DSC/e: Competences and Research Programs 28 groups and 420+ people involved

Context: Why are we using data science, does it have the intended effect, and will

people accept it?

Analysis: How to turn data into real value (models, answers/decisions, and

visualizations/insights)?

Enabling technologies: How to get the data and deal with computational/

infrastructural challenges (big data and hard questions)?

Process Mining

Example: Process Mining as the Bridge Between Data Science and Process Science

Process Mining: Spreadsheet for behavior

• Input: events (“things that have happened”)

• Mandatory per event:

• case identifier

• activity name

• timestamp/date

• Optional

• resource

• transaction type

• costs

• …
