El análisis de constituyentes es el proceso de analizar una oración dividiéndola en unidades gramaticales anidadas llamadas constituyentes. Ayuda a los sistemas de lenguaje natural a representar la estructura sintáctica, como sintagmas nominales, sintagmas verbales y cláusulas.
Dividing a sentence into smaller grammatical structures ("constituents"). A later part of the ML system, such as a natural language understanding model, can parse the constituents more easily than the original sentence. For example, consider the following sentence: My friend adopted two cats. A constituency parser can divide this sentence into the following two constituents: - My friend is a noun phrase. - adopted two cats is a verb phrase. These constituents can be further subdivided into smaller constituents. For example, the verb phrase adopted two cats could be further subdivided into: - adopted is a verb. - two cats is another noun phrase.
