Sentiment Classification - Objectivity Indeed!

Found two different reviews of a 'sentiment classification' paper that illustrate the difficulty of trying to classify sentiment. The first,

Software Sorts Out Subjectivity
"It's easy for people to tell whether a review is positive or negative. It's much harder for computers because they have neither feelings nor understanding. Software that leaves out objective sentences is better at the task than systems that churn through whole documents.

Researchers from Cornell University have devised a way to improve sentiment classification that sidesteps having to deal with meaning by instead concentrating on context. Their method weeds out neutral sentences in order to make the overall sentiment more obvious."

The problem is that 'sorting out' subjectivity doesn't help to define the context better, on the contrary, those 'neutral' clues are essential to the context.

The other review does a better job of explaining what the researchers at Cornell had actually done. Separating the subjective and objective phrases and using pattern recognition to determine whether a positive or negative context of a review is present. The authors point out the difficulties encountered in the simplest + or - sentiment classification. Interesting research, but light years away from "filtering search results" or "tracking attitudes".
