Selection of Concept Detectors for Video Search by Ontology-Enriched Semantic Spaces

  title={Selection of Concept Detectors for Video Search by Ontology-Enriched Semantic Spaces},
  author={Xiao-Yong Wei and Chong-Wah Ngo and Yu-Gang Jiang},
  journal={IEEE Transactions on Multimedia},
This paper describes the construction and utilization of two novel semantic spaces, namely ontology-enriched semantic space (OSS) and ontology-enriched orthogonal semantic space (OS2), to facilitate the selection of concept detectors for video search. These two semantic spaces are enriched with ontology knowledge, while emphasizing consistent and uniform comparison of ontological relatedness among concepts for query-to-concept mapping. OS2, in addition to being a linear space like OSS, also… CONTINUE READING
