Introduction

Node Map tool is presented in order to give to the user a flexible and easy to use tool for ontology design within WS-Talk context

Thinkmap

  • Data visualization and data representation tool
  • Real time data interaction.
  • The client can be deploy as a ‘thin” web-based

client, standalone .exe or other modes.

  • Multiple Thinkmaps can be run simultaneous

and together to represent the same data.

  • Highly documented, with examples and

templates available

Thinkmap Problems

  • One way data flow (in standard edition),

that is the data can be flexible visualised, but once changes in the data representation are made, these changes cannot be committed permanently to the data source

NodeMap Visualization tool

  • We have design a simple node map, than

can be complementary to AKRA’s Concept Vocabulary Designer.

  • It can be run as standalone Java

application, should be needed a Java applet can be implemented.

Node Map Visualization Features

  • Start a new Concept Hierarchy and then

connect nodes

  • Import existing ontology to add, remove, or

re-organize information

  • Import relevant terms obtained from text

mining techniques applied to a relevant set of text, then organise these terms in a new ontology that can be saved in a relevant format to a text file or data base
