Large-Scale Data Integration Seminar (FSS 2020)

This seminar covers topics related to integrating data from large numbers of independent data sources. This includes large-scale schema matching, identity resolution, data fusion, set completion, data search and data exploration, and data profiling.

• This seminar is organized by Prof. Dr. Christian Bizer, Anna Primpeli, Ralph Peeters.
• The seminar is available for master students of the Data Science and Business Informatics programs.
• Slides from the Kick Off Meeting: tbd

In this seminar, you will

• Read, understand, and explore scientific literature
• Summarize a current research topic in a concise report (10–12 pages)
• Give a presentation about your topic (before the submission of the report)

The kick-off meeting will take place on Monday, 02.03 room C1.01 (building B6 entrance C).

You can download the slides of the kick-off meeting here.

• Attending Web Data Integration and Data Mining I before the seminar is strongly recommended
• Report and presentation language: English

1. Please register for the seminar via the centrally-coordinated seminar registration.
2. After you have been accepted into the seminar, please email us your three preferred topics from the list below.
   We will assign topic to students according to your preferences.
3. Attend the kickoff meeting on Monday, 2 March at 10:00 in room B6 C1.01 (library room).
