For example, in medicine, machines can infer a diagnosis based on previous diagnoses using IF-THEN deduction rules. Automated reasoning is a subfield of cognitive science that is used to automatically prove mathematical theorems or make logical inferences about a medical diagnosis. It gives machines a form of reasoning or logic, and allows them to infer new facts by deduction. NLP is concerned with how computers are programmed to process language and facilitate “natural” back-and-forth communication between computers and humans. A year later, in 1965, Joseph Weizenbaum at MIT wrote ELIZA, an interactive program that carried on a dialogue in English on any topic, the most popular being psychotherapy.

Natural language processing works by taking unstructured data and converting it into a structured data format. It does this through the identification of named entities and identification of word patterns, using methods like tokenization, stemming, and lemmatization, which examine the root forms of words. For example, the suffix -ed on a word, like called, indicates past tense, but it has the same base infinitive as the present tense verb calling. NLP is a field that deals with the interactions between computers and human languages. It’s aim is to make computers interpret natural human language in order to understand it and take appropriate actions based on what they have learned about it. Natural language generation is another subset of natural language processing.
