This book constitutes the thoroughly
refereed proceedings of the Fourth International
Symposium on Data-Driven Process Discovery and Analysis held in Riva del Milan,
Italy, in November 2014.

The five revised full papers were carefully selected from
21 submissions. Following the event, authors were
given the opportunity to improve their papers with the insights they gained
from the symposium. During this edition, the presentations and discussions
frequently focused on the implementation of process mining algorithms in
contexts where the analytical process is fed by data streams. The selected
papers underline the most relevant challenges identified and propose novel
solutions and approaches for their solution.
