text2map 0.1.6.9001

Working on an encoding error in fastmatch which shows inconsistent behavior with non-ASCII characters. This dev version provides a temporary fix.

text2map 0.1.6 (2022-08-17)

Improvements

• Add functionality
  • doc_centrality calculates four graph-based centrality metrics using DTMs
  • doc_similarty calculates four document similarity measures using DTMs

text2map 0.1.5 (2022-05-23)

Improvements

• Replaced dependency
  • using ClusterR for get_regions, instead of mlpack
  • Uses the Armadillo library k-means algorithm only (no longer provides an option)

  • seq_builder creates a token-integer sequence representation
• Added Shakespeare metadata for examples
• Import Matrix package methods

text2map 0.1.4 (2022-04-12)

Improvements

• Added functionality
  • dtm_builder includes an option to return a dense base R matrix
