Some Takes from Twitter & Facebook Social data over time The concept of ‘Timeline’ The ‘Social Graph’

SPACE - TIME

Time Things happen over time Online Social Experience: capturing static points

on a continuum – tweets, fb updates These static points are relevant for various

reasons: Importance to self: what I value, what I find fun.. Importance to significant others: 'friends‘Where they happen e.g. I am having fun at

Key Premises

People move from place to place, period (geo-location)

People move for some purpose, and have certain experiences there, and want to share those experiences (social)

What are the chances that my 'motion' influencers are similar to some other (known or unknown) person who could be in the same context? e.g. tourist in the same town? attending a conference?

Creating a New Social Experience A framework that combines social +

location NOT just social…. plus geotagging; but

geo as a central component Three components:

Capture: collect social + location based infoMine: mining that data, finding patterns,

searchVisualize: visualizing this data in a way that

makes sense

Case: GeoLife

A Microsoft Research (MSR Asia) Project Xing Xie, Yu Zheng “… GeoLife focuses on visualization,

organization, fast retrieval, and effective understanding of GPS track logs for both personal and public use. [A] platform for people to effectively manage their GPS data… understand a person’s past experience from GPS data.”

Case: GeoLife

Sharing life experiences with GPS trajectories
