Large-Scale Data Integration Seminar (FSS 2022)

This seminar covers topics related to integrating data from large numbers of independent data sources. The specific focus of the FSS 2022 edition of the seminar are Data Lakes which are large uncurated collections of data having different degrees to structuredness. The seminar will review the concept of data lakes as well as their use cases and will cover methods for profiling data lakes, searching within data lakes, as well as for integrating and cleansing data from data lakes.

• This seminar is organized by Prof. Dr. Christian Bizer, Ralph Peeters, Alexander Brinkmann.
• The seminar is available for master students of the Data Science and Business Informatics programs.
• Slides from the kickoff meeting.

In this seminar, you will

• read, understand, and explore scientific literature
• critically summarize the state-of-the-art concerning your topic
• give a presentation about your topic (before the submission of the report)

• 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 in Portal2
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 in which we will discuss general requirements for the reports and presentations as well as answer initial questions about the topics
4. You will be assigned a mentor, who provides guidance and one-to-one meetings
5. Work individually throughout the semester: explore literature, create a presentation, and write a report
6. Give your presentation in a block seminar towards the end of the semester
7. Write and submit your seminar thesis until July 2022.
