   • how words are used to form phrases e.g. 'the' before a noun
   • POS tagging
     • learn the equation!
   • Parsing
     • CFGS and chart parsing
     • Dependency structures (arcs)
       • dependency parsing (oracle)
   • Realisation
     • inverse of parsing

3. Semantics

   • Compositional
     • sentences and sentence structure
     • lambda calculus, FOPL
       • inference
   • Lexical
     • individual words
     • word sense disambiguation
     • inference
     • semantic relations e.g. homonyms
     • WordNet
     • distributional semantics
       • vectors (words occurring in same context)
         • cosine similarity
       • neural networks

4. Pragmatics

   • meanings in context
   • Context processing
     • anaphora resolution
     • summarising
       • generation of referring expressions
   • discourse structuring

5. Evaluation
