Abstract:
HyperContext is a new model for adaptive hypertext. HyperContext achieves
adaptation of the information and hyper-links through explicit context.
Objects
of information obtain their context from their parent objects and in-links.
When objects of information are accessed, they are interpreted according
to the
appropriate context of the parent object and link pair, prior to being
presented to the user. All objects of information have a profile, a set
of labels which
together comprise a context-free description of the object. An object
interpretation is a subset of the labels in the profile which comprise
a description of the
object relevant to the context in which it exists. Labels become links
when they are associated with objects of information in some context. The
same label
can appear in different interpretations of an object of information,
and in each interpretation the same label can be linked to different objects.
HyperContext is
a three-layer model. The Object layer is an unstructured collection
of object representations. The Structure layer is a hypertextual representation
of
interpretations of the objects in the Object layer. Users interact
with HyperContext through the Presentation layer. Three information retrieval
methods,
which support context-free and context-sensitive search, are also presented.
