I want to know if is there any specific algorithm that can be followed to understand the meaning of a word/sentence/paragraph. Basically, I want to write a program that will take text/paragraph as input and try to find out what its meaning is. And thereby highlight the emotions within the text.
Also, if there is an algorithm to understand things, can the same algorithm be applied to itself? It reduces the quest further to a point where we become interested in knowing meaning of meaning OR rather definition of definition.
You want Natural Language Processing and Semantic Technology. This is still a flourishing area in computer science. Look at things such as a Semantic Reasoner. You can start with Jena. There are also other things you can look at such as Academic Thesis papers.
