1. UC CEISMIC: Some thoughts on crowd-sourcing earthquake content Dr. Christopher Thomson UC CEISMIC Canterbury Earthquakes Digital Archive www.ceismic.org.nz @UCCEISMIC

7. Benefits and Challenges Benefits: -Gather content from a variety of people otherwise hard to engage with -Enable people outside the project to encourage contributions, eg teachers, community leaders. Challenges: -Earthquakes are always potentially sensitive or frustrating topic -Difficult to sustain a relatively 'open' call for people's digital content – a tightly defined task / proposal is usually better for crowdsourcing.

11. What other crowdsourcing would CEISMIC do? 1.HITLab NZ want to integrate content gathered through the CityViewAR mobile app into CEISMIC. 2.Tagging/annotation in phase 2 development -Multiple layers of tags or annotations: curated, crowdsourced, machine generated -Could encourage people to give more content and engage with the rebuild and longer term issues -Issues: distinguishing between tags from different origins, likely to need moderation/user management.
