Canonicalizing the deutsches Textarchiv

Virtually all conventional text-based natural language processing techniques – from traditional information retrieval systems to full-fledged parsers – require reference to a fixed lexicon accessed by surface form, typically trained from or constructed for synchronic input text adhering strictly to contemporary orthographic conventions. Unconventional input such as historical text which violate...

Historical document collections present unique challenges for information retrieval.

Hardware register windows and compiletime or link-time global register allocation are ways to do this. A measure of the effectiveness of any of these register management schemes is how thoroughly they manage to remove loads and stores. This measure also must count extra loads and stores t...
