Movie test provides information about viewing experiences
The Language and Audio Technology team of MediaTeam and researchers from the Department of Information Studies have examined, how semantic gaps can be filled in the retrieval of sound and video recordings in various databases. The research funded by the Academy of Finland has focused on how information contained in movies can be utilised in content-based retrieval. Special attention has been paid on what people remember about movies and what elements contained in films can be searched on a computer basis.
Once the above-mentioned information has been accessed, content-based retrieval becomes remarkably more efficient. One goal in the research is to narrow down the gap between information contained in movies and the mental models of a person conducting the search. Film clips and trailers have been utilised as research material in the earlier phases of the three-part test series. The mental images and recollections evoked by viewing the whole film are studied on the basis of these clips.
The results from the first two phases are utilised in the third and final phase, in which the selected research material is an entire movie. Test participants watched the movie in the Star movie theatre in Oulu. The test results are applied in the development of search systems, which is being done also in MediaTeam’s Vikings project. A total of about 20 people took part in the movie test, and some of them are more intensely committed to watching films as a hobby.
