A Little Semantics Goes a Long Way: The Night Watchman and Other Stories
Lawrence A. Birnbaum
The Institute for the Learning Sciences, Northwestern University
The intelligent, interactive technologies of the future -- personalized
information access systems, learning-by-doing environments, and things not yet
conceived -- must be semantically competent. That is, they must be built in
accordance with, or have embedded in them, the causal models that people have
of their goals, tasks, and environments.
Building these new interactive technologies will require semantic models and
toolkits in addition to the computationally-oriented toolkits available today.
The problem in developing such toolkits has been the apparent idiosyncrasy and
variability of semantic content across domains. In this talk I will argue that
there exist high-leverage semantic models of broad applicability that can form
the basis of a wide variety of semantically competent technologies operating in
a wide variety of settings. I will present a number of examples to show how, in
many cases, just a little of this sort of semantics is needed to drive an
interesting application.
Refreshments will be served immediately before the talk at 3:30pm.
Hosted by Gerhard Fischer.
