Abstract: Ausgewählte Visualisierungsanwendungen der jüngeren Vergangenheit, die den Retrievalprozess betreffen, werden vorgestellt. Die Einsatzszenarien reichen von mobilen kleinformatigen Anwendungen bis zu großformatigen Darstellungen auf hochauflösenden Bildschirmen, von integrativen Arbeitsplätzen für den einzelnen Nutzer bis zur Nutzung interaktiver Oberflächen für das kollaborative Retrieval. Das Konzept der Blended Library wird erläutert. Perspektivische Überlegungen zu zukünftigen Entwicklungsschritten von Bibliothekskatalogen sowie zum Einfluss von Visualisierungsanwendungen auf die Informationspraxis werden angestellt. (DIPF/Orig.)
Abstract (english): An overview of recent visual applications in the field of information searching is given. Application settings for information visualization span from small-sized mobile devices to wall-sized high resolution displays, from integrative workplaces for individual use to interactive surfaces for collaborative information seeking activities. The idea of the Blended Library is presented. Possible next stages of library catalogue development are discussed. Finally, some observations regarding the influence of visualization applications on information practice are mentioned. (DIPF/Orig.)

Abstract: Neural networks have recently been proposed for multi-label classification because they are able to capture and model label dependencies in the output layer. In this work, we investigate limitations of BP-MLL, a neural network (NN) architecture that aims at minimizing pairwise ranking error. Instead, we propose to use a comparably simple NN approach with recently proposed learning techniques for large-scale multi-label text classification tasks. In particular, we show that BP-MLL's ranking loss minimization can be efficiently and effectively replaced with the commonly used cross entropy error function, and demonstrate that several advances in neural network training that have been developed in the realm of deep learning can be effectively employed in this setting. Our experimental results show that simple NN models equipped with advanced techniques such as rectified linear units, dropout, and AdaGrad perform as well as or even outperform state-of-the-art approaches on six large-scale textual datasets with diverse characteristics.

Abstract: Digital libraries allow us to organize a vast amount of publications in a structured way and to extract information of user's interest. In order to support customized use of digital libraries, we develop novel methods and techniques in the Knowledge Discovery in Scientific Literature (KDSL) research program of our graduate school. It comprises several sub-projects to handle specific problems in their own fields. The sub-projects are tightly connected by sharing expertise to arrive at an integrated system. To make consistent progress towards enriching digital libraries to aid users by automatic search and analysis engines, all methods developed in the program are applied to the same set of freely available scientific articles.

Abstract: Collections of topically related documents held by digital libraries are valuable resources for users; however, as collections grow, it becomes more difficult to search them for specific information. Structure needs to be introduced to facilitate searching. Assigning index terms is helpful, but it is a tedious task even for professional indexers, requiring knowledge about the collection in general, and the document in particular. Automatic index term assignment (ITA) is considered to be a great improvement. In this paper we present a hybrid approach to index term assignment, using a combination of keyphrase extraction and multi-label classification. Keyphrase extraction efficiently assigns infrequently used index terms, while multi-label classification assigns frequently used index terms. We compare results to other state-of-the-art approaches for related tasks. The assigned index terms allow for a clustering of the document collection. Using hybrid and individual approaches, we evaluate a dataset consisting of German educational documents that was created by professional indexers, and is the first one with German data that allows estimating performance of ITA on languages other than English.

Abstract: This paper highlights how Semantic Web technologies facilitate new socio-technical interactions between researchers and libraries focussing research data in a Virtual Research Environment. Concerning data practices in the fields of social sciences and humanities, the worlds of researchers and librarians have so far been separate. The increased digitization of research data and the ubiquitous use of Web technologies change this situation and offer new capacities for interaction. This is realized as a semantically enhanced Virtual Research Environment, which offers the possibility to align the previously disparate data life-cycles in research and in libraries covering a variety of inter-activities from importing research data via enriching research data and cleansing to exporting and sharing to allow for reuse. Currently, collaborative qualitative and quantitative analyses of a large digital corpus of educational lexica are carried out using this semantic and wiki-based research environment.

Abstract (english): This paper presents results from the analysis of user interactions in the GEI (German Education Index) specialised search engine. The main interest of this study is getting insights into the GEI users typical search behaviour to identify optimisation potential for the further development of the GEI search engine. Based on a sample of query logfiles, the study has revealed that the users apply advanced search functionalities and query reformulation tactics adequately, though not frequently, and that more support in their application could possibly increase the effectiveness of the searches in the GEI.

Abstract (english): Virtual research environments (VREs) aim to enhance research practice and have been identified as drivers for changes in libraries. This paper argues that VREs in combination with Semantic Web technologies offer a range of possibilities to align research with library practices. This main claim of the article is exemplified by a metadata integration process of bibliographic data from libraries to a VRE which is based on Semantic MediaWiki. The integration process rests on three pillars: MediaWiki as a web-based repository, Semantic MediaWiki annotation mechanisms, and semi-automatic workflow management for the integration of digital resources. Thereby, needs of scholarly research practices and capacities for interactions are taken into account. The integration process is part of the design of Semantic MediaWiki for Collaborative Corpora Analysis (SMW-CorA) which uses a concrete research project in the history of education as a reference point for an infrastructural distribution. Semantic MediaWiki thus provides a light-weight environment offering a framework for re-using heterogeneous resources and a flexible collaborative way of conducting research.
