Large-Scale Data Integration Seminar (FSS2019)

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, Yaser Oulabi.
• The seminar is available for master students of the Data Science and Business Informatics programs.
• Slides from the Kick Off Meeting

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)

• Attending the courses Web Data Integration and Data Mining I before the seminar is recommended
• The report has to be written using Latex
• Report and presentation have to be in English

1. Please register for the seminar via the centrally-coordinated seminar registration that is performed for the first time this semester.
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, 25 February at 10:00 in room B6 C1.01 (library room).
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
