Who We Are

& What We Do

Information retrieval (IR) is the activity of obtaining information resources relevant to an information need. The best-known IR use case are search engines - the most prominent one of course is Google. The Information Retrieval Research Group at Technische Hochschule Köln (University of Applied Sciences) is doing research and development in the fields of retrieval evaluation, digital libraries, query suggestions and bibliometrics enhanced retrieval methods.


We are happy to annouce that DFG - German Research Foundation has accepted our grant application for the STELLA project (Infrastructure for Living Labs). Together with our partner of GESIS and ZB MED we will build up a new evaluation environment for retrieval and recommender systems. These online evaluation will will differ considerably from classical TREC studies and will enable researchers to use an evaluation method that was previously reserved only for industrial research.

NEWSWelcome, Malte!

We would like to welcome our new colleague Malte Bonart who joined us last week. He is going to work in the Esupol project and will research the influence of search engines on political opinion formation.
