2nd CALL FOR PAPERS Knowledge Maps and Information Retrieval (KMIR) Workshop at Digital Libraries 2014 11th September 2014, London, UK Submission deadline: Friday 4th July, 2014 (submission instructions see below or workshop website) Workshop page: http://www.gesis.org/en/events/conferences/kmir2014/ Conference page: http://www.dl2014.org<http://www.dl2014.org/> Abstract: Knowledge maps are promising tools for visualizing the structure of large-scale information spaces, but still far away from being applicable for searching. The workshop aims at bringing together experts in IR and knowledge mapping in order to discuss the potential of interactive knowledge maps for information seeking purposes. Motivation, Goals, Objectives, Outcome The success of an information system depends mainly on its ability to properly support interaction between users and information. Current information systems, however, show as a particular point of failure the vagueness between user search terms and the knowledge orders of the information space in question (Mayr et al. 2008, Mutschke et al. 2011). Studies in interactive information seeking behavior have confirmed that the ability to browse an information space and observe similarities and dissimilarities between information objects is crucial for accidental encountering and the creative use of information (Nicholas et al. 2004, Westerman et al. 2005). This is in particular true for heterogeneous information spaces within the open web. Some kind of guided searching therefore becomes more and more important in order to precisely discover information without knowing the right search terms. Yet, this seems to remain the weakest point of interactive information systems (Ford 2000, Foster 2004, Tang 2007). Knowledge mapping encompasses all attempts to use visualizations to gain insights into the structure and evolution of large-scale information spaces. Knowledge maps can take the form of network visualizations, treemaps or specific, map like arrangements of search results (cf. Börner et al. 2003, Shiffrin/Börner 2004, Börner 2010, Klavans/Boyack 2010, Skupin et al. 2013, Sahal et al. 2013, Boyack/Klavans 2013). As an activity performed in very different disciplines - and often independent from each other - it stands in line with the dominance of the visual in our culture (Manovich 2009). Knowledge maps of digital library collections are promising navigation tools through knowledge spaces but - to the best of our knowledge - still far away from being applicable for searching digital libraries. Most maps are made for special purposes, are static, and usually not interactive (Akdag Salah et al. 2012). In interactive information systems the use of visual elements to enhance information seeking and discovery is a recurring research issue. However, not much of the experiences made in knowledge mapping have ever been implemented in online interfaces to digital libraries and collections (Börner/Chen 2001), nor is there a stable and continuous knowledge exchange between the "map makers" on the one hand and the Information Retrieval (IR) specialists on the other hand. Thus, there is also a lack of models that properly combine insights of the two strands, which are driven by quite different epistemic perspectives. Our workshop aims at bringing together these two communities: experts in IR reflecting on visual enhanced search interfaces and experts in knowledge mapping reflecting on visualizations of the content of a collection that might also present - visually - a context for a search term. The intention of the workshop is to raise awareness of the potential of interactive knowledge maps for information seeking purposes and to create a common ground for experiments aiming at the incorporation of knowledge maps into IR models at the level of the user interface. The major focus of the workshop is on the question of how knowledge maps can be utilized for scholarly information seeking in large information spaces. Our interests include interactive IR, information seeking behavior, knowledge mapping, science modelling, information visualization, and digital libraries. The workshop is closely related to the COST action KNOWeSCAPE (Analyzing the dynamics of information and knowledge landscapes: http://knowescape.org/<http://www.gesis.org/http:/>) which aims at implementing new navigation and search strategies based on insights of the complex nature of knowledge spaces as well as visualization principles for knowledge maps. The long-term research goal is to develop and evaluate new approaches for combining knowledge mapping and IR. More specifically, we address questions such as: * What are appropriate interactive knowledge maps for IR systems * How can knowledge maps be utilized for information seeking purposes? * How to locate an information need on a knowledge map? * How can (visually enhanced) search interfaces to knowledge maps look like? * How can interaction with knowledge maps be transformed into IR tasks? * Can knowledge maps improve searching in large, in particular heterogeneous, cross-language, cross-domain information spaces? * And the other way around: Can insights from IR also improve knowledge mapping itself? The availability of new IR test collections that contain citation and bibliographic information like the iSearch collection (see Lykke et al. 2010) or the ACL collection (Ritchie et al. 2006) could deliver an interesting playground for developing or evaluating combined models of IR and knowledge mapping for scholarly searching. Topical Outline To support the previously described goals the workshop topics include (but are not limited to) the following: * Knowledge maps for digital libraries * Knowledge orders of information spaces * Information seeking behaviour * Information discovery * Interactive IR systems * Human-computer IR * Knowledge Visualization in IR * Visual interfaces to information systems * Browsing and navigating information spaces * Task based user modelling, interaction and personalization * Evaluation of interactive IR systems. Types of Submissions * Full Papers (6 to 8 pages): Full papers, describing advanced or completed work * Short Papers (4 pages): Position papers or work in progress * Poster and Demonstrations (2 pages): Poster and Presentation of systems or prototypes All submissions must be written in English following the Springer LNCS Author Guidelines (http://www.springer.com/lncs) and should be submitted as PDF files to EasyChair: https://www.easychair.org/conferences/?conf=kmir2014.

