... I guess it's the separation of modifiers and nouns that's part of the problem.
It shouldn't really be that difficult. If it's capable of structuring "How heavy is _ on the moon?" The answer would be start out the same way looking for weight of _.
It seems to me that these kinds of questions could be handled but require some adjustments or tuning more than we need fundamentally different approaches. We can't do everything at once so there's going to be simple things that don't work for quite a while.
I would expect any language model to be robust to minor errors like that though so I doubt it makes any difference.
