pos2tracery

npm version

pos2tracery is a tool stemming from my NaNoGenMo 2017 Artbook Project and modified with behaviors from the NaNoGenMo 2018 Wink Project it uses the Wink POS Tagger which uses the transformation based learning (TBL) approach to create tracery grammars to take sentence forms from a corpus, but replace the parts of speech within them with other parts of speech from throughout the corpus. It is aware of contractions and punction; and creates tracery's default english modifiers.

MODULE USAGE

pos2tracery can also be used inside of your node projects. Each option is set by using the long-form version of the CLI option The only change is that since delete is a reserved word in Javascript the function is called del

const p2t = require('pos2tracery');

let merged = p2t.merge({
  inputA: p2t.del({
            input: "./grammar_A.json",
            toss: "story"
          }),
  inputB: p2t.del({
            input: "./grammar_B.json",
            keep: "story"
          })
  });

  p2t.generate({
    input: merged,
    modifiers: true
  });
