- Abstract
- Im Jänner 2014 startete das dreijährige, vom Bundesministerium für Wissenschaft, Forschung und Wirtschaft geförderte Hochschulraumstrukturmittelprojekt e-Infrastructures Austria, das den koordinierten Ausbau und die Weiterentwicklung von Repositorieninfrastrukturen, ein strategisches Konzept für zukünftiges Forschungsdatenmanagement in Österreich sowie den Aufbau eines Wissensnetzwerks für die sichere Archivierung und Verbreitung von elektronischen Publikationen, Multimedia-Objekten und anderen digitalen Daten aus Forschung und Lehre verfolgt. Dabei geht es sowohl um die Errichtung von technischen Infrastrukturen als auch um die Schaffung einer Wissensbasis für zukünftige Serviceangebote in diesem Bereich. Grundlage für die erfolgreiche Abwicklung des Projekts war der rasche Aufbau eines österreichweiten Netzwerks von 25 Institutionen, davon 20 Universitäten. Die Zusammenarbeit erfolgt über Instrumente, die bei Bedarf erweiterbar sind: fünf Gremien und eine Governance, die Rollen und Verantwortlichkeiten regelt. Die identifizierten Themenbereiche werden in interdisziplinären und auf Zeit eingesetzten "Work-Package-Clustern" behandelt. Das Projekt bietet eine Plattform für zahlreiche Vernetzungsforen, Sitzungen und Weiterbildungseinheiten, in denen alle Bundesländer einbezogen sind, und zu denen nicht nur Bibliothekarinnen und Bibliothekare, sondern auch weitere relevante Stakeholder, wie etwa Vertreterinnen und Vertreter aus den lokalen IT-Einrichtungen, Forschungsservices und juristischen Abteilungen sowie Wissenschaftlerinnen und Wissenschaftler, eingeladen sind. Somit greift das Projekt nicht nur thematisch, sondern auch organisatorisch weit über die konkrete Bibliotheksperspektive hinaus. Der Bericht informiert über die Projektziele von e-Infrastructures Austria, über die 2014 erfolgte Etablierung des Netzwerks und der Gremien sowie über die im ersten Jahr des Projekts in den Clustern erreichten Ergebnisse und die 2015 zu leistenden Aufgaben.

- Abstract
- The explosive growth of literature and data in the life sciences challenges researchers to keep track of current advancements in their disciplines. Novel approaches in the life science like the One Health paradigm require integrated methodologies in order to link and connect heterogeneous information from databases and literature resources. Current publications in the life sciences are increasingly characterized by the employment of trans-disciplinary methodologies comprising molecular and cell biology, genetics, genomic, epigenomic, transcriptional and proteomic high throughput technologies with data from humans, plants, and animals. The literature search engine LIVIVO empowers retrieval functionality by incorporating various literature resources from medicine, health, environment, agriculture and nutrition. LIVIVO is developed in-house by ZB MED - Information Centre for Life Sciences. It provides a user-friendly and usability-tested search interface with a corpus of 55 Million citations derived from 50 databases. Standardized application programming interfaces are available for data export and high throughput retrieval. The search functions allow for semantic retrieval with filtering options based on life science entities. The service oriented architecture of LIVIVO uses four different implementation layers to deliver search services. A Knowledge Environment is developed by ZB MED to deal with the heterogeneity of data as an integrative approach to model, store, and link semantic concepts within literature resources and databases. Future work will focus on the exploitation of life science ontologies and on the employment of NLP technologies in order to improve query expansion, filters in faceted search, and concept based relevancy rankings in LIVIVO.

- Abstract
- There are many advantages for Digital Libraries in indexing with classifications or thesauri, but some current disincentive in the lack of flexible retrieval tools that deal with compound descriptors. This demonstration of a research prototype illustrates a matching function for compound descriptors, or multi-concept subject headings, that does not rely on exact matching but incorporates term expansion via thesaurus semantic relationships to produce ranked results that take account of missing and partially matching terms. The matching function is based on a measure of semantic closeness between terms.The work is part of the EPSRC funded FACET project in collaboration with the UK National Museum of Science and Industry (NMSI) which includes the National Railway Museum. An export of NMSI's Collections Database is used as the dataset for the research. The J. Paul Getty Trust's Art and Architecture Thesaurus (AAT) is the main thesaurus in the project. The AAT is a widely used thesaurus (over 120,000 terms). Descriptors are organised in 7 facets representing separate conceptual classes of terms.The FACET application is a multi tiered architecture accessing a SQL Server database, with an OLE DB connection. The thesauri are stored as relational tables in the Server's database. However, a key component of the system is a parallel representation of the underlying semantic network as an in-memory structure of thesaurus concepts (corresponding to preferred terms). The structure models the hierarchical and associative interrelationships of thesaurus concepts via weighted poly-hierarchical links. Its primary purpose is real-time semantic expansion of query terms, achieved by a spreading activation semantic closeness algorithm. Queries with associated results are stored persistently using XML format data. A Visual Basic interface combines a thesaurus browser and an initial term search facility that takes into account equivalence relationships. Terms are dragged to a direct manipulation Query Builder which maintains the facet structure.

