The 36th Annual Conference of the German Classification Society (GfKl) v

The 36th Annual Conference of

the German Classification Society (GfKl) on

Data Analysis, Machine Learning and Applications Program & Abstracts Preface Message from the GfKl 2012 Chairs We would like to cordially welcome you to the 36th Annual Conference of the German Classification Society, taking place in Hildesheim, Germany.

The GfKl has become 36 years young. In these years, we saw the core topics of the conference crystallize themselves into thematic areas. This year, for the first

time, these areas were made explicit and their coordination was undertaken by dedicated Area Chairs. We are proudly hosting five Areas:

• Statistics and Data Analysis (SDA), organized by Hans-Hermann Bock, Christian Henning and Claus Weihs

• Machine Learning and Knowledge Discovery (MLKD), organized by Lars Schmidt-Thieme and Myra Spiliopoulou

• Data Analysis and Classification in Marketing (DACMar), organized by Daniel Baier and Reinhold Decker

• Data Analysis in Finance (DAFin), organized by Michael Hanke and Krzysztof Jajuga

• Biostatistics and Bio-informatics, organized by Anne-Laure Boulesteix and Hans Kestler

• Interdisciplinary Domains (InterDom), organized by Andreas Hadjar, Sabine Krolak-Schwerdt and Claus Weihs

• and the Workshop Library and Information Science (LIS’2012) organized by Frank Scholze Obviously, the subjects accommodated in the five areas are not sharply separated.

We have fostered links and interactions among them, culminating in the three plenary and six semi-plenary talks, and in the three invited sessions that cover research

advances spanning more than one area. Our invited sessions are:

• Ensemble Methods in Clustering and Classification, organized by Berthold Lausen vii viii Preface

• Applications in Empirical Educational Research Based on Secondary Data, organized by Sabine Krolak-Schwerdt and Alexandra Schwarz

• Dynamic Cluster Analysis — Theory and Practise, organized by Jozef Pociecha under the auspices of the Polish Classification Society Next to the plenary and semi-plenary talks, our scientific program accommodates 130 contributions, 16 of them in the LIS workshop. As expected, the lion’s share among the contributions comes from Germany, followed by Poland, but we have contributions from all over the world, stretching from Portugal to Ukraine, from Canada and USA to Japan and Thailand.

Organizing such a conference with its parallel, interleaved events is not an easy task. It requires coordination of many individuals and on many issues, and lives from the tremendous effort of engaged scientists and of the dedicated teams in Hildesheim and Magdeburg. We would like to thank the Area Chairs for their hard work in conference advertisement, author recruitment and submissions evaluation, and the three Chairs of the invited sessions for winning renowned presenters to complement the main areas with inter-area subjects of major interest. We are particularly indebted to the Polish Classification Society for its involvement and presence in the GfKl 2012.

We are proud to announce the best paper awards of GfKl 2011. This year, we

have honoured two papers:

1. Sarah Frost and Daniel Baier (University of Cottbus) elaborate on the performance of the Earth Mover’s Distance on image clustering; and

2. Florent Domenach and Ali Tayari (University of Nicosia) discuss implications of Axiomatic consensus properties.

We would like to congratulate the prize winners and would like to thank the Best Paper Awards Jury members H.H. Bock, R. Decker, B. Lausen, A. Ultsch, and C.

Weihs for their excellent work. The awarded papers appear as part of the GfKl 2011 postconference proceedings.

We would like to thank the EasyChair GfKl 2012 administrator, Miriam T¨ dten o (master student of the ’Data & Knowledge Engineering’ degree at the Otto-vonGuericke University Magdeburg) for her tireless work in troubleshooting and assistance during submissions, evaluation and camera-ready preparation and contribution to the abstracts volume, and Silke Reifgerste, the financial administrator of the KMD research lab at the Otto-von-Guericke University Magdeburg for her fast and competent treatment of all financial matters concerning the Magdeburg team.

Further we would like to thank Kerstin Hinze-Melching (University of Hildesheim) for her help with the local organization, J¨ rg Striewski and Uwe Oppermann, our o technicians in Hildesheim, for technical assistance, Selma Batur (master student at University of Hildesheim) for help with the

Abstract

proceedings and preparation of the conference and our assistants in Hildesheim for the conference Fabian Brandes, Christian Brauch, Lenja Busch, Sarina Flemnitz, Sophia Graefe, Stephan Reller, Nicole Reuss and Kai Wedig.





GfKl 2012 is not ending with the conference in Hildesheim. According to our long tradition of post-conference proceedings, we will open the EasyChair GfKl Preface ix 2012 site again from August 2012, and invite the conference authors to submit the full version of their work for the peer-reviewing phase scheduled for fall 2012. Accepted papers will be published by Springer.

We wish you a productive, inspiring conference and a pleasant stay in Hildesheim!
