PICCL
(This appears to be no longer supported)
PICCL (Philosophical Integrator of Computational and Corpus Libraries) offers a workflow for corpus building and builds on a variety of tools.
The primary component of PICCL is TICCL, a Text-induced Corpus Clean-up system, which performs spelling correction and OCR post-correction (normalisation of spelling variants etc).
