Semantic Sabotage

Introduction

Semantic Sabotage is an open source platform for creating live typographic YouTube transforms.

Each transform uses HTML5 and Javascript to visualize the transcript of a YouTube movie, as it plays. The transcripts are analyzed with the LIWC dictionaries, created by James Pennebaker and the UT Austin Department of Psychology.

Semantic Sabotage was designed and coded by Sosolimited.

Dependencies

  • Apache
  • PHP 5

You can install Apache and PHP manually on OSX or Linux, or download a one-click bundle: MAMP (for OSX) or WAMP (for Windows).

Installation

  • Fork and clone the repo.

  • Enable Apache and PHP (instructions linked above).

  • See Eyeo-Architecture.pdf for more about software layout.

Get the Source Code

Assuming you've followed the Apache and PHP setup instructions above, you're ready to get the source code. We recommend that you sign up for GitHub account if you don’t have one. If you don’t want to sign up for one, there are instructions below for getting the code.

With a GitHub account

  1. Log into your account and go to the URL https://github.com/sosolimited/semantic_sabotage
  2. Press the Fork button at the top right, which will fork the repo to your account.
  3. On a Mac, use Terminal and on Windows, use cmd, and
    Navigate to the folder where apache is set up.
    If you used MAMP on a Mac to set up apache, the folder is Applications/MAMP/htdocs
    If you set up Apache manually on a Mac, the folder is ~/Sites
    If you used WAMP on Windows to set up apache, the folder is C:/WAMP/www
  4. Type in
    git clone [email protected]:your_name/semantic_sabotage.git
    where your_name is your GitHub account name, and press return.
    This will create a folder in your current folder called semantic_sabotage
  5. Navigate into this folder.
  6. Open this folder in Sublime or your chosen text editor.

Without a GitHub account

  1. Go to the URL https://github.com/sosolimited/semantic_sabotage
  2. Press the Zip button with the down arrow to download the code.
  3. Save it into the folder where Apache is set up. See step 3 above for where this is on different machines.
  4. Navigate to the folder where you saved the zip files and unzip it.
  5. It should be in a folder called semantic_sabotage_master
  6. Open this folder in Sublime or your chosen text editor.

Creating your own transform

You can start with a template, with an existing transform, or from scratch. We’re going to do a quick walkthrough of the steps to create your own.

  1. Once you have chosen a transform from sabotage.sosolimited.com to start with, navigate to the fills directory.
  2. Copy and rename the .js file as well as it’s corresponding .css file.
    For example: if you were starting with the left scroll template,
    Copy and rename fills/template_leftScroll.js into the fills directory.
    Then copy and rename fills/css/template_leftScroll.css into the fills/css directory.
    The js and css files must have the same exact name.
    For the following instructions, let’s assume you named them my_transform.js and my_transform.css
  3. Open your new js file and change the following two things
-At the very top, there is a line that looks like  
```var mode = function(id) {```  
Change it to be the name of your js file. For example,  
```var my_transform = function(id) {```  

-Near at the top, give your transform a name. This is how it will appear in the menu list. For example, change 
```name: "Left Scroll",```  
to   
```name: “My Sweet Transform”,```
  1. Open your new css file and change the selectors to match the name of your file
    e.g. if you started with template_leftScroll and renamed it my_transform, you would change all instances of #template_leftScroll in the css file to #my_transform.
    We are using this convention to avoid collisions with CSS names.
  2. If you started with a template, you should comment out the line at the top of the js file
    template: true,
  3. Reload the page in your browser and you should see your new transform in the list.

The main functions you’ll be working with in the transform are
init : Called once after the transform is created. Build things you will re-use here. enter : Called once each time the transform is shown. Reset your transform and clean things up in here. handleWord : Called each time a new word is ready. handleSentenceEnd : Called each time a sentence is completed. handleStats : Called every time a line of captions is completed. Passes in interesting linguistic information. appendWordInContext : Called by handleWord to append element to DOM.

Some useful notes:

  • Each transform has a high-level container div. Always refer to this with this.el as in this.el.append(<div id=”myDiv”></div>);
  • To change the URL that your transform uses, set the defaultURL var defaultURL: "http://www.youtube.com/watch?v=u02nZW0QiSE",
  • To make your movie start at a specific time, add a &t=0m3s argument to your URL defaultURL: "http://www.youtube.com/watch?v=u02nZW0QiSE&t=0m5s",
  • See the Message Specs section of the WIKI for detailed information on the messages.

LIWC Dictionary

The LIWC Dictionary is loaded All words are looked up against the LIWC Dictionary.

  • LIWC categories and abreviations can be found here.
  • getCategoryIndex(category) -- returns the index of the category (useful for comparing proximity of word cats ~ relatedness), returns -1 if not found
  • getCategoryFullName(category) -- returns full name of category, returns abbreviated name if not found

YouTube Captioning

YouTube search terms can be modified with ', cc' to isolate results to content with closed captioning. Many videos have automatic captions, which are better than nothing, but are often inaccurate and contain little to no punctuation. For this reason, Semantic Sabotage first checks for official captioning, but will default to automatic captions when official captions aren't available.
