Audiovisuelle Medien stellen Archive vor zunehmende Probleme. Ein stark wachsender (Web-)TV-Markt mit Sende- oder Rohmaterial, zunehmender Einsatz von medial aufbereitetem Lehrmaterial in Schulen, Hochschulen und Firmen, die Verbreitung der Videoanalyse als Forschungs- und Lehrmethode, die Ausbreitung von Überwachungskameras sowie die immer günstigeren Produktionsbedingungen vom professionellen Produzenten bis zum Heimvideo sind nur einige Stichworte um die neuen quantitativen Dimensionen zu umreißen. Die archivarischen und dokumentarischen Werkzeuge sind heute mit dieser Situation überfordert. Der Workshop versucht hier Probleme und Lösungsmöglichkeiten zu umreißen und beschäftigt sich mit den technologischen Fragestellungen rund um die Archivierung audiovisueller Medien, seien es analoge, digitalisierte oder digitale Medien. Dabei werden zum einen die technologischen Probleme angesprochen, die zum Aufbau und Management eines Archivs bewältigt werden müssen. Zum anderen wird der praktische Einsatz von der Gestaltung der Benutzungsoberfläche bis zur Frage des Umgangs mit kritischem Material diskutiert.:Interaction MedioVis 2.0 - A novel User Interface for Seeking Audio-Visual Media Libraries Harald Reiterer, Mathias Heilig and Sebastian Rexhausen SIVA Suite – Konzeption eines Frameworks zur Erstellung von interaktiven Videos B.

Records are essential to the efficient administration of municipalities and more critical to the facilitation of good governance, transparency and accountability. Despite this, the records management processes of many municipalities in South Africa have remained ineffective and inefficient. The study investigated the extent to which records management enhances service delivery in Mogale City Local Municipality. The objective was to determine how far sound records management goes in enhancing the public services, accountability, transparency and good governance. The study sought to address the following research questions: “What contribution, if any, does records management play in enhancing service delivery?”; “Are there any suitable standards and practices for creation and maintenance of records MCLM?”; “To what extent does records management impact on transparency and accountability in Mogale City Local Municipality?” and “Identifying the benefits derived from records management in the municipality.” The study was underpinned by the record life-cycle and records continuum models. The literature reviewed was based on themes derived from the research questions, the underpinning models and broader areas of the study. The study adopted an interpretivist paradigm, which is associated with the qualitative research approach. The study adopted a single case study design and data were collected through the use of interviews and observation. The qualitative data collected were presented and analysed in narrative description. The findings of the study revealed that there is a positive correlation between records management and effective service delivery. In conclusion, it is evident that the future well-being and quality of basic service delivery depend on the ability of the MCLM to utilise records management strategic planning processes. Records contain information that will assist the municipality in determining the required resources, and moreover, in setting or improving service standards. The records management policy in the municipality must be adhered to and practiced consistently to ensure compliance and sound records management. This affirms the need for reformed records management strategies to enable administration efficiency and improved service delivery in the municipality. / Rekords is noodsaaklik vir die doeltreffende administrasie van munisipaliteite en meer krities vir die fasilitering van goeie bestuur, deursigtigheid en verantwoordbaarheid. Ten spyte hiervan het die rekordbestuursprosesse van talle munisipaliteite in Suid-Afrika ondoeltreffend en ondoeltreffend gebly. Die studie het die mate waarin rekordbestuur die dienslewering in Mogale City Plaaslike Munisipaliteit verbeter, ondersoek. Die doel was om te bepaal hoe ver klankrekordbestuur gaan om die openbare dienste, verantwoordbaarheid, deursigtigheid en goeie bestuur te verbeter. Die studie het probeer om die volgende navorsingsvrae aan te spreek: "watter bydrae, indien enige, doen rekordbestuursspel in die verbetering van dienslewering?"; "Is daar enige geskikte standaarde en praktyke vir die skepping en instandhouding van rekords MCLM?"; "Tot watter mate het