Abstract
We present several extensions to the shallow text processor sprout, viz.,
- a fast imperfect unifiability test,
- a special form of sets together with a polymorphic lazy and destructive unification operation,
- a cheap form of negation,
- a weak unidirectional form of coreferences,
- optional context-free stages in the shallow cascade,
- a compile time type check,
- compile time transition sorting under subsumption,
- several output merging techniques, and
- a compaction technique for lexical resources.
