I believe that machines can not accurately read emotions. They can read words that signify emotions, but I don’t accurately think they can “read” it. Reading emotions require understanding how those emotions feel, and currently machines can’t do that. We can program them to look for words that we know convey emotions but until they can accurately feel emotion, and experience the things that help humans to evoke emotion then I don’t think they can accurately read it. In addition there are words that can be interpreted ambiguously and those words cannot be distinguished by a computer. Sure context can help but it still does not get to the root of the meaning.
With my corpus I have had a hard time using these methods to analyze emotions. From prior knowledge I know the emotion of each book of the Aeneid, the Odyssey, and the Iliad and what Jigsaw returned to me was almost overwhelmingly the opposite. All three of these works are filled with anger and remorse and Jigsaw returned to me all happy emotion readings. Maybe I misunderstood all three but I find that highly unlikely as I have read them all several times in different settings and have come to the same general conclusion every time. This leads me to believe that as I’ve said before computers have a hard time understanding emotion.
