Information Engineering

We Derive Value from Data and Information

These are but a few of the questions that the Information Engineering (IE) group is working to answer. While the “data and information flood” is often discussed negatively, we see a great opportunity to leverage data and information using the right approaches – both at search-time, as well as during analysis.

The group transfers insights derived from research and development into teaching for students of the computer science curricula. It offers modules such as “Information Engineering 1 (Information Retrieval)”, “Information Engineering 2 (Data Warehousing & Big Data)”, “Artificial Intelligence 1”, “Artificial Intelligence 2”, and “Machine Learning”. The group is active in both national and international research projects of the EU framework programs.

Research Topics

The group is concerned with fundamental sub-disciplines of the field Data Science and is founding member of ZHAW Datalab.

Information Retrieval

Information Retrieval (IR) is concerned with all facets of search relating to unstructured and semi-structured data. In particular, aspects from related Natural Language Processing sub-disciplines intersect with IR, leading to research areas such as cross-language retrieval. Further topics include multimedia retrieval, categorization, recommender services, question answering and topic/trend/event detection.

Databases and Information Systems

Databases, information systems and data warehousing are a range of areas that focus on processing of structured data/information and Big Data. Interesting aspects include efficient storage, administration and querying of this data, with the goal of supporting decision-making processes. A key line of investigation centres on the construction of natural-language interfaces to databases, thus enabling a natural, “human” dialog with such systems. Other topics include the application of machine learning algorithms to data management problems such as query optimization or data fusion.

Artificial Intelligence

Artificial Intelligence and Machine Learning are concerned with the design and analysis of smart systems through the use of machine learning methods, notably deep learning and reinforcement learning approaches. An important focus area is the successful handling of pattern recognition problems, e.g. in areas such as predictive maintenance, document analysis, object classification and detection in computer vision or speaker recognition. A common research thread across these diverse problem areas is the investigation of applicability and robustness of algorithms across different scales of data, as well as the interpretability of results.
