OmegaT is a translation memory application intended for professional translators. It does not translate for you (software that does this is called "machine translation"). It features fuzzy matching, match propagation, simultaneous processing of multiple-file projects, simultaneous use of multiple translation memories, and external glossaries. Document file formats include plain text, HTML, and OpenOffice.org/StarOffice. It has Unicode (UTF-8) support (can be used with non-Latin alphabets). It is compatible with other translation memory applications (TMX Level 1).
OpenEphyra is a question answering (QA) system. It retrieves answers to natural language questions from the Web and other sources. OpenEphyra comes with implementations of algorithms that proved effective in Carnegie Mellon's Ephyra system, which participated in the TREC evaluations. It is platform independent and can be set up in just a few minutes. The goal of this project is to give researchers the opportunity to develop new QA techniques without worrying about the end-to-end system.
PolyGen is a program for generating random sentences according to a grammar definition, that is following custom syntactical and lexical rules. Formally, it is an interpreter of a language itself designed to define languages, where to interpret means executing a source program in real time and eventually outputting its result. Here, a source program is a grammar definition. The execution consists of the exploration of such grammar by selecting a random path, and the result is the sentence built on the way.
PottyMouth transforms completely unstructured and untrusted text to valid, nice-looking, completely safe XHTML. PottyMouth is designed to handle input text from non-technical, potentially careless, or malicious users. It produces HTML that is completely safe, programmatically and visually, to include on any Web page. You don't need to make your users read any instructions before they start typing. They don't even need to know that PottyMouth is being used.
Pure PHP Spell Check performs spell-checking of text using only base PHP functions, without using specific spell check PHP extensions such as aspell or pspell. The class uses a dictionary that is implemented as an array-based binary search table. The binary search table declaration is saved to a file for speed and can be updated easily by the developer.
