There is a property of language, called "compositionality". It means that in any sentence, you could replace a word with a phrase with the same meaning, and the meaning of the sentence would stay the same. Let's look at the following two sentences:
I ate a carrot.
I ate a crunchy orange vegetable.
The meaning of these two sentences stays the same, while the phrasing and style change. Today's Artificial Intelligence algorithms working with language could not really capture compositionality.
The multiplayer game you are about to play is built around this property of language. We hope that the data we collect would help us build better, more human-like natural language processing systems. We did our best to make the game fun, but if it's not fun enough - know that you are helping science while playing.
During the second, Guess stage, we see sentences with substitutions by our opponents (in this case, Jane has only one opponent, Andrew), and our goal is to guess where is the phrase that he entered. We would get a point for every correctly selected word. At the same time, Andrew would get a point for every word he wrote that we did not select, as well as for any word from the original sentence that we select by mistake. So we need to choose carefully!
