An Algebra for Semantic Construction in Constraint-based Grammars
We develop a framework for formalizing semantic construction within grammars expressed in typed feature structure logics, including HPSG. The approach provides an alternative to t...

Optimization of Systems of Algebraic Equations for Evaluating Datalog Queries
A Datalog program can be translated into a system of fixpoint equations of relational algebra; this paper studies how such a system can be solved and optimized for a particular qu...
