That is really interesting (great link too!). As coders ourselves we've had the same experience: spinning up something simple is usually pretty straightforward.

That is really interesting (great link too!). As coders ourselves we've had the same experience: spinning up something simple is usually pretty straightforward. What we are a little more curious about is the ability to bring simple sentiment mining to non-coders (IE: your support or social media guy) via off the shelf tools.
- guylhem 14y agoBased on my experience the sensibility is good (ie it often gives a red flag when something happens) but the specificity is poor (ie there are many false positives). My theory at the time was that some kind of semantic sliding was happening and led "sentiment loaded" words into common use, while removing their specific sentiment load (#)- which is why I tried TF-IDF, but even then the results where not that good and I was too lazy to dig into grammar analysis to correct for the other possible bias (negations and other complexities such as irony becoming more frequent) (Are you part of the team behind this product? Would you have some comments about sensibility and specificity of your results?) (#) : ex : teen talk ("OMG it's so crazy and fabulous!") is full of words that may have indicated a strong sentiment, but which that are devoid of it in the given "teen talk" context.
