SFB 1252 Prominence in Language - C3 Reference management in bilingual narratives
Description: Prominence is a key notion in our understanding of language as a flexible system. It plays a major role in building linguistic structures and in organizing the communicated information into coherent and continually updated discourse representations. The overall goal of the CRC Prominence in Language is to shed light on the nature of linguistic prominence.
