CALIMERA: Conference Advanced Level Information ManagEment & RetrievAl
The amount of recorded talks in conferences and particularly scientific ones is rapidly increasing. However, the resulting multimedia data, such as videos, lack of rich and semantic content indexing. Therefore, finding the appropriate video of a recorded talk in the increasing amount of information becomes a complex task. Based on these observations CALIMERA work consists of developing an integrated framework for content and context based video retrieval. CALIMERA proposes a novel approach that takes into account the context of a conference (logistics, conference thematic, related documents, participants, etc.) and the content of the video recording of a talk. This enables to enhance the indexing of such video, and thus its retrieval. CALIMERA is based on HELO, an integrated conference ontology that models the Conference Integrated Information.
