Getting to nuances of opinion

The marriage of semantic and sentiment analysis can provide a powerful tool for determining the import and meaning of a piece of information, industry sources agree.

Say a Ford marketing executive wants to check out current consumer attitudes toward a particular car model. A platform such as Expert System’s Cogito can semantically query various industry blogs and postings and come back with potentially relevant comments such as: “The seats of my ugly Ford Explorer are great.” Using a combination of semantic and sentiment analysis, it can then determine that “this is a positive judgment of seats, but not of the brand,” says Expert System Partner Luca Scagliarini (http://twitter.com/scagliarini).
