What is Wrong with Digital Documents? A Conceptual Model for Structural Cross-Media Content Composition and Reuse

While such a paper simulation might be appropriate for the visualisation of certain digital content, it is generally not the most effective solution for digitally managing and storing information. The oversimplistic modelling of digital documents as monolithic blocks of linear content, with a lack of structural semantics, does not pay attention to some of the superior features that digital media offers in comparison to traditional paper documents. For example, existing digital document formats adopt the limitations of paper documents by unnecessarily replicating content via copy and paste operations, instead of digitally embedding and reusing parts of digital documents via structural references. We introduce a conceptual model for structural cross-media content composition and highlight how the proposed solution not only enables the reuse of content via structural relationships, but also supports dynamic and context-dependent document adaptation, structural content annotations as well as the integration of arbitrary non-textual media types. We further discuss solutions for the fluid navigation and cross-media content publishing based on the proposed structural cross-media content model.

Interactive Paper: Past, Present and Future

While recent technological developments enable new forms of paper-digital integration and interaction, some of the original research on interactive paper dates back almost twenty years. We give a brief overview of the most relevant past and current interactive paper developments. Then, based on our experience in developing a wide variety of interactive paper solutions over the last decade, as well as the results of other research groups, we outline future directions and challenges for the realisation of innovative interactive paper solutions. Further, we propose the definition of common data formats and interactive paper design patterns to ensure future cross-application and framework interoperability.

Phases and Lssues In the Transition to ETDs

Four phases are identified in this process: exploration, experimentation, transition, and institutionalization. Other chapters in this volume address technical aspects of ETDs. Thus, recommendations are not made in this chapter regarding details of ETD submissions, file formats, and the like. Rather this chapter addresses the process of investigation and adoption of ETDs at a university and presents an itinerary of issues that are likely to arise along the way. We hope that this discussion will be useful to those beginning an exploration into ETDs as a possible medium for theses and dissertations.

Enhancing Information Search by Utilizing Mind Maps

In addition, we briefly present the first research results which indicate that mind maps can be used to determine document relatedness and therefore can enhance document recommender systems. We also discuss some challenges that information retrieval on mind maps will probably have to overcome.

Google Scholar’s Ranking Algorithm: The Impact of Articles’ Age (An Empirical Study)

In recent studies we partly reverse-engineered the algorithm. This paper presents the results of our third study. While the first study provided a broad overview and the second study focused on researching the impact of citation counts, the current study focused on analyzing the correlation of an article’s age and its ranking in Google Scholar. In other words, it was analyzed if older/recent published articles are more/less likely to appear in a top position in Google Scholar’s result lists. For our study, age and rankings of 1,099,749 articles retrieved via 2,100 search queries were analyzed. The analysis revealed that an article’s age seems to play no significant role in Google Scholar’s ranking algorithm. It is also discussed why this might lead to a suboptimal ranking.

Our results show, it is possible: We ‘improved’ the ranking of articles by manipulating their citation counts and we made articles appear in searchers for keywords the articles did not originally contained by placing invisible text in modified versions of the article.

Towards Query by Sketch

However, such queries require that one or even several reference images are available prior to the start of the search process. These reference images must be close to the final result so that the user can take them to express her information need. If such reference images are not available or if the information need is covered only by parts of the query object, the result usually does not meet the user’s expectation. Therefore, more flexible user interfaces are needed that allow users to sketch a query image by hand drawings and to dynamically select regions of interest from a given query image. In this paper, we present a novel approach to query by sketch where interactive paper and image similarity search are seamlessly combined. It is based on the iPaper/iServer system of ETH Zurich and the ISIS/OSIRIS content-based image retrieval system of the University of Basel. The paper presents the integrated system which has already very successfully been applied to the development of an interactive museum catalogue. Moreover, it reports on ongoing activities that aim at extending the system to support handwritten sketches, gestures and/or dynamic region selection to make the retrieval process more flexible and less dependent from existing query objects.
