gowalla-exp

The trajectory based analysis and experiment on gowalla dataset.

Background

This Gowalla-centered experiment is one example of using geographical data to infer the social strength between users. One beauty of this dataset is that it provides the on-line social networks which can serve as a ground truth of the friendship relation.

File Structure

My simulation codes follow my personal consistent style.

• src -- all java simulation program
• matlab -- all matlab plotting scripts
• python -- all intermediate date process scritps
• sqlscirpts -- (deprecated) at the beginning of the simulator coding, I plan to use the MySQL database. But later I abandon this idea.
• img -- (deprecated) some png image generated by Java
• all the other folds and txt files contain intermediate simulation results

Project Wiki

Now this project has a wiki page. It explains the functionality of each components, and gives a walkthrough to replicate the experiment results.
