Search engine for semantically similar press releases

Informationsdienst Wissenschaft

Together with the ‘German Research Centre for Artificial Intelligence’ (DFKI) idw has developed, tested, and launched a semantic search engine. The system has been available to all idw users since 12.01.2022. The search engine considers the complete content of a press release or an expert query, finds the semantically most similar idw news and displays the top five hits.

This works even if the connecting topic - for example climate change or pandemic - does not appear as a term in the texts. The system, initiated with the DFKI's Corporate Communications Department, uses the ‘Generalised Semantics Retrieval Engine’ (GSRE) developed by Prof. Günter Neumann (DFKI) of his research group QAIE (Question Answering and Information Extraction). GSRE identifies and evaluates the semantic similarity of documents.

The idw initially uses the prototype in the expert search and offers further idw press releases as additional research material to idw's journalists. In addition, idw uses the search engine to display the five semantically most similar idw news in the detailed view of each press release on the idw-online page. Thus all idw users receive further relevant news with just one click. After testing the service, idw is planning further areas of use for the semantic search engine.

Combination of search terms

You can combine search terms with and, or and/or not, e.g. Philo not logy.


You can use brackets to separate combinations from each other, e.g. (Philo not logy) or (Psycho and logy).


Coherent groups of words will be located as complete phrases if you put them into quotation marks, e.g. “Federal Republic of Germany”.

Selection criteria

You can also use the advanced search without entering search terms. It will then follow the criteria you have selected (e.g. country or subject area).

If you have not selected any criteria in a given category, the entire category will be searched (e.g. all subject areas or all countries).
