Interesting. I can definitely see the possibilities of this tool for PR purposes, but it looks like the algorithm used to determine positive, negative or neutral coverage could use some tweaking. Just did a keyword search of our institution and the three articles the search tagged as "negative" really weren't. Two were about a researcher's development of a new method to test for cancer, and the third was about an expert's availability to discuss space debris. Perhaps the algorithm screens for "negative" words (such as "cancer") then concludes that the story is negative. If that's the case, then a LOT of positive research stories could end up in the negative category.

That's valuable feedback - I hope FT Search is listening and not just limiting the learning to their own survey on the site. As Google learns daily, algorithms only take you so far. It will be interesting to experience the richness of semantic or people-powered search and filters. Will we have tools that learn? I wrote a couple of posts a while back on Artificial Intelligence agents as Conversation Agents for that reason - imagining what's next in Web technology.

Wow, suddenly the "power" and "quality" of Google Blog Search, Google News and other "news sources" suddenly become redunant against this news search facility, harbouring every bit of the visual and data based context I am wary of from a "WolframAlpha.com" (on the data side) or "SearchMe.com" (on the visual side) standpoint, but offering unique, and invaluable tools which provides far more superior results then that of any news search facility before it.

I am very excited for the future of Newssift.com, 100% relevant, reliable and verifiable, plus the added addition of the "Sentiment" of the article in the search options, just blows my mind.

Many thanks for the Newssift review and feeback.

We are certainly finding that part of our core audience are PR/IR professionals, for the ability to track news stories, mentions of companies or products, and the ability to refine and by sentiment and so we appreciate sharing this POV on Conversation Agent.

Newssift is actively listening to all feedback, from collecting surveys on our site, tracking twitter mentions, reading blog posts and comments, to even closely following the footsteps of how people are using the site. We believe all of this will help us to iterate quickly and often to make Newssift a relevant and useful tool.

In response to how we decipher sentiment, without knowing your query string, I can't specifically speak to your search or your experience. However, if you conduct a keyword search on Newssift for "cancer" and add "positive sentiment" you will see plenty of articles that are indeed positive sentiment.

I also like to show this search as an example of how our sentiment works and results:

Pollution + China + positive sentiment

In general when you refine by sentiment, you will see some outliers, but it should be generally robust as we are constantly tweaking the annotation to get it as close to perfect as possible.

We are excited to continue building Newssift into a powerful semantic tool to help you SIFT the news and gather insight as part of your daily workflow. And thank you for the feedback and please keep it coming.

@Josh - quality is key. We can now easily do quantity in search, but we are left wanting in many cases on the reliability of the information. This tool is beginning to take things a step further.

@Amy - thank you for jumping in and for helping answer Andrew's question. I like the idea of being able to see outliers and keep refining the search with more definition around terminology. it looks like the tool is based upon a combination of good automated data pull and people analysis.
