Simon Hengchen
Hi! I am a postdoctoral researcher at Språkbanken Text (University of Gothenburg), where I work within the LanguageChange project. My main research focus is lexical semantic change in multilingual, unstructured, OCRed, historical textual data. I can also do most text mining stuff.
This is a quick overview of my academic outputs, research stays, and teaching. For a full curriculum vitae, please email me at hengchen.simon@gmail.com.
