The text-package allows you to create pre-trained models using the
text-train functions (e.g., textTrain()) or the fine tune
functions (e.g., textFineTuneDomain). The models can be
saved and used on new data using the text prediction functions (e.g.,
textPredict()). The L-BAM library below shows pre-trained
models that are available to download. The models can be called with
textPredict(), textAssess() or
textClassify() 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
textClassify(
model_info = "implicit_power_roberta_large_L23_v1",
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.
