Natural Language Processing

Overview: The goal of Natural Language Processing (NLP) is to design and build a computer system that will analyze, understand, and generate natural human-languages. Applications of NLP include machine translation of one human-language text to another; generation of human-language text such as fiction, manuals, and general descriptions; interfacing to other systems such as databases and robotic systems thus enabling the use of human-language type commands and queries; and understanding human-language text to provide a summary or to draw conclusions. One of the easiest tasks for a NLP system is to parse a sentence to determine its syntax. A more difficult task is determining the semantic meaning of a sentence. One of the most difficult tasks is the analysis of the context to determine the true meaning and comparing that with other text.
