Pre-Trained Models

The text-package allows you to create pre-trained models using the textTrain() functions. The models can be saved and used on new data using the textPredict() function. The table below shows pre-trained models that are available to download. The models can be called with textPredict() like this:

library(text)

# Example calling a model using the URL
textPredict(
  model_info = "https://github.com/OscarKjell/text_models/raw/main/valence_models/facebook_model.rds",
  texts = "what is the valence of this text?"
)


# Example calling a model having an abbreviation
textPredict(
  model_info = implicit_power_roberta_large_L23_v1,
  texts = "It looks like they have problems collaborating."
)

The textPredict() function 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 table, 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.
