PRET

Welcome on PRET annotation tool, the first online tool designed to support prerequisite relation annotation on textbooks.

Create a Dataset Annotated with Prerequisite Relations
Thanks to PRET you can upload a corpus (a text) and annotate prerequisite relations between concepts described in the text to create an annotated dataset.

PRET is Collaborative!
Ask your annotators to use PRET and collect as many annotations as you need. Then, you can compare and combine the annotations to obtain a manually labelled text to use as ground truth for your analyses.

Challenge your Annotation
Try different automatic prerequisite identification methods implemented in PRET and compare the results with your ground truth.

Explore the Labelled Text
PRET offers a suite of tools to analyse and compare the annotations and the output of extraction methods. You can also visualise the relations using different visualisation options.

Collaborate with us on the extraction of prerequisite relations!
If you developed a prerequisite extraction method, contact us, we’ll integrate your method and you’ll be able to use the PRET tool to evaluate it against ground truth and other methods, Log In to start using PRET Annotation Tool
