A Unified Hierarchy for Functional Dependencies, Conditional Functional Dependencies and Association Rules [chapter]

Raoul Medina, Lhouari Nourine
2009 Lecture Notes in Computer Science  
Conditional Functional Dependencies (CFDs) are Functional Dependencies (FDs) that hold on a fragment relation of the original relation.  ...  In this paper, we show that all those dependencies are indeed structurally the same and could be unified into a single hierarchy of dependencies.  ...  We cite (among others): Association Rules (AR) [1] which are dependencies holding on particular values of attributes, and Approximate Functional Dependencies (AFD) [15] which are FDs which almost hold  ...

A Satisfactory-Oriented Approach to Multiexpert Decision-Making With Linguistic Assessments

V.-N. Huynh, Y. Nakamori
2005 IEEE Transactions on Systems Man and Cybernetics Part B (Cybernetics)  
under the same evaluation scheme, we propose a linguistic choice function to establish a rank ordering among the alternatives.  ...  preferences to obtain a collective preference value for each alternative; and an exploitation phase that orders the collective preferences according to a given criterion, to select the best alternative  ...  This approach consists of two elements: 1) the primary fuzzy sets designed as associated semantics of the primary linguistic terms and 2) a semantic rule for generating fuzzy sets semantically associated  ...

Typed Linear Chain Conditional Random Fields and Their Application to Intrusion Detection [chapter]

Carsten Elfers, Mirko Horstmann, Karsten Sohr, Otthein Herzog
2010 Lecture Notes in Computer Science  
Intrusion detection in computer networks faces the problem of a large number of both false alarms and unrecognized attacks.  ...  In this paper we present an inference process with linear chain conditional random fields that aims to solve this problem by using domain knowledge about the alerts of different intrusion sensors represented  ...  Overall, typed linear chain conditional random fields are a promising step in the direction of using complex domain knowledge to improve reasoning over time with only a few reference data.  ...

Representation of roles in biomedical ontologies: a case study in functional genomics

Anita Burgun, Olivier Bodenreider, Franck Le Duff, Fouzia Moussouni, Olivier Loreal
2002 Proceedings. AMIA Symposium  
Functional aspects are represented in both GO and the UMLS. However, the granularity may not be appropriate. Advantages and limits of functional categories and associative relations are discussed.  ...  The objective of this study is to investigate representation of roles as functional categories or associative relations.  ...  a TYPE in order to satisfy identity condition, (2) no mutual disjointedness is expected for ROLES, since an entity can have several roles, (3) design of hierarchies made of both TYPES and ROLES must follow  ...

Inheritance hierarchies: Semantics and unification

Gert Smolka, Hassan Ait-Kaci
1989 Journal of symbolic computation  
We specify a unitary unification algorithm by a set of simplification rules and prove its soundness and completeness with respect to the model-theoretic semantics. t This paper is a revised version of  ...  Inheritance hierarchies are introduced as a means of representing taxonomically organized data.  ...  We are grateful to the members cf the Unification Group at Kaiserslautern for many discussions on the topic of this paper.  ...

Bayesian Games with Intentions

Adam Bjorndahl, Joseph Y. Halpern, Rafael Pass
2016 Electronic Proceedings in Theoretical Computer Science  
However, by introducing a fundamental distinction between intended and actual strategies, we remove this limitation.  ...  We define Bayesian games with intentions, generalizing both Bayesian games and psychological games, and prove that Nash equilibria in psychological games correspond to a special class of equilibria as  ...  Acknowledgements We are indebted to Aviad Heifetz for asking the question that first prompted us to explore the notion of extending Bayesian games to capture belief-dependent preferences.  ...
