sentopics 1.0.0

Breaking changes

• Renamed base class sentopicmodel to sentopicsmodel for consistency with the package name.

• Renamed various functions and classes to snake_case style.

  • renamed function mergeTopics() to merge_topics()
  • renamed function topWords() to top_words()
  • renamed function plot_topWords() to plot_top_words()
  • renamed function chainsScores() to chains_scores()
  • renamed function chainsDistances() to chains_distances()
  • renamed S3 class topWords to top_words
  • renamed S3 class multiChains to multi_chains

• Corrected naming of Reverse Joint Sentiment/Topic model (rJST). To align with this change, internal attributes of sentopicsmodel objects have been renamed from reversed to reverse.

• Modified names of columns in the PicaultRenault_data dataset to syntactically valid names.

• Removed .sentiment docvars in ECB_press_conferences dataset.

• Fixed a bias in JST and rJST models caused by cached probabilities.

• Fixed a labeling error when extracting sentiment time series for rJST models.

Other changes

• Reformatted codebase using Air.
• Removed a comprehensive assessment from the PicaultRenault_data dataset not present in the original paper.
• Fixed model relabelling with stored scaled sentiment, optional arguments in sentiment_series(), melt() dispatch with current data.table versions, and JST coherence dimension labels.
• Restored R-backed token and assignment indices after sampling errors, and record unevaluated log-likelihoods as NA when computeLikelihood = FALSE.
• LDA inference performance improvements.
• Miscellaneous test improvements.
