A New Penta-valued Logic Based Knowledge Representation
نویسنده
چکیده
In this paper a knowledge representation model are proposed, FP5, which combine the ideas from fuzzy sets and penta-valued logic. FP5 represents imprecise properties whose accomplished degree is undefined, contradictory or indeterminate for some objects. Basic operations of conjunction, disjunction and negation are introduced. Relations to other representation models like fuzzy sets, intuitionistic, paraconsistent and bipolar fuzzy sets are discussed.

Similarity, Cardinality and Entropy for Bipolar Fuzzy Set in the Framework of Penta-valued Representation
In this paper one presents new similarity, cardinality and entropy measures for bipolar fuzzy set and for its particular forms like intuitionistic, paraconsistent and fuzzy set. All these are constructed in the framework of multi-valued representations and are based on a penta-valued logic that uses the following logical values: true, false, unknown, contradictory and ambiguous. Also a new dist...
متن کاملPenta and Hexa Valued Representation of Neutrosophic Information
Starting from the primary representation of neutrosophic information, namely the degree of truth, degree of indeterminacy and degree of falsity, we define a nuanced representation in a penta valued fuzzy space, described by the index of truth, index of falsity, index of ignorance, index of contradiction and index of hesitation. Also, it was constructed an associated penta valued logic and then ...
متن کاملA New Algorithm for Optimization of Fuzzy Decision Tree in Data Mining
Decision-tree algorithms provide one of the most popular methodologies for symbolic knowledge acquisition. The resulting knowledge, a symbolic decision tree along with a simple inference mechanism, has been praised for comprehensibility. The most comprehensible decision trees have been designed for perfect symbolic data. Classical crisp decision trees (DT) are widely applied to classification t...
متن کاملA Knowledge Representation Formalism to Process Vague Medical Queries
Many fields of application deal with vague and fuzzy information. Thus the need of tools that are able to handle this kind of data is obvious. We concentrate on the extension of well-known terminological knowledge representation systems with appropriate methods. Classical terminological knowledge representation systems are based on two-valued logics. To solve problems of uncertainty a more expr...
متن کاملNew Representation Theorem for Many-valued Modal Logics
We propose a new definition of Representation theorem for many-valued modal logics, based on a complete latice of algebraic truth values, and define the stronger relationship between algebraic models of a given logic L and relational structures used to define the Kripke possible-world semantics for L. Such a new framework offers clear semantics for the satisfaction algebraic relation, based on ...
