Leveraging linked data in Social Event Detection.
Timo Hintsa, Sari Vainikainen, Magnus Melin · 2011
In this paper, we present our approach and results for the MediaEval 2011 Social Event detection task. VTT participated in Challenge 2 where a given dataset of Flickr photos were matched to events in certain places. We used Linked Data to enhance the dataset by adding event information and other related data and then searching the enhanced dataset. Additional information relating to venues and places were used for creating a subset of photos for each place; Barcelona and Amsterdam. The event profiles including semantically enhanced metadata were used in media retrieval. The approach of combining additional data from the Internet and limiting the queries to limited subsets improved the relevance of photos relating to the events.
