I am playing with an excellent platform for knowledge acquisition and architecting: Protégé from stanford.edu.

My main interest is the creation of OWL knowledgebases, and the application of Description Logic. The KISS project is maybe my greatest effort in this area.

Protégé is an excellent system for the knowledge engineer, but it is not easy to extract fragment of your ontology in a “user friendly” presentation format. I guessed that a tool like Velocity, from the Apache Foundation, would be a great help, as it allows to create e “template” of your required output, and then fill it at runtime with the java objects from the OWL API.

So I written a simple plugin for Protégé, integrating the OWL API and Velocity. The plugin is open source, you can access it from its website.

Yes.. more samples can help people without specific programming skills. In the past monts I was really busy, having now the responsibility for two functions; I will do my best to providemore documentation. However, remember that Velocity, the tool at the core of the plugin, was intended primarily as a programming tool; it is based on the Java(TM) object model, so, a non-programmer, will find it a little bit tricky.

Modeling standards can be a great resource for System Management. Field Engineers often are more oriented towards “practical” tecniques, underweighting the help that a good model can contribute to a successful management practice.

While I was managing Information System, I have worked with the Tivoli suite – from IBM – and developed some modeling tecniques to represent system events and to analyse the requirements for monitorning consoles. There is a paper, describing this, not updated, but perhaps interesting. I published it online after receiving a lot of requests from the Tivoli mailing list.

Another approach is described in my recent KISS project – described in another post – where I tried to build a knowledge model of the Information System and the related security and compliance issues.

The project uses a Description Logic-based approach for the conceptual modeling of the information system.

During the project I have used several new (form me) technologies, like the OWL language, DL reasoners, and I found this approach really fascinating.

I had confirms that

  • the adoption of XML-based standards allows a great level of interoperability among different stuffs,
  • open source technologies allow innovation with smooth investment curves.

The project deliverables are a fundamental tool, in my Company, for Compliance Risk management (according to the Basel Committee definition), and the conceptual models were used as a design input for a commercial application for Compliance management.

There is a web page dedicated to the project. You can find also another working paper, on conceptualization of norms, in my website.

Welcome

October 6, 2006

I have just started this blog, as an english version of my hand-crafted Italian Web site at mcoletti.net.

The need of an english version of my website comes from the great majority of english-speaking visitors.

a presto!
