Efficient media search applications can highly improve productivity in various domains. This is also the case in a broadcast environment, where large amounts of media are generated and archived. In this paper, we show how connecting a keyword thesaurus, used to annotate archived media items at the Flemish public service broadcaster in Belgium, with the Linked Open Data (LOD) cloud can greatly improve search applications. First, an algorithm is described that is used to automatically link concepts defined in a thesaurus with DBpedia, an important linking hub in the LOD cloud. The evaluation of this algorithm gives an overall accuracy of 81.64%. This is followed by an overview of features that are useful in a search application that were enabled through establishing a connection with the LOD cloud.
