In this chapter we describe an e-Tourism environment that places emphasis on a community-driven approach to foster a lively society of travelers. It enables them to exchange travel experiences, recommend tourism destinations or just catch some interesting gossip. Moreover, business transactions such as booking a trip or getting assistance from professional(More)
— We establish the optimal diversity-multiplexing (DM) tradeoff of coherent selective-fading multiple-access multiple-input multiple-output (MIMO) channels and provide corresponding code design criteria. As a byproduct, on the conceptual level, we find an interesting relation between the DM tradeoff framework and the notion of dominant error event regions(More)
We establish the optimal diversity-multiplexing (DM) tradeoff for coherent selective-fading multiple-access MIMO channels and provide corresponding code design criteria. As a byproduct, on the conceptual level, we find an interesting relation between the DM tradeoff framework and the notion of dominant error event regions, first introduced in the AWGN case(More)
● Task focused user interfaces (tool specific, search and exploration) ● Extensible plugin architecture ● Integrates with automatic processing tools (e.g. mate-tools [Bohnet, 2010]) ● Remote Tools (Webservices of the German CLARIN-D Initiative) ● Utility Tools for various formats (CoNLL and TCF) ● Export graphs to various formats (*.png , *.svg and *.xml) ●(More)
We present the ICARUS Coreference Explorer , an interactive tool to browse and search coreference-annotated data. It can display coreference annotations as a tree, as an entity grid, or in a standard text-based display mode, and lets the user switch freely between the different modes. The tool can compare two different annotations on the same document,(More)
—3D Virtual Worlds have the potential to expand the knowledge of a foreign culture by presenting the information in a visual context. In this paper we describe the design and evaluation of ICURA, a Serious Game that provides an opportunity to learn more about Japanese culture and etiquette. ICURA incorporates different game design and learning principles to(More)
3D Electronic Institutions integrate a multi-agent system methodology for arbitrary e-Commerce applications with immersive collaborative 3D environments. This approach facilitates the development of the social and immersive 3D e-Tourism Environment "itchy feet" with the principal goal of developing an instrument to support the complex interaction patterns(More)
We present an error mining tool that is designed to help human annotators to find errors and inconsistencies in their annotation. The output of the underlying algorithm is accessible via a graphical user interface, which provides two aggregate views: a list of potential errors in context and a distribution over labels. The user can always directly access(More)
