Redet is a tool for developing and executing regular expressions using any of more than 50 search programs, editors, and programming languages, intended both for developing regular expressions for use elsewhere and as a search tool in its own right. For each program in each locale, a palette showing the available constructs is provided. The properties of each program are determined by runtime tests, which guarantees that they will be correct for the program version and locale. Additional features include persistent history, extensive help, a variety of character entry tools, and the ability to change locale while running. Redet is highly configurable and fully supports Unicode.
Ruby/DICT is an RFC 2229-compliant client-side library implementation of the DICT protocol, written in the Ruby programming language. It can be used to write clients that access dictionary definitions from a set of natural language dictionary databases. rdict, a powerful CLI dictionary client built on Ruby/DICT, is included.
SCAN is a personal information retrieval framework, combining search, text analysis, tagging, and metadata functions for document collections management. SCAN is a component-based software using a number of plugins for specific features. The basic SCAN platform can be easily extended with plugins for different document formats and document location types.
SILGraphite (formerly OpenGraphite) is a project within SIL's Non-Roman Script Initiative and Language Software Development groups to provide extensible cross-platform rendering capabilities for complex non-Roman writing systems. It consists of a rule-based programming language, Graphite Description Language (GDL), that can be used to describe the behavior of a writing system, a compiler for that language, and a rendering engine that can serve as the backend of a text processing application. SILGraphite renders TrueType fonts that have been extended by means of compiling a GDL program. It is currently being integrated into Gecko/Mozilla through the SILA project, a GNU/Linux port is also underway, and there are plans for OpenOffice.org and Abiword integration.
Saxogram is a script which generates vocabulary lists from texts written in foreign languages. So far it has dictionaries for Latin, German, and Italian. Saxogram was written with extensibility in mind. Thus, other languages can be "plugged in" as modules. All that is needed is a dictionary and a small amount of code. The purpose of the program is to speed up language learning. Too much time is spent looking up every third word. This isn't practical when learning a new language. Generating a vocabulary list that can be used in parallel to ones reading is helpful.
SenseClusters is a natural language processing package that allows you to cluster similar contexts or to identify clusters of related words. It supports its own native methods based on first and second order representations of context, and also supports Latent Semantic Analysis. It is fully unsupervised, and can automatically discover the optimal number of clusters in your text. SenseClusters is a complete system that takes users from preprocessing of raw text to providing clustered output.
