For bachelor students we offer German lectures on database systems in addition to paper- or project-oriented seminars. Within a one-year bachelor project, students finalize their studies in cooperation with external partners. For master students we offer courses on information integration, data profiling, and information retrieval enhanced by specialized seminars, master projects and we advise master theses.
Most of our research is conducted in the context of larger research projects, in collaboration across students, across groups, and across universities. We strive to make available most of our datasets and source code.
Boolean queries over titles and abstracts in library catalogs gave rise to a new ﬁeld of Computer Science that today is known by the name of Information Retrieval. The achievements in this field have enabled search technologies that bring large amounts of information almost instantly to our finger tips. Today’s search engines can index billions of documents and enable thousands of queries per second. They exploit information retrieval techniques on rich content features to satisfy the daily needs of hundreds of millions of users all around the globe. These techniques will make up the main subject of this lecture.
