Creating and Analyzing Source Code Repository Models – A Model-based Approach to Mining Software Repositories

Abstract—With mining software repositories (MSR), we analyze the rich data created during the whole evolution of one or more software projects. One major obstacle in MSR is the heterogeneity and complexity of source code as a data source. With model-based … Continue reading

Evaluation of Model Comparison for Delta-Compression in Model Persistence

Abstract—Model-based software engineering is applied to more and more complex software systems. As a result, larger and larger mod- els with longer and longer histories have to be maintained and per- sisted. Already, a lot of research efforts went into … Continue reading

Generation of Random Software Models for Benchmarks

Abstract—Since model driven engineering (MDE) is applied to larger and more complex system, the memory and execution time performance of model processing tools and frameworks has become important. Benchmarks are a valuable tool to evaluate performance and hence assess scalability. … Continue reading

Model-Based Mining of Source Code Repositories

Abstract—The Mining Software Repositories (MSR) field analyzes the rich data available in source code repositories (SCR) to uncover interesting and actionable information about software system evolution. Major obstacles in MSR are the heterogeneity of software projects and the amount of data that … Continue reading

SrcRepo: A model-based framework for analyzing large scale software repositories

This is a brief introduction to a new research subject that I recently started working on. It serves as a case-study for very large EMF models and applying big data techniques to EMF, which is my current research subject. I … Continue reading

EMF Modeling in Traffic Surveillance Experiments

Abstract—We use a wireless sensor network equipped with acceleration sensors to measure seismic waves caused by rolling traffic. In this paper, we report on our experiences in applying an EMF-based data infrastructure to these experiments. We built an experimentation infrastructure … Continue reading

Automated and Transparent Model Fragmentation for Persisting Large Models

Abstract—It is hard to experiment with test-beds for communi- cation networks: data produced in the network has to be retrieved and analyzed, networks must be reconfigured before and between experiments, data is often little structured (log-files) and analysis methods and … Continue reading
