"Creating a web that can be interpreted by machines"


The idea was articulated in an article in Scientific American five years ago by web creator Tim Berners-Lee, Professor Jim Hendler of the University of Maryland, and Professor Ora Lassila of phone giant Nokia.

It was their idea to try to start to make sense of the tangle of data on the World Wide Web.

Until now, almost all of the information on webpages is produced by humans for humans.

Although a computer is good for viewing the information on webpages and crunching some of the numbers contained in databases, it is no good for extracting the meaning of words and numbers on websites.


Efforts to build this next wave have been going on since the Scientific American article was published.

But before the general public will start to notice the benefits, researchers must make sure that software is developed and, importantly, that the data is available and classified correctly.

According to semantic visionary Jim Hendler some of those pieces are starting to fall into place quite quickly.

There is now even a test version of a semantic search engine called "Swoogle" at the University of Maryland.

But just as getting a coherent definition of the semantic web is tricky, finding out when it will arrive is harder still.

However, one thing that all the researchers at the conference agree upon is that when it does appear, anything that has gone before on the web will seem mundane in comparison.

"You ain't see nothing yet," promised Professor Hendler.
