Abstract
An approach for implementing affective information as tags for multimedia content indexing and retrieval is presented. The approach can be used for implicit as well as explicit tags and is presented here using data recorded during the viewing of movie fragments containing annotations and physiological signal recordings. For retrieval based on affective queries, a representation of the query-words is defined in the arousal-valence space in the form of a Gaussian probability distribution and a retrieval method based on this representation is presented. Validation of retrieval accuracy is performed using Precision and Recall parameters. Results show that the use of arousal and valence as affective tags can improve retrieval results.
