GEOTAGGING IS UNCOMMON

GEOLOCATION? NETWORK LOCATION!

• Account information available from Twitter API:– Description (free text)– Location (free text)– Follower network– Twitter join date– Interface language– Interface timezone– Key stats (# followers, followees, tweets, etc.)

• Limitation:– Not available for ‘protected’ accounts (~3.5%)

MAPPING A NATIONAL TWITTERSPHERE

• Account information selected:– Description: mentions of Australian terms, top locations– Location: mentions of Australia, top locations

– Interface timezone: one of eight Australian state timezones

Q&A

BACK TO GEOLOCATION?

NETWORK LOCATION GEOLOCATION?

• Inferring (typical) geolocation:– More local following than intercity/state/country following?

Can we infer your location from that of your followees?– More discussion of local than non-local issues?

Can we infer your location from your typical topics? Can we infer your location from your network’s topics?

• Combining network and geographic location data:– How does information travel across the network?– Does geographic location affect information flows here?

LIMITATIONS

• Twitter API policies:– Pursuit of short-term goals, not long-term strategies– Ill-conceived push to raise revenue through data sales– Counterproductive relationship with research community– Data access shaped to privilege certain limited methods

Most ‘big data’ Twitter research conducted by Twitter, Inc. and commercial research institutes
