Title: Knowledge tuples never die, they just fade away
Authors: Dr. Lyndon Nixon, Dr. Robert Tolksdorf, Dr. Ronaldo Menezes, Dr. Alan Wood
A new application of tuple-space-based coordination systems
is in knowledge communication and representation.
This knowledge is being published on the Web (the socalled
“Semantic Web”) and could be concurrently accessed
and used by large numbers of agents distributed
across the world. Present coordination models assume
that the tuples contain plain data, but when knowledge
is being coordinated some aspects of coordination systems
such as Linda must be revised. In this paper, we
focus on the issues of tuple-space views and the ability
of agents to perform destructive retrieval of information
from the tuple spaces. Knowledge is not something that
is universally shared, rather different groups share different
views of the world. It is also something that does not
cease suddenly to exist, rather it tends to be forgotten as
new knowledge replaces it. Hence we introduce the concepts
of scoping and fading and describe how this can be
applied to support knowledge-based multi-agent coordination
on the emerging Semantic Web.
