Task: Sentiment Analysis
Input (English): It is too bad that this is practically the only one of the kind. The aim is great, the contents are great, but the author does not know how to write a technical book. The author refers to concepts and terms that are yet to be defined or never defined at all. For example, at the very beginning, the author talks about "violet" and "purple". Am I the only one who did not know "violet" means a color of a single frequency, whereas "purple" is a color of combined frequencies? This is a No-No for mathematicians and scientists. For those of who are already familiar with Color Theory, the book must be a great assurance, articulation or enhancement of their existing knowledge, but for those who are new and try to learn as an artist, this is a nightmare. I am the latter kind. The only reason I could finish it was because I am familiar with fundamental physics and optics already.
Output (English): Negative
