Contexts for Concepts: Information Modeling for Semantic Interoperability

by Paul Oude Luttighuis , Roel Stap , Dick Quartel
"... Abstract. Conceptual information modeling is a well-established practice, aimed at preparing the implementation of information systems, the specification of electronic message formats, and the design of information processes. Today's ever more connected world however poses new challenges for c ..."

;horizontal' need. As an alternative, a conceptual information modeling approach is described that is simultaneously unconventional as well as interoperable with existing approaches. The key to this approach is conceptual context-awareness. It is based on ideas from the Metapattern work

Semantic matching of web services capabilities

by Massimo Paolucci, Takahiro Kawamura, Terry R. Payne, Katia Sycara , 2002
"... Abstract. The Web is moving from being a collection of pages toward a collection of services that interoperate through the Internet. The first step toward this interoperation is the location of other services that can help toward the solution of a problem. In this paper we claim that location of web ..."

propose a solution based on DAML-S, a DAML-based language for service description, and we show how service capabilities are presented in the Profile section of a DAML-S description and how a semantic match between advertisements and requests is performed. 1 Introduction Web services provide a new model

Semantic similarity based on corpus statistics and lexical taxonomy

by Jay J. Jiang, David W. Conrath - Proc of 10th International Conference on Research in Computational Linguistics, ROCLING’97 , 1997
"... This paper presents a new approach for measuring semantic similarity/distance between words and concepts. It combines a lexical taxonomy structure with corpus statistical information so that the semantic distance between nodes in the semantic space constructed by the taxonomy can be better quantifie ..."

A SOUND TYPE SYSTEM FOR SECURE FLOW ANALYSIS

by Dennis Volpano, Geoffrey Smith, Cynthia Irvine , 1996
"... Ensuring secure information ow within programs in the context of multiple sensitivity levels has been widely studied. Especially noteworthy is Denning's work in secure ow analysis and the lattice model [6][7]. Until now, however, the soundness of Denning's analysis has not been established ..."

Classical negation in logic programs and disjunctive databases

by Michael Gelfond, Vladimir Lifschitz - New Generation Computing , 1991
"... An important limitation of traditional logic programming as a knowledge representation tool, in comparison with classical logic, is that logic programming does not allow us to deal directly with incomplete information. In order to overcome this limitation, we extend the class of general logic progra ..."

programs by including classical negation, in addition to negation-as-failure. The semantics of such extended programs is based on the method of stable models. The concept of a disjunctive database can be extended in a similar way. We show that some facts of commonsense knowledge can be represented by logic

Non-Malleable Cryptography

by Danny Dolev, Cynthia Dwork, Moni Naor - SIAM Journal on Computing , 2000
"... The notion of non-malleable cryptography, an extension of semantically secure cryptography, is defined. Informally, in the context of encryption the additional requirement is that given the ciphertext it is impossible to generate a different ciphertext so that the respective plaintexts are related. ..."

TextonBoost: Joint Appearance, Shape and Context Modeling for Multi-Class Object . . .

by J. Shotton, J. Winn, C. Rother, A. Criminisi - IN ECCV , 2006
"... This paper proposes a new approach to learning a discriminative model of object classes, incorporating appearance, shape and context information efficiently. The learned model is used for automatic visual recognition and semantic segmentation of photographs. Our discriminative model exploits nov ..."

A Neural Probabilistic Language Model

by Yoshua Bengio, Réjean Ducharme, Pascal Vincent, Christian Jauvin - JOURNAL OF MACHINE LEARNING RESEARCH , 2003
"... A goal of statistical language modeling is to learn the joint probability function of sequences of words in a language. This is intrinsically difficult because of the curse of dimensionality: a word sequence on which the model will be tested is likely to be different from all the word sequences seen ..."

The model learns simultaneously (1) a distributed representation for each word along with (2) the probability function for word sequences, expressed in terms of these representations. Generalization

Model Selection and Model Averaging in Phylogenetics: Advantages of Akaike Information Criterion and Bayesian Approaches Over Likelihood Ratio Tests

by David Posada, Thomas R. Buckley , 2004
"... Model selection is a topic of special relevance in molecular phylogenetics that affects many, if not all, stages of phylogenetic inference. Here we discuss some fundamental concepts and techniques of model selection in the context of phylogenetics. We start by reviewing different aspects of the sel ..."

Using semantic values to facilitate interoperability among heterogeneous information systems

by Edward Sciore - In ACM Transactions on Database Systems , 1994
"... Large organizations need to exchange information among many separately developed systems. In order for this exchange to be useful, the individual systems must agree on the meaning of their exchanged data. That is, the organization must ensure semantzc mteroperabdity. This paper provides a theory of ..."

of semantzc values as a unit of exchange that facilitates semantic interoperability between heterogeneous information systems. We show how semantic values can either be stored explicitly or be defined by environments. A system architecture is presented that allows autonomous components to share semantic
