Abstract

While most dialectological research so far focuses on phonetic and lexical phenomena, we use recent fieldwork in the domain of dialect syntax to guide the development of multidialectal natural language processing tools. In particular, we develop a set of rules that transform Standard German sentence structures into syntactically valid Swiss German sentence structures. These rules are sensitive to the dialect area, so that the dialects of more than 300 towns are covered. We evaluate the transformation rules on a Standard German treebank and obtain accuracy figures of 85% and above for most rules. We analyze the most frequent errors and discuss the benefit of these transformations for various natural language processing tasks.
