Naive Tweets is an app that classifies tweets by language using a naive Bayes classifier. It is written in Node.js.
Tweets are pulled from the twitter streaming api and classified on the fly.
A live example is hosted at http://naive-tweets.bn.ee/.
Provided is a script to pull tweets from list of specified locations and auto-classify by assumed languaged. For instance, tweets from Surakarta, Indonesia are all autoclassified as Indonesian. This provides a large amount of training data which allows the classifier to predict the language of a stream of incoming tweets.
To run the training script
npm run-script train
Locations and languages are specified in lib/languages.js.
This process takes a while, as tweets from specific regions are collected, and limited to one tweet per user (to avoid basing the classification around a small number of users.
A front-end to view a stream of live tweets and their predicted languages is provided.
node index.js
It provides views of each language's tweets that have been collected.
In order to access the Twitter streaming API you'll need to have an API key. You need to get these keys from the Twitter Developers Page.
Make a file called options.js that looks like the following:
module.exports = {
consumer_key: <KEY>
, consumer_secret: <SECRET>
, access_token_key: <SECRET>
, access_token_secret: <SECRET>
, mongo_node_database: 'tweets'
, mongo_node_host: 'localhost'
}
