  3. Morphology in applications • Information retrieval / search: normalization • Proofing / disambiguation: vocabulary coverage • Language understanding / generation: decomposition, recomposition, reduction of data sparseness

  4. Morphology in applications and its ENEMIES! • Information retrieval / search: normalization • Proofing / disambiguation: vocabulary coverage • Language understanding / generation: decomposition, recomposition, reduction of data sparseness Arbitrary choice? Reliable? Appropriate? English? Phrases? Internet?

  5. Morphology in research • Traditional linguistic research: creation of (descriptive) grammars • Computational linguistic: algorithms for morhological analysis, machine learning • Language acquisition: machine learning vs. learning in nature

  6. Morphology in research and lots of CONFUSION... • Traditional linguistic research: creation of (descriptive) grammars • Computational linguistic: algorithms for morhological analysis, machine learning • Language acquisition: machine learning vs. learning in nature Historical development? Too regular? Unlearnable? Concatenation vs. paradigms Information theory or structuralism or embodied cognition? The beauty is in the eye of the beholder...

  7. Discovered a prefix paradigmfor English?

  8. Thank you and good luck!
