Final Thesis: A Visual UML-Editor for QDAcity
Abstract: QDAcity ist eine Webanwendung zur Unterstützung der qualitativen Datenanalyse (QDA) von Text-Daten. Bei der qualitativen Datenanalyse geht es darum Informationen und Zusammenhänge aus unstrukturierten Daten wie Interviewtranskriptionen zu gewinnen. Ein wichtiger Prozess bei der QDA ist die Kodierung, bei der Textstellen mit selbstdefinierten Codes versehen werden, um die Inhalte besser zu strukturieren. Die Anwendung QDAcity […]Abstract: QDAcity ist eine Webanwendung zur Unterstützung der qualitativen Datenanalyse (QDA) von Text-Daten.

Final Thesis: QDAcity Quality Metrics
Abstract: The cloud-based QDAcity platform allows to conduct collaborative research projects applying Qualitative Data Analysis methods and research validation through crowdsourcing. When using Qualitative Data Analysis as a research method, expressive measurements of the quality and maturity of the results are essential to prove the validity of the research Findings. Common measures for validity of ratings […]Abstract: The cloud-based QDAcity platform allows to conduct collaborative research projects applying Qualitative Data Analysis methods and research validation through crowdsourcing.

Final Thesis: Text Mining for Relationship Extraction
Abstract: Qualitative Data Analysis (QDA) methods are based on manual coding of texts. To extract a domain model from a text corpus using QDA, information has to be extracted and compiled into the domain model by hand. This is especially a problem for cases where large amounts of data have to be analyzed. For this purpose, […]

Final Thesis: A Metamodel for Code Systems
Abstract: Requirements elicitation is an important factor in software engineering. Mainly the information needed is elicited through interviews and other qualitative sources. The analysis that follows is often an ad-hoc process that relies on expertise of the analyst(s) and therefore is hardly replicable. Additionally, the process is not transparent as the resulting modeling elements cannot be […]Abstract: Requirements elicitation is an important factor in software engineering.

Final Thesis: Validating Requirements Specification Using Surveys
Abstract: The quality of the software requirements is vital to a project’s success, and the means of assessing the software requirements specifications quality are of high importance. This thesis presents a novel method of validation large requirements specifications using surveys. We developed a detailed method description, sketching a draft at the beginning of the research and […]

Technical Report: Using Students as a Distributed Coding Team for Validation through Intercoder Agreement
Abstract: In qualitative research, results often emerge through an analysis process called coding. A common measure of validity of theories built through qualitative research is the agreement between different people coding the same materials. High intercoder agreement indicates that the findings are derived from the data as opposed to being relative results based on the […]
