Hi Samiya,
We have to be careful. This uses a technique usually referred to as
"sentiment analysis" and sometimes as "opinion mining". There is
extensive research on using it for things like election forecasting,
and the results are not exactly encouraging...
The idea is very interesting in itself, but the current methods are
quite limited. The common approaches are:
1) Using a dictionary where every word is annotated by humans in
terms of a score for each base emotion, do a lookup for the entire
text and present the final summation;
2) Using machine learning to train a model to recognize emotions
taking into account n-grams, instead of a single word.
The first method is very naif, many words have quite different
emotional valencies depending on context. It also fails to detect
sarcasm and other complexities of human language.
The second method could in principle work much better, but it
requires a large corpus of text annotated by emotional valencies.
Such corpora exist for specific applications, but models trained
that way tend to not work when you deviate too much from the context
of the training data. Religious texts are most likely too far away
from any useful training corpora.
Worse still, we are comparing translations from vastly different
cultures and linguistic backgrounds.
Some people suspect (me included) that producing a reliable
sentiment analysis algorithm requires solving the general problem of
AI.
Even that will not work. The AI will just add more opinions and more
emotions, and will make things more complex. AI will never solve any
problem, it will, if successful, only add problems. Like multicellular
organism have added problems to life, like how to go out of the ocean,
or how to go out of earth, etc.
Such technics will develop, but will not solve any problem, just add
new one, for the best and/or the worst.
Best,
Bruno
Best,
Telmo.
