Analytics: Online Controlled Experiments – Listening to the Customers, Not to the HiPPO

by on Apr.09, 2010, under Meeting Notes

Ronny Kohavi (Microsoft) started out by telling a famous true story about Greg Linden’s experience moving a recommender to the shopping cart at Amazon.  A Senior VP of Marketing vetoed Greg’s proposal fearing that it would distract customers from checking out and paying for the items already in their shopping basket reducing conversion.  This is where the “HiPPO” in the title of Ronny’s presentation comes from.  It stands for the “Highest Paid Person’s Opinion” and sometimes for the person (e.g., the VP) holding the opinion.  The Amazon story had a happy ending because Jeff Bezos had established a corporate culture that allowed for experiments to be run so Greg was able to run an experiment to test the hypothesis of the HiPPO.  It turned out that conversions did indeed drop but the increased revenue due to customers purchasing recommended items was substantially greater than the loss.

Analytics: Research in Analytics for Operational Impact at HP

by on Apr.09, 2010, under Meeting Notes

Jaap Suermondt (HP Labs) talked about how his lab uses analytics to support operations at HP. Jaap started with an example of procurement of disk drives.  HP ships two PCs per second and buys more disk drives than anyone else so they have to have accurate estimates of demand. This is roughly equivalent to predicting how the economy and stock market will do. But by combining genetic algorithms and economic and statistical models, HP was able to predict that the economy would improve and demand would improve by five percentage points more than others predicted. This was the subject of a Business Week article and video in 2009 that talked about how earlier genetic algorithms work was revived and applied to this problem.

Analytics: An Applied Researcher’s Perspective

by on Apr.09, 2010, under Meeting Notes

Jeffrey Kreulen emphasized the question “What is the business problem that you have to solve?” and noted that IBM likes to hire “T-shaped people,” with breadth and depth and also with experience in business as well as technology. Kreulen showed several interesting examples of the work of his group at IBM’s Almaden Research Center. One example involved corporate brand and reputation analysis implemented in a system called COBRA. The system is used by IBM’s global professional services group and parts of it will be included in Cognos. The system uses sentiment analysis and taxonomies and text analytics plus influence analysis to listen to how people are talking about brands.

New Uses for WordNet

by on Jan.13, 2010, under Meeting Notes

At the SF Freebase Meetup on January 13th, 2010, Jamie Taylor briefly described WordNet, the lexical database of words developed by George Miller and colleagues at Princeton. Jamie recently put WordNet 3.0 into Freebase, an open symantic database created by Metaweb Technologies. The aim of the Freebase project is to enlist a global community and to include much of the world’s knowledge in a relatively coherent and well-structured form in a huge database that everyone can access. The inclusion of WordNet is a powerful addition to the substantial body of information already in Freebase.
