Russian Summer School in Information Retrieval

Friday, August 14th, 2009, posted by Djoerd Hiemstra

I will give several lectures on information retrieval modeling at the Russian Summer School in Information Retrieval, which will be held September 11-16, 2009 in Petrozavodsk, Russia. The main audience of the school is graduate and post-graduate students, young scientists and professionals who have experience in development of information retrieval applications. The school will host approximately 100 participants.

Information Retrieval Modeling
There is no such thing as a dominating model or theory of information retrieval, unlike the situation in for instance the area of databases where the relational model is the dominating database model. In information retrieval, some models work for some applications, whereas others work for other applications. For instance, vector space models are well-suited for similarity search and relevance feedback in many (also non-textual) situations if a good weighting function is available; the probabilistic retrieval model or naive Bayes model might be a good choice if examples of relevant and nonrelevant documents are available; Google’s PageRank model is often used in situations that need modelling of more of less static relations between documents; region models have been designed to search in structured text; and language models are helpful in situations that require models of language similarity or document priors; In this tutorial, I carefully describe all these models by explaining the consequences of modelling assumptions. I address approaches based on statistical language models in great depth. After the course, students are able to choose a model of information retrieval that is adequate in new situations, and to apply the model in practice.

Welcome to DIR 2009

Friday, January 30th, 2009, posted by Djoerd Hiemstra

Welcome to the 9th Dutch-Belgian Information Retrieval Workshop (DIR). I very well remember the DIR workshop in 2001 that was also organized in Twente. It took place exactly one day before my PhD defense, to give us the opportunity to have one of the PhD committee members, Stephen Robertson, as the keynote speaker. I am proud to see that DIR does not need PhD defenses any more to attract excellent keynotes. This year, DIR presents Rene van Erk, Director of Product- and Business Development Europe at Wolters Kluwer as the industry keynote; we present professor Gerhard Weikum, Scientific Director at the Max-Planck Institute for Informatics, as the academic keynote. We also present comedian Daniel van Veen as the “cultural keynote” to let our participants taste a bit of our university’s unique campus activities.

We have tried this year to especially encourage PhD students and researchers from industry to submit their research. Each submission was reviewed by at least two and often three or four program committee members. We thank the program committee members for their high quality reviews. Of 15 submissions to DIR, 12 were accepted. Another 5 submissions were accepted as poster presentations. Four papers were written with participation from industry and most other papers have a PhD student as the first author.

Special thanks to the Netherlands Research School for Information and Knowledge Systems (SIKS) for sponsoring the participation of Dutch SIKS members, to the Werkgemeenschap Informatiewetenschap (WGI) for providing a solid financial basis for organizing DIR now and in the future, to the Netherlands Organization of Scientific Research (NWO) for sponsoring the travel and hotel costs of our international keynote speaker Gerhard Weikum, to the Centre for Telematics and Information Technology (CTIT) for sponsoring the proceedings, to the University of Twente and to Cultural Center the Vrijhof for sponsoring our cultural activity on Monday.

To an inspiring DIR 2009!

Call for Participation: Dutch-Belgian IR workshop

Friday, January 9th, 2009, posted by Djoerd Hiemstra

The 9th Dutch-Belgian Information Retrieval Workshop (DIR) will take place at the University of Twente, Enschede, the Netherlands, on February 2-3, 2009. The workshop is organised under the auspices of the Working Community on Information Sciences (WGI) and the School for Information and Knowledge Systems (SIKS). The workshop is sponsored by NWO, CTIT and the University of Twente.

Keynote Speaker: prof. Gerhard Weikum (MPII, Saarbruecken, Germany) Gerhard Weikum is Research Director at the Max-Planck Institute for Informatics (MPII) in Saarbruecken, Germany, where he is leading the department on databases and information systems. Prof. Weikum is ACM fellow and a renowned expert in the field of Databases. He received the VLDB 10-Year Achievement Award in 2002. Since then, he focused on several information retrieval problems such as peer-to-peer search, search efficiency, and database and search integration, resulting in for instance 6 full papers at the last SIGIR conferences.

Due to the cooperation between SIKS, SIKS-members can participate without paying entrance fee. Especially PhD-students working on the SIKS-focus “Web based Information Systems” and “Data management, Storage and Retrieval” are strongly encouraged to participate. There is a limited number of registrations for SIKS members. Registrations will be honored in a first come-first serve manner.

Participants of DIR are invited to the Annual Meeting of the Werkgemeenschap Informatieschap which is directly following DIR on Tuesday.

Dutch-Belgian Database Day 2008

Tuesday, September 16th, 2008, posted by Djoerd Hiemstra

The Dutch Belgian Database Day (DBDBD) is a yearly one-day workshop organized in a Belgian or Dutch university, whose general topic is database research. DBDBD invites submissions (1 page abstract) on a broad range of database and database-related topics, including but not limited to data storage and management, theoretical database issues, database performance, data mining, information retrieval, data semantics, querying, ontologies etc. Based on the submissions, the workshop will be organized in different sessions each covering a particular topic.

At the DBDBD, junior researchers from the Netherlands and Belgium can present their recent results. It is an excellent opportunity to meet up with your Belgian/Dutch colleagues, and to get informed about the (recent) database-related research performed in Belgian/Dutch universities. The workshop is also open to non-Belgian/Dutch participants (presentations are in English).

The DBDBD 2008 is organized under auspices of SIKS, the Dutch research school for information and knowledge systems and the Belgian Graduate School in Computing Science (GRASCOMP). This year, DBDBD will be held at the Arsenal, located at the heart of the charming city of Namur (Belgium), on Friday October 10th, 2008.
