Requirements Analysis of Cross-media Knowledge Acquisition, Deliverable D 8.1

This document presents the requirements for Cross-Media Knowledge Acquisition in the context of the X-Media project. The need for cross-media methods is motivated using both general examples and examples derived from the industrial partners’ use cases. Furthermore, the several types of possible approaches to the problem are introduced. Requirements identified include exploiting available background knowledge, coping with large-scale, supporting output of uncertainty metadata, portability and support for cross-media annotation of the media.
