Skalierbare Umgebungen für digitale Langzeitarchivierung

Details :


The SCAPE project will enhance the state of the art of digital preservation in three ways: by developinginfrastructure and tools for scalable preservation actions; by providing a framework for automated,quality-assured preservation workflows and by integrating these components with a policy-based preservationplanning and watch system. These concrete project results will be validated within three large-scale Testbedsfrom diverse application areas: Digital Repositories from the library community, Web Content from the webarchiving community, and Research Data Sets from the scientific community. Each Testbed has been selectedbecause it highlights unique challenges.SCAPE will develop scalable services for planning and execution of institutional preservation strategies on anopen source platform that orchestrates semi-automated workflows for large-scale, heterogeneous collections ofcomplex digital objects. These services will be able to:* Identify requirements for preserving all or parts of a repository through characterisation and trend analysis;* Define responses to those needs using formal descriptions of preservation policies and preservation plans;* Allow a high degree of automation, virtualization of tools, and scalable processing;* Monitor the quality of preservation processes.The SCAPE consortium brings together experts from memory institutions, data centres, research labs,universities, and industrial firms in order to research and develop scalable preservation systems that can bepractically deployed within the project lifetime. SCAPE is dedicated toward producing open source softwaresolutions available to the entire digital preservation community. The project results will be curated and furtherexploited by the newly founded Open Planets Foundation. Project results will also be exploited by an SMEand research institutions within the consortium catering to the preservation community and by two industrial ITpartners.

Step by Step

Details :


STEP by STEP is a bundle of measures to rehabilitate released prisoners. An important contribution is education and training to get a job. A large part of the released prisoners are practically illiterate and need education at a very low level and with use of a very simple and easy understandable language. Special e-learning software with a very restricted use of text and language is developed to support the trainings.

Support for Authoring and Transformation of Clinical Guidelines and Protocols

Details :


Clinical guidelines and protocols (CGPs) are promising means to improve the quality of health care. Supporting their application by computer systems in connection with electronic patient records increases conformance and reduces workload. To achieve this, CGPs must be translated to a computer readable form. The considerable effort to do so can be reduced by means of Information Extraction. Efficiently performing this task is still an open research frontier. At the same time, there is already valuable experience from previous efforts in the field, which is currently not taken to the field of creating CGPs in their original form (free text and diagrams, in natural language).In previous projects, we developed expertise in the fields of guideline modelling, with and without the use of Information Extraction, and in guideline validation, verification, and execution. Combining it with available open-source software, we intend to develop a comprehensive solution for authoring CGPs in formal and informal (freetext) form by a distributed team of experts with complementary expertise. To arrive at this, we will take the following actions. - Evaluation of existing partial solutions for the task of authoring highly structured, large documents in a distributed environmentby contributors with heterogeneous background. - Integration of a suitable selection of open-source solutions, complementing them with custom-made middleware where required by the particular needs of the intended field of application. - Further development of Information Extraction methods to support the transformation of CGPs to formal models. - Creation of demonstration use-cases and evaluation of the prototype with domain experts. - Creation of educational material and organisation of a workshop and individual meetings with interested experts to raise the awareness in the community for thethen available solutions. The result of this research will be models and methods that can take the state of art in the important field of authoring formal and informal CGPs a significant step towards practical application. By applying these models and methods not only the transformation into computer-interpretable guideline formats will be facilitated, but also creators of new freetext CGPs will benefit from an environment that assists collaborative aspects and distributed work.

System Wide Information Sharing

Details :


The research project SWIS (System Wide Information Sharing) aims at providing a scientifically robust and practicable method for establishing information sharing among partners, legacy systems and services via a heterogeneous infrastructure applying the aviation domain as an example. This includes:¿Development of a concise semantic to describe the source and target systems in terms of data requirements and functional ranges as well as constraints of the infrastructure.¿ Algorithms to deduce the ¿intelligent plumbing¿ from semantic descriptions. This defines an automated way to acquire the canonical data exchange model as well as the resulting data flows and interface function calls. ¿ Description of the solution architecture with all functional components. ¿Development of a prototype integration four example applications utilizing the results of the research project. The key motivation for SWIS is to elaborate fitting mechanisms based on existing EAI (Enterprise Application Integration) paradigms and know-how. In particular, SWIS will allow for implementing IT system integration in highly complex environments regardless of location and number of legacy applications involved.

