Abstract

We present several extensions to the shallow text processor sprout, viz.,

1. a fast imperfect unifiability test,
2. a special form of sets together with a polymorphic lazy and destructive unification operation,
3. a cheap form of negation,
4. a weak unidirectional form of coreferences,
5. optional context-free stages in the shallow cascade,
6. a compile time type check,
7. compile time transition sorting under subsumption,
8. several output merging techniques, and
9. a compaction technique for lexical resources.

The extensions have been found relevant in several projects and might be of importance to other systems, even to deep processing.
