Expert-driven business process management is an establishedmeans for improving efficiency of organizational knowledge work.Implicit procedural knowledge in the organization is made explicit bydening processes. This approach is not applicable to individual knowledgework due to its high complexity...

We present a non-linear camera pose estimator, which is able to handle a combined input of point and line featurecorrespondences. For three or more correspondences, the estimator works on any arbitrary number and choiceof the feature type, which provides an estimation of the pose on a preferably...

Eye-trackers have been used in the past to identify visual foci inimages, nd task-related image regions, or localize aective regions inimages. However, they have not been used for identifying specic ob-jects in images. In this paper, we investigate whether it is possibleto assign image regions...

We present the user-centered, iterative design of Mobile Facets, a mo-bile application for the faceted search and exploration of a large, multi-dimensional data set of social media on a touchscreen mobile phone. Mo-bile Facets provides retrieval of resources such as places, persons,...

One of the key factors that hinders integration of distributed, heterogeneousinformation systems is the lack of a formal basis for modeling the complex, structuredknowledge that is to be exchanged. To alleviate this situation, we present anapproach based on core ontologies. Core ontologies are...

This paper has a twofold concern. First, to show that probabilitypropagation nets (PPNs) can be derived from formulae for conditionalprobabilities. Second, to show that PPNs are usable for (local)propagations of mass distributions, too, if the inscriptions are suitablyadapted.[...]

Knowledge compilation is a common technique for propositionallogic knowledge bases. A given knowledge base is transformedinto a normal form, for which queries can be answered efficiently. Thisprecompilation step is expensive, but it only has to be performed once.We apply this technique to...

In vielen Köpfen – sowohl bei Erwachsenen wie auch bei Schülern – geistert der Glaube, dassInformatik die Wissenschaft der „Computerlehre“ ist. Schon der berühmte Satz „In derInformatik geht es genauso wenig um Computer wie in der Astronomie um Teleskope“, derdem Informatiker...

In dieser Arbeit wird ein Datenmodell für Shared Annotationsvorgestellt. Basierend auf einem bereits existierenden Datenmodell fürAnnotationen, wird dieses erweitert um die Möglichkeit der Modellierung vonShared Annotations. Daraufhin werden Funktionen von Shared Annotationserläutert, die...

Ontologies play an important role in knowledge representationfor sharing information and collaboratively developing knowledgebases. They are changed, adapted and reused in different applicationsand domains resulting in multiple versions of an ontology. The comparisonof different versions and the...
