Topic Detection and Trend Analysis Methods using Wikidata

In the media sector, AI-based methods are increasingly being used to semantically analyze and enrich large amounts of structured and unstructured content with the help of trained language models and external, general knowledge sources such as Wikidata. Thus, previously unknown information like persons, organizations, events, geographical locations, media or thematic concepts can be identified. New methods, some of which have been derived from well-established scientific data analysis methods (DBSCAN), provide more accurate and flexible classifications and enable automatic recognition of temporal changes in topic weighting.
