I've been informed I'm going to organize an ElasticGraph hackathon in a couple of days for a mixed junior/senior frontend/backend dev team of 8 people.
Who's worked on some nifty ElasticGraph projects to kickstart some ideas?
Some ideas:
StackOverflow graph.
Get a dump of the StackOverflow data. Create one doc per question+responses. Index tags and user handles. Explore graph of strongly-related tags and the users who are experts in the area. Provide drill-down into docs to show timelines etc. See https://www.youtube.com/watch?v=1QwmJ_FCMqU&feature=youtu.be
Review fraud
Download Amazon review data. https://snap.stanford.edu/data/web-Amazon.html
Examine relationships between reviewers, product IDs, timeOfPost, language etc
Panama papers
This blog post has some tips and scripts: https://www.elastic.co/blog/using-elastic-graph-and-kibana-to-analyze-panama-papers
Recommendation engine
Take your userID/click data and build a doc per-user which summarises the products they have bought. Then explore "people who bought X also tend to by Y" type connections using Graph. LastFM data is fun to play with: http://mtg.upf.edu/node/1671. Do the same for bad actors too by exploring behaviours of "people who did bad activity X also tended to do activity Y".
Would be interested to hear how you get on
