2. Motivation
Starting a study in MSR is hard as it involves
expensive tasks:
➔ Download source code repositories.
➔ Extract useful information from raw data.
➔ Calculate metrics.
➔ Typically, it’s required to install and configure
tools locally.

3. MetricMiner
A web application for supporting common MSR
studies steps and possibly making use of cloud
computing to scale.

9. Replication study
To validate our tool, we replicated a study published
by Soetens and Demeyer (2010).
Does refactoring improve code complexity?
Original study:
➔ 1 Java open source project
➔ 800 commits
Extracting data from MetricMiner query interface:
➔ 256 Java projects from Apache
➔ 500k commits

10. Next steps
➔ Improve user interface
➔ Improve scalability - maybe moving to Google
BigQuery
➔ Gather more data!

11. Thanks!
