What is Data Mining?

• Inform actionable business decisions •Contrasts with “machine learning”

16 © 2012 SolidQ

Media Case Study

•Millions of posts per year (different moderation scenarios) •About 25% are human moderated •About 10% of the moderated posts fail •No Business Intelligence applications for analysis

or reporting

Moderation, Data Mining

• Contextual Information • Time • Location • User

• At 10am comments are safer than at 2AM. • A user maybe safe talking about science bad

dangerous talking about sports. • If a thread is hot (dangerous), comment maybe hot. • Combining context pattern the systems assign risk to

posts without going into the text.

Solution – Logical Model

•Post Context (behavior analysis) • Patterns, data mining.

•Post Content (text analysis) • Profanity, low score sentences, text mining, mood or

tone (sentiment analysis)

Typically Available Data on Posts

•Historical and real time data for: • User (e.g. userid, email, nationalid) • Location (e.g. Life & Style Fashion) • Time (e.g. 12 March 2011 18:56) • Content (e.g. text, link, picture, video). • Moderation result

•Other attributes like geography, age, education could be used

Post context, Patterns, Data Mining •User behavior. • Time behavior. • Location behavior.

Conclusion: Benefits

•Moderating half of the total posts, the solution captures 90% of failing posts. The remaining 10% seem to be likely safe posts. •Using Intelligent Moderation, media companies

scan the whole universe of posts at a comparatively low cost. •At peak times, Intelligent Moderation works

perfect.
