The path of least resistance

Manuel Müller, Christina Ohm, Florin Schwappach, Bernd Ludwig

KI - Künstliche Intelligenz > 2017 > 31 > 2 > 125-134

Several studies show that pedestrians do not simply take the shortest route to their destination. In this paper, we address the question, which other factors influence their route decisions. We present a landmark based pedestrian navigation system that guides users through indoor and outdoor areas and forms the foundation of our research regarding route preferences. To investigate the issue which...

Context-Based Routing in Dynamic Networks

Bernd-Ludwig Wenning, Vieweg+Teubner

Routing in dynamically changing networks is a challenge, especially when the current context, usually consisting of multiple criteria, is used as a quality measure and decision metric. Bernd-Ludwig Wenning presents a context-based routing framework which can be applied to routing in different application domains. The routing framework includes the signaling as well as a decision system that is applied...

RLL - reliable low latency broadcast data dissemination in dense wireless lighting control networks

Conrad Dandelski, Bernd-Ludwig Wenning, Michael Kuhn, Dirk Pesch

2016 IEEE 21st International Conference on Emerging Technologies and Factory Automation (ETFA) > 1 - 8

2016 IEEE 21st International Conference on Emerging Technologies and Factory Automation (ETFA)

The increased introduction of individually wirelessly controlled LED light sources in conjunction with the need to retrofit those into existing buildings often leads to very dense wireless lighting networks. Current approaches for control message transmission in such systems are based on broadcasting messages among the many luminaires. However, adequate communication performance, in particular, sufficiently...

Analysis of fMRI images with bi-dimensional empirical mode decomposition based-on Green's functions

Saad Al-Baddai, Karema Al-Subari, Ana Maria Tomé, Bernd Ludwig, more

Biomedical Signal Processing and Control > 2016 > 30 > C > 53-63

We present a new method for decomposing two-dimensional data arrays with empirical mode decomposition (EMD). It performs envelope surface interpolation based on Green's functions in tension (GiT) to extract bi-dimensional intrinsic mode functions (BIMFs). The new method is called GiT-BEMD and outperforms existing bi-dimensional ensemble EMD (BEEMD) variants in terms of computational costs and quality...

Martin Atzmueller, Tom Hanika, Gerd Stumme, Richard Schaller, more

2016 IEEE/ACM International Conference on Advances in Social Networks Analysis and Mining (ASONAM) > 613 - 620

2016 IEEE/ACM International Conference on Advances in Social Networks Analysis and Mining (ASONAM)

This paper focuses on the analysis of socio-spatial data, i. e., user-performance relations at a distributed event. We consider the data as a bimodal network (i. e., model it as a bipartite graph), and investigate its structural characteristics towards a social network. We focus on plans of the participants (expressed by preferences) and their fulfilment, and propose measures for matching preference...

A Pragmatics-First Approach to the Analysis and Generation of Dialogues

Bernd Ludwig

Lecture Notes in Computer Science > KI 2004: Advances in Artificial Intelligence > Natural Language Processing > 82-96

Integration of new utterances into context is a central task in any model for rational (human-machine) dialogues in natural language. In this paper, a pragmatics-first approach to specifying the meaning of utterances in terms of plans is presented. These plans are computed during a dialogue on the basis of information about the current situation that is updated continually. New contributions are integrated...

Context-Aware Places of Interest Recommendations for Mobile Users

Linas Baltrunas, Bernd Ludwig, Stefan Peer, Francesco Ricci

Lecture Notes in Computer Science > Design, User Experience, and Usability. Theory, Methods, Tools and Practice > DUXU in the Mobile and Vehicle Context > 531-540

Recommender Systems (RSs) are software tools and techniques providing suggestions for items, such as movies, CDs, or travels, to be of use to a user. In general, a recommendation can be more compelling and useful if the context of the user is known. For instance, in a travel recommender, the season of the travel, or the group composition, or the motivation of the travel are all important contextual...

The state of association of the cytochrome bc₁ complex from Paracoccus denitrificans in solutions of dodecyl maltoside

Gottfried Mayer, Oliver Anderka, Bernd Ludwig, Dieter Schubert

Progress in Colloid and Polymer Science > Analytical Ultracentrifugation VI > Interacting Systems > 77-83

The cytochrome bc₁ complex is an intrinsic membrane protein of many respiratory chains. We studied the association state of solubilized cytochrome bc₁ from Paracoccus denitrificans by sedimentation equilibrium experiments in the analytical ultracentrifuge. Since the stability of the solubilized complex was only maintained in solutions containing low concentrations of the nonionic detergent n-dodecyl-...

