Modelling and Measuring Information Density

Project B4

Classical language models predict a word given a sequence of predecessor words. We will extend this to condition on knowledge from the environment that is to condition not only on the linguistics context but also one context from the real world. In one branch of the project, we will consider language models that also condition on an image.

Knowledge of the image in whose context the text was produced should help to predict the next word. In a second branch of the project we will consider, knowledge bases, question-answer data sets and states of a game as additional context. The surprisal and the predictability of an utterance like “Pawn from E2 to E4” depends on the present state of a chess game.
