Integrating and accessing structured textual content obtained from different sources is a challenging task and becomes even more so when dealing with multiple languages. The objective of this article is to showcase the technological efforts towards the creation of a digital European history textbook repository that integrates respective textbooks from various countries and publishers. The content integration is achieved by introducing language independent metadata based on space (locations), time (dates), and thematic categories (history gazetteer). Providing adequate interfaces such metadata can be used to offer language-independent access to Multilanguage history textbook content. The specific focus in this article will be on (1) presenting the metadata, (2) the data management approach including indexing the history textbook content and (3) the resulting textbook repository including its GIS-based interface, allowing for a combination of map, timeline and keyword based search of the history content. © 2010 Blackwell Publishing Ltd.

In the early stages of the introduction of an Information System in a Hospital and before the initiation of the procedures for the actual installation, numerous preparatory actions must be concluded as part of the project. The set of these actions comprise a certain preparatory phase which must be considered part of the project and it has to be well suited in the initial plans. Omitting or limiting the preparatory phase will have as a consequence noticeable delays and in some cases the failure of modules or even endanger the entire project. The successful completion of the preparatory actions rely on a systematic approach which ensures that all the influencing factors have been considered and all interacting conflicts have been resolved prior to the project's commencement; this can be realized by employing a methodological framework such as the 4-by-3 structure with shafts, which is proposed in the present paper. The considered preparations provide a clear picture and a feedback of the existing organizational readiness and the necessary existing IT cultural status, thus allow taking in advance, the appropriate and adequate measures. © 2010 International Federation for Medical and Biological Engineering.

Mobile devices are a promising platform for content delivery considering the (i) variety of attached sensors, (ii) widespread availability of wireless networks, (iii) even increasing screen estate and hardware specs. What has been missing so far is the adequate coupling of content to those devices and their users' actions. This is especially apparent in the area of Location-based Services (LBS), which, with few exceptions (e.g., navigation), have not fulfilled their predicted commercial success in mobile environments due to the following reasons: (i) content in typical LBS applications is still narrow and static, (ii) available methods and interfaces in mobile handsets for the discovery of available content are at best cumbersome (e.g., keyword-type search), and (iii) existing structured content available in LBS applications is hard to reuse. In this work, we propose the concept of task computing to complement and extend LBS as a means to enable the intuitive and efficient re-purpose, discovery, and delivery of rich content according to the user's needs. Further, we establish the theoretical foundations of task computing and its application in the LBS domain. We also present a fully functional prototype iPhone application structured around the concept of task computing. © 2011 Springer-Verlag. Source
