5. Social Networking & Content Delivery
Various work has studied how the social relationships can be used to distribute content in a privacy preserving and cost-efficient manner. i.e. - Friends share common locations more often - Friends tend to have similar interests. We capture this information in the “Mobile Assignment”- Survey sheet.

6. Assignment - Part 1 & Part 2
Data Pre-Processing & Visualization
- Apply a clustering algorithm on the dummy data to extract points of interests.
Extract the number of users in the experiment using the data
files
- For each user plot a scatter plot of Wi-Fi network connected against the time of day
Similarity Matrices
- For each user pair in the dataset calculate the similarity measures
Spatial Co-Location Rate, Spatial Cosine (ref: Hand Out)
30 marks

7. Assignment - Part 3 Data Analysis
- Study the differences in the similarity measurements between friends and non-friends. Does friends have similar mobility patterns?
- Prepare brief report on the results
60 marks
Can you think of other similarity measures which can be used for this analysis?
