Artificial General intelligence (AGI) is a system with the cognitive abilities of a human, capable of performing a wide range of tasks and to apply this knowledge to solving unfamiliar problems without preparation. Artificial neural network (ANN) is a mathematical model, as well as its software or hardware implementation, based on the principle of organization and functioning of biological neural networks -- networks of nervous cells of a living organism. Computational linguistics (also: mathematical or computational linguistics) is a research area in the field of mathematical and computer modeling of intellectual processes in humans and animals for creation of artificial intelligence systems, which aims to use mathematical models to describe natural languages. However, in the latter the emphasis is not on abstract models, but rather on applied methods of describing and processing language for computer systems. The field of activity of computational linguists is developing algorithms and applied programs for processing language information. Linguistic annotation is one of the basic concepts of corpus linguistics.
