Graphs and Dijkstra algorithm
I wrote this article in order to share the source-code of a basic implementation of the the Dijkstra's algorithm. Readers after full-featured, industrial-strength Java implementations of Dijkstra's shortest path algorithm should look into JGL and JDSL, among others (Thanks to Renaud Waldura for the links taken from his article). Important : Update from the 04/03/2004 : there was a bug in the PriorityQueue class which was generated inaccurate results. I'd like to thank Olivier Daroux for telling me about the problem and fixing it. I have updated the source-code and it is available for download.

THINK - Overview
Overview | People | Collaborators | Sponsors | Publications | Tools The THINK (Tactical Human Integration of Network Knowledge) project is a collaborative effort of Pearson’s Knowledge Technologies (PKT) division, Carnegie Mellon University’s Center for the Computational Analysis of Social and Organizational Systems (CASOS) and the MA&D Operation of Alion Science and Technology. The goal of the effort is to develop an integrated toolset that supports different but complementary analysis methods. The toolset addresses three inter-related aspects of human integration of networked knowledge: CMU’s tools for extracting and analyzing dynamic network structure; PKT’s tool for understanding and assessing the content of communication over a given network; and Alion’s tool for modeling and exploring network performance for given team structures, technologies and human cognitive behaviors.

Dot2WPF - a WPF control for viewing Dot graphs. Free source code and programming articles
Introduction I am presenting a WPF control for viewing graphs rendered by GraphViz (Dot). The DotViewer control has the usual navigation -- i.e. zoom, drag, scroll -- and supports hit testing on nodes, which is used for displaying tooltips. In the first place, this article should show you how easy it is to do "owner drawn graphics" in WPF. As it turns out, the viewer of this sample also has some advantages over existing viewers:

Open source data structs and semantic frameworks
The Open Semantic Framework is a complete and integrated software stack that combines external open source components with specific enhancements developed by Structured Dynamics. OSF is a complete foundation to bring semantic technology capabilities to the enterprise. OSF has a variety of potential applications from enterprise information integration to collaboration networks and open government.

Volkswagen’s Use of structWSF in their Semantic Web Platform at Frederick Giasson
This story has been published by Jennifer Zaino’s in her article: Volkswagen: Das Auto Company is Das Semantic Web Company! I can now talk about this project that uses some pieces of the framework that we have been developing for more than 3 years now. The Objective Volkswagen’s main objective behind the development of the next version of their Web platform started by improving their online search engine, but as William Greenly mentioned, it quickly became a strategic decision: "So the objectives were about site search and improving it, but in the long-run it was always the idea to contextualize content, to facet content, to promote it in different contexts." The objective is to create a platform that gives them the flexibility to leverage all the data assets they own.
