Tanel Tammet
1995 Proceedings of the fourth international conference on Information and knowledge management - CIKM '95  
Severaf decidable classes usable as new knowledge representation languages are presented, cent aining some well-known ones, like the base language ALC of KL-ONE type systems, along with the resolution-based  ...  The paper presents some methods for developing such languages based on decidable classes.  ...  as inference engines for predicate logic transla- tions of KL-ONE type languages.  ...

Hybrid Systems for Knowledge Representation in Artificial Intelligence

Rajeswari P.V, Dr. T.
2012 International Journal of Advanced Research in Artificial Intelligence (IJARAI)  
There are few knowledge representation (KR) techniques available for efficiently representing knowledge. However, with the increase in complexity, better methods are needed.  ...  In an effort to construct an intelligent computer system, a primary consideration is to represent large amounts of knowledge in a way that allows effective use and efficiently organizing information to  ...  The difficulties in representing assertional knowledge using KL-ONE gives the idea of the integration of a theoremprover and a KL-ONE-like language into a hybrid system.  ...

A resolution-based proof method for temporal logics of knowledge and belief [chapter]

Michael Fisher, Michael Wooldridge, Clare Dixon
1996 Lecture Notes in Computer Science  
Secondly, a family of resolution rules are used, to deal with the interactions between the various operators of the logics.  ...  The logic BLn is somewhat similar: it is a temporal logic that contains connectives for representing the beliefs of agents. The proof methods we present for these logics involve two key steps.  ...  Thus, in extending the temporal resolution method of [7] to BL n and KL n , we need only consider the additional step resolution rules and simplification rules for handling formulae containing modal  ...

Simple supervised document geolocation with geodesic grids

Benjamin Wing, Jason Baldridge
2011 Annual Meeting of the Association for Computational Linguistics  
We describe several simple supervised methods for document geolocation using only the document's raw text as evidence.  ...  All of our methods predict locations in the context of geodesic grids of varying degrees of resolution. We evaluate the methods on geotagged Wikipedia articles and Twitter feeds.  ...  This paper benefited from reviewer comments and from discussion in the Natural Language Learning reading group at UT Austin, with particular thanks to Matt Lease.  ...

Guest editors' foreword

Hans Ulrich Simon, Etsuji Tomita
2007 Theoretical Computer Science  
As for learning from examples, a further decision is whether we impose statistical assumptions on the sequence of examples or not.  ...  The papers in this special issue offer a broad view on the current research in the field including studies on several learning models (such as Bayesian and statistical models, PAC-learning, query-learning  ...  By passing from KL-divergence to the variation distance (still useful for pattern classification tasks), Palmer and Goldberg are able to considerably simplify the proof for PAC-learnability and to remove  ...

AN ESSENTIAL HYBRID REASONING SYSTEM: KNOWLEDGE AND SYMBOL LEVEL ACCOUNTS OF KRYPTON [chapter]

Ronald J. Brachman, Victoria Pigman Gilbert, Hector J. Levesque
1989 Readings in Artificial Intelligence and Databases  
KRYPTON is unique in that it combines in a completely integrated fashion a frame-based description language and a first-order resolution theorem-prover.  ...  experimental prototype that competently handles both terminological and assertional knowledge; these two kinds of information are tightly linked by having sentences in an assertional component be formed using  ...  On the other hand, KL-TWO uses a much more tractable (propositional) ABox.  ...

Resolution for temporal logics of knowledge

C Dixon
1998 Journal of Logic and Computation  
A resolution based proof system for a temporal logic of knowledge is presented and shown to be correct. Such logics are useful for proving properties of distributed and multi-agent systems.  ...  An extension of the basic system to the multimodal case is given and illustrated using the 'muddy children problem'.  ...  In this paper, we extend the proof method for purely temporal logics described in [17] to deal with KL n by using modal resolution rules similar to those devised by Mints [29] .  ...

Towards the Integration of Functions, Relations and Types in an AI Programming Language [chapter]

Rolf Backofen, Lutz Euler, Günther Görz
1990 Informatik-Fachberichte  
This language integrates the functional and the logic-oriented programming style and feature types supporting inheritance.  ...  This combination yields a language particularly suited to knowledge representation , especially for application in computational linguistics.  ...  They can be extended up to feature terms without losing the possibility of using unification and a resolution-based theoremprover on them. This is described in full detail in [5] .  ...

Theorem proving for classical logic with partial functions by reduction to Kleene logic

Hans de Nivelle
2014 Journal of Logic and Computation  
For proof search we use a three-valued adaptation of geometric resolution. We prove that the calculus is sound and complete.  ...  In this paper, we develop a theorem proving strategy for Partial Classical Logic (PCL). Proof search takes place in Kleene Logic.  ...  If one would want to express the precondition of (−)in the left column, one would have to extend the language with a formalism for expressing the precondition.  ...

Linear usage of state

Rasmus Møgelberg, Sam Staton, Bartek Klin
2014 Logical Methods in Computer Science  
We do this by studying a fully-complete state-passing translation from an impure call-by-value language to a new linear type theory: the enriched call-by-value calculus.  ...  The results are not specific to store, but can be applied to any computational effect expressible using algebraic operations, even to effects that are not usually thought of as stateful.  ...  In Section 4 we provide a linear-use state passing translation from the source language to the target language The translation on types takes a type τ of the source language to a value type τ S of the  ...

María del Mar Gallardo, Christophe Joubert, Pedro Merino
2006 Second International Symposium on Leveraging Applications of Formal Methods, Verification and Validation (isola 2006)  
In particular, one powerful method to implement abstract matching is to fill the state vector with a minimal amount of relevant variables for each program point.  ...  The well-known problem of state space explosion in model checking is even more critical when applying this technique to programming languages, mainly due to the presence of complex data structures.  ...  ANNOTATOR) consists of two parts: a front-end, responsible for encoding the verification of the L 1 µ formula (resp. the static analysis type) on LTS 1 as a BES (resp.
