  abstract     = {{In this paper we present LimesWebUI, our web interface of Limes. Limes, the Link Discovery Framework for Metric Spaces, is a framework for dis- covering links between entities contained in Linked Data sources. LimesWebUI assists the end user during the link discovery process. By representing the link specifications (LS) as interlocking blocks, our interface eases the manual creation of links for users who already know which LS they would like to execute. How- ever, most users do not know which LS suits their linking task best and therefore need help throughout this process. Hence, our interface provides wizards which allow the easy configuration of many link discovery machine learning algorithms, that does not require the user to enter a manual LS. We evaluate the usability of the interface by using the standard system usability scale questionnaire. Our over- all usability score of 76.5 suggests that the online interface is consistent, easy to use, and the various functions of the system are well integrated.}},

  abstract     = {{An increasing number of heterogeneous datasets abiding by the Linked Data paradigm is published everyday. Discovering links between these datasets is thus central to achieving the vision behind the Data Web. Declarative Link Discovery (LD) frameworks rely on complex Link Specification (LS) to express the conditions under which two resources should be linked. Complex LS combine similarity measures with thresholds to determine whether a given predicate holds between two resources. State of the art LD frameworks rely mostly on string-based similarity measures such as Levenshtein and Jaccard. However, string-based similarity measures often fail to catch the similarity of resources with phonetically similar property values when these property values are represented using different string representation (e.g., names and street labels). In this paper, we evaluate the impact of using phonetics-based similarities in the process of LD. Moreover, we evaluate the impact of phonetic-based similarity measures on a state-of-the-art machine learning approach used to generate LS. Our experiments suggest that the combination of string-based and phonetic-based measures can improve the Fmeasures achieved by LD frameworks on most datasets.}},

Discovering links between these datasets is thus central to achieve the vision behind the Data Web. Declarative Link Discovery (LD) frameworks rely on complex Link Specification (LS) to express the conditions under which two resources should be linked. Understanding such LS is not a trivial task for non-expert users, particularly when such users are interested in generating LS to match their needs. Even if the user applies a machine learning algorithm for the automatic generation of the required LS, the challenge of explaining the resultant LS persists. Hence, providing explainable LS is the key challenge to enable users who are unfamiliar with underlying LS technologies to use them effectively and efficiently. In this paper, we address this problem by proposing a generic approach that allows a LS to be verbalized, i.e., converted into understandable natural language. We propose a summarization approach to the verbalized LS based on the selectivity of the underlying LS. Our adequacy and fluency evaluations show that our approach can generate complete and easily understandable natural language descriptions even by lay users.}},

  abstract     = {{Point of Interest (POI) data constitute the cornerstone of any application, service or product even remotely related to our physical surroundings. From navigation applications to social networks, tourism, and logistics, we use POI data to search, communicate, decide and plan our actions. POIs are semantically diverse and spatio-temporally evolving entities, having geographical, temporal and thematic relations. Currently, integrating POI data to increase their coverage, timeliness, accuracy and value is a resource-intensive and mostly manual process, with no specialized software available to address the specific challenges of this task. In this paper, we present an integrated toolkit for transforming, linking, fusing and enriching POI data, and extracting additional value from them. In particular, we demonstrate how Linked Data technologies can address the limitations, gaps and challenges of the current landscape in Big POI data integration. We have built a prototype application that enables users to define, manage and execute scalable POI data integration workflows built on top of state-of-the-art software for geospatial Linked Data. The application abstracts and hides away the underlying complexity, automates quality-assured integration, scales efficiently for world-scale integration tasks and lowers the entry barrier for end-users. Validated against real-world POI datasets in several application domains, our system has shown great potential to address the requirements and needs of cross-sector, cross-border and cross-lingual integration of Big POI data.}},

  abstract     = {{<jats:p>The article analyzes how an emerging form of automation may drastically transform contemporary employment dynamics. Recent breakthroughs in the field of artificial intelligence (AI) make it possible to automate both manual and mental non-standard tasks. The first part of the article traces the development of AI. Whereas classical algorithms required the creation of a hermetic environment for AI to thrive, modern neural network-based AI is capable of surviving in the chaotic realm occupied by humans. Based on an analysis of changes in the nature of AI, the authors distinguish between substitutive and supplemental automation. The former refers to a complete replacement of humans by machines, while the latter indicates a selective substitution of humans in specific professional functions. In order to conceptualize professions as a nexus of automatable components, the authors employ Goffman’s dramaturgical framework. Goffman studied the social visibility of professional activity. Goffman held that any profession can be divided into invisible routines that are fundamental to it and a dramatization that makes the profession socially visible. The article demonstrates that the current utopian and antiutopian views of automation both reduce work to its visible components and neglect the logic of supplemental automation. The authors argue that the targets of modern automation are not the socially visible components but the invisible routines. In the final section, the authors develop a model that takes these invisible professional routines into account and analyze what effect this new type of automation may have on different types of professions with differing degrees of social visibility.</jats:p>}},

