Information Management (2005–08)

Note: This page will no longer be updated after spring term 2008. For teaching and research on information management, see Software Systems (for database systems) and Algorithms and Machine Learning (for data mining).


The specialisation area of Information Management (Information Systems) at the Department of Computer Science studies methods, techniques, and tools needed in processing large volumes of data, often implemented as a database, frequently also using structured representations such as XML. The education in the specialisation area covers database management, text and document management, information retrieval, and data mining.

The core of the curriculum of Information Management contains obligatory courses on database management, database applications, and data mining: Introduction to databases, Database application, Database design, and Data-mining methods. Besides these, special courses are offered on digital media technology, management of research data, the XML metalaguage, spatial data processing, query languages, data mining, information retrieval methods, transaction processing, distributed databases, data warehousing, processing of structured documents, processing of large document collections, statistics of text corpora, word senses. The courses are designed to teach conceptual and physical data models, how to choose the data-management methods best suited to specific problems, how to analyse large data collections, how to manage text and document collections, and how to implement challenging information systems. More specific subareas are covered by seminars on varying topics.

The research in information systems is strongly focused on data mining and document management, including language technology. Techniques of analyzing and mining data from various sources for useful information are the key research topics. The research includes both method development and applications, for instance in gene technology (gene mapping and diagnostics), bioinformatics (biological data mining), proactive computing (context recognition by user situation data analysis), and information retrieval and publishing industry (cross-language question answering, information extraction in text, knowledge-support systems, topic detection and tracking). Research in the database area is focused on database structures and transaction management. Computer-aided teaching environments have been developed for database courses.


Much of our research is done within the From Data to Knowledge research unit, a Center of Excellence in Research, and Basic Research Unit of Helsinki Institute for Information Technology.
