No, actually, I am referring to real time sentiment analysis of any kind - services such as http://www.dataminr.com/ or http://www.infotrie.com/ do this today mostly using online chatter, which you correctly point out probably would not be possible 5 years ago. However, real time news sentiment analysis would have been possible and relatively novel 5 years ago. For instance, Columbia's Paul Tetlock published a very interesting paper in the Journal of Finance in 2007 ago on the subject here: http://www0.gsb.columbia.edu/faculty/ptetlock/papers/Tetlock... (he used words from a Wall Street…

where we agree then, i think, is the fact that Twitter's just another datapoint. and from a statistical perspective, it cannot be considered representative of the wider population for any number of reasons, not least the fact that it's observational rather than a random sample. that said, it's an interesting proxy for examining questions of sentiment, and its predictive ability has been examined several times academically within specific contexts (elections and markets - e.g. this one by Cornell http://arxiv.org/abs/1010.3003) and found to be relatively accurate. so agreed, it's not…

Well sentiment analysis for news seems to have gained mainstream acceptance, with major providers like Reuters offering apps in that space. For twitter, etc. it's still a relatively new field. There's a paper on it at http://arxiv.org/abs/1010.3003

Here is the original paper - http://arxiv.org/pdf/1010.3003v1. The paper claims their code and data is open, but the link is broken and I was unable to find it by browsing their site...which seems to consist of mostly blank pages.
