The Language-Based Assessment Model (L-BAM) Library

The L-BAM library comprises information about pre-trained models. The models can be called with textPredict(), textAssess() or textClassify() like this:

library(text)

# Example calling a model using the URL
textPredict(
  model_info = "facebook_valence",
  texts = "what is the valence of this text?"
)


# Example calling a model having an abbreviation
textClassify(
  model_info = "implicit_power_fine_tuned_roberta",
  texts = "It looks like they have problems collaborating."
)

The text prediction functions can be given a model and a text, and automatically transform the text to word embeddings and produce estimated scores or probabilities.

If you want to add a pre-trained model to the L-BAM library, please fill out the details in this Google sheet and email us (oscar [ d_o t] kjell [a _ t] psy [DOT] lu [d_o_t]se) so that we can update the table online.

Note that you can adjust the width of the columns when scrolling the table.
