We present the Orlog deductive object oriented database system prototype The implementation of the system relies on the idea of reducing inheritance to deduction and giving a relational interpretation to every Orlog database The prototype is a user transparent front end for coral deductive database system and provides a full edgedprogrammingenvironment in Orlog

The ROCK & ROLL database system cleanly integrates deductive and object-oriented capabilities by deening an imperative programming language , ROCK, and a declarative, deductive language, ROLL, over a common object-oriented (OO) data model. Existing techniques for evaluation and optimization of deductive languages fail to address key requirements imposed by ROLL such as: strict typing; placement...

This paper gives a brief description of the KeY system, a tool written as part of the ongoing KeY project, which is aimed at bridging the gap between (a) OO software engineering methods and tools and (b) deductive verification. The KeY system consists of a commercial CASE tool enhanced with functionality for formal specification and deductive verification.

In this paper we introduce a deductive planning system currently being develop ed as the kernel of an intelligent help system. It consists of a deductive planner and a plan reuse component and with that provides planning from first as well as planning from second principles . Both components rely upon an interval-based temporal logic. The deductive formalisms realizing plan formation from forma...

Over the course of the past decade, contradictory claims have been made regarding the neural bases of deductive reasoning. Researchers have been puzzled by apparent inconsistencies in the literature. Some have even questioned the effectiveness of the methodology used to study the neural bases of deductive reasoning. However, the idea that neuroimaging findings are inconsistent is not based on a...

The aim of this paper is the partial axiomatization for firstorder predicate calculus formal system based on first-level universal AND operator. By introducing the universal quantifier and existential quantifier, a predicate calculus formal deductive system ∀ULh∈(0,1] based on 1-level universal AND operator according to propositional calculus formal deductive system ULh∈(0,1] of universal logic...

This is an overview of the knowledge base management system called Kappa, one of the research and development activities performed at ICOT on databases and knowledge bases. The underlying data model is a nested relational model, and some complex data models are constructed and under consideration on the model. Deductive databases are constructed as one of knowledge base mechanisms and further e...

In this paper, we will report on the experience of building a successful industrial application using the LDL++ deductive database as part of the technology transfer process to our sponsor company, Eastman Chemical Company. We will describe the nature of the problems faced by Eastman Chemical Company and show how the LDL++ deductive database technology helps to build an Intelligent Information ...

A pair of deductive systems (S,S’) is Leibniz-linked when S’ is an extension of S and on every algebra there is a map sending each filter of S to a filter of S’ with the same Leibniz congruence. We study this generalization to arbitrary deductive systems of the notion of the strong version of a protoalgebraic deductive system, studied in earlier papers, and of some results recently found for pa...
