Learning Fuzzy Concept Definitions
A b s t r a c t --The symbolic approach to machine learning has developed algorithms for learning F i r s t O r d e r L o g i c c o n c e p t d e f i n i t i o n s . Nevertheless, most of them are limited because of their impossibility to cope with numeric features, typical of real-world data. In this paper, a method to face this problem is proposed. In particular, an extended version of the sy...
متن کاملConcept Lattice from Structured and Fuzzy DataR
The problem of acquiring knowledge from a set of data is fundamental for humans to understand their experiences and to classify new observations. In this paper, we are concerned with acquiring concepts from data that may not be precisely or perfectly deened. We show the utility of lattice fuzzy sets to modelize uncertainty and imprecision for complex and structured data in rich domains such as ...
متن کاملDWRank: Learning concept ranking for ontology search
With the recent growth of Linked Data on the Web there is an increased need for knowledge engineers to find ontologies to describe their data. Only limited work exists that addresses the problem of searching and ranking ontologies based on a given query term. In this paper we introduce DWRank, a two-staged bi-directional graph walk ranking algorithm for concepts in ontologies. DWRank characteri...
متن کاملBipolar fuzzy graph representation of concept lattice
Formal Concept Analysis (FCA) is a mathematical framework for knowledge processing tasks. FCA has been successfully incorporated into fuzzy setting and its extension (interval-valued fuzzy set) for handling vagueness and impreciseness in data. However, the analysis in such settings is restricted to unipolar space. Recently, some applications of bipolar information are shown in bipolar fuzzy gra...
متن کاملWhat is a fuzzy concept lattice?
The paper is an overview of several approaches to the notion of a concept lattice from the point of view of fuzzy logic. The main aim is to clarify relationships between the various approaches.
