Dynamic Logic

by David Harel, Dexter Kozen, Jerzy Tiuryn - Handbook of Philosophical Logic , 1984
"... ed to be true under the valuation u iff there exists an a 2 N such that the formula x = y is true under the valuation u[x=a], where u[x=a] agrees with u everywhere except x, on which it takes the value a. This definition involves a metalogical operation that produces u[x=a] from u for all possibl ..."

Case-based reasoning; Foundational issues, methodological variations, and system approaches

by Agnar Aamodt, Enric Plaza - AI COMMUNICATIONS , 1994
"... Case-based reasoning is a recent approach to problem solving and learning that has got a lot of attention over the last few years. Originating in the US, the basic idea and underlying theories have spread to other continents, and we are now within a period of highly active research in case-based rea ..."

Choices, values and frames.

by Daniel Kahneman - American Psychologist, , 1984
"... Making decisions is like speaking prose-people do it all the time, knowingly or unknowingly. It is hardly surprising, then, that the topic of decision making is shared by many disciplines, from mathematics and statistics, through economics and political science, to sociology and psychology. The stu ..."
Abstract - Cited by 684 (9 self) - Add to MetaCart
. The study of decisions addresses both normative and descriptive questions. The normative analysis is concerned with the nature of rationality and the logic of decision making. The descriptive analysis, in contrast, is concerned with people's beliefs and preferences as they are, not as they should be

System Description: Twelf --- A Meta-Logical Framework for Deductive Systems

by Frank Pfenning, Carsten Schurmann - Proceedings of the 16th International Conference on Automated Deduction (CADE-16 , 1999
"... . Twelf is a meta-logical framework for the specification, implementation, and meta-theory of deductive systems from the theory of programming languages and logics. It relies on the LF type theory and the judgments-as-types methodology for specification [HHP93], a constraint logic programming interp ..."

interpreter for implementation [Pfe91], and the meta-logic M2 for reasoning about object languages encoded in LF [SP98]. It is a significant extension and complete reimplementation of the Elf system [Pfe94]. Twelf is written in Standard ML and runs under SML of New Jersey and MLWorks on Unix and Window

Simulation, verification, automated composition of web services

by Srini Narayanan, Sheila A. Mcilraith - In WWW , 2002
"... Web services-- Web-accessible programs and devices – are a key application area for the Semantic Web. With the proliferation of Web services and the evolution towards the Semantic Web comes the opportunity to automate various Web services tasks. Our objective is to enable markup and automated reason ..."
Abstract - Cited by 391 (7 self) - Add to MetaCart
. With the semantics in hand, we encode our service descriptions in a Petri Net formalism and provide decision procedures for Web service simulation, verification and composition. We also provide an analysis of the complexity of these tasks under different restrictions to the DAML-S composite services we can describe

Tableau Algorithms for Description Logics

by Franz Baader, Ulrike Sattler - STUDIA LOGICA , 2000
"... Description logics are a family of knowledge representation formalisms that are descended from semantic networks and frames via the system Kl-one. During the last decade, it has been shown that the important reasoning problems (like subsumption and satisfiability) in a great variety of descriptio ..."
Abstract - Cited by 260 (26 self) - Add to MetaCart
. Nevertheless, due to different underlying intuitions and applications, most description logics differ significantly from run-of-the-mill modal and program logics. Consequently, the research on tableau algorithms in description logics led to new techniques and results, which are, however, also of interest

Specification Matching of Software Components

by Amy Moormann Zaremski, Jeannette M. Wing - ACM Transactions on Software Engineering and Methodology , 1996
"... Specification matching is a way to compare two software components based on descriptions of the components' behaviors. In the context of software reuse and library retrieval, it can help determine whether one component can be substituted for another or how one can be modified to fit the requ ..."

A Novel Combination of Answer Set Programming with Description Logics for the Semantic Web

by Thomas Lukasiewicz - IN PROC. KR-2004 , 2004
"... Abstract. We present a novel combination of disjunctive logic programs under the answer set semantics with description logics for the Semantic Web. The combination is based on a well-balanced interface between disjunctive logic programs and description logics, which guarantees the decidability of th ..."

The even more irresistible SROIQ

by Ian Horrocks, Oliver Kutz, Ulrike Sattler - In KR , 2006
"... We describe an extension of the description logic underlying OWL-DL, SHOIN, with a number of expressive means that we believe will make it more useful in practise. Roughly speaking, we extend SHOIN with all expressive means that were suggested to us by ontology developers as useful additions to OWL- ..."

Semantical considerations on Floyd-Hoare Logic

by Vaughan R. Pratt , 1976
"... This paper deals with logics of programs. The objective is to formalize a notion of program description, and to give both plausible (semantic) and effective (syntactic) criteria for the notion of truth of a description. A novel feature of this treatment is the development of the mathematics underlyi ..."
