In this paper a new approach to metadata production is presented. For this purpose, a new interactive tool for audiovisual content acquisition and classication has been developed. The user can decompose a given content into units and easily annotate each unit adding basic information such as time, place, etc. as well classication information such as event type, relationship type, etc. according to the MPEG 7 Standard. At the end of this production process, the tool automatically produces a structural description of the overall set of the annotated units. The new idea proposed in this work is to combine the intrinsic semantics of each annotated unit with the implicit semantic information derived from the structural description, hence reducing the needs to perform complex signal processing operations on the content. This aspect is really important since image and video processing is generally heavier than metadata processing and the content can be spread over a network and not made readily available at the processing point.

Abstract
In this paper a new approach to metadata production is presented. For this purpose, a new interactive tool for audiovisual content acquisition and classication has been developed. The user can decompose a given content into units and easily annotate each unit adding basic information such as time, place, etc. as well classication information such as event type, relationship type, etc. according to the MPEG 7 Standard. At the end of this production process, the tool automatically produces a structural description of the overall set of the annotated units. The new idea proposed in this work is to combine the intrinsic semantics of each annotated unit with the implicit semantic information derived from the structural description, hence reducing the needs to perform complex signal processing operations on the content. This aspect is really important since image and video processing is generally heavier than metadata processing and the content can be spread over a network and not made readily available at the processing point.File | Dimensione | Formato | |
