What Is RDF? Tim Bray 2001January 24, 2001 Spanish Translation available here. This article was first published as "RDF and Metadata" on XML.com in June 1998. It has been updated by ILRT's Dan Brickley, chair of the W3C's RDF Interest Group, to reflect the growing use of RDF and updates to the specification since 1998.Word TreeA word tree is a visual search tool for unstructured text, such as a book, article, speech or poem. It lets you pick a word or phrase and shows you all the different contexts in which it appears. The contexts are arranged in a tree-like branching structure to reveal recurrent themes and phrases. The image above is a word tree made from Martin Luther King's famous "I have a dream" speech, using the search term "I." Font sizes show frequency of use, so you can see that among King's many uses of "I," the most frequent context is the phrase "I have a dream." With the right phrase, a word tree can reveal the heart of a data set.

Backbone.js on Rails talk - Jason MorrisonOn Tuesday, September 20, I gave a talk at the New Hampshire Ruby Users Group on Backbone.js on Rails. I’ll be giving a very similar talk on Tuesday, October 11 at boston.rb and a version more targeted to front-end developers on Wednesday, October 26 at the Boston Front End Developers meetup I have posted the Backbone.js on Rails slides online, and the slide source is on my GitHub. As an aside, I’m using landslide for the slides – I love the resulting HTML and interface, though I’ve heard great things about deck.js. People found the resources sections useful.
What Is RDF? Joshua TaubererJuly 26, 2006 Editor's Note: "What Is RDF" was originally written by Tim Bray in 1998 and updated by Dan Brickley in 2001. Recently it seemed like time for another update, particularly to relate RDF and the Semantic Web to the cutting edge of web development. We've republished the original in a new location and offer the following update. I'll leave to you, dear reader, the task of deciding how well Joshua Tauberer has accomplished the task of updating a classic. -- Kendall Grant ClarkText Analysis ToolsDefinition: Text analysis software enables users to determine the frequency with which words or phrases are used, create concordances, view words in context, and otherwise study patterns in texts.