Keynote at DL2014 workshop on Knowledge Maps and Information Retrieval (KMIR)
by Mutschke, Peter 04 Jun '14

04 Jun '14

We are pleased to announce the keynote speaker for the KMIR<http://www.gesis.org/en/events/conferences/kmir2014/> workshop on Knowledge Maps and Information Retrieval (to be held as part of the International Conference on Digital Libraries 2014<http://www.dl2014.org/>), London, 11th September: Dr. André Skupin (San Diego State University) will give a keynote talk on Managing Domain Knowledge: Ontology, Visualization, and Beyond. André Skupin<http://geography.sdsu.edu/People/Pages/skupin/> (Ph.D., University at Buffalo) is a Professor of Geography at San Diego State University. Areas of interest and expertise include geographic visualization, visual data mining, information visualization, and spatio-temporal modeling. Skupin's work has been strongly interdisciplinary, aimed at increased cross-fertilization between geography, information science, and computer science. It has been published in such diverse outlets as the Proceedings of the National Academy of Sciences, PLoS ONE, the Journal of Informetrics, and Pervasive and Mobile Computing. Aside from developing new methods for analyzing human mobility, demographic change, and environmental sensor data in n-dimensional attribute space, much of his research has addressed the question of how knowledge artifacts can be conceptualized and visualized. His approaches combine natural language processing and intense computation with geographic principles and cartographic techniques and have been applied to varied data sets, ranging from thousands of ICU medical records to tens of thousands of conference abstracts and millions of journal publications. André Skupin has served on the advisory board of the Places & Spaces project (http://scimaps.org/) since its inception, and currently serves on the Board of Directors of the University Consortium for Geographic Information Science (UCGIS). Abstract: Formal ontologies have become a standard staple of knowledge management, aiming to enumerate domain concepts and their relationships in a parsimonious manner amenable to digital storage and computational inference. This ontological approach is now converging with a long tradition of capturing domain knowledge in so-called Bodies of Knowledge (BoKs), in fields as diverse as project management, civil engineering, or business analysis. However, significant gaps remain when it comes to capturing the concepts and diverse practices of domain communities beyond giving voice to a small number of subject experts, as well as in envisioning the manner in which BoKs and ontologies can be usefully deployed. A team of researchers funded by the U.S. National Science Foundation recently developed a comprehensive approach to how a domain BoK could be conceptualized, collaboratively edited, stored, and visualized. Among the key proposals made is to turn a BoK from a hierarchically organized collection of domain topics into the foundation of an operational knowledge reference system. This in turn allows visualizations of the BoK to act as base maps supporting analytical operations inspired by geographic information systems (GIS). It then becomes possible to express relationships among domain artifacts (e.g., research articles, course syllabi, curricula vitae) and thereby among the actors and activities that produce and consume them, with natural language processing (NLP) playing a central role in operationalizing this vision. The resulting high-dimensional models of domain language can be leveraged within Web services and interactive visualizations, some of which will be featured in this presentation. Please remember the deadline for paper submissions: Friday 4th July, 2014 (see submission instructions on workshop website: http://www.gesis.org/en/events/conferences/kmir2014/) Kind regards, Peter Mutschke --- Acting Head of Department Dep.
