Figure 7. The basic verbal/visual correspondence <strong>of</strong> ULM<br />

Notice also how <strong>the</strong> latter relationship is expressed in <strong>the</strong> opposite direction: The<br />

statement “car has fuel tank” is transported by <strong>the</strong> instantiation operator (<strong>the</strong> indefinite<br />

article a) into <strong>the</strong> statement “a car has a fuel tank”.<br />

.Conzilla:......................................<br />

A.Human.<strong>Semantic</strong>.<strong>Web</strong>.Browser<br />

During <strong>the</strong> past seven years, we have developed a prototype <strong>of</strong> a concept browser<br />

(Naeve, 2001a), called Conzilla (Palmér & Naeve, 2005; Conzilla, n.d.). Since<br />

Conzilla is designed with a clear object-oriented structure that separates <strong>the</strong> underlying<br />

logic from <strong>the</strong> presentation and style graphics, it can easily be adapted<br />

to different presentational styles and cognitive pr<strong>of</strong>iles. 18 Several Conzilla-based<br />

knowledge manifolds have been constructed (i.e., within <strong>the</strong> fields <strong>of</strong> ma<strong>the</strong>matics,<br />

IT standardization, and interoperability among different systems for e-commerce)<br />

(ECIMF, n.d.).<br />

A concept browser is a powerful tool with a multitude <strong>of</strong> potential applications,<br />

and Conzilla is attracting increased attention both on <strong>the</strong> national and international<br />

levels. Within <strong>the</strong> framework <strong>of</strong> <strong>the</strong> human <strong>Semantic</strong> <strong>Web</strong>, we are aiming to develop<br />

Conzilla into a generic information management tool by participating in collaborative<br />

projects that will expand <strong>the</strong> capabilities <strong>of</strong> <strong>the</strong> program within <strong>the</strong> rapidly<br />

converging areas <strong>of</strong> learning and knowledge management, focusing on <strong>the</strong> domains<br />

<strong>of</strong> e-learning, e-commerce, and e-administration. 19<br />

In February 2005, we released Conzilla2, a human <strong>Semantic</strong> <strong>Web</strong> browser, or a<br />

conceptual interface to <strong>the</strong> (machine) <strong>Semantic</strong> <strong>Web</strong>. Its main requirements are as<br />
