NLP techniques Definitions

  • A

    AI (artificial intelligence)

    AI (artificial intelligence) is the simulation of human intelligence processes by machines, especially computer systems. These processes include learning (the acquisition of information and rules for using the information), reasoning (using rules to reach approximate or definite conclusions) and self-correction.

  • artificial personality (AP)

    An artificial personality (AP) is a collection of characteristics, tendencies and behavioral quirks assigned to a chatbot, digital assistant, robot or video game character.

  • C

    cognitive computing

    Cognitive computing systems use computerized models to simulate the human cognition process to find solutions in complex situations where the answers may be ambiguous and uncertain.

  • cognitive modeling

    Cognitive modeling is an area of computer science that deals with simulating human problem-solving and mental processing in a computerized model.

  • computational linguistics (CL)

    Computational linguistics is the application of computer science to the analysis, synthesis, and comprehension of written and spoken language. Computers that are linguistically competent not only help facilitate human interaction with machines and software, but also make the textual and other resources of the internet readily available in multiple languages.

  • I

    intelligent agent

    An intelligent agent is a program that can make decisions or perform a service based on its environment, user input and experiences.

  • L

    lemmatization

    Lemmatization is the grouping together of different forms of the same word.

  • M

    machine learning (ML)

    Machine learning (ML) is a category of algorithm that allows software applications to become more accurate in predicting outcomes without being explicitly programmed.

  • N

    natural language generation (NLG)

    Natural language generation (NLG) is the use of artificial intelligence (AI) programming to produce written or spoken narrative from a dataset.

  • natural language understanding (NLU)

    Natural language understanding (NLU) is a branch of artificial intelligence (AI) that works to use computers to understand input made in the form of sentences in text or speech format.

  • S

    stemming

    Stemming is the process of reducing a word to its word stem that affixes to suffixes and prefixes or to the roots of words known as a lemma. Stemming is important in natural language understanding (NLU) and natural language processing (NLP).

  • T

    Turing Test

    A Turing Test is a method of inquiry in artificial intelligence (AI) for determining whether or not a computer is capable of thinking like a human being.
