RiTa from old norse: 'to write, sketch, or scratch'       

natural language processing for generative literature

 
  • Support for probabilistic context-free grammars (CFGs)
  • Support for generation via Markov (N-Gram) models
  • Support for KeyWord-In-Context search (see RiKWICker)
  • Integration with WordNet (here), and JSAPI for text-to-speech
  • Feature Extraction: Syllables, Phonemes, Stress, Pos, etc.
  • Constraint-based word substitution (see RiSubstitute)
  • Support for user-customizable lexicons (RiLexicon)
  • Web/Text-Mining Capabilities (see RiHtmlParser)
  • Audio support for RiText objects (see RiSample)
  • Pluggable 'behavior' model for events/animations etc.
