Biaroza is a multi-dictionary system for human languages which aims to set a standard on such type of software. It works internally (and externally if you want so) in UTF-8. The software itself supports querying by particles, customizable in/out filtering, and interface mode (for using with another software) among other features.
Ciao is a complete Prolog system subsuming ISO-Prolog with a novel modular design which allows both restricting and extending the language. Ciao extensions currently include feature terms (records), higher-order, functions, constraints, objects, persistent predicates, a good base for distributed execution (agents), and concurrency. Libraries also support WWW programming, sockets, and external interfaces (C, Java, TCL/Tk, relational databases, etc.). An Emacs-based environment, a stand-alone compiler, and a toplevel shell are also provided.
Ellogon is a multi-lingual, cross-platform, general-purpose language engineering environment, developed in order to aid both researchers who are doing research in computational linguistics, as well as companies who produce and deliver language engineering systems. As a language engineering platform, it offers an extensive set of facilities, including tools for processing and visualising textual/HTML/XML data and associated linguistic information, support for lexical resources (like creating and embedding lexicons), tools for creating annotated corpora, accessing databases, comparing annotated data, or transforming linguistic information into vectors for use with various machine learning algorithms.
FramerD is a semi-structured object database integrated with a Scheme-based scripting language which supports multi-lingual programming (with pervasive Unicode), a stable module system for programming in the large, distributed applications (via an extensible RPC protocol), non-deterministic (PROLOG-like) evaluation for search and set operations, multi-threaded program execution, extensive tools for text and language analysis, built-in HTML/XML/MIME parsers, and intuitive (CGI- and FastCGI-based) Web scripting. The built-in object database robustly supports millions of objects and indexed access to those objects, both through disk files and networked servers.
The GCC XML Tree Node Introspector project consists of a patch to the gcc compiler to output the internal compiler tree nodes in RDF/XML and programs to process that RDF/XML. The tree nodes are complex data structures which represent the source code inside the compiler. Through these tree nodes, users are able to extract information from their programs that would be otherwise very difficult to obtain. Modules exist to store these nodes in Redland RDF using a Berkley database. The long-term goal of the project is create a high-level API that will make the programmatic manipulation of programs easier than it is now.
The GNU Talk Filters are filter programs that convert ordinary English text into text that mimics a stereotyped or otherwise humorous dialect. Some of these filters have been in the public domain for many years, but here they are provided as a single integrated package. The filters include austro, b1ff, brooklyn, chef, cockney, drawl, dubya, fudd, funetak, jethro, jive, kraut, pansy, pirate, postmodern, redneck, valspeak, and warez. This package provides the filters both as individual executables and collectively as a C library, so they can be easily embedded in other programs.
Hesperides is an adaptation for Mac OS X of Didier Willis' Dragon Flame, a dictionary for Sindarin (the grey-elven language, invented by J.R.R. Tolkien). It integrates Didier's Sindarin dictionary with a state-of-the-art interface and the Narmacil engine (to display the words using Tengwar).
