# Formal Concept Analysis: Foundations and Applications by Rudolf Wille (auth.), Bernhard Ganter, Gerd Stumme, Rudolf

By Rudolf Wille (auth.), Bernhard Ganter, Gerd Stumme, Rudolf Wille (eds.)

Formal thought research has been constructed as a box of utilized arithmetic according to the mathematization of notion and notion hierarchy. It thereby permits us to mathematically characterize, study, and build conceptual buildings. The formal inspiration research technique has been confirmed winning in a variety of software fields.

This booklet constitutes a finished and systematic presentation of the cutting-edge of formal inspiration research and its purposes. the 1st a part of the booklet is dedicated to foundational and methodological themes. The contributions within the moment half reveal how formal proposal research is effectively used open air of arithmetic, in linguistics, textual content retrieval, organization rule mining, facts research, and economics. The 3rd half offers purposes in software program engineering.

Analisi matematica

Nel quantity vengono trattati in modo rigoroso gli argomenti che fanno parte tradizionalmente dei corsi di Analisi matematica I: numeri reali, numeri complessi, limiti, continuità, calcolo differenziale in una variabile e calcolo integrale secondo Riemann in una variabile. Le nozioni di limite e continuità sono ambientate negli spazi metrici, di cui viene presentata una trattazione elementare ma precisa.

Multicriteria and Multiobjective Models for Risk, Reliability and Maintenance Decision Analysis

This publication integrates a number of standards strategies and strategies for difficulties in the chance, Reliability and upkeep (RRM) context. The innovations and foundations on the topic of RRM are thought of for this integration with multicriteria techniques. within the ebook, a common framework for construction choice versions is gifted and this can be illustrated in quite a few chapters by means of discussing many alternative choice types with regards to the RRM context.

Formal context of the result of an attribute exploration in music a number of TOSCANA-systems have been developed and used in practice (see, for instance, [SVW93], [Vg95], [Kf96], [EKSW00], [GH00], [KV00], [RW00], [BSWZ00], [Sc04], [Ks05]). But other TOSCANA-systems have not been established although they would be urgently needed. For instance, together with the Center of Medical Informatics at Frankfurt University, we have designed a research project for developing a medical information system for practising doctors to support their on-the-spot examinations and treatments.

The questions of the exploration were created by the software “ConImp”, programmed by P. Burmeister [Bu00] based on the Ganter-Algorithm [Ga86] (see also [GW99a]) which guarantees that the ﬁnal list of valid attribute implication forms the Duquenne-Guigues-Basis of all attribute implications of the resulting context. 10 Concepts Have Motivational and Emotional Qualities According to [Se01], concepts also have a dynamic, motivational and emotional nature. They essentially contain an evaluating attitude.
