A Description Logic for Vague KnowledgeC
نویسندگان
چکیده
This work introduces the concept language ALC F M which is an extension of ALC to many-valued logics. ALC F M allows to express vague concepts, e.g. more or less enlarged or very small. To realize this extension to many-valued logics, the classical notions of satissability and subsumption had to be modiied appropriately. For example, ALC F M-concepts are no longer either satissable or unsatissable, but they are satissable to a certain degree. The main contribution of this paper is a sound and complete method for computing the degree of subsumption between two ALC F M-concepts.

Fuzzy Description Logic Programs
Description Logic Programs (DLPs), which combine the expressive power of classical description logics and logic programs, are emerging as an important ontology description language paradigm. In this study, we present fuzzy DLPs, which extend DLPs by allowing the representation of vague/imprecise information.
متن کاملDealing with Incompleteness and Vagueness in Inductive Logic Programming
Incompleteness and vagueness are inherent properties of knowledge in several real world domains and are particularly pervading in those domains where entities could be better described in natural language. In order to deal with incomplete and vague structured knowledge, several fuzzy extensions of Description Logics (DLs) have been proposed in the literature. In this paper, we address the issue...
متن کاملReliability Measures Measurement under Rule-Based Fuzzy Logic Technique
In reliability theory, the reliability measures contend the very important and depreciative role for any system analysis. Measurement of reliability measures is not easy due to ambiguity and vagueness which exist within reliability parameters. It is also very difficult to incorporate a large amount of uncertainty in well-established methodologies and techniques. However, fuzzy logic provides an...
متن کاملAn Inductive Logic Programming Approach to Learning Inclusion Axioms in Fuzzy Description Logics
Fuzzy Description Logics (DLs) are logics that allow to deal with vague structured knowledge. Although a relatively important amount of work has been carried out in the last years concerning the use of fuzzy DLs as ontology languages, the problem of automatically managing fuzzy ontologies has received very little attention so far. We report here our preliminary investigation on this issue by de...
متن کاملAnswering Vague Queries in Fuzzy DL-Lite
Fuzzy Description Logics (fuzzy DLs) allow to describe structured knowledge with vague concepts. Unlike classical DLs, in fuzzy DLs an answer is a set of tuples ranked according to the degree they satisfy the query. In this paper, we consider fuzzy DL-Lite. We show how to compute efficiently the top-k answers of a complex query (i.e. conjunctive queries) over a huge set of instances.
