phrasesused

Phrasesused is a term encountered in linguistics and natural language processing to denote the collection of phrases that appear in a given text, document, or corpus. It is not a formally standardized concept, but it is often used to describe the set of multiword sequences that have actually been used in the material being analyzed.

In practice, phrasesused refers to the phrases identified from the text, typically as n-grams or multiword expressions. The exact definition can vary by context: some analyses include all contiguous word sequences within a minimum and maximum length, while others filter by syntactic criteria, stopword handling, or lexicalized expressions. The concept is commonly used as a feature in language models, search systems, and textual analytics to capture common phrases and collocations.

Methodologically, phrasesused is derived through text processing steps such as tokenization, phrase extraction, and normalization. Extraction may rely on sliding windows to collect n-grams, statistical measures to rank salient phrases, and linguistic resources to confirm multiword expressions. Frequencies and relative weights of phrasesused can inform downstream tasks like topic modeling, genre classification, or readability assessment.

Examples of phrasesused depend on the source text. In a news article about climate policy, likely phrasesused include “climate policy,” “carbon emissions,” and “policy changes.” The label is data-dependent and can vary across languages, domains, and preprocessing choices.

Notes: phrasesused is not a universal standard term, and its exact meaning should be inferred from the surrounding methodology. See also n-gram, multiword expression, collocation, and corpus linguistics.
