Now in my title I put the word Analysis in “quotes” because true analysis requires a level of language dependent natural language processing which so far is beyond our grasp. But we think what we have is a good, powerful, practical and understandable capability.
The point is simple: we classify all articles as having either positive or negative sentiment. In other words are they saying nice positive encouraging happy things, or evil sucky, mean spirited and depressing things?
[To have a sense of why this is not something you can do with perfection, even if you are an intelligent human, tell me whether this sentence is positive or negative: "The King is dead! Long live the king!" See, it's not obvious ]
Articles are marked with a pretty little colored red dot if they are deemed negative and an pretty little green dot if they are positive.
Also there is a filter for showing only positive or only negative articles.
And finally, and most useful, you can write SmartFeeds to pick out positive and negative articles, meaning there’s a new condition that you can include, combining with other conditions, to select for positive or negative sentiment.
So how does all this work? Well you just turn it on, of course, and you are in business. The command can be found on the Tools menu, Settings submenu, Sentiment Analysis. Just click the checkbox and press OK.
If you are not reading English language blogs then you most certainly will have to tune it, and you might want to anyway, by choosing Advanced… from the Sentiments dialog box.
You will see a list of words that we have chosen to correspond to positivity and a set of words that we have chosen to mean negativity. You are welcome of course to change those around to include your own sense of what words are most useful there.
So there you have it. BlogBridge Sentiment Analysis. We hope you like it. Please let us know what you think. We are very proud of it!
As mentioned above, it is one of the various power features that are offered to our Publisher level subscribers.
