I wrote a document with many good alternative solutions to the assignments. At some places I added a comment explaining an important point or pointing out common mistakes. Note that the document is not complete! There may be more correct answers. Just compare your solutions to these to find out if you made some mistakes and why. If you are not sure if your solution to a particular question is correct or not, just send me an e-mail

Welcome to the course “XML & Databases 1″. Following this course means you will read about some of the latest research on XML databases. We will discuss XML querying with XPath and XQuery, publishing of relational data, a lot about relational storage structures for XML data and query processing techniques, and lectures on full-text querying, distributed querying and querying stand-off data. To obtain the study material necessary for this course, you need to buy the reader “XML & Databases 1 & 2″.It is possible to use the old readers from 2008/2009 or 2009/2010. We hope you will enjoy the course.

The exams are corrected. Of 19 students who took the exam, 13 passed (68%). Because of Ascension Day (”Hemelvaartsdag”), it will probably take a few days before the individual results are known.

Search for the Future

Friday, October 17th, 2008, posted by Djoerd Hiemstra

Information Retrieval is the discipline that studies computer-based search tools. Many applications that handle information on the internet would be completely inadequate without the support of information retrieval technology. How would we manage our email without spam filtering? How would we find information on the world wide web if there were no web search engines? The rise of web search engines has been one of the major success stories in computer science of the last decade: Internet and search companies like Google and Yahoo are now among the world’s most influential information technology companies.

Today, search technology is provided and developed by major search providers like Google and Yahoo, and by small specialized companies with specialized staff. But as search technology matures, it will have to be available to non-expert application developers as well. A major obstacle to achieve this, is the lack of theories and high-level abstractions of search systems and the lack of declarative query languages. Another obstacle is the lack of methods to handle non-textual data, such as images, audio and video. Several projects of the Database Group of the University of Twente try to solve these problems for application areas such as Entity Search, Expert Search, Video Search, and Distributed Search. The models and approaches that are developed in these projects are evaluated on large scale, realistic testbeds, and implemented in the group’s open source search system PF/Tijah, a search system that combines keyword queries with structured queries on XML databases. The research contributes to the several courses in the university’s graduate programs, for instance Information Retrieval, and XML & Databases 1 and XML & Databases 2.
