    <abstract>In the framework of distributional semantics, we introduce a novel notion and operationalisation of semantic information for natural language. The key idea is as follows: a linguistic sign carries semantic information about a document if it reduces the amount of surprisal for a language processor. We consider two systems, an informed one and an uninformed one, and describe semantic information in their terms. Processing effort is quantified via surprisal where the informed system is ‘aware’ of the linguistic sign and the uninformed one is not. On an English fairy tale corpus and on two German news corpora, we tested successfully the prediction that if the linguistic sign in question carries pre-information through semantic surprisal, the current level of surprisal for the language processor is reduced. The conclusion is that the degree of semantic information results from the degree of semantic prior information.</abstract>
