Package: certainty-estimator
certainty-estimatorIntrocertainty-estimator is a package used to estimate the certainty of scientfic findings. It is released with

which takes a single text or a list of texts, and returns a list of raw values in[1,6](higher means more certain, while lower means less).# Predict certainty for a single scientific finding
