Notes on Derivational morphology in NLP

Derivational morphology in natural language processing



Derivational Morphology

Derivation is the process of creating new words from a stem/base form of a word.

  • One of the most common ways to derive new words is to combine derivational affixes with root words (stems). The new words formed through derivational morphology may be a stem for another affix.

  • We would say, new words are derived from the root words in this type of morphology.
  • English derivation is one of the complex derivations. It is because of one or more of the following reasons;
    • Less productive. That is, a morpheme added with a set of verbs to make new meaningful words cannot always be added with all verbs. For example, the base word 'summarize' can be added with the grammatical morpheme '-ation' results in a word 'summarization' whereas this morpheme cannot be added with all the verbs to make similar effects.
    • Complex meaning differences among nominalizing suffixes. For example, the words 'conformation' and 'conformity' both derived from the word stem 'conform' but meanings are entirely different.

  • Derivation creates different words from the same lemma.
