A segmentação ou divisão de cadeias de caracteres pode sentença é útil em diversos contextos. O processo consiste de quebrar uma cadeia de caracteres supostamente contendo várias sentenças nas sentenças constituintes. Isso permite fazer análise de texto com a sentença sendo a unidade documental. Dessa forma, por exemplo, a associação de entidades (pessoas, locais, datas) torna-se mais realista visto que as entidades que tiverem alta associação são porque ocorrem nas mesmas sentenças.

but does not provide this model.3 Rotulação de partes do discurso
A rotulação de partes do discurso é muito útil em várias atividades baseadas em texto. É algo que pode ser utilizado para a construção de características. Agrupamento de documentos podem ser feito olhando apenas para os termos que sejam adjetivos, substantivos e verbos, por exemplo. O mesmo pode ser feito para criação de características para a modelagem preditiva de imóveis que pode considerar apenas a ocorrência das classes gramaticais acima mencionadas.
