This presentation was given at ICWSM 2011. In this presentation, we report on a qualitative investigation into the different factors that make tweets ‘useful’ and ‘not useful’ for a set of common search tasks. The investigation found 16 features that help make a tweet useful, noting that useful tweets often showed 2 or 3 of these features. ‘Not useful’ tweets, however, typically had only one of 17 clear and striking features.
Our results contribute a novel framework for extracting useful information from real-time streams of social-media content
11. Any of it Useful?
Who cares how much data there is!
“I think the challenge not only for twitter, but for
the technology industry at large. Is building
more relevant filters, in real time. Like being
able to surface valuable information
immediately. No matter who it is, whoʼs
listening or whoʼs broadcasting, is a really
really hard problem, and it makes twitter alot
more meaningful[... ]Weʼve gotten really really
good at being able to put content in, into media
[...] getting it out in a relevant, valueable way,
in real time is still very difficult.”
- Jack Dorsey (Creator of Twitter)
