2000 Proceedings of the nineteenth ACM SIGMOD-SIGACT-SIGART symposium on Principles of database systems - PODS '00  
InD measures suggest many v aluable applications in areas such as data mining. information dependency, e n tropy, functional dependency, Armstrong's Axioms, Multivalued dependency of M is HM = Hp1; : :  ...  For two sets of attributes X and Y , an information dependency measure InD measure characterizes the uncertainty remaining about the values for the set Y when the values for the set X are known.  ...  Information Dependency Measure. The information dependency measure InD measure of Y given Xis HX!  ...

Tracking Dependent Information Flows

Zeineb Zhioua, Yves Roudier, Rabéa Ameur Boulifa, Takoua Kechiche, Stuart Short
2017 Proceedings of the 3rd International Conference on Information Systems Security and Privacy  
We formally specify security guidelines that involve dependent information flows as a basis to lead formal verification through model checking, and provide precise feedback to the developer.  ...  MOTIVATION Information Flow Analysis Different security mechanisms, such as access control and encryption allow to protect sensitive data, but  ...  This requires security expertise to specify the dependent information flows.  ...

Information dependent games

1988 Economics Letters  
Two by-products are the introduction of information-dependent games, and a formal treatment of the framework of game theoretic axioms.  ...  . , V, ) ) be an informationally-consistent play of the information-dependent game G with respect to &'. If CK E&', then V, = V, = . , , = V,. Proof.  ...  Then there exists a full information-dependent game which has no informationally-consistent play. Proof. Consider the surprise test example (2.5 above).  ...

Dependent Information Flow Types

Luísa Lourenço, Luís Caires
2015 Proceedings of the 42nd Annual ACM SIGPLAN-SIGACT Symposium on Principles of Programming Languages - POPL '15  
In this paper, we develop a novel notion of dependent information flow types.  ...  Dependent information flow types fit within the standard framework of dependent type theory, but, unlike usual dependent types, crucially allow the security level of a type, rather than just the structural  ...  Dependent Information Flow Types In this section, we motivate dependent (function and sum) information flow types by means of several examples, providing an informal overview of the approach developed  ...

Dependability of E-Information Sources [chapter]

Jan Capek
2010 Engineering the Future  
The traditional meaning of Contexts Individuals Information Means Dependability of e-information sources 379 reliability measures does not reflect the real dependability of systems.  ...  Dependability of e-information sources with data carrying information and/or knowledge certainly play a special role here.  ...

Multivariate Dependence beyond Shannon Information

Ryan James, James Crutchfield
2017 Entropy  
We extend this observation to demonstrate that this is true of all such Shannon information measures when used to analyze multivariate dependencies.  ...  Rather, the vast majority of its informational measures are simply inadequate for determining the meaningful dependency structure within joint probability distributions.  ...  We next need a generalization of the "giant bit" [63] which we call dyadic camouflage-to mix with the parity, informationally "canceling out" the higher-order mutual informations even though dependencies  ...

Domain-dependent information gathering agent

Aleksander Pivk, Matjaz Gams
2002 Expert systems with applications  
We present a domain-dependent agent for information gathering. It can visit an arbitrary domain-related site by observing a user perform the first query.  ...  A universal agent should be capable of gathering information from arbitrary heterogeneous sites and offer intelligent information services on its own based on information so gathered.  ...  Acknowledgments Financial support was provided by an international project INCO-Copernicus 960154, Cooperative Research in Information Infrastructure, CRII, by the Ministry of education, science and sports  ...

Information-constrained state-dependent pricing

Michael Woodford
2009 Journal of Monetary Economics  
This results in a one-parameter family of models, indexed by the cost of information, which nests both the standard state-dependent pricing model and the Calvo model of price adjustment as limiting cases  ...  When the model is calibrated to match the frequency and size distribution of price changes observed in microeconomic data sets, prices are found to be much less flexible than in a full-information state-dependent  ...  , but not time-dependent, just as in full-information menu-cost models.  ...

Phase-dependent which-way information

U. Schilling, J. von Zanthier
2012 Physics Letters A  
We introduce a new observable for reading out a which-way detector in a Young-type interferometer whose eigenstates either contain full which-way information or none at all.  ...  We calculate the which-way knowledge K that can be retrieved from this observable and find that K depends on the phase difference \delta that the interfering object accumulates on its way from either slit  ...  In order to have a measure which has a value of 0 (1) for no (full) WW information, one can introduce the knowledge K about the path [19] which we will write as K W to highlight its dependence on the  ...

Versions for Context Dependent Information Services [chapter]

Moira C. Norrie, Alexios Palinginis
2003 Lecture Notes in Computer Science  
Context dependent information delivery is an important requirement of cooperative information systems supporting global and mobile access.  ...  These systems must be able to adapt the content, structure and presentation of information according to various factors such as the user, the access device and the task at hand.  ...  We start in Section 2 with a discussion of context-dependent information delivery and introduce an example used throughout the paper.  ...

2004 Proceedings of the 27th annual international conference on Research and development in information retrieval - SIGIR '04  
This paper presents a new dependence language modeling approach to information retrieval.  ...  We integrate the linkage of a query as a hidden variable, which expresses the term dependencies within the query as an acyclic, planar, undirected graph.  ...  term dependencies on information retrieval.  ...
