The Semantic WebToday we reach an important milestone in this series. We are crossing a great divide between familiar technologies such as XML, Unicode, URI, and RDF to the Web Ontology Language (OWL). This, my friends, is where things really start to get interesting because this is the point where the Semantic Web vision really starts to take form. Today, we present a screencast exhibiting Protégé — a free, open source ontology editor and knowledge-base framework developed by Stanford Center for Biomedical Informatics Research at the Stanford University School of Medicine. In this screencast, we show you how to develop a useful Semantic Web-ready application in just minutes. You will learn how to model a very simple ontology in OWL (the Web Ontology Language).

The Semantic Web In Part 2 of this series we reviewed Unicode, URI, and XML - three foundational technologies that permeate the existing Web and that are especially relevant to the emerging Semantic Web. We will put all three to use as we take our next step up the Semantic Web layer cake in a review of the Resource Description Framework (RDF). At the same time, we will be taking the visual RDF/OWL editor, Altova SemanticWorks, for a test drive. Since I will be using this tool for the very first time, you can expect an honest review that is rich with screenshots. If you do not already have the software, you may wish to download the trial version now so you can follow along.

A lot of you emailed me asking where to find more videos, so I'm delivering the goods. I've expanded the previous list from a paltry 17 to a remarkable 302, and I've included podcasts this time! There were so many videos I had to break them up into different categories for easier skimming. There are no duplicates, however I did place some videos into more than one category when I felt it was appropriate. This list is monstrous, enjoy.

Service Ontologies

Published 15 years ago by Aditya Thatte

Ontologies classifying and describing services are called service ontologies. The currently used WSDL interface describes a service by specifying the operation name, inputs required for the service invocation, output of the service and its target address for invocation. Human intervention is required in this loop since the current architecture only addresses the syntactical aspects of Web services and lacks choreography mechanisms.

Update: 302 Semantic Web Videos and Podcasts!

I've compiled a list of videos about the Semantic Web, RDF, and OWL for your viewing pleasure! Most of these videos are short, ranging from about 6 to 10 minutes while others are long (45+ minutes). Included are a few introductions, a few interviews, and a few that get into the gritty details.

Weekend Brain Dump of Ideas

Published 17 years ago by James Simmons

  • Semantic metadata for video and other multimedia?
  • Will a new platform away from the browser have huge success? (ala Joost)
  • How can video games benefit from what we're doing with the Semantic Web?
  • Is Wikipedia the best playground for natural language processors to test their ability?
  • Does the World Wide Web as we know it need to be replaced?
  • Is HTTP inadequate for the future of the Web where streaming and maintaining state are becoming increasingly important?
  • Are we entering another brutal browser war? Maybe this one will be different because we know the importance of compatability
  • Will RDF or RDF/a be adopted by mainstream Web developers to markup semantic metadata?
  • ...Or will something come along that's better suited and easier for beginners to pick-up
  • Are we making any progress as-is towards our goal, or do we need to look for a different approach?
  • Is the best course bottom-up (building the Semantic Web from the ground up by using semantic markup, microformats, RDF, etc) or is it top-down (using natural language processors to read the Web and make sense of it for us).
  • With the freedom to create any RDF vocabulary or any ontology for that matter, will the real power be in mapping my meaning to your meaning?

The Semantic Web is a thing of data purity and interconnectedness the likes of which we have not seen. However, people are selfish. On top of that, people are lazy and fallible. All of these qualities in humans form a road block that we must get past if we hope to create the Semantic Web. We need to both satisfy the selfishness of man and overcome our error-prone nature if we are to reach our goal.

The Curse of Knowledge and the Semantic WebThe Curse of Knowledge: the more you know, the more difficult it is for you to communicate knowledge. When we know something, we can hardly imagine not knowing it. The more we learn about something, the more it becomes even harder for us to think of not knowing it. It is generally difficult for experts (who know much) to explain their expertise to laymen (who know little) because experts have to try hard to imagine the scenario when they were not experts. This is the Curse of Knowledge.

5 Problems of the Semantic Web

Published 17 years ago by James Simmons

I like to consider myself fair and balanced when speaking about most topics. To educate the uneducated and to balance things out a bit I have compiled a list of 5 problems we will likely run into when we reach the Semantic Web. Each problem is a side-effect of advances in technology, rushes to fill new niches, or the previous two plus the desire to make a quick dollar.
