Encord Computer Vision Glossary
Natural language processing (NLP) is a subfield of artificial intelligence (AI) that deals with the interaction between computers and human (natural) languages. It involves the use of algorithms and statistical models to enable computers to understand, interpret, and generate human language. NLP is an important tool in AI, and is used in a wide range of applications including language translation, text classification, and chatbots.
In NLP, there are a number of significant difficulties, such as syntactic ambiguity, semantic ambiguity, and contextual ambiguity. Syntactic ambiguity describes the situation where the same words might signify different things depending on the context and sentence structure. Words can have different meanings depending on the context in which they are used, which is known as semantic ambiguity. The term "contextual ambiguity" describes how a word or phrase's meaning can vary depending on the context in which it is used.
What is NLP used for?
NLP algorithms use methods like part-of-speech tagging, named entity recognition, and sentiment analysis to deal with these problems. Identifying each word's function in a sentence, such as that of a noun, verb, or adjective, is known as part-of-speech tagging. Identification and extraction of named entities from a text, including persons, companies, and locations, is known as named entity recognition. Finding the sentiment that is being expressed in a text—be it good, negative, or neutral—is known as sentiment analysis.
NLP is a complex and active area of research, and new techniques and approaches are being developed to improve the accuracy and effectiveness of NLP algorithms. It is an important tool in AI, and is widely used in a range of applications including language translation, text classification, and chatbots.
