Beitrag zu Handlungsfeldern

Nachfolgend ist die Zuordnung des Moduls zu den Handlungsfeldern des Studiengangs aufgeführt, und zwar als anteiliger Beitrag (als ECTS und inhaltlich). Dies gibt auch Auskunft über die Verwendbarkeit des Moduls in anderen Studiengängen und über die Beziehung zu anderen Modulen im selben Studiengang.

Learning Outcome

Students learn about the usecase and dimension of web search with a special focus on scientific and academic use cases. After a brief introduction (or a recap) on Information Retrieval and search engine technologies this courses dives into current state-of-the-art

To understand the issues related to academic search like domain-specific languages, expertise and entities, they implement their own search environment to foster their knowledge and hands-on experiences with the latest Information Retrieval approaches in the field. At the end of the course they know about the issues and solutions that are implemented in big academic search systems like GoogleScholar, PubMed, or arXiv and how the knowledge can be transfered to other domains like enterprise search or expertise retrieval. In this process they will analyze and evaluate these search systems to discover and explain differences.

With the knowledge aquired in this course students are able to apply existing search solutions to commercial or research-related search problems and in a later stage design their own search systems and use state-of-the-art IR methods to expand their knowledge on data sets like web corpora, user logs, or large-scale academic data sets.

Lehr- und Lernformen

The course follows a hybrid format, where lecture videos are provided online and classroom time is used for discussion, exercises, and working on assignments.

• This course involves self-study (which can be completed online): You’re expected to watch the lecture videos, read the corresponding book chapters/sections listed on the last slide of each lecture deck, as well as complete the exercises on GitHub.
• There is also a classroom component which is not obligatory, but highly recommended for an optimal learning experience. This involves discussion and exercises in a regular or virtual classroom setting.

Zur Verfügung gestelltes Lehrmaterial

• slides and recorded lectures
• excersises
