We address the goal of making Delegation Logic (DL) into a practically implementable and tractable trustmanagement system. DL [22] is a logic-based knowledge representation (i.e.,...
In this paper we describe an approach to constraint based syntactic theories in terms of finite tree automata. The solutions to constraints expressed in weak monadic second order ...

This paper presents proposals of certain extensions to the XTT knowledge representation model, a method of tabular specification for rule-based systems. The extensions concern
