Digitalisation is shaping a new consumption era characterised by high connectivity, mobility and a broad range of easily accessible information on products, prices and alternatives. As a result, it becomes more difficult than ever to understand modern consumers along their complex and dynamic path to purchase. However, mobile data about consumers’ behaviour captured on their phone has high potential for facing this challenge. Yet, there is no solution on how to use this data to follow the consumers on their mobile devices. This thesis proposes a first approach on how mobile data collected with smartphone sensing technology can be analysed to assess mobile consumer behaviour along their customer journey. Based on current practices in customer journey analytics, a mobile customer journey model is developed and three analysis concepts are created, which are implemented in an explorative analysis. The results show that mobile sensing data presents a great opportunity for analysing mobile behaviour in three main research areas: examining the touchpoint performance of a brand across mobile apps, describing different target groups by their smartphone usage behaviour and deriving real customer journeys on users’ devices. Nonetheless, further exploration is necessary to unlock the full potential of mobile data in customer journey analytics.
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 technology advances, the services offered by libraries and the roles of
librarians continue being reconsidered. This paper describes the traditional
model and development of liaison and embedded librarians, examines the
online visibility of liaison librarians and their services in an embedded sense,
especially regarding instruction, of selected Canadian Academic Libraries, and
provides a short view to German libraries and their subject librarians.
It has been shown that even if not clearly a development of liaison librarians to
certain embedment is emphasized for each library, it at least evolves to a usercentered
approach and a preference to stronger collaborations. The selected
libraries seek to broaden their scope of partnerships. In which deepness it is
realized, lastly depends on the willingness of both participators and capacities.
Libraries have stated their flexibility in various ways and are ready to step in at
the point of need. The one closest to embedded services is the instruction of
information literacy as its effectiveness requests a longer relationship in order to
flourish. Nevertheless research support in Health Sciences obviously has
become an integral part.

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.
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.
In recent years, access to and curation of research data have become a topic of discussion in national and international think tanks and advisory groups. There are various concepts and suggestions to stimulate and improve competences in dealing with research data. In addition, semantic web technologies and Linked Open Data are raising the awareness for access to data and environments in which data can be processed, retrieved, reused and preserved. Competences in dealing with these challenges will extend the scope of work and the tasks not only of researchers but of librarians as well. In the context of a survey on digital preservation of research data in Germany, research data-related tasks have been identified and consequences for the scope of library activities and qualification needs of librarians have been suggested. Competences in collecting, describing, and processing domain-related data in connection with other activities in digital curation of research data gain in importance. LIS (Library and Information Science) curricula should cover these extended qualification needs.
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.
