Text segmentation is the process of dividing written text into meaningful units, such as words, sentences, or topics. The term applies both to mental processes used by humans when reading text, and to artificial processes implemented in computers, which are the subject of natural language processing.

- Text segmentation is the process of dividing written text into meaningful units, such as words, sentences, or topics. The term applies both to mental processes used by humans when reading text, and to artificial processes implemented in computers, which are the subject of natural language processing. The problem is non-trivial, because while some written languages have explicit word boundary markers, such as the word spaces of written English and the distinctive initial, medial and final letter shapes of Arabic, such signals are sometimes ambiguous and not present in all written languages. Compare speech segmentation, the process of dividing speech into linguistically meaningful portions.
- Unter morphologischer Analyse versteht man in der Computerlinguistik ein Verfahren, welches die morphologischen, syntaktischen und evtl. semantischen Eigenschaften von Wörtern ermittelt. Im Einzelnen können morphologische Analyseverfahren die folgenden Teilaufgaben lösen: Segmentierung, d.h. Aufteilung von komplexen Wörtern in freie und gebundene Morpheme. Zu letzteren zählen Präfixe und Suffixe. Lemmatisierung: Zurückführung eines einfachen oder komplexen Wortes auf sein Lemma und Ermittlung seiner syntaktischen Eigenschaften. Beispiel: Das Wort "Häusern" wird auf sein Lemma "Haus" mit den Eigenschaften {Nomen, Plural, Dativ} reduziert. Ermittlung der Wortstruktur; diese wird oft in Zusammenhang mit einer wortsemantischen Analyse bestimmt.
- 形態素解析(けいたいそかいせき、Morphological Analysis)とは、コンピュータ等の計算機を用いた自然言語処理の基礎技術のひとつ。かな漢字変換等にも応用されている。 対象言語の文法の知識(文法のルールの集まり)や辞書(品詞等の情報付きの単語リスト)を情報源として用い、自然言語で書かれた文を形態素(Morpheme, おおまかにいえば、言語で意味を持つ最小単位)の列に分割し、それぞれの品詞を判別する作業を指す。 以下は「お待ちしております」という文を形態素解析した例である (形態素解析ツールには「茶筌」を使用した)。
- Análise Morfológica é o ato de estudar cada uma das diversas palavras em uma frase independentemente, visando sua classe gramatical. Exemplo: A Wikipedia é uma enciclopédia livre. A artigo definido Wikipedia substantivo próprio, derivado, simples é verbo de ligação, 3ª pessoa do singular, presente do indicativo uma artigo indefinido enciclopédia → substantivo comum, derivado, simples livre. adjetivo adjunto adnominal
