  • Keynote Daniel Keim: Solving Problems with Visual Analytics: Challenges and Applications

    by Daniel Keim

    Never before in history data is generated and collected at such high volumes as it is today. As the volumes of data available to business people, scientists, and the public increase, their effective use becomes more challenging. Keeping up to date with the flood of data, using standard tools for data analysis and exploration, is fraught with difficulty. The field of visual analytics seeks to provide people with better and more effective ways to understand and analyze large datasets, while also enabling them to act upon their findings immediately. Visual analytics integrates the analytic capabilities of the computer and the abilities of the human analyst, allowing novel discoveries and empowering individuals to take control of the analytical process. Visual analytics enables unexpected and hidden insights, which may lead to beneficial and profitable innovation. The talk presents the challenges of visual analytics and exemplifies them with several application examples, which illustrate the exiting potential of current visual analysis techniques but also their limitations.

  • Awareness Support in Scientific Event Management with ginkgo

    The management of scientic events is a prestigious job that goes together with many tasks that have to be carried out in a timely and highly parallel fashion. Conference management systems (CMSs) have simplied the process and have given decision-support features to the organizers but still there is room for improvements. With the social media movement of the last decade, computer-mediated social interactions and professional networking have also gained importance for scholars. Those interactions take place outside of CMSs. Thus, a rich source of information is ceded to social networking services that could be used for a better quality of service and more awareness support for all stakeholders in CMSs. In this paper we introduce ginkgo as a novel approach to scientic event management that brings together well-known features of classic CMSs with those of common features of social networking sites to make scientic event management more social and awareness supporting.

  • Integrating Interactive Visualization With Automated Planning for Cooperative Resource Scheduling

    Assignment of sta to work tasks is a complex problem that involves a large number of factors and requires a lot of expertise. Long term as well as short term requirements need to be met which demands exible solutions. Software tools can aid planners in reaching optimal dispatching plans but currently available solutions provide only incomplete support. This paper describes the design, development, and evaluation of a prototype for semi-automated assignment planning called
    A-Plan. We have carried out this work in the context of a gas device maintenance provider. In A-Plan, assignments of service technicians to customers are displayed visually and can be modied by direct manipulation. Smooth cooperative work is possible and an optimization algorithm has been integrated that facilitates semi-automatic planning. A qualitative evaluation with potential users and IT professionals provided encouraging feedback on the proposed integration of automated methods and interactive visual interfaces.

  • Beyond Collaborative Filtering: Generating Local Top-N Recommendations for Personal Learning Environments

    In the field of personal learning environment (PLE) research is focusing on the generation and provision of recommendations. Amongst others, approaches reach from decision making tools based on psycho-pedagogical principles over specialized social recommender functionality up to general community or context-aware recommendations. The variety of the solutions results from the fact that pure collaborative filtering (CF) techniques are not sufficient for PLE-based scenarios. In this paper we propose utilizing learner interaction recordings for generating PLE recommendations fitting the educational and social context of a learner. Besides pointing out how we have realized this approach as part of a research prototype, we evaluate and discuss such recommendations generated from data captured in former studies.

  • Visualizing Alternative Scenarios of Evolution in Heritage Architecture

    Our objective is to support reasoning tasks in heritage architecture with graphics enabling analysts to visualise and share their understanding of how, from a given set of information, alternative scenarios or evolution can be inferred. The paper comments on the nature of the cognitive processes in historical sciences, and on factors that need to be weighed when interpreting sets of information. Visual solutions are proposed, and illustrated on real cases in Kraków Poland. They help spotting where alternative explanations should be considered in order to avoid unjustified assumptions and certitudes on the evolution of artefacts. The contribution expects to demonstrate that reasoning on uncertainties in historical sciences can be fruitfully backed up by concepts and practices from the infovis community.

  • Inverse Queries: How to Get This Answer?

    Although inverse problems are well studied in engineering, physics and computer graphics this uncommon perspective has been less investigated in many other contexts where it also offers
    some potential interest. Basically an inverse problem (or inverse modeling) aims to find the parameter values of a model that can have produced a given result. This paper adopts this point of view in order to invert queries. Therefore the main objective becomes to find the query criteria that might have produced a known result set. In order to structure the field of investigation, a list of various inverse queries is proposed. Out of the five identified categories, the paper focuses on the simplest one: the inverse Boolean conjunctive queries composed of n criteria each involving one attribute taking orderable values. Some theoretical issues raised by this type of inverse query are discussed in detail. Next, the paper describes a solution to integrate such inverse queries in user interfaces. Finally a prototype implementing one of the possible solutions to materialize inverse queries is presented.

