Talk

April 13, 2010: Mike de Dood will give an intermedidate talk of his Bachelor thesis titled with Digital Image Classification of Space Galaxies.

Paper about Fraud Detection in Telecommunication Data

The following paper concerns with the mining of telecommunication data: Discovering Fraud Behaviour in Call Detailed Records. It has been published in the Book "Mining your own Business - Telecommunication" (see publication list).

Defense - Master Thesis

Ronny Heinz: Do you know who you are? Profiling Authors on the basis of published paper summaries.
29th of January, 2010: 10h00, Room B02

Nowadays we have access to a huge amount of articles and documents over the internet. This gives rise to different problems: plagiarism, search results containing multiple times the same document, inefficient search using keywords, etc. In this Master's Thesis we try to address some of the problems in the case of the search for scientific publications. We use the author as an important source to find new publications which are of interest to us. Instead of using the publications themselves, we use the abstracts of the scientific publications from a given author to generate a profile for this author. Each of the abstracts is transformed into a graph. The profile is then generated using methods performing different operations on the graphs corresponding to abstracts of the given author. The profile can then we used to find similar authors or to match an ACM category to the author.Our experiments show that we can successfully find similar authors and assign ACM categories. Additionally they show that the profile must not be too broad and not too restricted. We implemented the system in a workbench, where the user can experiment with the different operations and methods to create the profile. Through the use of such a system, we could improve the search for scientific publications by returning not only the publications of an author but also similar authors. Furthermore giving the authors an ACM category, it is possible to easily search for an author in a specific category.

Talk

Christoph Schommer: Data Mining and Cognition. Information Day, European Commission. Luxembourg, 14 January 2010.

We understand Data Mining/Knowledge Discovery as a cognitive process, which is a life-cycle of Signals, Patterns Noise, Relevances, Surprise and Disappointment, and Consequences. Cognitive Components are inherent, for example Learning, Interpretation, Creativity, Interaction, Knowledge Use, and Strategy Finding. The talk summarizes this ideas and gives three examples: Adaptive Management of Artificial Thoughts, Conviviality within/between Individuals and Groups, and an Open Information Addressing with Steganography.

Talk

François Beckius: The Search for Topic Signatures
  • 16th December, 2009 (Wednesday)
  • 15:45 hr. to 16:45 hr.
  • Room E112
Summary :
I will be presenting a summary of the work I have done on sample data received from the ESPON project in order to extract topic signatures using the WordStat tool. The main points are: approaches taken, problems encountered, results, and possible improvements.

Talk

Ronny Heinz: Do you know who you are? - Creating author profiles by abstracts of scientific publications.
  • 9th December, 2009 (Wednesday)
  • 11:00 hr. to 12:00 hr.
  • Room E012
Summary :
The Invited Talk concerns the profiling of authors by using the abstracts of scientific publications. For that, the abstract is transformed into a individual graph-based framework, which is achieved by a couple of operations on graphs. Using ACM classification as an ontology backbone, a better understanding of the authors' interests can be achieved.

Talk

Maria Biryukov: Mining The Bibliographic Database DBLP
  • Date : 2th December, 2009 (Wednesday)
  • Time : 15:45 hr. to 16:45 hr.
  • Place : Room E012

Talk

Sascha KAUFMANN : e-Conviviality in Web Systems by the Wisdom of Crowds
  • Date : 4th November, 2009
  • Time : 15:45 hr. to 16:45 hr.
  • Place : Room G103
Summary :
We motivate the idea of e-conviviality in web-based systems and argue that a convivial social being deeply depends on the implicit and explicit co-operation and collaboration of natural users inside a community. We believe that a (individual) conviviality benefits from the wisdom of crowds, meaning that a continuously and dynamic understanding of the user's behaviour can heavily influence the individual well being. In this respect, we are currently implementing the system CUBA (conviviality and user behaviour analysis), which aims to find novel ways to support users during their web site Invited Visits while discovering their interests. CUBA comes up with certain recommendations and suggestions, which base on a common behaviour of the "Wisdom of Crowds". For example, concepts with respect to time, space, and user-based actions are considered.

Talk

Jayanta Poray: Towards a healthy Explorative Mind-map framework and beyond
  • Date : 21st October, 2009 (Wednesday)
  • Time : 15:45 hr. to 16:45 hr.
  • Place : Room F212
Summary :
The extraction of patterned information from the raw data source is the key to set-up an artificial cognitive system. In this regard the design of an explorative mind-map for the conversational text streams and ensure its healthy status is a challenging task, involves many machine learning steps. Also the study of human mind theory may influence the overall process. Finally the structured mind-map may used for many real applications. In our naive approach we are formalizing the computational trust with the help of several mind-map elements and their derivatives.