  abstract     = {{<jats:title>ABSTRACT</jats:title><jats:p>Drawing on the political theory of judicial decision making, our paper proposes a new and parsimonious ex ante litigation risk measure: federal judge ideology. We find that judge ideology complements existing measures of litigation risk based on industry membership and firm characteristics. Firms in liberal circuits (the third quartile in ideology) are 33.5% more likely to be sued in securities class action lawsuits than those in conservative circuits (the first quartile in ideology). This result is stronger after the U.S. Supreme Court's ruling in the <jats:italic>Tellabs</jats:italic> case. We next show that the effect of judge ideology on litigation risk is greater for firms with more sophisticated shareholders and with higher expected litigation costs. Furthermore, judicial appointments affect litigation risk and the value of firms in the circuit, highlighting the economic consequences of political appointments of judges. Finally, using our new measure, we document that litigation risk deters managers from providing long‐term earnings guidance, a result that existing measures of litigation risk cannot show.</jats:p>}},

  abstract     = {{Durch die Auslegung eines Fahrwerks werden maßgebend die Fahrsicherheit, der Fahrkomfort, die Effizienz und der Fahrspaß eines Kraftfahrzeugs bestimmt. Daher zählt das Fahrwerk zu den wichtigsten und zugleich komplexesten Systemen in einem Automobil. Aufgrund steigender Kundenanforderungen, Auflagen durch Gesetzgebung sowie Termin- und Kostendruck stellt die Entwicklung des Fahrwerks für die heutigen Automobile stets eine Herausforderung dar. Um die gestellten Anforderungen zu erfüllen, sind oftmals gegenläufige Maßnahmen erforderlich, sodass die Auslegung des Fahrwerks in der Regel nur einen Kompromiss bildet. Entwicklungsziele zur Reduktion der Umweltbelastung und zur Effizienzsteigerung gewinnen hierbei zunehmend an Bedeutung. Damit verbunden müssen die Interaktionen zwischen Fahrwerk und Reifen hinreichend genau erfasst werden, sodass folglich eine Erweiterung bisheriger Simulationsmethoden erforderlich ist. In der vorliegenden Arbeit wird eine Vorgehensweise mit dem Schwerpunkt auf der Abbildung der Wechselwirkungen zwischen der Fahrwerkdynamik am Beispiel einer Mehrlenkerhinterachse und des Reifen-Fahrbahn-Rollkontakts entwickelt, die eine modellbasierte Analyse der Reibvorgänge in der Kontaktzone unter realitätsnahen Bedingungen ermöglicht. Vor allem können dadurch die Auswirkungen der Fahrwerkauslegung auf die Leistungsübertragung zwischen Reifen und Fahrbahn und den resultierenden Reifenverschleiß effektiv bewertet und bereits in der frühen Entwicklungsphase berücksichtigt werden.}},

Die typisch angewandten Verfahren zur Schwingungsmessung solcher Strukturen legen in der Regel ein lineares Strukturverhalten zu Grunde, oder sie erfordern einen hohen Zeit- und Messaufwand für die Abbildung des nichtlinearen Verhaltens; häufig in Verbindung mit einer starken Belastung der zu testenden Struktur. Die Bestimmung nichtlinearen Strukturverhaltens ist somit oft nicht effizient realisierbar. In der vorliegenden Arbeit wird ein neuer Ansatz zur Schwingungsanalyse nichtlinearer Strukturen mit von der Anregungsamplitude abhängigem Übertragungsverhalten vorgestellt. Dabei liegt ein Schwerpunkt auf der messtechnischen Bestimmung des nichtlinearen Verhaltens bei deutlich reduziertem Zeit- bzw. Messaufwand. Das Verfahren basiert auf einer Messmethode, die eine effiziente Bestimmung des nichtlinearen Kennfeldes der analysierten Struktur mit speziellen multiharmonischen Anregungssignalen ermöglicht. In Kombination mit einem fortschrittlichen Auswertealgorithmus kann eine vollständige Beschreibung des dynamischen Verhaltens in Form eines charakteristischen Diagramms generiert werden.

Die Betriebsparamter der Ultraschallsysteme werden empirisch ermittelt, da derzeit keine systematische Analyse der Wechselwirkung zwischen Ultraschallwandler und Schallfeld sowie kein Verfahren zur Messung der Kavitationsaktivität ohne zusätzlichen Sensor existieren. Auf Basis einer experimentellen Analyse des betrachteten sonochemischen Reaktors wird ein Finite-Elemente-Modell aufgebaut, das die Wechselwirkung zwischen Schallfeld und Ultraschallwandler berücksichtigt. Die modellbasierte Analyse zeigt, dass wegen der akustischen Eigenschaften des Autoklavs nur direkt an der Sonotrode Kavitation entsteht. Die Wechselwirkung zwischen Ultraschallwandler und Schallfeld ermöglicht Aussagen über das Schallfeld und die Kavitationsaktivität auf Basis der Rückwirkung auf den Ultraschallwandler. Die lineare Schalldruckverteilung ermöglicht eine Prognose über die Verteilung von Kavitationszonen. Das beschriebene Modell liefert wertvolle Erkenntnisse für die Auslegung, Analyse und Skalierung sonochemischer Reaktoren. Auf Grund der rauen Prozessrandbedingungen ist die Applikation von Sensoren zur Überwachung der Kavitationsaktivität in vielen sonochemischen Prozessen nicht möglich. Zur prozessbegleitenden Messung der Kavitationsaktivität wird ein Verfahren entwickelt, das die Bewertung der Kavitationsaktivität durch Auswertung der Rückwirkung auf den Ultraschallwandler erlaubt.
