TimmyHSemantic Sense for the Desktop

A project brings Semantic Web technology to personal documents.
People naturally group information by topic and remember relationships between important things, like a person and the company where she works. But enabling computers to grasp these same concepts has been the subject of long-standing research. Recently, this has focused on the Semantic Web, but a European endeavor called the Nepomuk Project will soon see the effort take new steps onto the PC in the form of a "semantic desktop."
Those working on the project, coordinated by the German Research Center for Artificial Intelligence (DFKI), have been toiling for three years to create software that can spot meaningful connections between the files on a computer. Nepomuk's software is available for several computer platforms and now comes as a standard component of the K Desktop Environment (KDE), a popular graphical interface for the Linux operating system.
The idea of a semantic desktop is not new. The Open Source Applications Foundation and SRI, two nonprofit organizations, have both worked on similar projects. But previous efforts have suffered from the difficulty of generating good semantic information: for semantic software to be useful, semantic information needs to be generated and tagged to files and documents. But without useful applications in the first place, it is hard to persuade users to generate and tag this data themselves.
Nepomuk is distinguished by a more practical vision, says Ansgar Bernardi, deputy head of knowledge management research at DFKI. The software adds a lot of semantic information automatically and encourages users to add more by making annotated data more useful. It also provides an easy way to share tagged information with others.
The software generates semantic information by using "crawlers" to go through a computer and annotate as many files as possible. These crawlers look through a user's address book, for example, and search for files related to the people found in there. Nepomuk can then connect a file sent by a particular person with one related to the company that person works for, making Nepomuk a particularly useful way to search a computer, Bernardi says.
