CBU Winter School in Information Technology
Saint Petersburg, 28 January-6 February 2008

The topics of the 3nd CBU winter school are Data Security and Structured Documents. There will be two courses on information retrieval, and one course on digital systems.

Students are coming mainly from the universities participating in the CBU IT pilot:

  • Lappeenranta University of Technology
  • Petrozavodsk State University
  • St. Petersburg State Polytechnical University
  • St. Petersburg State University
  • University of Helsinki
  • University of Joensuu
  • University of Kuopio
Also students from other universities may be accepted.

The courses are suitable for Master's degree students on the 4th or 5th year of studies and for postgraduate students.

TT1: Course on information retrieval, "Document Clustering" given by Associate
Prof. Vladimir Dobrynin, St.Petersburg State University, Russia

Document clustering is used in two different search scenarios. The first one is search result clustering. In this case on-line clustering is used with goal to improve presentation of search results returned by a web search engine. Second scenario is related to so called cluster-based
search. In this case off-line clustering is used to disclose internal structure of a document corpus. Standard application of this approach is enterprise search.

We will study both well known and new clustering algorithms including k-means, Information Bottleneck and Contextual Document Clustering. Some of these algorithms are based on Information Theory ideas so an overview of this theory will be presented also. Finally we will discuss application of clustering in real information retrieval systems.

 


TT2: Course "Introduction to Digital Systems" given by Prof. Evgeny I. Veremey, St.Petersburg State University, Russia

The Lectures course "Introduction to Digital Systems" provides a short summary of the theory of discrete-time signals and dynamic systems. Whenever a computer is used in measurement, signal processing or control applications, the data (as seen from the computer) and systems involved are naturally discrete-time because a computer executes program code at discrete points of time. In this connection the course is intended as introduction material for master program students specialized in the area of computing and control theory. It includes the base positions in mathematical modeling, analysis and synthesis of discrete time systems. Besides that computer modeling and simulation on the base of Matlab also are considered.

 


TT3 : Course "Introduction to Information Retrieval" given by Associate Prof. Vitaly Klyuev, University of Aizu, Japan.

Information retrieval (IR) deals with the representation, storage, organization of, and access to information items. The aim is to provide the user with easy access to information in which s/he is interested. Expansion of the Internet and the advent of new mass storage devices have had a significant effect on research in this area. Nowadays, data sets are very huge, they are continually changeable, and they are distributed over the net. Modern methods and techniques of IR cope with such complex data structures.

In this course, we are going to investigate the current technologies applied to IR: models to represent data and information, algorithms to search and retrieve information, approaches to crawl information from the Web, etc. The focus of this course is on text retrieval. Students will be provided with state-of-the-art technologies in the area of collecting, indexing, searching and retrieving data and information which work well with very large data sets.
