Diogenes is a tool for searching and browsing the Latin and ancient Greek texts published on CD-ROM by the Packard Humanities Institute and the Thesaurus Linguae Graecae. It comes as an easy-to-install stand-alone application for GNU/Linux, Mac OS X, and Windows, based on the Firefox browser (i.e. Xulrunner). Alternatively, it can be installed by a network administrator as a server on a local network, and users then access it via an ordinary Web browser. There is also a command-line tool which can optionally format output as LaTeX instead of HTML.
The Computational Linguistics Toolset is a set of tools for computational linguistics. It contains re-usable code for cleaning, splitting, refining, and taking samples from corpora (ICE, Penn, and a native one), for tagging them using the TnT-tagger, for doing permutation statistics on N-grams (useful for finding statistically significant syntactical differences between any two sets of tagged texts), and various examination-tools. The tools themselves are well documented.
