The Content-based Image Retrieval (CBIR) methods have been applied to medical field to aid diagnosis and other medical processes for a relatively long time. This type of systems, with the growth of digital medical image databases, sometimes does not provide information tailored to the end user requirements. Typically there is a semantic gap between the low-level features extracted form the images and high-level concepts required by the user. This paper proposes an ontology-based search and retrieval as a supplementary method to associate high-level concepts and semantics to medical image data and exploit these semantic media for information search and retrieval. The main goal is to perform a search on a medical image repository and to retrieve relevant medical images and information to a particular case in order to assist diagnosis process. We demonstrate the functionality of the system in case of a mammography imaging database. The system uses an ontology-based search and retrieval for the medical data as a complementary solution to provide more efficient and insight access to the stored data. © 2007 IEEE.

Information collection, selection, structuring, and presentation design are the core considerations for general hypermedia presentation generation systems. The content collection process can be enhanced by retrieving semantically related information objects, relevant to the topic selected by an author. Once relevant information objects are available, the content selection process suggests semantically related resources for the author's selection based on data usage history. The information objects are represented by media assets and descriptive documents. The semantic web technology that allows resource interoperability can be used for content description and interpretation of these information objects. By utilizing a semiautomatic approach, authors can be assisted at different stages of the presentation generation process. In this research, adaptation constraints are established independent of the author's proficiency (i.e. novice, intermediate or expert) by applying the Hidden Markov Model methodology. Semantically related media objects are suggested to authors for selection based on their interactive behaviour and the strength of semantic relations. The paper describes an application of the Hidden Markov Model in the initial authoring phases of semiautomatic hypermedia presentation systems.

Multimedia information system design has been recently influenced by state-of-the-art technologies such as those provided by semantic web. This paper introduces an information search and retrieval methodology that employs semantic web technologies for its data representation and reasoning tasks. Creating a meaningful multimedia presentation is an attempt to answer a user's query using a knowledge representation structure. In this case, the system instead of providing a list of results, as happens in many typical information search and retrieval systems, collects a list of selected items based on the relevancy to the queried topic and also meaningful relationships between data objects. The collected information is used for the construction of an automated presentation to demonstrate the results to the user. The paper concentrates in particular on the content selection, narration structuring, and presentation design and generation processes. The implementation of an automatic presentation generation facility in an integrated system, called MANA, is described through the paper. MANA is designed to generate adaptive and automatic presentations based on users' perspectives and preferences on the queried topic.

Abstract - Multimedia documents are encompassed with rich expressive capabilities due to integration of different forms of continuous and non-continuous media objects. These media assets can easily win author's attention in a multimedia presentation. Multimedia authoring involves collecting relevant multimedia objects, structuring retrieved objects, and presenting information objects in a coherent way that would be meaningful to the author. The semantic web technology offers a promising approach for modeling knowledge associated with information objects, available as media assets and descriptive documents. The semi-automatic approach facilitates the author to browse, select, and arrange semantically relevant content appropriate for her/his presentation in the semantic web framework. A discourse model assists the presentation generation process by narratively structuring presentation contents that involves discussion of a subject with a theme. The paper describes an application of Agglomerative clustering that provides structures for simple interactive selection and rapid non-linear expansion of the author preferred subject in the context of hypermedia presentation regeneration.
