Free natural selection software for linux

Natural Language Toolkit is a suite of Python libraries and programs for symbolic and statistical natural language processing. NLTK includes graphical demonstrations and sample data.
It is accompanied by extensive documentation, including tutorials that explain the underlying concepts behind the language processing tasks supported by the toolkit.
Documentation:
A substantial amount of documentation about how to use NLTK is available from the nltk home page:
< http://nltk.sourceforge.net >
In particular, the NLTK home page contains three types of documentation:
- Tutorials teach students how to use the toolkit, in the context of performing specific tasks. They are appropriate for anyone who wishes to learn how to use the toolkit.
< http://nltk.sourceforge.net/tutorial/ >
- The toolkits reference documentation describes every module, interface, class, method, function, and variable in the toolkit. This documentation should be useful to both users and developers.
< http://nltk.sourceforge.net/ref/nltk.html >
- A number of technical reports are available. These reports explain and justify the toolkits design and implementation. They are used by the developers of the toolkit to guide and document the toolkits construction. Students can consult these reports if they would like further information about how the toolkit is designed and why it is designed that way.

Enhancements:
Code (major):
- changed package name to nltk
- import all top-level modules into nltk, reducing need for import statements
- reorganization of sub-package structures to simplify imports
- new featstruct module, unifying old featurelite and featurestructure modules
- FreqDist now inherits from dict, fd.count(sample) becomes fd[sample]
- FreqDist initializer permits: fd = FreqDist(len(token) for token in text)
- made numpy optional
Code (minor):
- changed GrammarFile initializer to accept filename
- consistent tree display format
- fixed loading process for WordNet and TIMIT that prevented code installation if data not installed
- taken more care with unicode types
- incorporated pcfg code into cfg module
- moved cfg, tree, featstruct to top level
- new filebroker module to make handling of example grammar files more transparent
- more corpus readers (webtext, abc)
- added cfg.covers() to check that a grammar covers a sentence
- simple text-based wordnet browser
- known bug: parse/featurechart.py uses incorrect apply() function
Corpora:
- csv data file to document NLTK corpora
Contrib:
- added Glue semantics code (contrib.glue, by Dan Garrette)
- Punkt sentence segmenter port (contrib.punkt, by Willy)
- added LPath interpreter (contrib.lpath, by Haejoong Lee)
- extensive work on classifiers (contrib.classifier*, Sumukh Ghodke)
Tutorials:
- polishing on parts I, II
- more illustrations, data plots, summaries, exercises
- continuing to make prose more accessible to non-linguistic audience
- new default import that all chapters presume: from nltk.book import *
Distributions:
- updated to latest version of numpy
- removed WordNet installation instructions as WordNet is now included in corpus distribution
- added pylab (matplotlib)
Enhancements:
Code:
- changed nltk.__init__ imports to explicitly import names from top-level modules
- changed corpus.util to use the rb flag for opening files, to fix problems reading corpora under MSWindows
- updated stale examples in engineering.txt
- extended feature stucture interface to permit chained features, e.g. fs[F,G]
- further misc improvements to test code plus some bugfixes
Tutorials:
- rewritten opening section of tagging chapter
- reorganized some exercises

Yet Another V4L Application (or yava for short) is lightweight v4l framegrabber with support for TrueType fonts and ftp-upload.
Yet Another V4L Application project is written in ANSI C.
It uses Andreas Schifflers excellent SDL_bgrab library for frame grabbing, SDL for internal image manipulation, SDL_ttf for TrueType font rendering, libcurl for ftp uploads and libpng for snapshot writing.
Main features:
- Lightweight, using pretty standard libraries
- Tuner support
- FTP-upload (active and passive modes)
- TrueType font rendering
- Text color (RGB) selection
- Vertical text positioning (top, center, bottom)
- Horisontal text positioning (left, center, right)
- Font selection and number of pts
- Snapshots in png
- Live viewer or console mode

Word Inspector project is a GTK frontend to Dict dictionary program.

The dict program allows you to search through one or more dictionary-like reference books for a word, then displays its definition.

Word Inspector expands that by allowing you to enter words to look up more easily, easily look up words that appear in the definition for another word, and automatically look up a word in the X Windows selection.

gfontsel program is a simple wrapper around the GTK+ 2 font selection dialog. It allows you to select a font.

The font name is written to the standard output in the GTK+ 2 font naming scheme.

Building and installing the program:

- Read the makefile. Change the install locations if you want.
- To build the program invoke make.
- To install the program, invoke make install *as root*.

If you dont like it, login as root, change to the source directory and run make uninstall. After that you can remove the source tree.

autocutsel project is a simple buffer in which any application can store text.
X servers use two schemes to copy text between applications. The first one (old and deprecated) is the cutbuffer. The other scheme is the selection and works differently.
There may be many selections in a single server. An application does not copy data in a selection, it "owns" it. When another application wants to retreive the content of a selection, it asks the owner.
Recent desktop applications (GNOME, KDE, ...) use two selections: the PRIMARY and the CLIPBOARD. The PRIMARY selection is used when you select some text with the mouse. You usually paste it using the middle button. The CLIPBOARD selection is used when you copy text by using, for example, the Edit/Copy menu. You may paste it using the Edit/Paste menu.
Windows VNC clients keep the Windows clipboard synchronized with the cutbuffer, but not with the selections. And since recent applications dont use the cutbuffer, the servers CLIPBOARD is never synchronized with Windows one.
Autocutsel tracks changes in the servers cutbuffer and CLIPBOARD selection. When the CLIPBOARD is changed, it updates the cutbuffer. When the cutbuffer is changed, it owns the CLIPBOARD selection. The cutbuffer and CLIPBOARD selection are always synchronized.
Since the VNC client synchronizes the Windows clipboard and the servers cutbuffer, all three "clipboards" are always kept synchronized. When you copy some text in Windows, the cutbuffer and the CLIPBOARD selection are updated. When you copy text on the server using either the cutbuffer or the CLIPBOARD selection, the Windowss clipboard is always updated.
Installation and Usage:
./configure
make
If you downloaded autocutsel from CVS, you first have to run ./autogen.sh to build the configure script.
If configure fails because it cant find X or Xaw libraries, you may have to install the devel packages of these libraries.
To install it (as root):
make install
To run it:
autocutsel
By default, autocutsel synchronizes the CLIPBOARD selection. You may want to use the PRIMARY selection instead, if your applications use Motif or another toolkit not using the CLIPBOARD. To do that, simply run
autocutsel -selection PRIMARY
Enhancements:
- A bug which occurred on 64-bit systems has been fixed.
- A workaround for OpenOffice.org writer has been implemented.
- A compilation problem on NetBSD has been fixed.
- A test suite has been added.
