Data Science Zookeeper



Hi,
I’m Nico!

My interests center around information systems engineering and data analytics in times of digital transformation. I have extensive experience in application-oriented computer science research and IT consulting projects. I currently work as a Professor for Information Systems and AI in Germany.

The sunburst diagram1 below is a visualization of the distribution of topics in the abstracts of my works (corpus). Basis is the result of a Latent Dirichlet Allocation (LDA)2. The data has been cleaned using the Python library NLTK3 before using the Python library gensim4 to build the LDA model.
The sunburst visualization is created with D3.js5 building on works by Mike Bostock6 and Vasco Asturiano7.

2. Hosting and server logs

When this website is accessed, the hosting provider processes technical connection data required to deliver and secure the website. This may include the IP address, date and time, requested resource, referrer, browser information, transferred data volume, and response status.

Processing is based on Article 6(1)(f) GDPR. The legitimate interest is secure, reliable, and efficient website delivery. The hosting provider receives this data as a service provider. Routine log data is deleted when no longer required for these purposes. Security-related data may be retained until an incident has been resolved or a legal retention obligation expires.

3. No analytics, advertising, or tracking

This website does not use analytics services, advertising networks, tracking pixels, or comparable tracking technologies. The website operator does not set cookies and does not store information in the visitor’s browser. No consent banner is therefore displayed.

4. Local fonts and resources

Source Sans 3 and all technical resources required to display this website are served locally from the same host. Loading the website does not contact Adobe Fonts, Google Fonts, or another font provider.

5. External links

External services are not contacted automatically. If a visitor follows an external link, the destination provider processes the resulting connection data under its own responsibility.

6. Email contact

When a visitor contacts the controller by email, submitted data is processed to handle the request. Depending on the request, processing is based on Article 6(1)(b) or Article 6(1)(f) GDPR. Correspondence is deleted when no longer required, unless legal retention obligations apply.

7. Rights

Data subjects may request access, rectification, erasure, restriction of processing, data portability where applicable, or object to processing based on legitimate interests. They may also lodge a complaint with a competent data protection supervisory authority.
