Word Tree

An interactive Visual Concordance

 
 

One of the largest challenges concerning written word is to explore and understand large texts. Word Tree provides the interactivity and ease of use to do this. You just have to provide any text in natural language and Word Tree helps you analyze. More information is provided in this paper and on IBM Many Eyes

word tree?

We introduce the Word Tree, a new visualization and information-retrieval technique aimed at text documents. A word tree is a graphical version of the traditional "keyword-in-context" method, and enables rapid querying and exploration of bodies of text. In this paper we describe the design of the technique, along with some of the technical issues that arise in its implementation. In addition, we discuss the results of several months of public deployment of word trees on Many Eyes, which

provides a window onto the ways in which users obtain value from the visualization.

Word Tree Paper Abstract

The Program has been developed under Xcode. Because of its excessive use of Core Animation it is only available for Mac OS 10.5 and above. The source code including the Xcode project file is available for download.


Here I give a brief description of my program:

  1. •First you have to enter a text either by copying it in the provided textfield or open a textfile through the “Import Textfile” dialog

  2. •The program parses the given text and counts every word in it

  3. •It puts the 200 most occuring words in a Word Cloud (similar to the well known tag cloud) and displays it

MY implementation

  1. •You can decide whether to choose a word from the Word Cloud or enter any desired word into the textfield

  2. •The Word Tree is essentialy a Suffix Tree. Every word is a suffix and the whole tree is built up by these words and their childs. To keep track of the tree only the 30 most occuring children are displayed.

  1. •You can now explore the Word Tree by clicking on specific subwords. This word’s subtree and the preceeding words are now displayed. To return to the tree of your search term, just click on the “Reset” button on the upper left

  2. •By double-clicking on a specific word you build up a new word tree with this word as root node

  3. •You can every time start a complete new search by clicking ono the Word Cloud or the input window

Here. Just click on the download button to the right. The source code is also available, including the Xcode Project.
