| The CHOICE project seeks to chart the uncharted information landscape, focusing on semi-automatic semantic annotation and employing context information. Semantic annotation involves the annotation of archived objects, such as video, images and books with semantic categories from some standardized metadata repository, such as domain thesauri and ontologies. The use of semantic annotation allows one to widen the search facilities in a collection. The driving use case of this project is the Sound and Vision video archive. The objective is 1) to show how semantic annotation can be supported in the archiving process by exploiting the available context information and 2) to show how these annotations can subsequently be used to improve search facilities. Context information is information that provides peripheral insights into an object; how it was perceived, how it was created, how it relates to other objects made during the same era and so on. At the moment automatic techniques for video analysis are still of limited value for the derivation of semantic categories. On the other hand, manual semantic annotation is time-consuming. |
