Syntax des Neuhochdeutschen bis zur Mitte des 20. Jahrhunderts
(De Gruyter, 2000)
Während die Erforschung des Frnhd. in den letzten 20 Jahren einen stürmischen Aufschwung erlebte, ist das jüngere Nhd. (Mitte 17. Jh. bis Mitte 20. Jh.) noch immer verhältnismäßig schlecht erforscht. Dabei ist „die Beantwortung vieler diskutabler und unklarer Fragen der Herausbildung und Weiterentwicklung des gegenwärtigen Deutsch gerade in dieser Periode zu finden“. Einer der Gründe für die relative Vernachlässigung der Syntaxgeschichte nach 1700 mag darin liegen, daß nach gängiger Auffassung das grammatische System ...

The Museum’s Discourse on Art
(Stanford University Press, 2000)
When the Cerman museum curator Max J. Friedländer attempted to describe the field of discourse in which he situated his art criticism, he confronted two different attitudes of art-historical scholarship and associated them with clearly distinct images of professional behavior. There is good reason to assume that Friedländer intended to create the impression of an archetypal metaphor for his audience of 1920. Yet, besides its function as a literary device, the juxtaposition that he offered to his readers referred to ...

Conceptual information systems discussed through an IT-security tool
(2000)
Conceptual Information Systems are based on a formalization of the concept of "concept" as it is discussed in traditional philosophical logic. This formalization supports a human-centered approach to the development of Information Systems. We discuss this approach by means of an implemented Conceptual Information System for supporting IT security management in companies and organizations.

A contextual-logic extension of TOSCANA
(2000)
The aim of this paper is to indicate how TOSCANA may be extended to allow graphical representations not only of concept lattices but also of concept graphs in the sense of Contextual Logic. The contextual-logic extension of TOSCANA requires the logical scaling of conceptual and relatioal scales for which we propose the Peircean Algebraic Logic as reconstructed by R. W. Burch. As graphical representations we recommend, besides labelled line diagrams of concept lattices and Sowa's diagrams of conceptual graphs, particular ...

Mining minimal non-redundant association rules using frequent closed itemsets
(2000)
The problem of the relevance and the usefulness of extracted association rules is of primary importance because, in the majority of cases, real-life databases lead to several thousands association rules with high confidence and among which are many redundancies. Using the closure of the Galois connection, we define two new bases for association rules which union is a generating set for all valid association rules with support and confidence. These bases are characterized using frequent closed itemsets and their ...

CEM - visualization and discovery in Email
(2000)
This paper presents a lattice-based visual metaphor for knowledge discovery in electronic mail. It allows a user to navigate email using a visual lattice metaphor rather than a tree structure. By using such a conceptual multi-hierarchy, the content and shape of the lattice can be varied to accommodate any number of queries against the email collection. The system provides more flexibility in retrieving stored emails and can be generalised to any electronic documents. The paper presents the underlying mathematical ...

Conceptual knowledge discovery and data analysis
(2000)
In this paper, we discuss Conceptual Knowledge Discovery in Databases (CKDD) in its connection with Data Analysis. Our approach is based on Formal Concept Analysis, a mathematical theory which has been developed and proven useful during the last 20 years. Formal Concept Analysis has led to a theory of conceptual information systems which has been applied by using the management system TOSCANA in a wide
range of domains. In this paper, we use such an application in database marketing to demonstrate how methods and ...

CEM - a conceptual Email manager
(2000)
CEM is an email management system which stores its email in a concept lattice rather than in the usual tree structure. By using such a conceptual multi-hierarchy, the system provides more flexibility in retrieving stored emails. The paper presents the underlying mathematical structures, discusses requirements for their maintenance and presents their implementation.
