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.

Fast computation of concept lattices using data mining techniques
(2000)
We present a new algorithm called TITANIC for computing concept lattices. It is based on data mining techniques for computing frequent itemsets. The algorithm is experimentally evaluated and compared with B. Ganter's Next-Closure algorithm.

Supporting co-operative work in apron control and resource management offices on airports
(P.C. Cacciabue, Institute for System Informatics and Safety, European Commission, Joint Research Centre Ispra, Italien, 2000-06-26)
A high demand exists to increase the efficiency of present airport ground facilities and the co-ordination of traffic and services. The Traffic Office plays a crucial role in managing the airport. The main tasks of the Traffic Office is management of equipment, services, and ressources based on the flight schedule and resolving conflicts arising from deviations from the schedule. A new tool will support information exchange between Traffic Office and other facilities on the airport.

Das Spektrum möglicher Antworten
(2000)
Seit gut einem Jahrzehnt wird über die so genannte Globalisierung viel geschrieben und geforscht. Es ist an der Zeit Zwischenbilanz zu ziehen. Hat sich mittlerweile ein Konsens herausgeschält, was Globalisierung eigentlich ist, was ihre Ursachen sind und welche Konsequenzen sie zeitigt? Oder haben zumindest die jeweiligen Interpretationen klare Konturen gewonnen? Der Autor gibt hier zunächst einen kurzen, keinesfalls Vollständigkeit beanspruchenden Überblick zum Stand der Diskussionen zum "Globalisierungskomplex" ...
