Starting COSMOS and overview

Once you finished your installation, this video will give you an overview of COSMOS including its tools and functionality.

Signing into Twitter

As one of the rare applications, Twitter data can be collected in real time via desktop applications. In order to do so, a twitter connection need to be established using your twitter username and password.

One percent sample collection

A basic but powerful example is to collect a one percent sample. Over 24 hours, COSMOS would collect 500 million tweets, thus only practical over a specific period of time. Also comes in handy if you want to test if your twitter authorisation is working, 

Filter collection

Apart from the one percent sample you are able to refine your twitter stream by applying filters. These may include message filtering (keywords and hashtags) or user filtering (twitter accounts).

Table view intro

To examine the sets of tweets we collected we use what is called "the table view". Beginning with the time stamp, the table view will give you an overview of different metrics that are collected alongside with tweets.

Importing twitter data

If you want to analyse data retrospectively you can do so by importing twitter data. Particularly for this week's tutorial we will need it to start of our analysis of "TV Debates".
If you replicated all videos above, you are now able to apply those tasks in a real world example - A TV debate (see next section).