rekordbestuursimpak oor deursigtigheid en verantwoordbaarheid in Mogale City Plaaslike Munisipaliteit?" en "die identifisering van die voordele wat uit rekordbestuur in die Munisipaliteit afkomstig is." Die studie is gerugsteun deur die rekord lewe-siklus en rekords kontinuum modelle. Die literatuur is gebaseer op temas wat afgelei is van die navorsingsvrae, die onderliggende modelle en breër areas van die studie. Die studie het 'n interpretivist paradigma aangeneem, wat geassosieer word met die kwalitatiewe navorsingsbenadering. Die studie het 'n enkele gevallestudie aangeneem en data is ingesamel deur die gebruik van onderhoude en observasie. Die kwalitatiewe data wat ingesamel is, is aangebied en ontleed in narratiewe Beskrywing. Die bevindinge van die studie het getoon dat daar 'n positiewe korrelasie tussen rekordbestuur en effektiewe dienslewering is. Ten slotte is dit duidelik dat die toekomstige welstand en gehalte van basiese dienslewering afhang van die vermoë van die MCLM om rekordbestuur-strategiese beplanningsprosesse te benut. Rekords bevat inligting wat die Munisipaliteit sal help om die vereiste hulpbronne te bepaal, en verder in die opstel of verbetering van diensstandaarde. Die rekordbestuurbeleid in die munisipaliteit moet nagekom en konsekwent beoefen word om nakoming van voldoening en goeie rekordbestuur te verseker. Dit bevestig die behoefte aan Reformatoriese rekordbestuurstrategieë om administraseringdoeltreffendheid en verbeterde dienslewering in die Munisipaliteit moontlik te maak. / Information Science / M.A. (Information Science)

Background: In the life sciences, the amount of literature and experimental data grows at a tremendous rate. In order to effectively access and integrate these data, biomedical ontologies – controlled, hierarchical vocabularies – are being developed. Creating and maintaining such ontologies is a difficult, labour-intensive, manual process. Many computational methods which can support ontology construction have been proposed in the past. However, good, validated systems are largely missing. Motivation: The biocuration community plays a central role in the development of ontologies. Any method that can support their efforts has the potential to have a huge impact in the life sciences. Recently, a number of semantic search engines were created that make use of biomedical ontologies for document retrieval. To transfer the technology to other knowledge domains, suitable ontologies need to be created. One area where ontologies may prove particularly useful is the search for alternative methods to animal testing, an area where comprehensive search is of special interest to determine the availability or unavailability of alternative methods. Results: The Dresden Ontology Generator for Directed Acyclic Graphs (DOG4DAG) developed in this thesis is a system which supports the creation and extension of ontologies by semi-automatically generating terms, definitions, and parent-child relations from text in PubMed, the web, and PDF repositories. The system is seamlessly integrated into OBO-Edit and Protégé, two widely used ontology editors in the life sciences. DOG4DAG generates terms by identifying statistically significant noun-phrases in text. For definitions and parent-child relations it employs pattern-based web searches. Each generation step has been systematically evaluated using manually validated benchmarks. The term generation leads to high quality terms also found in manually created ontologies. Definitions can be retrieved for up to 78% of terms, child ancestor relations for up to 54%. No other validated system exists that achieves comparable results. To improve the search for information on alternative methods to animal testing an ontology has been developed that contains 17,151 terms of which 10% were newly created and 90% were re-used from existing resources. This ontology is the core of Go3R, the first semantic search engine in this field. When a user performs a search query with Go3R, the search engine expands this request using the structure and terminology of the ontology. The machine classification employed in Go3R is capable of distinguishing documents related to alternative methods from those which are not with an F-measure of 90% on a manual benchmark. Approximately 200,000 of the 19 million documents listed in PubMed were identified as relevant, either because a specific term was contained or due to the automatic classification. The Go3R search engine is available on-line under www.Go3R.org.
