The use of linguistic and world knowledge in language processing

Abstract

AbstractThere has been considerable investigation of the roles that linguistic and world knowledge play during language comprehension. This investigation is important because its results have ramifications for both basic questions about how the mature intact language comprehension system functions and for applied questions regarding how comprehension systems that are impaired by aphasia might function. In the current paper, we review debates and research related to the representation and use of linguistic and world knowledge in language comprehension and then describe a recent computational model that takes both world and linguistic knowledge into account in predicting language comprehension difficulty. We then review empirical work that attempts to characterize the interactions and potential trade‐offs between world and linguistic knowledge during language comprehension, and relate this work to the computational model previously described. We conclude with a brief overview of a few open questions regarding the representation of linguistic and world knowledge.
