Some Aspects Regarding Natural Language Processing

It is known that the key properties of every computer system interface is to be very friendly. What is more natural than a communication between human and machine realized in natural language? Natural language is a medium for human-machine interaction that has several obvious and desirable properties: it provides a means of accessing information in the computer independently of its structure and encodings, it shields the user from the formal access language of the underlying system and it is available with a minimum of training. There are many approaches regarding natural language processing but in this study, I focus my attention to DCG grammar, and shortly, ATN grammar. I have tried to present the main analysis that must be performed while processing a text: syntactic analysis, morphologic analysis, semantic analysis and pragmatic analysis.
