lexicon.inverter.js

// target was https://github.com/dariusk/spewer/blob/master/lib/lexicon.js

var rewriter = function() {

  var oldLex = require('./lexicon.old.js');

  var tagbag = {};


  for (var word in oldLex) {

    var tags = oldLex[word];

    for (var i = 0; i < tags.length; i++) {
      var tag = tags[i];
      // hoo-hah! the tag can be further split as "VBN|VBP"
      var subtags = tag.split('|');
      for (var j = 0; j < subtags.length; j++) {
        var stag = subtags[j];
        if (!tagbag[stag]) { tagbag[stag] = []; }
        tagbag[stag].push(word);
      }
    }

  }

  for (tag in tagbag) {
    tagbag[tag] = tagbag[tag].sort();
  }

  require('fs').writeFile('lexicon.txt', JSON.stringify(tagbag, null, 2));
