Deliverable D 2 . 2 : Semantics

for dissemination) This deliverable presents the state-of-the-art on “Semantics Extraction from visual content”. We first give an overview of OCR methodologies dealing with visual content, namely image and video, that provide textual information. Although, this kind of analysis does not provide directly any semantics, it is a critical step involving visual content, which feeds BOEMIE’s module dedicated to semantics extraction from text. In the sequel, the document is dedicated to the semantics extraction from images and videos, for which an exhaustive survey is presented for different type of knowledge as well as different content representation. Related R&D projects that put as one of their main objectives the semantics extraction from visual content, existing systems that consist of dedicated modules to semantics extraction as well as evaluation efforts to test the performance in semantics extraction are presented.
