In this paper we present the second participation of the NLP&IR group at UNED in the MediaEval Genre Tagging Task. This categorization task was carried out applying an Information Retrieval (IR) approach considering the video collection’s textual data and query expansion techniques. The results show that the combination of social tags and language models is useful to perform query expansion.
