Natural Language Processing (NLP) is a field of AI concerned with understanding, analyzing and using natural languages. This field is considered a difficult yet intriguing field of study since it is connected to how humans and their languages work.
Applications of the field include translation, speech recognition, topic segmentation, information extraction and retrieval, and a lot more.
Below we take a look at some algorithms in the field. Before we get right into it though, we will take a look at a very useful form of language, context-free languages. Even though they are a bit restrictive, they have been used a lot in research in natural language processing.
Below is a summary of the demonstration files in this chapter.
