Facebook members used to think pretty positively about Republican Vice Presidential Nominee, Sarah Palin. However, over the last few weeks, they have started thinking 50% more negatively. How do I know? Facebook started previewing the next generation of it’s obscure Lexicon service.
Essentially, the service combs through wall posts by Facebook members and performs aggregate analysis on the data similar to Google Trends. One of the more interesting analysis Facebook performs is “sentiment” tracking. Whenever a certain term is used in a wall post, it identifies whether the term was positive or negative.
The preview version only allows you to review a small set of topics though, fortunately, Sarah Palin is one of them. On August 29th, wall posts mentioning Sarah Palin were 80% positive or 20% negative. Now, wall posts are 30% negative, a 50% increase in negativity.
