PoTeC: A German Naturalistic Eye-tracking-while-reading Corpus
Deborah N. Jakobi Thomas Kern David R. Reich Patrick Haller Lena A. Jäger
The Potsdam Textbook Corpus (PoTeC) is a naturalistic
eye-tracking-while-reading corpus containing data from 75 participants reading
12 scientific texts. PoTeC is the first naturalistic eye-tracking-while-reading
corpus that contains eye-movements from domain-experts as well as novices in a
within-participant manipulation: It is based on a 2x2x2 fully-crossed factorial
design which includes the participants' level of study and the participants'
discipline of study as between-subject factors and the text domain as a
within-subject factor. The participants' reading comprehension was assessed by
a series of text comprehension questions and their domain knowledge was tested
by text-independent background questions for each of the texts. The materials
are annotated for a variety of linguistic features at different levels. We
envision PoTeC to be used for a wide range of studies including but not limited
to analyses of expert and non-expert reading strategies. The corpus and all the
accompanying data at all stages of the preprocessing pipeline and all code used
to preprocess the data are made available via GitHub:
