Twitter: Some Facts and Figures

•  Launched in 2006 •  Approximately 550 million active users

worldwide •  About 200 million monthly active users •  An average of 400 million tweets are sent

everyday globally •  60% of the monthly active users log on using

a mobile device at least once every month

Twitter and the Tweeps

•  Twitter…can be more of a news media than even a social network (Kwak et al, 2010)

•  Breaking news and coverage of real-time events are all shared under the 140-character limit

•  Twitter users search for up-to-the-second information and updates on unfolding events

Twitter for Crowdsourcing. That Is…

Collecting information from the “crowd” •  Allows for a wide reach of people in inexpensive ways •  Large amounts of data can be obtained quickly, and often in real time •  Not necessarily through tech, but nowadays most use tech such as online or via mobile phone • Crowdsourcing fosters citizen engagement with the information—to dispute, confirm, or acknowledge its existence.

Mapping Kenyan Election Events, Thanks to crowdsourcing!

What is there to (Twitter) crowdsourcing?

Viability: In what situation/events is crowdsourcing a viable venture likely to offer worthwhile results/outcomes? Validity: Does crowd-sourced information offer a true reflection of the reality on the ground? Verification: Is there a way in which we can verify that the information provided through crowdsourcing is indeed valid? If so, can the verification process be automated?

Crowdsourcing during an Election •  What, if any, particular conditions should be in place

for crowdsourcing of information to be viable during an election period?

•  Can crowd-sourced information be validated during

an election period? If so, what is the practical implementation of doing so?

•  How do different crowdsourcing methods contribute

to the quality of information collected?

Page 9: 3Vs Crowdsourcing presentation *iHub_Research

Why Elections? o  Elections in Kenya have been noted to spark many

online conversations, especially with the continued uptake of social media;

o  Citizens have an important role to play to contribute

information from the ground; o  Existing election crowdsourcing initiatives (such as

Uchaguzi), but none use passive crowdsourcing; o  Research exists around crowdsourcing during

disasters, but does not yet exist around elections.

Why Crowdsourcing, Kenyan Elections and #KoT

•  #KoT have participated in crowdsourcing activities severally, under hashtags such as #CarPoolKE, #findfuel, #SomeoneTellCNN etc.

•  Approximately 90,000 tweets generated during the first Kenyan Presidential Debates (as monitored using popular hashtags)

•  Election-campaigning was also digital

Page 11: 3Vs Crowdsourcing presentation *iHub_Research

(Online) Passive Crowdsourcing vs. Active Crowdsourcing

• Active – Open call made for participation (e.g. Ushahidi’s Crowdmap).

• Passive – Sifting through content already being generated (e.g. on Twitter/Facebook) to capture relevant information.

What we did

Cross-comparison of different media sources: o  Traditional Media o  Data mining from Twitter o  Uchaguzi Crowdsourcing o  Fieldwork

From the Westgate Incident… Mining tweets from the Westgate attack manually has been labour-intensive, limiting us to sufficiently analysing the first half hour (12:38 PM – 1:18 PM GMT+ 3) Further analysis into Twitter data from the incident will require machine learning techniques.

Page 22: 3Vs Crowdsourcing presentation *iHub_Research

In Summary: o  Kenyan social media content is rich with real-time

updates of happenings that might not be present in mainstream media reports.

o  Mining of crowd-sourced data appears to be high value

when one is looking for timely, local information. o  There are indeed considerations that are useful for

assessing and running an election-based crowdsourcing activity.

Next Steps

•  Testing the 3V’s Framework on other election-related crowdsourcing opportunities

•  Move to real-time analysis of tweets •  Provide tools for verifying crowdsourced

information. •  Integrate research to media practices •  Working with local media organizations to build a

useable tool for collecting real-time newsworthy incidents from the crowd
