Free experienced synonym software for linux

Xapian is an Open Source Probabilistic Information Retrieval library, released under the GPL. Xapian iss written in C++, with bindings to allow use from other languages (Perl, Java, Python, PHP, and TCL are currently supported; Guile and C# are being worked on).
Xapian is designed to be a highly adaptable toolkit to allow developers to easily add advanced indexing and search facilities to their own applications.
If youre after a packaged search engine for your website, you should take a look at Omega, which is an application we supply built upon Xapian. But unlike most other website search solutions, Xapians versatility allows you to extend Omega to meet your needs as they grow.
Main features:
- Free Software/Open Source - licensed under the GPL.
- Highly portable - runs on many Linux, MacOS X, many other Unix platforms, and Microsoft Windows.
- Written in C++. Perl bindings are available in the module Search::Xapian on CPAN. Java JNI bindings are included in the xapian-bindings module. We also support SWIG which can generate bindings for 13 languages. At present those for Python, PHP4, and TCL are working. Guile and C# are being worked on.
- Ranked probablistic search - important words get more weight than unimportant words, so the most relevant documents are more likely to come near the top of the results list.
- Relevance feedback - given one or more documents, Xapian can suggest the most relevant index terms to expand a query, suggest related documents, categorise documents, etc.
- Phrase and proximity searching - users can search for words occuring in an exact phrase or within a specified number of words, either in a specified order, or in any order.
- Full range of structured boolean search operators ("stock NOT market", etc). The results of the boolean search are ranked by the probablistic weights. Boolean filters can also be applied to restrict a probabilistic search.
- Supports stemming of search terms (e.g. a search for "football" would match documents which mention "footballs" or "footballer"). This helps to find relevant documents which might otherwise be missed. Stemmers are currently included for Danish, Dutch, English, Finnish, French, German, Italian, Norwegian, Portuguese, Russian, Spanish, and Swedish.
- Supports database files > 2GB - essential for scaling to large document collections.
- Platform independent data formats - you can build a database on one machine and search it on another.
- Allows simultaneous update and searching. New documents become searchable right away.
As well as the library, we supply a number of small example programs, and a larger application - an indexing and CGI-based application called omega:
- The indexer supplied can index HTML, PHP, PDF, PostScript, and plain text. Adding support for indexing other formats is easy where conversion filters are available (e.g. Microsoft Word). This indexer works using the filing system, but we also provide a script to allow the htdig web crawler to be hooked in, allowing remote sites to be searched using Omega.
- You can also index data from any SQL or other RDBMS supported by the Perl DBI module. That includes MySQL, PostgreSQL, SQLite, Sybase, MS SQL, LDAP, and ODBC.
- CGI search front-end supplied with highly customisable appearance. This can also be customised to output results in XML or CSV, which is useful if you are dynamically generating pages (e.g. with PHP or mod_perl) and just want raw search results which you can process in your own page layout code.
Enhancements:
- This release adds support for spelling correction and synonym expansion.
- Some Btree tables are now optional, so opening a database is slightly quicker.
- The Xapian::NumberValueRangeProcessor class has been reworked to fix a design flaw.
- A few bugs have been fixed.
- Performance was improved in several cases.

RapidSVN is a cross-platform GUI front-end for the Subversion revision system written in C++ using the wxWidgets framework. RapidSVN also includes a Subversion client C++ API.
We want to build a best of breed visual client that utilizes the best features of clients from other revision control architectures. While being easy enough for users new to Subversion to work with it must also be powerful enough to make experienced users even more productive.
Main features:
- Simple - provides an easy to use interface for Subversion features
- Efficient - simple for beginners but flexible enough to increase productivity for experienced Subversion users
- Portable - runs on any platform on which Subversion and wxWidgets can run: Linux, Windows, Mac OS 9/X, Solaris, etc.
- Fast - entirely written in C++

Lexi project is a dict client and vocabulary builder.

Lexi is a dict client that also serves as a personalized vocabulary builder.

It caches definitions and has a persistent word list.

The interface is structured to be quick and easy and features synonym clicking, drag and drop word queries, and spelling suggestions.

Tao Linux is a project to build a free Linux distribution from the sources used in the Red Hat Enterprise Linux product line.
The target market is either experienced system administrators who would like freely available binaries of this code, or end users who are interested in experimenting with enterprise functionality.
Besides being mostly compatible with Red Hat Enterprise Linux 3, it also includes software packages such as Eclipse and clustering tools not found in the base RHEL products.
Main features:
- Yum used for updates
- Based on commercially produced Enterprise sources
- Many packages for Red Hat Enterprise Linux also run on Tao Linux
- Free as in speech and beer
- Security updates (in SRPM form, at least) available for seven years.

The Dead Souls MUD Library is a multi-user, text based adventure creation system.

Dead Souls project allows the user to build adventure games which can be played over the Internet simultaneously by many people. It is designed for both experienced and beginner MUD admins.

Eclipse is a set of C++ classes designed to give beginner developers a head start in developing their first games as well as more experienced developers who dont want to have to write code for mundane tasks like fonts, sprites, and image loading.

Eclipse 2D Game Engine provides bitmap fonts, window management, audio capabilities, image loading, error logging, and zip file support.

The GNU Hurd project is a set of servers running on top of the GNU Mach microkernel. Together they build the base for the GNU operating system.

Currently, Debian is only available for Linux, but with Debian GNU/Hurd we have started to offer GNU/Hurd as a development, server and desktop platform, too. However, Debian GNU/Hurd is not officially released yet, and wont be for some time.

The Hurd is under active development, but does not provide the performance and stability you would expect from a production system. Also, only about every second Debian package has been ported to the GNU/Hurd. There is a lot of work to do before we can make a release.

Until then, you can participate in the development if you want. Depending on your experience and time commitment, you can help us in many different ways. For example, we need experienced C hackers to develop and implement new features and to fix bugs and debug the system.

If you are not very experienced in C programming, you can still help: Either by testing the existing systems and reporting bugs, or by trying to compile some unported software you have experience with. Also writing documentation is important, or maintaining the web pages.
