The task we set ourselves
Full text tagging, not just selected words
Tagging the sense in context, not just the word
Quantitative and qualitative analysis
Not task specific categories
Tag set should make sense (psycho)- linguistically
Flexible category set with hierarchical structure
Words and multi-word units e.g. phrasal verbs (stubbed out), noun phrases (riding boots), proper names (United States of America), true idioms (living the life of Riley)
