Successful Presentation of Digipen Software for Customer Consultants

From November 13th to 15th 2012, the Digipen Software for Customer Consultants of Savings Banks has been presented at the inhouse exhibition "Finanzinformatik für Sparkassen" hosted by the Finanzinformatik (FI) institute. The concept of the Digipen Software was created by the DFKI and has been developed in a joint project together with Ventuno and Bend-IT. The Anoto-based Digipen Software is the first accredited solution for recording, law compliant storage and verification of legally binding customer signatures on contracts and was considered one of the top three most successful innovations of the whole exhibition.

The first Instance of Digipen was rolled out in October 2012 and operates very reliably since then. During the exhibition, roughly 100 other institutes signalled their interest in this solution which opened up a completely new market.

 

Presentation of Museum Guide 2.0 at Night of Science

The DFKI has opened its doors for the public during the Night of Science (Nacht der Wissenschaft) on November 9th, 2012 to present highlights of their latest research results. Amongst the presented system the Museum Guide 2.0 (MG20) could have been tried out by the public. MG20 can be described as the next generation audio guide for museum visitors. It automatically detects, if a visitor looks at an object with interest and triggers the output of the classical audio guide information via earphones. No explicit user action is required.

The technological basis for this system is a head mounted eye tracker which records the scenerey the users head points to and which identifies the position within the image to which the user gaze is directed. The device used for the demonstrations - the model ETG from SMI (http://www.smivision.com/) represents the cutting edge in integrated mobile eye trackers: tracking of both eyes for a maximum reliability, 1-point calibration, HD-scene camera - and all integrated within a spectacle frame.

DFKI has integrated different specialized algorithms for image based retrieval to match the gazed object against a reference library and to distinguish unconscious from conscious gaze. In the latter case, augmented reality information (like the audio guide output) can be triggered. The visitors who could try out this fully automatic system, were generally impressed by the subjective accuracy of the system. Further information on MG20 can be found here: http://museum20.dfki.de/

The demonstration at the night of science as well as ongoing evaluations of MG20 are kindly supported by the "Museum Pfalzgalerie Kaiserslautern" (http://www.mpk.de/).

Semantische Technologien
Grundlagen. Konzepte. Anwendungen.

Dieses Lehrbuch bietet eine umfassende Einführung in Grundlagen, Potentiale und Anwendungen Semantischer Technologien. Es richtet sich an Studierende der Informatik und angrenzender Fächer sowie an Entwickler, die Semantische Technologien am Arbeitsplatz oder in verteilten Applikationen nutzen möchten.

Mit seiner an praktischen Beispielen orientierten Darstellung gibt es aber auch Anwendern und Entscheidern in Unternehmen einen breiten Überblick über Nutzen und Möglichkeiten dieser Technologie. Semantische Technologien versetzen Computer in die Lage, Informationen nicht nur zu speichern und wieder zu finden, sondern sie ihrer Bedeutung entsprechend auszuwerten, zu verbinden, zu Neuem zu verknüpfen, und so flexibel und zielgerichtet nützliche Leistungen zu erbringen.

Das vorliegende Buch stellt im ersten Teil die als Semantische Technologien bezeichneten Techniken, Sprachen und Repräsentationsformalismen vor. Diese Elemente erlauben es, das in Informationen enthaltene Wissen formal und damit für den Computer verarbeitbar zu beschreiben, Konzepte und Beziehungen darzustellen und schließlich Inhalte zu erfragen, zu erschließen und in Netzen zugänglich zu machen.
Der zweite Teil beschreibt, wie mit Semantischen Technologien elementare Funktionen und umfassende Dienste der Informations- und Wissensverarbeitung realisiert werden können. Hierzu gehören etwa die Annotation und das Erschließen von Information, die Suche in den resultierenden Strukturen, das Erklären von Bedeutungszusammenhängen sowie die Integration einzelner Komponenten in komplexe Ablaufprozesse und Anwendungslösungen.
Der dritte Teil beschreibt schließlich vielfältige Anwendungsbeispiele in unterschiedlichen Bereichen und illustriert so Mehrwert, Potenzial und Grenzen von Semantischen Technologien. Die dargestellten Systeme reichen von Werkzeugen für persönliches, individuelles Informationsmanagement über Unterstützungsfunktionen für Gruppen bis hin zu neuen Ansätzen im Internet der Dinge und Dienste, einschließlich der Integration verschiedener Medien und Anwendungen von Medizin bis Musik.

A Collaborative Knowledge Management Approach to Provide Better Agricultural Decision Support

According to the Food and Agriculture Organization of the United Nations, with the world population projected to surpass 9 billion people by 2050, agriculture is facing huge challenges in providing enough food to the extra two billion people, and although increasing the agricultural food production in the past has been mostly done by increasing the surface or arable land, 90 percent of the extra production in industrial countries must be achieved through higher crop yields alone.

The agricultural sector is highly competitive and farmers not only have to consider agricultural and ecological but also economical and political factors. In Europe, public agricultural institutions provide farmers with the necessary decision support to help them optimize their production while considering those factors. To further improve the crop yields, forecasts need to be more accurate and geographically more differentiated to reveal local optimization opportunities. However, public agricultural institutions are currently facing critical knowledge management issues in the development and the maintenance of these decision support tools, which prevent them from providing more accurate forecasts.

The aim of this thesis is to make a contribution to fighting world hunger by supporting the development of better agricultural decision support tools to help farmers increase their crop yields. I analyze the current knowledge issues between public agricultural institutions and farmers and show that these institutions lack the required accurate geo-data to provide farmers with better decision support, but also that farmers could potentially contribute to the acquisition of this geo-data.