  • A Visual Analytics Approach to Dynamic Social Networks

    The visualization and analysis of dynamic networks have become increasingly important in several fields, for instance sociology or economics. The dynamic and multi-relational nature of this data
    poses the challenge of understanding both its topological structure and how it changes over time. In this paper we propose a visual analytics approach for analyzing dynamic networks that integrates: a dynamic layout with user-controlled trade-off between stability and consistency; three temporal views based on different combinations of node-link diagrams (layer superimposition, layer juxtaposition, and two-and-a-halfdimensional view); the visualization of social network analysis metrics; and specific interaction techniques for tracking node trajectories and node connectivity over time. This integration of visual, interactive, and automatic methods supports the multifaceted
    analysis of dynamically changing networks.

  • Towards a Comprehensive Call Ontology for Research 2.0

    A Call for Papers (CfP) is a small, but well-structured and information-rich message with a relatively short lifespan. CfP plays an important role in academic life, not just as an advertisement format, but also as a trigger of and advance organiser for collaborative academic writing. This paper explores
    the possibilities to create a comprehensive ontology for CfP so that is would be relevant and useful in Research 2.0 context for two main target groups: authors involved in collaborative writing of academic papers, and conference organisers or journal editors. Our study is conducted in three phases. First, we identify existing ontologies and other representation frameworks, which could
    provide concepts relevant for CfP. Next, a sample of conference CfPs is analysed and compared, to find out the common structures and peculiarities, which could be used for extending the existing
    ontologies. Finally, we propose Call ontology together with two usage scenarios.

  • Semantically Driven Social Data Aggregation Interfaces for Research 2.0

    We propose a framework to address an important issue in the context of the ongoing adoption of the “Web 2.0” in science and research, often referred to as “Science 2.0” or “Research 2.0”. A growing number of people are linked via acquaintances and online social networks such as Twitter allows indirect access to a huge amount of ideas. These ideas are contained in a massive human information flow [35]. That users of these networks produce relevant data is being shown in many studies [1][2][28][36]. The problem however lies in discovering and verifying such a stream of unstructured data items. Another related problem is locating an expert that could provide an answer to a very specific research question. We are using semantic technologies (RDF2,SPARQL3), common vocabularies(SIOC4, FOAF5,SWRC6) and Linked Data (DBpedia7, GeoNames8, CoLinDa9) [3][4][5] to extract and mine the data about scientific events out of context of microblogs.
    Hereby we are identifying persons and organization related to them based on entities of time, place and topic. The framework provides an API that allows quick access to the information that is analyzed by our system. As a proof-of-concept we explain, implement and evaluate such a researcher profiling use case. It involves the development of a framework that focuses on the proposition of researches based on topics and conferences they have in common. This framework provides an API that allows quick access to the analyzed information. A demonstration application: “Researcher Affinity Browser” shows how the API supports developers to build rich internet applications for Research 2.0. This application also introduces the concept “affinity” that exposes the implicit proximity between entities and users based on the content users produced. The usability of a demonstration application and the usefulness of the framework itself are investigated with an explicit evaluation questionnaire. This user feedback led to important conclusions about successful achievements and opportunities to further improve this effort.

  • Visual Analytics for Stochastic Simulation in Cell Biology

    Visual Analytics is successfully employed for an integrated data analysis by means of combining visual and analytical methods. The starting point for current Visual Analytics tools and work
    ows is usually the readily available data set. Rarely though, Visual Analytics goes beyond the data
    set and also incorporates the data generating processes that have led to the data in the rst place into the analysis. And indeed, in many use case scenarios, this is hardly possible, as these processes cannot be captured as data to be analyzed themselves. Yet for the applications, in which this is
    feasible, new opportunities and challenges open up. In this paper, we illustrate these opportunities and challenges by our eorts to bring together Visual Analytics and stochastic simulation for cell biological applications. The integration of both is possible, as the data generating process runs in silico and can thus be captured and analyzed alongside the mere simulation result. For this, we present solutions and tools, which permit Visual Analytics on all stages of this particular data generating process on the stages of the model, the experiment, the simulation runs, and a combination of all three.
