Here are the areas I've been researching, some things I've read and some open source packages...

Nearly all text processing starts by transforming text into vectors: http://en.wikipedia.org/wiki/Vector_space_model

Often it uses transforms such as TFIDF to normalise the data and control for outliers (words that are too frequent or too rare confuse the algorithms): http://en.wikipedia.org/wiki/Tf%E2%80%93idf

Collocations is a technique to detect when two or more words occur more commonly together than separately (e.g. "wishy-washy" in English) - I use this to group words into n-gram tokens because many NLP techniques consider each word as if it's independent of all the others in a document, ignoring order: http://matpalm.com/blog/2011/10/22/collocations_1/

Update (2019-05-06): The Broadcom wireless card in the MacBook Pro works and can be crammed into the Air.

Update (2015-12-04): This document used to be very lengthy as there were many manual steps required to get OpenBSD and Mac OS X working together through Boot Camp Assistant (BCA), which created a hybrid MBR and enabled a legacy BIOS emulation mode which older versions of Windows (and OpenBSD) required. Newer Macbooks stopped supporting older versions of Windows through BCA and now only support Windows 10 since it uses GPT and UEFI. However, now that newer versions of OpenBSD support GPT and UEFI, Boot Camp Assistant is no longer needed at all to boot OpenBSD.

OpenBSD works pretty well on at least the Mid-2011 Macbook Air (A1370, SandyBridge) and Mid-2013 Macbook Air (Haswell). The new KMS code in 5.4 brings up the MBA's eDP display in 1366x768 with backlight
