Interesting project, horrible presentation. The colour gradient on the graph is confusing - does green mean happy, blue unhappy, and the movie changes tone over time? Axes of the graph are not labeled, what are we looking at? But, those concerns are secondary. Bar graph seems a poor choice here, given the nature of the data. Given that there doesn't seem to be any correlation with time, the order of phrases doesn't s…

You're right about the graphs. The horizontal axis is the minutes of the movie though (on the second graph). Will get rid of the gradient and add labels!

Earlier quoted context omitted.

Brazil is a dystopian satire. I would wager that GP is asking about scenarios where there is significant ambiguity and/or situational/verbal irony.

I just gave it a try: https://www.crealdo.com/story/movie-sentiment/movies/30 Never seen the movie so I can't judge myself.

That seems like a plausible analysis, the movie becomes darker as it proceeds, though there's a false happy ending (which in some cases of ham-fisted editing is the only ending - I saw it aired on network TV in the US this way) followed by a much more somber closing.

One of the major problems with sentiment analysis is that it doesn't pick up on irony or subtext very well. Relying on word choice alone, one such analysis pinned "Fitter Happier" as one of the happiest Radiohead songs.

Edit: sorry, I misremembered - it actually handled "True Love Waits" pretty well. It did pick up "Fitter Happier" as one of the happiest, that's what struck me as strange.

Everyone realizes there outliers difficult to get right. Point is you can get quite far with a relatively naive approach.

Isn't "True Love Waits" detected as the most depressing? The happiest one is "15 steps".

That says True Love Waits is the most depressing song though.. am I missing something?

>We have a winner! “True Love Waits” is officially the single most depressing Radiohead song to date. Rightly so, given that it tied for lowest valence (0.0378) and ranked fourth for highest percentage of sad words (24%). If the numbers still don’t convince you, just listen to it.

Why does the graph go from green to blue?

Good question, I just thought it looked nice but maybe I shouldn't have

Cool! I thought it was an indication of sentiment at first, I was like oh yeah la la land gets sad towards the end. Cool endeavor!

Curious if you investigated other libraries or algorithms. have you seen this - i have been playing with it, seems reliable: https://github.com/cjhutto/vaderSentiment
