iDOP: Iterated Data-Oriented Parsing as a Model for Diachronic Syntax Maarten Versteegh Abstract: A number of properties of the data-oriented parsing model have also been identified as being important in grammaticalization theories of language change. The exemplar-based nature, the use of probabilities and the incorporation of constructions are shared by both approaches. Building on data-oriented parsing, we present a computational model of syntactic change that can account for the major mechanisms of language change. We show the model's plausibility by simulating several historical situations of change. Keywords:
