First of all, what is NLP?
NLP is a subfield of linguistics and artificial intelligence. It studies how human languages are understood, or processed, by its users, and it tries to model them. Although I do not work on NLP, my research on temporal semantics can be extended to NLP if I ever decide to do so.
So what are some of the research that people doing NLP do?
The research includes pronoun resolution, temporal interpretation, discourse resolution, among other things. But instead of boring my readers with these technical terms, I'd just introduce some of the linguistic puzzles that I have come across the web.
Observe the following two sentences:
In these two sentences, the antecedent of theyare different. In the first sentence, it refers back to the monkeys, but in the second sentence, it refers back to the bananas. The syntax of the two sentences are the same, and the rhetorical relations that exist between the two clauses are also the same (Both are Explanation). But our world knowledge (also known as Knowledge Base) tells us that monkeys cannot be over-ripe and bananas cannot be hungry, thus, it refers back to the proper noun phrase.
This sentence has multiple interpretations. 1) Tiem moves quickly just like an arrow does. 2) Measure the speed of flying insects like you would measure that of an arrow. You should time flies like you would an arrow. 3) Measure the speed of flying insects like an arrow would. Time flies in the same way that an arrow would time them. 4) Measure the speed of flying insects that are like arrows. Time those flies that are like arrows. 5) A type of flying insect "time-fly" enjoys arrows. Fruit flies like a banana.
This one is for you. Who or what is pretty? Who or what is little?
Finally, let me share the last of my Telephone Series for your enjoyment.