- Abstract
- Music websites are ubiquitous, and music downloads, such as MP3, are a major source of Web traffic. As the amount of musical content increases and the Web becomes an important mechanism for distributing music, we expect to see a rising demand for music search services. Many currently available music search engines rely on file names, song title, composer or performer as the indexing and retrieval mechanism. These systems do not make use of the musical content. We believe that a more natural, effective, and usable music-information retrieval (MIR) system should have audio input, where the user can query with musical content. We are developing a system called MusArt for audio-input MIR. With MusArt, as with other audio-input MIR systems, a user sings or plays a theme, hook, or riff from the desired piece of music. The system transcribes the query and searches for related themes in a database, returning the most similar themes, given some measure of similarity. We call this "retrieval by query." In this paper, we describe the architecture of MusArt. An important element of MusArt is metadata creation: we believe that it is essential to automatically abstract important musical elements, particularly themes. Theme extraction is performed by a subsystem called MME, which we describe later in this paper. Another important element of MusArt is its support for a variety of search engines, as we believe that MIR is too complex for a single approach to work for all queries. Currently, MusArt supports a dynamic time-warping search engine that has high recall, and a complementary stochastic search engine that searches over themes, emphasizing speed and relevancy. The stochastic search engine is discussed in this paper.

- Abstract
- From a quantitative and qualitative point of view the ETH Library is offering its users an extensive choice of information services. In this respect all researchers, all scientists and also all students have access to nearly all relevant information. This is one side of the coin. On the other hand, this broad, but also heterogeneous bundle of information sources has disadvantages, which should not be underestimated: The more information services and information channels you have, the more complex is it to find what you want to get for your scientific work. A portal-like integration of all the different information resources is still missing. The vision, the main goal of the project "Knowledge Portal" is, to develop a central access system in terms of a "single-point-of-access" for all electronic information services. This means, that all these sources - from the library's catalogue and the fulltext inhouse applications to external, licensed sources - should be accessible via one central Web service. Although the primary target group for this vision is the science community of the ETH Zurich, the interested public should also be taken into account, for the library has also a nation-wide responsibility.The general idea to launch a complex project like that comes from a survey the library did one and a half years ago. We asked a defined sample of scientists what they expected to get from their library and one constant answer was, that they wanted to have one point of access to all the electronic library services and besides this, the search processes should be as simple as possible. We accepted this demand as an order to develop a "single-point-of-access" to all electronic services the library provides. The presentation gives an overview about the general idea of the project and describes the current status.

- Abstract
- The European Commission's goal for Europeana is to make European information resources easier to use in an online environment. It will build on Europe's rich heritage, combining multicultural and multilingual environments with technological advances and new business models. The Europeana prototype is the result of a 2-year project that began in July 2007. Europeana.eu went live on 20 November 2008, launched by Viviane Reding, European Commissioner for Information Society and Media. Europeana.eu is about ideas and inspiration. It links the user to 2 million digital items: images, text, sounds and videos. Europeana is a Thematic Network funded by the European Commission under the eContentplus programme, as part of the i2010 policy. Originally known as the European digital library network - EDLnet - it is a partnership of 100 representatives of heritage and knowledge organisations and IT experts from throughout Europe. They contribute to the work packages that are solving the technical and usability issues. The project is run by a core team based in the national library of the Netherlands, the Koninklijke Bibliotheek. It builds on the project management and technical expertise developed by The European Library, which is a service of the Conference of European National Librarians. Content is added via so called aggregators, national or domain specific portals aggegrating digital content and channelling it to Europeana. Most of these portals are being developed in the framework of EU funded projects, e.g. European Film Gateway, Athena and EuropeanaLocal. Overseeing the project is the EDL Foundation, which includes key European cultural heritage associations from the four domains. The Foundation's statutes commit members to: * providing access to Europe's cultural and scientific heritage through a cross-domain portal; * co-operating in the delivery and sustainability of the joint portal; * stimulating initiatives to bring together existing digital content; * supporting digitisation of Europe's cultural and scientific heritage. Europeana.eu is a prototype. Europeana Version 1.0 is being developed and will be launched in 2010 with links to over 6 million digital objects.

- Abstract
- This paper presents the approach and first results of the classification mapping process in the EU project Renardus. The outcome in Renardus is a cross-browsing feature based an the Dewey Decimal Classification (DDC) and improved subject searching across distributed and heterogeneous European subject gateways. The paper presents the project's initial experiences and decisions, e.g. an investigation of the use of classification systems by Renardus partners' gateways, general mapping approaches and issues, the definition of mapping relationships and some information an technical solutions and the mapping tool. There is also a demonstration of the use of the mapping information in Renardus and the presentation of several features that have been implemented to aid end-user navigation in a large and deep browsing structure like the DDC. Classification mapping for crossbrowsing is a labour intensive and complex effort which at the moment raises many open questions and leaves many more future potential work tasks than completed useful solutions.
