Ontology-based Photo Annotation Our Approach Developing Ontologies
an image are limited. Typically, the databases have a semistructured indexing scheme that allows a keyword search but not much more to help the user find the desired photograph. Currently, researchers promote the use of explicit background knowledge as a way out of the search problems encountered on the Internet and in multimedia databases. The semantic Web1 and emerging standards (such as the ...
متن کاملOntology-Based Linguistic Annotation
We propose an ontology-based framework for linguistic annotation of written texts. We argue that linguistic annotation can be actually considered a special case of semantic annotation with regard to an ontology such as pursued within the context of the Semantic Web. Furthermore, we present CREAM, a semantic annotation framework, as well as its concrete implementation OntoMat and show how they c...
متن کاملOntology-based Technical Text Annotation
Powerful tools could help users explore and maintain domain specific documentations, provided that documents have been semantically annotated. For that, the annotations must be sufficiently specialized and rich, relying on some explicit semantic model, usually an ontology, that represents the semantics of the target domain. In this paper, we learn to annotate biomedical scientific publications ...
متن کاملInterest Point and Segmentation-Based Photo Annotation
Our approach to the ImageCLEF 2009 tasks is based on image segmentation, SIFT keypoints and Okapi BM25-based text retrieval. We use feature vectors to describe the visual content of an image segment, a keypoint or the entire image. The features include color histograms, a shape descriptor as well as a 2D Fourier transform of a segment and an orientation histogram of detected keypoints. We train...
متن کاملOntology based Text Annotation - OnTeA
In this paper we describe a solution for the semi-automatic ontology based text annotation (OnTeA) tool. The tool analyzes a document or text using regular expression patterns and detects equivalent semantics elements according to the defined domain ontology.
