Tasks of natural language processing

use of software for language translation

type of expression whose reference depends upon another referential element

use of natural language processing, text analysis and computational linguistics to identify and extract subjective information in source materials

approach to machine translation in which a large neural network is trained to maximize translation performance

In linguistic morphology and information retrieval, stemming is the process of reducing inflected (or sometimes derived) words to their word stem, base or root form—generally a written word form. The stem need not be identical to the morphological root of the word; it is usually sufficient that related words map to the same stem, even if this stem is not in itself a valid root. Algorithms for stemming have been studied in computer science since the 1960s. Many search engines treat words with the same stem as synonyms as a kind of query expansion, a process called conflation.

computer-based method for shortening a text

Lemmatization (or less commonly lemmatisation) in linguistics is the process of grouping together the inflected forms of a word so they can be analysed as a single item, identified by the word's lemma, or dictionary form.

research area in computer science

extraction of named entity mentions in unstructured text into pre-defined categories

process of identifying the grammatical type of words in a text

a device common to works to offer an instant translation of any language. As a convention, it is used to remove the problem of translating between alien languages

process of dividing written text into meaningful units, such as words, sentences, or topics
