Overview
FilterBubblet is:
- a JavaScript bookmarklet that sends Google search results for a term to a web service
- a web service that stores the results in a database
The idea was born of the TED Talk "Filter Bubble" and Jeff's earlier experiment to test the filter bubble theory manually.
Rationale
- determine if the 'filter bubble' exists, and
- analyze the data and make useful observations, like showing people results they didn't see
- open the filter bubble experiment we conducted on the mailing list to a much larger userbase
- potentially thousands of people could install the filterbubblet bookmarklet and send their results
Open Questions
- Is it possible to reliably extract Google search results from the result HTML?
- Yes, or so it appears. The list of links is always in an ordered list with an element ID of "rso". Individual links appear to all be of class "tl". Drew 12:40, 8 June 2011 (MDT)
- Even easier than that. The <a> is always of class "l" so the following code will dump, in order, the list of google search results (assumes use of Firebug plugin for Firefox).
javascript:
var p=document.getElementsByTagName('*');
var j=1;
function gc()
{
for(i=0;i<p.length;i++){
if(p[i].className=='l'){
console.log(p[i].href);
}
};
};
gc();
Random Ideas
- Geographic coordination
- Web service could use GeoIP to guess user location, associate results with that location
Technical References
- jQuery Bookmarklet Generator
- How to Create a jQuery Bookmarklet
- Numbering Google Search Results with JavaScript bookmark - difficult to read, but bookmarklet does something close to what we want
- Same origin policy Workarounds - we'll need to use one of these techniques to send results to the database
- Using Sinatra with Bundler to Deploy on Heroku - possible web service/database starting point (Heroku is free, and Sinatra is comparitively easy)
