There is a contradiction. The dream of the Semantic Web is beautiful, but few people are willing to realize it initiatively. The reason is primarily due to the pitiful nature of the selfishness of mankind; we prefer to enjoy contributions from others rather than contributing to others in the first hand. Some pessimistic ones of us, such as Stephen Downs and Mor Naaman, had even sentenced the Semantic Web to death due to this reason. Others of us, however, also cannot avoid but only try to solve this contradiction, actively and optimistically.

More and more people are starting to discuss the Semantic Web, but few truly understand how it is different from the traditional World Wide Web. Though the Semantic Web will be realized as a layer upon the current Web, some of their basic philosophies are going to be updated significantly. This post tries to list some truth about the Semantic Web that is critical but often overlooked.

Before I started researching the Semantic Web I spent a few years as a hobbyist game developer. In fact, if you'd asked me 4 years ago what I'd be doing today I would have said "working on a game engine." I still enjoy game development and (naturally) playing video games as well. I often wonder how the Semantic Web will affect game development, and how games may take advantage of Semantic Web technologies. I've searched high and low (on Google) and haven't found a single written piece on people's ideas of the Semantic Web and video games so I will describe my own, as well as provide some visuals to give you a clear picture.

The 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.

Yihong Ding (contributing author of this blog) has posted the fourth installment to his thought provocing series A View of Web Evolution. In this installment Yihong states that there exist natural mappings between the stages of web evolution and the stages on human growth. He goes on to describe the life stages of web nodes beginning with Web 1.0 nodes as newborn babies, Web 2.0 nodes as pre-school kids, and Semantic Web nodes as educated children.

The entire series is an engaging read and I suggest to everyone that hasn't already read it to do so!

Semantic Web services follow a life cycle, right from deployment to its invocation.

The life cycle of Semantic Web services comprises different stages like service modeling, service discovery, service definition and service delivery. The life cycle begins with modeling the web service and the service request by the provider and the consumer respectively. Web service descriptions are developed using models like OWL-S, WSMO. Service descriptions are used in the discovery stage on which discovery algorithms, matchmaking techniques are applied. Once a set of service providers are identified for a service requester, service definition takes place to select the concrete service. Finally, the concrete service is delivered to the service requester in the delivery phase.

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.

Once again, the main idea behind the social network comes from a reversal process. We're dealing with an approach focused on the people (user-centric) and not on the applications allowing us to produce various data (text with blogs, pictures on Flickr, videos on YouTube, etc.). Rather than indicate to our contacts the numerous RSS feeds representing our "digital life", we are going to point at a unique address (our OpenID) whereby they will have access to any shared data. Even better, they will be able to add us in their contact list in order to automatically receive our new data (our "lifestreams"). To draw a parallel between an existing tool, adding an RSS feed to an aggregator like Google Reader comes down to adding a contact in our social network. But there is a major difference because this new approach simplifies things a lot while introducing many new fascinating possibilities.
