Interactive Dashboard
Visit the webpage with an interactive dashboard to explore, filter, and download the +5K copy task corpus.




We are happy to make a multilingual corpus available (open access) that currently consists of more than 5000 copy tasks. 

  • The + 5K corpus is carefully cleaned and fully anonymized.
  • The Shiny interface allows users to filter the corpus based on about 10 variables.
  • The selection can be downloaded in different formats and levels of aggregation (from raw idfx to synthesized analysis).
  • The selection can be explored using different interactive graph visualizations.
  • Researchers can upload their own corpus (or single copy task file) and compare it to the (selected) corpus.
  • An extra webpage is designed for laypersons wanting to take a copy task to test their typing skills. They get dashboard feedback in a user-friendly and attractive way and can compare their performance with (age-related) participants in the corpus. (Specially designed to further expand the corpus).