Telelearning for imprisoned people

Details :


Central parts of Telfi (Tele-learning for imprisoned people) are training measures for prisoners by taking advantage of the opportunities offered by E-Learning. An advantage is the high flexibility of E-Learning. Trainees themselves largely decide on their pace. This means that E-Learning is able to interest clients who are hardly attracted by traditional teaching and learning methods.E-Learning requires appropriate equipment and technical structures. They have been installed and developed in the participating prisons by means of the Ministry of Justice and with the support of Institute of Software Technology, Vienna University of Technology. Above all a¿prison education server¿ has been installed and has been developed within the project. This server is an important step towards a wider use of e-learning in Austrian prisons and towards mainstreaming the ideas of the project. After Telfi the server should enable Austrian prisons to organize E-Learning courses by themselves by taking advantage of the server and the software stored on it.

Temporal-Consistent Stereo Matting for High-Quality Novel View Synthesis and Visual Effects

Details :


This project develops new image processing techniques for the emerging field of 3D television. Given two videos that are recorded by slightly displaced cameras, we aim to extract (1) the opacity values of individual pixels, (2) a depth reconstruction of the scene and (3) the temporal relationship between the images of a sequence. The computed information can serve as the input for an autostereoscopic display that exploits our results to provide the user with temporal-smooth depth impression. Moreover, our results offer the exciting possibility for free-viewpoint video where the user has control over a virtual camera and can select the preferred viewpoint. To suit the needs of these applications, our focus lies on generating results of high quality that outperform the current state-of-the-art. Due to addressing the image matting problem, we will also be able to handle fuzzy and hairy objects that are traditionally difficult in image processing.

The Essence of Patent Retrieval

Details :


In this project, an alternative way to capture the concept of a patent will be explored. This willinvestigate logic or semi logical features of expression in patent text. There are some grammarmodels that try to capture the semantics of a sentence i.e. leaving the surface base of a sentence,which is represented by the sentence words, and transforming sentence into a semanticrepresentation format. Examples of grammar models that with different methods transformsurface base to semantic representation are: Head-driven Phrase Structure Grammar,Construction Grammar, and Frame semantics.

The Virtual 3D Social Experience Museum

Details :


The goal of the project"The Virtual 3D Social Experience Museum"is to provide a community platform for the presentation, discussion, annotation and the experience of cultural artefacts all blended together in a multi-user virtual environment with Web 2.0 capabilities for user-generated contentThe benefit for the visitor is to explore and to annotate the wealth of cultural heritage starting from one virtual place where objects from geographically and culturally disparate real places are brought together to create a holistic experience. For the museum as content provider the benefit is an easy to follow avenue to engage the visitor in a dialogue that will lead to a deeper understanding of the visitors'needs and expectations for the real museum or heritage site. Moreover, since visitors are able to annotate and to create content, the entire set of artefacts can be semantically enriched.In cooperation with the Museum and the Library of the City of Vienna a showcase will be developed either addressing the temporary exhibition Vienna 1930 or parts of the museum's permanent collection extended with artefacts of the Library.The visitor contributions to the showcase will be analysed to provide the museum with feedback on visitor reception. In particular we will provide content analysis of textual annotations, social network analysis of contributing visitors, as well as general analysis of interaction patterns with the exhibition.

TRACK and TRADE: Creating a Data Mart for Floating Car Data

Details :


With the number of vehicles, both private and commercial, in urban areas steadily increasing, accurate traffic information becomes an increasingly important commodity A change in transport policy, e.g., increased use of public transport and efficient inter-modal transport, will only have a medium to long-term effect on improving the traffic situations in inner-city areas.To create high-quality content for traffic management applications and mobility services, reliable and inexpensive real-time traffic is essential. The TRACK&TRADE project relies on floating car data (FCD) to solve a number of well-known problems generating traffic content. While conventional traffic data collection systems have a high infrastructure maintenance and communication expense, exploits the FCD approach synergies with existing GPS-based fleet disposition systems.The scope of the project is to develop an FCD data mart that allows for the collection and integration of FCD data from as many data suppliers as possible. In turn, the data mart will supply aggregated datasets as well as valued-added services. Services include the provision of maps visually illustrating travel times and the provision of current and predicted travel times for parts of the road network. These services will be provided using XML and Web services and should simplify the creation of more complex services such routing and navigation as well as traffic forecasts.Trading FCD data and the provision of related services would serve two main purposes. (i) It creates an additional income stream for the data producers from an otherwise worthless resource and (ii) given that such data becomes generally available, it allows for the provision of improved traffic information services through a series of more or less technological means. With an increasing number of commercial vehicles (e.g., taxi fleets) being equipped with GPS, a successful business case for the FCD technology can be demonstrated.
