42017-04-2512:15Johannes PfannThesis DefenseMeasuring the patch review process in open and inner sourceInner-Source-Entwicklung ist die Anwendung von Open-Source-Praktiken in Unternehmensstrukturen. Eine Praktik wird Review-Prozess bezeichnet. Dieser Prozess trennt den Codebeitrag von dessen Integration. In Inner Source ist der Review-Prozess nicht erforscht.
Daher wird für Forschungszwecke eine geeignete Software zum Messen dieses Prozesses benötigt. Die bisher eingesetzten Messinstrumente für Inner-Source-Entwicklung sind nicht in der Lage den Review-Prozess zu untersuchen.
Die Arbeit beschäftigt sich mit der Erweiterung einer bestehenden Anwendung um Informationen über die Review-Prozesse in Inner Source zu erfassen.
Um die Funktionalität dieser Erweiterung zu evaluieren, wird diese auf ausgewählten Projekten angewendet. Mit den gesammelten Daten wird demonstriert, dass diese zur Beantwortung typischer Fragestellungen geeignet sind.
Die Erweiterung ermöglicht für weitere Forschungen die Messung der Review-Prozesse in Inner-Source-Projekten

92017-05-3012:15Oliver LutzThesis Defense Tree-based, Semantic Article Difference VisualizationThe platform, Sweble Hub allows to collaboratively edit Wiki-content using the Wiki Object Model. This is, however, not carried out on wikitext level as is normally the case, but rather by using the principle, ‘what you see is what you get’.
The objective is to extend the existing project with a clearly displayed article difference visualization which provides a comprehensible overview of modifications made.
This bachelor thesis offers a solution as to how wikitext-file versions can be clearly compared. Based on tree-based algorithms and data structures, it allows to interpret the semantics of wikitext documents and any changes made within these documents. As a result it provides a more detailed depiction in comparison to text-based Diffs. The outcome is embedded into the Sweble Hub application.

102017-06-0612:15Martin HofmannThesis DefenseText Mining for Relationship ExtractionCurrently, Qualitative Data Analysis methods are based on manual coding of
texts.
The coding process requires large amounts of labor and is prone to human error.
This is especially a problem for domain analysis where a large amount of
qualitative data has to be analyzed.
We present a relationship extraction approach based on Natural Language Processing
for this purpose. It automates the extraction of relationships between
codes that were provided by the coder. This speeds up the analysis process and
helps to uncover relationships the human coder might have missed.
Our method produces a graphical overview of relationships that were found to
exist between codes. It is evaluated by comparison with previously generated
models from existing Qualitative Data Analysis projects.

112017-06-1312:15Gabriel BauerThesis DefenseIntegration of a Refactoring UI into the Sweble Hub SoftwareIn programming languages refactorings are a well-established tool that allows developers to consistently apply changes to the codebase. We have brought this technology to wikis, specifically to articles written in wikitext, the markup language behind Wikipedia. The goal of this thesis is to implement a refactoring UI on top of a visual editor that guides authors through the process of applying a refactoring or transformation to the wiki as a whole.

12:15Andreas BauerThesis DefenseManaging Org. Data for Patch-Flow MeasurementWerden Open Source Praktiken und die Etablierung einer Open Source
ähnlichen Kultur innerhalb einer Organisation angewendet, so wird dies
auch als Inner Source (IS) bezeichnet. Die bestehende Software
Collaboration Metric Suite (CMSuite) stellt Metriken für die
Zusammenarbeit zwischen Softwareprojekten bereit. Anhand dieser
Metriken kann die Anwendung von IS in Organisationen validiert werden.

Das der CMSuite zugrunde liegende Datenmodell unterstützt derzeit aber
nur einfache hierarchische Organisationsstrukturen. Organisationsformen
mit einem komplexeren Aufbau können somit nicht korrekt abgebildet
werden. In dieser Arbeit wird ein Organisationsmodell konzipiert und in
die CMSuite integriert. Dieses Datenmodell wird den Anforderungen an
eine komplexe Organisationsstruktur gerecht. Hierzu werden unter
anderem zwei durchgeführte Fallstudien, welche die Schwächen des
gegenwärtigen Datenmodells aufzeigen, analysiert.

Zum Schluss wird gezeigt, dass der Umgang mit komplexen
Organisationsstrukturen, die der Unternehmenspraxis entsprechen, für
die CMSuite kein Problem mehr darstellt

142017-07-0412:15Jan WeißThesis DefenseTowards a Continuous Delivery Workflow for the Sweble Hub SoftwareWithin the scope of this master thesis a Continuous Deployment workflow for the Sweble Hub software system, which is under development at the professorship of Open Source Software, was designed and adapted. The implementation of the Deployment Pipeline follows the best practices of Continuous Delivery and will be introduced at the architecture and design chapter of this thesis. In addition this thesis contains the dissociation of Continuous Integration, Continuous Delivery and Continuous Deployment.
The Deployment Pipeline consists of different stages to fullfill all requirements to the Continuous Deployment process and seperates it in logical blocks. As result a process is expected which executes all steps in the pipeline from building to deployment in production completly automated.
Furthermore it takes the nature of a microservice architecture into account and introduces some concepts for deploying and for monitoring microservices. The realization of this concepts is shown by example in the implementation of the monitor and deploy service which is also part of this thesis.
