CREST: Corpus of Recommendation Strength

CREST is a collection of clinical guidelines annotated with instances of recommendations, each labeled with their strength of importance as specified by their authors. As data is drawn from many disparate authors, a unified scheme for labelling importance is defined, together with a mapping for each guideline.

For a detailed description of the corpus, please see the paper by Read, Velldal, Cavazza & Georg presented at LREC 2016, A Corpus of Clinical Practice Guidelines Annotated with the Importance of Recommendations:
