Vocabulary

Most humans and therefore most documents and websites have limited vocabularies, usually around 20,000 words and no more than 35,000 words and rarely more than 50,000 words. Vocabularies are typically much smaller than the documents they represent. A Vocabulary() is simply a hash table of all the words you've given it and how many times it's seen the same word. In this way, every word is ranked by the frequency and size of the word. Like any json object, you can store a vocabulary anyway you like. Given their small size, I cache them locally in window.localStorage and can store them permanently in a NoSql db if desired. You really only need to store a user's vocabulary as they click around your site, return, etc. A page's vocabulary should be created dynamically by the client and independently of the CMS, etc.

Vocabulary() can run on the server (Node) or the client (Javascript). It does not depend on jQuery or any other libraries, but is compatible of course.

Usage

It's just a tiny amount of javascript, so you can include it in the browser.

<html>
<head>...</head>
<body>
...
<script src="Vocabulary.js"></script>
</body>
</html>

or on the server

const Vocabulary = require('Vocabulary.js');

User Stories

As a user, I want to be "heard" and "known" as I click around your site(s), so that when your sight suggests other products, stories or opportunities they will be relevant to me and my demonstrated interests.

let userVocabulary = new Vocabulary();
userVocabulary.add("all the words on the page");
button.click(() => userVocabulary.add("some words associated with this button"));

As a programmer, I want to maintain a user's vocabulary and then present the user with relevant options in the dynamic components on the site.

let preferences = usersVocabulary.order("shoes hats underwear");
switch(preferences[0]) {
  case "shoes":
    displayShoes();
    break;
  case "hats":
    displayHats();
    break;
  case "underwear":
    displayUnderwear();
    break;
}

Class Definition

class Vocabulary {
    constructor(text){} // add initial words to my vocabulary
    add(text){} // add more words to my vocabulary, parse, etc.
    addString(word, count){} // add one word or phrase without parsing
    // count defaults to 1, unless you want to "seed" a word with a high count
    addVocabulary(that){} // combine two vocabularies
    rank(word){} // calculate the rank of a word being used in the vocabulary
    order(words){} // given a list of words, sort them in order of rank 
    relevance(that){} // calculate how relevant "that" vocabulary is to me
}
