Abstract: The objective of the presented paper is to give a short overview about watermarking approaches for audio visual objects (AV-objects). Since the market of handling digital media within digital TV stations is strong developing in this paper aspects of innovation-related activities of watermarking applications as well as current research and investigation streams are pointed out. Furthermore an approach for watermarking of AV-objects considering DCT, Wavelet and PLT transforms is discussed.

Abstract: The paper objective is to describe an approach for a software framework consisting of an application oriented tool set for enhanced search, retrieval and processing of audio-visual (AV) content objects. Using semantic web service technologies and watermarking techniques the framework is designed to cover several aspects of object and workflow handling. It allows optimized system integration to support workflow environments realized as P2P as well as open network and mobile service approaches.

Abstract: The scope of this paper is to describe the integrated system approach for advanced processing of AV-Objects. This system approach is oriented on the design of a software framework consisting of several modules and services, whereas the service designing and composing process is oriented on the WSMO specification. The proposed integrated system approach consists mainly of a threefold approach: meta-search, recognition and classification of objects, application of watermarking methods and the integration of interoperability features of semantic web services. The integrated modules concerning the retrieval, the watermarking, the semantic annotation and the workflow aspects are overviewed.

Abstract: The paper introduces a system framework, which enables software and Service providers to generate and establish open and extensible development platforms for Web Service enabled applications. Within the system design several non-functional aspects are addressed and covered by applying a set of powerful (AI-) methodologies: interoperability and adaptability are achieved by exchanging semantically enriched Services among platform partners within P2P environments. The machine processability of ontology based structures in conjunction with "closed loop" approaches in the Service operation, maintenance and feedback cycle (QoS, full life cycle) ensures implicitly a high degree of stable adaptability and scalability, as well as the establishment of extensible platform structures (self-organizing structures). Service composability is guaranteed by applying open standards. To achieve a customizable modular development environment “experience” feedback patterns in distributed rule and case bases (CBR) are archived, evaluated and utilized within distributed decision making processes.

Abstract: In this paper the conceptualization and design of an ICT framework is proposed and discussed - an intelligent framework for supporting organizational networking and the effective sharing of resources. The challenges for this are to:
(i) provide a comfortable and "easy to use" but effective knowledge brokering environment,
(ii) used within a decision supported flexible and highly dynamic collaboration platform, and
(iii) supplemented with add-ons to fulfil security and privacy requirements.
These objectives are achieved by developing software components consisting of:
(i) ontology based and decision supported knowledge management structures applicable to different entities, and
(ii) an interoperability environment realized as a dynamic and reconfigurable platform using semantic web services and multi agent systems,
(iii) supplemented with semantic web service and agent related privacy and security modules.
The framework mirrors the modern and future oriented way of ubiquitous computing, where computers will be relegated to the background of our lives and everybody may be at the same time client, broker and, provider of services.

"New Approach for Online Case-Based Reasoning WEB-Services in Knowledge Management Applications"

H. Joachim Nern, Pautzke F., Atanasova T.
Euromedia 2003 , Plymouth, United Kingdom, April 14-16, 2003

Abstract: Due to the fact that nowadays new knowledge creation and generation is rapidly accelerating, the development of efficient tools and systems for knowledge management and reasoning is essential. A main application field in the wide area of knowledge management is designated to decision support systems - systems which provide comprehensive support in gathering, organisation, refinement and distribution of knowledge.

The initial point for presenting this paper are the results of an European project the authors have been involved in [1]. Consequently and on the basis of this former RTD actions [2, 3, 4] the authors present in this paper an enhancement of a specific type of decision support methodology - a new approach in Case Based Reasoning (CBR) for the general application in WEB-Services. The main realisation trait of this new system is the use of a closed loop approach considering and taking into account statistically evaluated user and experience feedback information implicitly. This closed loop structure assures a stable dynamically growing of the internal case bases and optimal adaptation to the user resp. systems needs.

"Multi-Agent Approach for Task Related Decision Supported Information Retrieval"

H. Joachim Nern, Atanasova T, Pautzke, F.
Euromedia 2002 April 2002, Modena, Italy

Abstract: This paper presents an approach for building research models accessing distributed and heterogene-ous knowledge pools using multi-agent information retrieval. Accordingly task-oriented scenarios for intelli-gent information retrieval are discussed. Searching and browsing activities range from a well-defined search for a specific document to a non-specific task to estimate which kind of information is available. An algorithm for information retrieval is proposed that provides decision support to optimise the search results. The system uses metadata information schemes to provide services in refining user queries to focus a search, in automatically routing queries to relevant servers and in clustering related items.

Key-Words: multi-agent system, decision support, knowledge network, metadata description schemes, information retrieval, distributed and heterogeneous knowledge pools

"Realisation of a Task Oriented Recommender System applied to XPS-Bases Research Networking"

Abstract:The realisation of a task oriented Decision Support System (DSS) used within an XPS-based research network is introduced in this paper. The knowledge (information) retrieval process is instantiated and supervised by a recommender system - supporting the user resp. researcher in determining and classifying his information requirements related to his research task. The retrieval procedure is undertaken stepwise in an iterative way, so that the user is conducted in optimising his task description and accordingly optimising his information retrieval.

The recommender system provides a multistage access cycle for converging the searching and retrieval process based on evaluation of feedback information. The system extracts out of the user’s (researcher’s) predefined task characteristically knowledge patterns and accordingly recommends relevant information objects. These objects are automatically rated with respect to their task related relevancy.
