This repository contains a simple Meteor-powered web application that pulls current trends from the Twitter API and uses AFINN-based sentiment analysis on the tweets (currently US-only to make language processing a little easier) related to the trend to provide a summary of its sentiment and keywords. You can check it out at proles.herokuapp.com, and to actually run it yourself:

curl https://install.meteor.com/ | sh
git clone https://github.com/soycode/proles
cd proles
touch settings.json

You'll then need to put your Twitter API credentials (read-only permission is fine) in the settings.json file as follows:

{
  "twitter": {
    "consumer_key": "your_consumer_key",
    "consumer_secret": "your_consumer_secret",
    "access_token": "your_access_token",
    "access_token_secret": "your_access_token_secret"
  }
}

Finally start it up:

meteor --settings settings.json

Right now it's a pretty simple and minimal "proof of concept", but still interesting in that it gives a quick summary of popular things going on. Some natural expansions I'll hopefully get to pursue (in rough priority order):

• Clean up things, write tests, make sure the code is idiomatic, etc.
• Incorporate other sources of trends (news, other social media)
• Allow for user filtering/searching (instead of getting all trends, search for/view a specific topic and see what people are feeling about that, e.g. "Tech Trends")
• More language processing/cleanup - porting/stemming, stop words, etc. (the sentiment library does tokenize already but more processing may help)
• Incorporate other languages (and possibly translate to English for summary/homogeneity)
• Time: show history (past trends), and possibly show what is trending over larger windows than just "right now" (e.g. like a weekly/monthly/annual "zeitgeist")
• Pull in better/more secondary information (recognize tags/geo data, have inline hide/show info boxes to provide brief summaries, etc.)

But overall, this provides a mostly clean starting point of a pure JavaScript web application. Thanks for checking it out!
