IDAT209 – Tweetflu

Eventually I decided to use processing for the core of the software as it is more easily able to read XML and access mySQL databases.

For the map itself we used the Google maps API which provided all the features we needed. To get the data into the page, we used PHP to access the database and cycle through each row adding the code for displaying an icon at the infected account’s last know location.

IDAT209 – Tweetflu 2, The Retweeting

The data collection portion of this project will be written in Java because we have some experience with it and it’s more appropriate then other languages we know.

I’ve started with a small experiment using php to get the location of a tweet then list the users near it at the time which appears to work fairly well, it is now a case of porting and expanding this.

The application will have to be able to read JSON and manipulate a mySQL/SQLite database.

IDAT209 – Tweetflu

For this project we came up with the idea of using geolocated tweets in twitter to create a game on a huge scale. At the start a single user will be recorded in a database as ‘infected’. Their geotagged tweets provide a time and place which is then queried using Twitter’s search API for more people who were in the near at the time. These people also become ‘infected’ and the process is repeated for everyone in the database at regular intervals. The information stored in the database will allow us to visualise the spread of the ‘virus’. We predict that the spread will be exponential and with enough time and resources would reach most of the people that use geotagging. The game is based on Virus which is in turn based on hit/tag.

There are two halves to the project, the first is the data collection and the second is visualisation of this data. The biggest problem is the limitation on the number of queries to the twitter APIs a single client can make within an hour before being blocked and the potential for the number of accounts overwhelming the system.
