NLP is concerned with natural or human languages - languages which we human beings use for day to day communications, as against artificial languages such as computer and robot programming languages [13]. The terms Natural Language Processing and Computational Linguistics have been used interchangeably. Natural Language Processing started off as a part of Artificial Intelligence (AI), a discipline with two broad goals - 1) to understand the nature of human intelligence and 2) to build intelligent systems [13]. NLP is a technology that concerns with natural language generation (NLG) and natural language understanding (NLU) [13, 15] NLG makes sure that generated text is grammatically correct and fluent. Most NLG systems include a syntactic realizer to ensure that grammatical rules such as subject verb agreement are obeyed and text planner to decide how to arrange sentences, paragraph and other parts coherently. The best Known NLG application is machine translation. NLU consists of at least of one the following components; tokenization, morphological or lexical analysis, syntactic analysis and semantic analysis
