The(Semantics(of(Sentiment1


This unique dog or chicken house was made with green practices in mind.

Appreciation2Valuation1

Oh, and on principle I hate extremists / zealots of any ilk.

Affect2Affection1

Oh and Spooks, … with this really tough and sexy old lady in it, kicking ass.

Judgement2Tenacity1

The(Semantics(of(Sentiment1


Other(Key(Pieces1•  Modality

o  Maybe my throat will feel better o  The burgers are probably good but I went with the fish tacos.

•  Evidentiality o  Why are people always so angry? You're trying to prove that your mean

and it isn't cute nor do you need to be on a social website. o  -__- and she thinks that it's funny. BUT IT'S NOT!!!

•  Sarcasm o  Nice to see Oakland Police attacking protesters again. Of course, it was

"agitators" at fault, not out of control cops.

•  Inferred sentiment o  College Without Weed Is Like A Notebook & No Pen..
