Title:
SILK: Higher Level Rules with Defaults and Semantic Scalability
Abstract:
We overview the technical approach and motivations of the SILK system for
semantic rules and ontologies, that radically extends the knowledge
representation (KR) power of currently commercially important business rule
systems, including not only Prologs but also production rules and
event-condition-action rules, database systems, and semantic web.

Title:
Integrating Logic Programming and Production Systems in Abductive Logic Programming Agents
Abstract:
In this talk we argue the case for integrating the distinctive functionalities
of logic programs and production systems within an abductive logic programming
agent framework. In this framework, logic programs function as an agent's beliefs
and production rules function as the agent’s goals. The semantics and proof
procedures are based on abductive logic programming, in which logic programs
are integrated with integrity constraints that behave like production rules.
Similarly to production systems, the proof procedure is an operational semantics,
which manipulates the current state of a database, which is modified by actions
implemented by destructive assignment. The semantics can be viewed as generating
a model, based on the sequence of database states and logic program, which
makes the production rules true.
