Research data which is put into long term storage needs to have quality metadata attached so it may be found in the future. Metadata facilitates the reuse of data by third parties and makes it citable in new research contexts and for new research questions. However, better tools are needed to help the researchers add metadata and prepare their data for publication. These tools should integrate well in the existing research workflow of the scientists, to allow metadata enrichment even while they are creating, gathering or collecting the data. In this thesis an existing data publication tool from the project DARIAH-DE was connected to a proven file synchronization software to allow the researchers prepare the data from their personal computers and mobile devices and make it ready for publication. The goal of this thesis was to find out whether the use of file synchronization software eases the data publication process for the researchers.
As a key part of human-computer interaction(HCI) and usability testing, the capturing and recording of key user interaction plays a center role for ensuring a reliable post-hoc analysis of collected user interaction data, thus improving the odds of insightful HCI and usability testing cycles for use cases such as the evaluation of interactive information retrieval Systems(IRR). As such, the practice of logging is of significant importance for multiple fields of study such as IIR, HCI and most recently also Living Lab approaches. Living lab approaches represent a user-centered research methodology with a focus on user involvement, experimental approaches and extensive collaboration for the sake of co-production of knowledge and as such, has a dire need for robust and easy to use logging solutions.
With past logging solutions being either expensive, hard to use or error-prone, recent conferences gave rise to new logging solutions using contemporary web technologies, which aim to improve the logging landscape within the research community. Over the course of this paper, two of these recent logging solutions, LogUI and Big Brother, are to be inspected for their key features and then evaluated, whether they are suitable logging solutions for living lab and IIR environments. Results and research indicate, that both logging solutions offer significant benefits for research using living lab and IIR approaches, with LogUI embracing many of the experimental paradigms that guide the living lab approach.
With the growing scientific output that is produced, its getting more important to automate the extraction of knowledge from articles. This bachelor thesis will describe an approach doing exactly this. Scientific articles will be obtained from a database.
These articles will be preprocessed to gain a set of training data, to update a language model that already exists for Python library spaCy. The model will be trained to recognize different sorts of entities regarding to the virus rabies. After this process the model will be used for ten articles and the extracted knowledge will be used to extend the Open Research Knowledge Graph.
Digital curation is currently not very well covered by university curricula in the German speaking countries. Nevertheless there is a strong demand for well-educated staff in this field. As part of the project “nestor”, a transnational partnership of academic institutions in Germany, Switzerland, and Austria, a comprehensive qualification program based on e-learning tutorials, schools, seminars, and publications has been established to meet this demand.
Analysing the systematics of search engine autocompletion functions by means of data mining methods
(2017)
In the internet era, the information that can be found about politicians online can influence
events such as the results of elections. Research has shown that biased search rankings can
shift the voting preferences of undecided voters. This shows the importance of studying
online search behaviour, especially in the pre-elections phase, when search results can
have a particular influence on the future political scene of a country.
This master thesis aimed to study the behaviour of online search engines in a period before
the German federal election in 2017. The aim was to ascertain if there is any pattern to be
found in the auto-suggestions for searches related to politicians.
In order to gather data for this experiment, a crawler browsed search engine web pages,
input a name and a surname of a politician, and saved that together with all autosuggestions
from the search engine. The autosuggestions were prepared for the analysis and
divided into semantic groups with the help of clustering algorithms.
Different statistical methods, such as correlation analysis, regression analysis, and clustering
were used to identify patterns in the data. The research showed that there are
no particularly strong patterns in the autosuggestions for searches related to politician’s
names. Only moderate dependence was found between gender and personal topics, and
showed that a higher amount of personal information autosuggestions correspond more
to female politicians.

As a result of the widespread use of online networking sites, the ways in which people connect and network, both personally and professionally, have been transformed in recent years. Platforms such as LinkedIn or XING have profoundly changed the dynamics of professional networking by providing new means of contact and creating an environment that promotes the exchange of knowledge and ideas. However, compared to social network sites, professional network sites have received little attention in research despite their growing importance. Particularly, the relationship between the use of professional network sites and users' well-being has been understudied. However, the investigation of these platforms is of societal relevance given their consistent growth and the increasing importance of these platforms for both individuals and companies. Existing research on the relationship between the use of social network sites (SNS) and the subjective well-being of users has identified the usage type (active and passive use) as a relevant variable. The aim of this study was to transfer these findings to the context of professional network sites and to explore the relationship between the type of use of a professional network site and the subjective well-being of its users.For this purpose, the active-passive model of SNS use was applied to the context of professional network sites for the first time. To answer the research question, a quantitative online survey was conducted with 526 LinkedIn users. Results of the mediation analyses revealed an indirect positive relation between active use of LinkedIn and well-being. Conversely, a negative indirect relation was found between passive use of LinkedIn and subjective well-being. All tested mediating variables, including social capital for active use and upward social comparison, downward social comparison and envy for passive use, were determined to be relevant in explaining the link between well-being and active and passive LinkedIn use, respectively.
In the last few years the issue of curation of research data has become a topic of enhanced interest in scientific communities. But there is no clear understanding of how to deal with curation of research data. Regarding the situation in Germany, there was no clear picture of the methods that different academic disciplines use to preserve and curate their research data. Even more there was no clear understanding and consensus which role libraries could or should play in this issue. A baseline study was conducted in cooperation with nestor and the D-Grid GmbH in Germany. The study gives more stable data to scientists, service infrastructure experts and politicians to foster strategic concepts for digital curation and preservation in and between the disciplines. The survey addressed eleven disciplines including the humanities, social sciences, psycholinguistics, pedagogics, classical studies, geoscience, climate research, biodiversity, particle physics, astronomy and medicine. Results can be seen as more or less representative for the situation in Germany. Findings show that libraries and data centers are involved but there is no clear result on the role libraries should or will play in the field. Libraries which are in close connection to scientists have an advantage in being addressed as institutions responsible for digital curation and preservation. Librarian’s competences regarding research data still have to be proofed. Nevertheless individual scientists and research data centers might need librarian´s expertise regarding the application of metadata standards and the provision of services in connection with the research data curated by institutions. Qualification and training regarding curation of research data is still at its beginning and should be addressed by programs of universities.

Several cultural heritage institutions all around the world have set up special services, trainings, courses or programs focusing on curation of digital material. Digital curation is a multifaceted task with a great variety of responsibilities, preconditions and objectives. For the first time in this field the DigCurV project offers a framework to locate competences and skills related to vocational education and training regarding digital curation processes. Referring to this framework should be a good starting point for differentiated educational activities focusing on special target groups, their educational background, the objectives of the digital curation process, and the material which has to be curated. Based on this, additional frameworks comprising these educational activities can be set up – still referring to the DigCurV framework partially or in total. This will offer the opportunity to compare educational activities regarding content and the results achieved. Beside these efforts regarding content and concepts of digital curation education there is another ongoing challenge: getting people involved and making them eager to curate (their) digital material properly. The curation job is hardly glamorous or much admired. For the most part it is a service-oriented back office activity demanding functionality and perfection. For a long time, specialists will be needed – and will need qualified training – to meet these requirements. Increasing awareness of the need for digital curation by professionals and the public offers opportunities to get digital curation professionals and their skills involved even in everyone’s working environment.
