Order-Sorted Reasoning in the Situation Calculus
We propose a theory for reasoning about actions based on order-sorted predicate logic where one can consider an elab orate taxonomy of objects. We are interested in the projection problem: whether aExpand
Report RR-90-10 Concept Logics
Concept languages (as used in BACK, KL-ONE, KRYPTON, LOOM) are employed as knowledge representation formalisms in Artificial Intelligence. Their main purpose is to represent the generic concepts andExpand
New Language Constructs and Inferences for the Knowledge Base Paradigm: A Business and Multi-agent Perspective ; Taaluitbreidingen en nieuwe inferenties voor het kennisbank paradigma vanuit een Business en Multi-Agent perspectief
TLDR
This text uses an implementation of a KB system: the IDP system with corresponding language FO(·) to model challenging and interesting applications and proves the hypothesis that this approach has many advantages over standard declarative paradigms. Expand
Existential rigidity and many modalities in order-sorted logic
TLDR
In this study, a new labeled tableau calculus is presented to check the (un)satisfiability and validity of sorted modal formulas to extend order-sorted logic by introducing existential rigidity and many modalities. Expand
Finite domain and symbolic inference methods for extensions of first-order logic
TLDR
This dissertation studies the tasks of constraint propagation, grounding, model revision, and debugging for FO(·), a rich extension of classical logic with, amongst others, inductive definitions and aggregates. Expand
The Typed Situation Calculus 2 Introduction
We propose a theory for reasoning about actions based on order-so rt d predicate logic where one can consider an elaborate taxonomy of objects . We are interested in the projection problem: whether aExpand
Distributed reasoning with ontologies and rules in order-sorted logic programming
TLDR
A query-answering system that combines order-sorted linear resolution and rigid-property resolution as top-down algorithms to enable the reasoning to be effective and decidable. Expand
Translating a Dependently-Typed Logic to First-Order Logic
TLDR
A translation from DFOL to FOL formalized as an institution comorphism and show that it admits the model expansion property and implies the soundness of borrowing, which enables to reason about entailment in DFOL by using automated tools for FOL. Expand
A Unified Approach to Theory Reasoning
TLDR
A classification for the various approaches for theory reasoning which is based on the syntactic concepts of literal level — term level — variable level is defined and current ways of equality handling are described. Expand
Combining Order-Sorted Logic Programming with Formal Ontology 1
In formal ontology, entity types and relationships are philosophically defined, and the properties of objects are classified on the basis of sortality, rigidity, and identity (called propertyExpand

TLDR
This paper presents a new method of proof for the first-order functional calculus which requires less formal development of the system from the axioms and suggests a new approach to the problem of completeness for functional calculi of higher order. Expand
