could add together the directions given by two clues to create a new clue that gets you even closer to the treasure. This is similar to what the researchers are trying to achieve with "deductive additivity". 

In this analogy, each clue is like a sentence, and the direction it points you in is like the sentence's embedding (its representation in mathematical space). The treasure is like the logical conclusion of several sentences. 

The researchers are trying to find a way to represent sentences as directio
