Gregor Kappler
Gregor Kappler carries out psychometric research and data science consulting, and is founder of FilingForest, a julia-focused startup developing solutions for fast unbiased measurement in graph data.
Gregor was initially trained as a mathematician and psychologist, has implemented solutions for semantic text analytics for his PhD in 2007, and developed psychometric models for measuring with texts.
He has worked as a lecturer and researcher at the University of Vienna and the University of Jena and worked on a series of predictive analytic projects for software vendors and customers.
Gregor has switched to Julia from R in 2018, and is creator of the IterableParsers package which provides parser combinators for fast, recursive and type-save parsing in pure Julia.
Sessions
I will introduce the CombinedParsers package for writing complex recursive parsers efficiently in a composable functional style.
The package API will be demonstrated by example of an CombinedParser for regular expressions which generates compiled regular expression parsers in pure julia.
Far more expressive than regular expressions, parser combinators allow for arbitrary transformations and higher-order parsers depending on the parsing state (exemplified with a very short html parser).
