Types of Word Segmentation

Types of Word Segmentation

1. Orthographic Segmentation
   • Splits by written form.
   Example:
   cogit + ate

2. Morphological Segmentation
   • Splits into meaningful morphemes.
   Example:
   cogit- + -ate

3. Etymological Segmentation
   • Splits according to historical origin.
   Example:
   co- + ag- + -it- + -are

4. Phonological Segmentation
   • Splits into syllables or sound units.
   Example:
   cog + i + tate
   IPA: /ˈkɒɡ.ɪ.teɪt/ → /kɒɡ/ + /ɪ/ + /teɪt/

5. Phonemic Segmentation
   • Splits into individual phonemes.
   Example:
   /k/ + /ɒ/ + /ɡ/ + /ɪ/ + /t/ + /eɪ/ + /t/

6. Graphemic Segmentation
   • Splits into written symbols (letters or graphemes).
   Example:
   c + o + g + i + t + a + t + e

7. Syllabic Segmentation
   • Splits into syllables.
   Example:
   cog + i + tate

8. Lexemic Segmentation
   • Identifies lexical stems and affixes.
   Example:
   cogit- + -ate

9. Semantic Segmentation
   • Splits by meaning-bearing components.
   Example:
   together + drive + intensive action

10. Root–Affix Segmentation
    • Separates root from prefixes and suffixes.
    Example:
    co- + ag- + -it- + -are

11. Stem–Affix Segmentation
    • Separates stem from inflectional/derivational affixes.
    Example:
    cogit- + -ate

12. Historical (Diachronic) Segmentation
    • Splits according to historical stages of development.
    Example:
    agere → agitare → cogitare → cogitate

13. Computational Segmentation
    • Splits using statistical or rule-based NLP methods.
    Example:
    cogit + ate

14. Prosodic Segmentation
    • Splits by stress and rhythm.
    Example:
    ˈcog | i | tate
