RiTa
Software toolkit for processing English language
From Wikipedia, the free encyclopedia
RiTa is an open-source software toolkit for generative writing and English natural language, originally developed using the Java language by Daniel C. Howe and collaborators, and later implemented in JavaScript as rita.js. Current versions of RiTa (Version 3.0 was released in 2023) are implemented in both Java and JavaScript and integrate with p5.js, Processing, Node and Android.

Features
- Heuristic algorithms for inflection, conjugation, stemming, tokenization, etc.
- Regex lexicon search to match phonemes, POS, meter, soundex and rhyme patterns
- Powerful options for text generation via context-free grammars and Markov chains
- Close integration with the writer-oriented RiScript scripting language (interpreted via Antlr)
- Feature extraction of phonemes, part-of-speech, syllables and stresses
- Letter-to-sound engine for analysis of arbitrary words (with or without a lexicon)
Usage examples
// In JavaScript/Node
let { RiTa } = require('rita');
console.log(RiTa.rhymes('sweet'));
/*[
'beat', 'beet',
'cheat', 'cleat',
'compete', 'complete',
'conceit', 'concrete',
'deceit', 'defeat', ...
]*/
let features = RiTa.analyze('The elephant took a bite!');
console.log(features);
/*{
phones: 'dh-ah eh-l-ah-f-ah-n-t t-uh-k ey b-ay-t !',
stresses: '0 1/0/0 1 1 1 !',
syllables: 'dh-ah eh/l-ah/f-ah-n-t t-uh-k ey b-ay-t !',
pos: 'dt nn vbd dt nn !',
tokens: 'The elephant took a bite !'
}*/
// In Java/Processing
import rita.*;
void setup()
{
size(100, 200);
textSize(16);
fill(0);
String[] words = RiTa.rhymes("sweet");
for (int i = 0; i < words.length; i++) {
text(words[i], 20, 20 + i * 18);
}
println(RiTa.analyze("The elephant took a bite!"));
}
