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.

schließen

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.

Please do not hesitate to reach out directly to us, if you cannot find a paper, slides, or other research artifacts.

Statistical Data

There are numerous sources for statistical data sets: companies, government agencies, international organizations, etc. Statistical data is usually

  • of numerical type
  • collected in fixed intervals over a certain time period, and
  • reveals certain short-term and long-term trends.
source: wikipedia.org

Event Data

Event data can be gathered from various (mostly unstructured) sources, such as Wikipedia, Freebase, News Archives, and so on. In the context of this seminar, an event is described by its

  • type,
  • location, and
  • (starting) point in time.

Augmenting Statistical Data

Our goal is to detect certain trends in statistical data and automatically relate them to the historical events that triggered these events based on specific rules previously learned by our system.

Proposed Architecture

The following diagram depicts a possible architecture for the system. The green boxes each represents a specific component a team of students will be working on.
