Data Visualisation and Analytics

May 25th, 2023 | by

This course provides participants with a comprehensive and versatile toolbox of data visualisation and analysis methods, which can be transferred to a vast number of applications.

Seminar Privacy and Big Data

May 24th, 2023 | by

This seminar is about new and emerging approaches to adjust and balance privacy and utility in data intensive applications, such as information retrieval, data mining and personalisation. These new approaches have the potential to enable a new generation of privacy-enabled services which are not focused on maximizing the collection of user data. Instead these new approaches enable user privacy under different threat models, such as protecting the identity of individual users when querying aggregated data, or preventing leakage of query patterns when users retrieve data from a database. As a result, these new approaches may help businesses in their compliance with increasingly regulatory trust and reinforce user trust, while enabling new business models at the same time.

Knowledge Graph Lab WS 2023

May 24th, 2023 | by

Knowledge Graphs are large graphs used to capture information about the real world in such a way that is is useful for applications. In these data structures, there are all sorts of entities (for example, people, events, places, organizations, etc.). Knowledge Graphs are used by many organizations to represent the information they need for their operations. The most well-known example is Google, where a knowledge graph is used to enrich the search results. Also personal assistants, such as Amazon’s Alexa, Apple’s Siri and Google Now, as well as question answering systems such as IBM Watson, make use of knowledge graphs to provide information to their users.

Besides these, also other information graphs, are in use by large organizations to improve or personalize their services. Examples include the Facebook graph, the Amazon product graph, and the Thompson Reuters Knowledge Graph.

Opensource Knowledge Graphs such as Wikidata and DBPedia provide universal access to linked entities from a large range of domains.

The graph also contains all sorts of information about these entities (e.g., age, opening hours, …) and relations between them (e.g., “this shop is located in Aachen”). Furthermore, it may contain context information (e.g., the source of some information) and schema information or background knowledge (e.g., “shops have opening hours”).

In this course we will give a basic practical introduction to working with these graphs. We plan to cover the following in the course:

  • Graph representation of data
  • Knowledge Graph basics
  • Knowledge Graph creation and maintainance tasks: Creation, Hosting, Curation and Deployment
  • Use of vocabularies and ontologies as schemas for graphs
  • Searching information in knowledge graphs
  • Information extraction into knowledge graphs
  • Data mining techniques for knowledge graphs
  • Knowledge graph completion (predicting links, finding anomalies)
  • Data governance aspects, e.g., data quality
  • Architectures for knowledge graphs (e.g., data lakes, central vs. decentral storage, knowledge graphs on top of relational or NoSQL databases)

Mixed Reality Lab

May 22nd, 2023 | by

Mixed Reality is a continuum of spatial computing experiences on virtual, augmented and extended reality devices, such as the Microsoft HoloLens 2, the HTC Vive Pro, Meta Quest 2 and Android smartphones. In this lab, we learn the basics of mixed reality software development in independent project work that student groups can propose and elaborate.

Social Computing Seminar

May 22nd, 2023 | by

Social Computing embodies the intricate interplay between evolving computational systems and dynamic societal behaviors. This field examines how technology can be crafted to interpret and enhance human interactions and observes these systems’ transformative influence on our social fabric.

Datenbanken und Informationssysteme

March 27th, 2023 | by

Die Vorlesung “Datenbanken und Informationssysteme” gibt einen einführenden Überblick über Datenbanken und ihre Verwendung in Informationssystemen.

Data Stream Management and Analysis

March 17th, 2023 | by

In many fields today data is produced continuously, potentially unbounded, and at high rates, which is termed as data stream. Applications in smart manufacturing, aerospace,  particle physics, or stock exchange trading have a high demand to handle and analyze the massive data streams created. Due to their challenging characteristics specific technologies and methods for data management and analysis have been developed. In this course, you will get a deep understanding of these principles and techniques, such as query processing and optimization or data stream mining.

Seminar Computational Biomedicine

February 13th, 2023 | by

Integration of machine learning with medical data analysis is an essential block in the process of finding patient biomarkers used for clinical studies with a vision to improve cancer treatments. One such example is the application of personalized medicine, being one of the cornerstones for improving cancer patient care. In this Seminar, we will focus on the algorithmic and machine learning aspects of handling high throughput and high dimensional molecular data in the field of computation biomedicine.

Data Science in Medicine

January 26th, 2023 | by

Health data analytics is one of the main drivers for the future of medicine. Various sources of big data, including patient records, diagnostic images, genomic data, wearable sensors, are being generated in our everyday life by health care practitioners, researchers, and patients themselves. Data science aims to identify patterns, discovering the underlying cause of diseases and well being by analyzing this data.

Mixed Reality Lab

December 15th, 2022 | by

Mixed Reality is a continuum of spatial computing experiences on virtual, augmented and extended reality devices, such as the Microsoft HoloLens, the HTC Vive, and mobile phones. In this lab, we learn the basics of mixed reality software development in hands-on lessons with practical tasks. The lab contains a small independent project student groups can propose and work on.
