Text Models

This repository contains scripts and models compatible with the text R-package. Each model type has its own directory. For adding new model types, please create a corresponding directory, consider adding the model-recipe in the recipes folder, and fill in this README-file.

Tutorial

To use the pretrained models for prediction, follow the following general procedure:

library(text)
textPredict( 
    model_info = "url/to/your/model",
    texts = "texts to predict" 
)

Example

Predict valence using the facebook pretrained model:

predictions <- textPredict(
  model_info = "https://github.com/OscarKjell/text_models/raw/main/valence_models/facebook_model.rds",
  texts = Language_based_assessment_data_8$harmonytexts,
  dim_names = FALSE  # For this particular model, dim_names should be set to FALSE (see Guide, Valence Models).
)

Model Directories

Valence Models

• facebook_model.rds
  • Source: Facebook data from 2442 posts with valence ratings by psychology professionals, based on Preoţiuc-Pietro et al. (2016).
  • Guide: Set dim_names to FALSE.
• facebook_model_reduced.rds
  • Source: Facebook data from 2442 posts with valence ratings by psychology professionals, based on Preoţiuc-Pietro et al. (2016). Principal Component Analysis (PCA) using 20 components has been applied to the embeddings.
  • Guide: Set dim_names to FALSE.