Multi-context Systems with Activation Rules

Stefan Mandl, Bernd Ludwig

Lecture Notes in Computer Science > KI 2010: Advances in Artificial Intelligence > Knowledge > 135-142

Multi-Context Systems provide a formal basis for the integration of knowledge from different knowledge sources. Yet, it is easy to conceive of applications where not all knowledge sources may be used together all the time. We present a natural extension of Multi-Context Systems by adding the notion of activation rules that allows modeling the applicability or relevance of contexts depending on beliefs...

A contribution to the question of authenticity of Rhesus using part-of-speech tagging

Bernd Ludwig

Lecture Notes in Computer Science > KI-97: Advances in Artificial Intelligence > 231-242

This paper presents the results of an experiment to decide the question of authenticity of the supposedly spurious Rhesus—a attic tragedy sometimes credited to Euripides. The experiment involves the use of statistics in order to test whether significant deviations in the distribution of word categories between Rhesus and the other works of Euripides can or cannot be found. To count frequencies of...

Ambiguity Reports for Flexible Dialog Management

Kerstin Bücher, Michael Knorr, Bernd Ludwig

Lecture Notes in Computer Science > Advances in Natural Language Processing > Natural Language Interfaces and Dialogue Systems > 151-160

The ability to react flexibly on misunderstandings between user and system is an important factor for the acceptance of spoken dialog systems. This paper addresses the issue of grounding utterances in task-oriented human-computer dialogs. It focuses on the aspect of handling ambiguities while parsing output from a speech recognizer: The parser detects the origin and the type of ambiguities which are...

Coping with Unconsidered Context of Formalized Knowledge

Stefan Mandl, Bernd Ludwig

Lecture Notes in Computer Science > Modeling and Using Context > 342-355

The paper focuses on a difficult problem when formalizing knowledge: What about the possible concepts that didn’t make it into the formalization? We call such concepts the unconsidered context of the formalized knowledge and argue that erroneous and inadequate behavior of systems based on formalized knowledge can be attributed to different states of the unconsidered context; either while formalizing...

Hybrid Natural Language Generation in a Spoken Language Dialog System

Martin Klarner, Bernd Ludwig

Lecture Notes in Computer Science > KI 2004: Advances in Artificial Intelligence > Natural Language Processing > 97-111

Natural Language Generation (NLG) systems have almost reached the state of “market-readiness” now, mostly because hybrid systems of different types have emerged as a de-facto standard. But still relatively few dialog systems make use of NLG techniques. In this paper, we discuss the output part of our spoken language dialog system by presenting an example scenario including dialog management,...

Static Preference Models for Options with Dynamic Extent

Thomas Bauereiß, Stefan Mandl, Bernd Ludwig

Lecture Notes in Computer Science > KI 2010: Advances in Artificial Intelligence > Human-Machine Interaction > 99-106

Models of user preferences are an important resource to improve the user experience of recommender systems. Using user feedback static preference models can be adapted over time. Still, if the options to choose from themselves have temporal extent, dynamic preferences have to be taken into account even when answering a single query. In this paper we propose that static preference models could be used...

Analytical Examination of Route Discovery Traffic

Bernd-Ludwig Wenning

Context-Based Routing in Dynamic Networks > 57-76

The task of finding an optimal path with respect to multiple criteria, as it is intended in the proposed context-based routing, can be categorised in the category of socalled Multi-Constrained Path (MCP) problems.

Vehicle and Commodity Flow Synchronization

Jörn Schönberger, Herbert Kopfer, Bernd-Ludwig Wenning, Henning Rekersbrink

Operations Research Proceedings 2008 > Traffic and Transportation > 307-312

Summary Network freight ow consolidation organizes the commodity ow with special attention to the minimization of the ow costs but the efficiency of transport resources is not addressed. In contrast, vehicle routing targets primarily the maximization of the efficiency of transport resources but the commodity-related preferences are treated as inferior requirements. This article is about the problem...
