tagspewer v0.3.1

tagspewer

Spew text based on pos-tagged-templates and associated lexicon; includes tools for parsing text and generating templates and lexicon.

Inspired by Darius Kazemi's spewer. It also includes a default lexicon that is a slightly edited version of Kazemi's, primarily modified to be tag-based.

usage

var Tagspewer = require('tagspewer').tagspewer;
var tagspewer = new Tagspewer();
var cleaner = require('tagspewer').cleaner;
var tagbagify = require('tagspewer').tagbagify;
var templatify = require('tagspewer').templatify;

var template = 'DT NN IN DT NN VBD DT NN IN NN , VBN TO DT JJ NN .';

console.log(tagspewer.spew(template));
// 'such bullhide post all revaluing collided thees velours foh deadwood , teed gotta either zilch areosol .'

var lexicon = { 'JJ': ['big'], 'NNS': ['bicycles'] };
console.log(tagspewer.spew({ template: 'This is a JJ pile of NNS .', clean: true, lexicon: lexicon});
// This is a big pile of bicycles.

See below for sample lexicon.

Call tagspewer.spew(tags), where tags is a space-delimited string of keywords. A default lexicon is provided with part of speech tags, as defined below. This will return a string of matching words.

generate lexicon and template files

The process.js file is found inside of \lib.

• process -j -i d:\temp\purple.cloud.txt -o purple.json
• process -t -i d:\temp\purple.cloud.txt -o purple.tmpl

take this source file (source.txt):

# found @ http://www.wussu.com/poems/agh.htm
I'm with you in Rockland
         in my dreams you walk dripping from a sea-journey on the highway across America in tears to the door of my cottage in the Western night

process -t -i source.txt -o sample.tmpl

yeilds:

# found @ http://www.wussu.com/poems/agh.htm
NN VBP IN PRP IN NN:::I am with you in Rockland
IN PRP$ NNS PRP VB VBG IN DT NN IN DT NN IN NNP IN NNS TO DT NN IN PRP$ NN IN DT JJ NN:::in my dreams you walk dripping from a sea-journey on the highway across America in tears to the door of my cottage in the Western night

I'm was expanded to I am to improve legibility (see notes, below, on expansion) The original text is appended to the template for reference only. The template and the original text are separated by 3 colons :::

TODO: make this into a JSON array, with template and original text as separate keys

Likewise, process -j -i source.txt -o sample.json yeilds:

{
  "NN": [
    "I", "Rockland", "cottage", "door", "highway", "night", "sea-journey"
  ],
  "VBP": [
    "am"
  ],
  "IN": [
    "across", "from", "in", "in", "in", "in", "of", "on", "with"
  ],
  "PRP": [
    "you", "you"
  ],
  "PRP$": [
    "my", "my"
  ],
  "NNS": [
    "dreams", "tears"
  ],
  "VB": [
    "walk"
  ],
  "VBG": [
    "dripping"
  ],
  "DT": [
    "a", "the", "the", "the"
  ],
  "NNP": [
    "America"
  ],
  "TO": [
    "to"
  ],
  "JJ": [
    "Western"
  ]
}

index -t sample.tmpl -p sample.json -o sample.txt yeilds a sample.txt:

Due to the small size of the original, there is a lot of mirroring in this output. With a larger lexicon, you are unlikely to see that.
