These structures can be predefined by the programmer, or be created dynamically by extracting details from Web pages. 4. 1 IS A Hierarchy Links The IS A hierarchy about AI, logic programming, and agents described here is loosely based on the Canto hypertext data model [11]. Its overall structure is shown in Figure 3. isa 2 represents an IS A relation between concepts in the form of isa(Subconcept, Concept) links: isa(logicprogramming, ai) isa(agents, ai) isa(agenttheories, agents) isa(agentarchitectures, agents) isa(agentlanguages, agents) isa(mobilecode, ....

....a hypertext system. The hierarchical structure is maintained through a system of implicit links between concept nodes. In this paper we present the Canto data model, and describe how Canto reduces user disorientation. The use of this schema minimizes the user s feeling of being lost within thedata[8]. We first describe the important features of the Canto hypertext data model. In the sections that follow, we present a formal specification of Canto s functionality, and we discuss the schema definition language that a hypertext system designer uses to establish a hypertext schema. We then ....
....links may be either implicit or explicit. Implicit links are derived from the structure and order of the nodes. Implicit links connect concept nodes to other concept nodes, or to information nodes. Explicit links may connect any two nodes, and are used to represent non hierarchical relationships [8]. The general form of a Canto hyperdocument is shown in Figure 1. A specific example is shown in Figure 4.
