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.

NetMath project is a web browser which allows Web pages to contain modifiable calculations.
It has built-in plotting engines and the ability to communicate with computation servers.
This makes it possible to do local graphics, zooming and panning, while taking advantage of sophisticated computational programs.
Documents contain active and editable items, and the results of computations appear in the document.
Main features:
- :expand((x+y+z)^5) gives Result.
- factor(f) (the value f above is maintained) evaluates to Result.
- 500! produces Result
- factor(154784717804734665298299) produces a list of factors and multiplicities Result

UberImaging allows you to control the disk imaging process of several workstations on a network without having to leave your computer.

You can wake up the workstations, image hard drives, and shut them down, all via a simple and easy to use GUI.

UberImaging program takes advantage of PXE and Wake-On-Lan technology in concert with various open source programs such as udpcast to give you remote control of the entire disk imaging process.

mod_murka creates a convenient apache, xml, xsl based web publishing environment. It manages caching of static html pages and integrates nicely with Tomcat for dynamic pages to provide a flexible, high performance MVC development framework.

How does it work?

Murka is an apache module (mod_murka). It performs XML and XSL processing for both static and dynamic pages.

For static pages it intercepts an http request at a very early stage of apache request processing and if the requested file has .html type performs the following steps:

1. Checks if file exists. If it exists returns control to standard apache request processing.
2. If the file does not exist looks for xml file in the same directory and with the same name (but with .xml extension). For example if the request file had a name test.html the xml file name would be test.xml.
3. Processes the xml file to find the location of the corresponding xsl stylesheet.
4. Calls Xalan XSLT engine with found xml and xsl files as parameters to produce an html file.
5. Saves html file at the requested location (test.html in the sample case).
6. Returns control to apache

Next time when the same html file is requested it would exist as a plain html and no Murka processing would be necessary. The above procedure results in implicit html cache building for all requested html files. If any of the xml data files or presentation stylesheet xsl files changes, one just needs to delete the corresponding html file (clear cache) and Murka would build the updated html file automatically. Also Murka can automatically regenerate html files if xml data has been changed.

For dynamic pages it does a quick XML/XSL transformation of the XML content generated by java application and sends to a browser the resulting HTML page. That makes a full separation of business and presentation logic where java application (business logic) and presentation (XSL) can be developed by different people with practically no overlap and provides a nice alternative to jsps. The major advantage of this approach compared to doing XSL transformations in java is a huge performance gain due to much faster XSLT processing in C.

Dynamic stylesheet linking

One of the most important features of Murka is its ability to make a rule based association of a single xml and xsl file with multiple html files or a single xml file with multiple style sheets and multiple html files. Both scenarios are very common in web development. The first one occurs when there is some xml data and it should be displayed in a standard way but cached as separate html files for different subsets of xml data.

A standard example for a content publishing site would be multi page articles: it is natural to store the text of an article in a single xml file but each page should be cached as a separate html file. The second scenario is when the same content should be displayed in different styles, for example a page with a printable version of an article. To deal with both cases Murka uses a single rule: the dash (-) in a file name has a special meaning. If the file name in a URL contains dash Murka adds to steps 2 and 3 from the above list the following additional logic:

1. It takes the part of the file name before - and looks for an xml file with that name. If the xml file exists it uses this xml file, otherwise it tries the full name with - (so that to support meaningless - just as part of the filename).
2. It first looks for a stylesheet the name of which combines the name it finds in the xml file and the second (after -) part of the file name in the URL. It uses this stylesheet if it finds it, otherwise it uses the "default" stylesheet defined in the xml file.

In both cases the value of the "after-dash" part of the file name is assigned to a special global variable with a name Sys_NamePar that is passed to the stylesheet and can be used there.

All that might sound complicated but it really is not. Murka comes with a fully functional example which shows how it works and explains everything in detail.

Nux is an open-source Java toolkit making efficient and powerful XML processing easy. It is geared towards embedded use in high-throughput XML messaging middleware such as large-scale Peer-to-Peer infrastructures, message queues, publish-subscribe and matchmaking systems for Blogs/newsfeeds, text chat, data acquisition and distribution systems, application level routers, firewalls, classifiers, etc.
Have you ever tried to take advantage of a robust and natural commodity Java tool set for XML, XQuery, XPath, schema validation, binary XML, fuzzy fulltext similarity search and related technologies, yet were not ready to accept a significant performance penalty?
Chances are most tool sets turned out not to be particularly robust and natural, that they incurred dramatic penalties when used in straightforward manners, and that their complex idiosyncracies had a strong tendency to distract from the real job and use cases you wanted to get done in a timely manner.
Nux helps to avoid XML nightmares, enabling you to mix and match powerful main-memory XML tools that fit your needs, in natural, straightforward, seamless, effective and standards compliant manners.
Nux reliably processes whatever data fits into main memory (even, say, 250 MB messages), but it is not an XML database system, and does not attempt to be one.
Nux integrates best-of-breed components, containing extensions of the XOM, Saxon and Lucene open-source libraries.
