Sample this: Me: So that's the marshmallow but you're going to eat it with this graham cracker and chocolate. [My son looks at me like I am the dumbest person alive.] Sebastian: No, I'm going to eat it with my MOUTH.[End of play.] That's from "S'MORES. A Real-Life One-Act Play", capture of a conversation between Hamilton impresario Lin-Manuel Miranda which his young son Sebastian. In that brief interaction, young Sebastian Miranda inadvertently hit upon a kind of ambiguity that reveals a great deal about how people learn and process language -- and how we might teach computers to do the same. The misinterpretation on which the s'mores story hinges is hiding in the humble preposition with. Imagine the many ways one could finish this sentence: I'm going to eat this marshmallow with ... If you're in the mood for s'mores, then "graham cracker and chocolate" is an appropriate object of the preposition with. But if you want to split the marshmallow with a friend, you could say you're going to eat it "with my buddy Charlie." The Atlantic elaborates: Somehow speakers of English master these many possible uses of the word with without anyone specifically spelling it out for them. At least that's the case for native speakers -- in a class for English as a foreign language, the teacher likely would tease apart these nuances. But what if you wanted to provide the same linguistic education to a machine? As it happens, just days after Miranda sent his tweet, computational linguists presented a conference paper exploring exactly why such ambiguous language is challenging for a computer-based system to figure out. The researchers did so using an online game that serves as a handy introduction to some intriguing work currently being done in the field of natural language processing (NLP). The game, called Madly Ambiguous , was developed by the linguist Michael White and his colleagues at Ohio State University. In it, you are given a challenge: to stump a bot named Mr. Computer Head by filling the blank in the sentence Jane ate spaghetti with ____________. Then the computer tries to determine which kind of with you intended. Playful images drive the point home. In the sentence Jane ate spaghetti with a fork [Editor's note: check the article on The Atlantic for corresponding images], Mr. Computer Head should be able to figure out that the fork is a utensil, and not something that is eaten in addition to the spaghetti. Likewise, if the sentence is Jane ate spaghetti with meatballs, it should be obvious that meatballs are part of the dish, not an instrument for eating spaghetti.
