[Corpora-List] EmoText - Software for opinion mining and lexical affect sensing

[John F. Sowa]

Alexander,

I tried the default movie review with both the naive Bayes and
the SVM options.  For most of the options, both versions evaluated
the review as average (2.5 stars).

But with the option "with a dataset containing grammar features",
naive Bayes dropped to 1.5 stars, and SVM dropped to 0.5 stars.

That's an impressive difference.  Could you say something more about
how the system uses grammar features to derive those results.

In particular, it would be helpful to select some sentences from
that default text for which the grammar features make a significant
difference and say how that difference was derived.

For the semantic demo, I tried the following two sentences:

    "This demo is a lot of crap."  Rating: neutral.

    "This demo gets rid of the crap."  Rating: low-neg.

That's the reverse of what one might expect.

John
