Clinical trial data requires a lot of processing before it can be submitted in accordance with its standardization requirements. After its processing, data has to be stored carefully, often in different systems and formats. Integrating this data without information loss and enabling easy retrieval for later analysis is a highly challenging task. In...

Collaborative vocabulary development in the context of data integration is the process of finding consensus between experts with different backgrounds, system understanding and domain knowledge. The complexity of this process increases with the number of people involved, the variety of the systems to be integrated and the dynamics of their domain....

Vocabularies are increasingly being developed on platforms for hosting version-controlled repositories, such as GitHub. However, these platforms lack important features that have proven useful in vocabulary development. We present VoCol, an integrated environment that supports the development of vocabularies using Version Control Systems. VoCol is...

The complexity of this process is increased with the number of involved people, the variety of the systems to be integrated and the dynamics of their domain. In this paper we advocate...

Advanced, highly specialized economies require instant , robust and efficient information flows within its value-added and Supply Chain networks. Especially also in the context of the recent Industry 4.0, smart manufacturing or cyber-physical systems initiatives more efficient and effective information exchange in supply networks is of paramount im...

In the engineering and manufacturing domain, there is currently an atmosphere of departure to a new era of digitized production. In different regions, initiatives in these directions are known under different names, such as industrie du futur in France, industrial internet in the US or Industrie 4.0 in Germany. While the vision of digitizing produc...

A major bottleneck for a wider deployment and use of ontologies and knowledge engineering techniques is the lack of established conventions along with cumbersome and inefficient support for vocabulary and ontology authoring. We argue, that the pragmatic development by convention paradigm well-accepted within software engineering, can be successfull...

Durch den Erfolg des mobilen Internets werden Mobilfunknetzanbieter zunehmend zu sogenannten Bit Pipes degradiert, deren Anteil am Gesamtvolumen des Dienstmarktes im Vergleich zu anderen Dienstanbietern gering ausfällt. Um dem entgegenzuwirken, wird in diesem Kapitel die Verwertung des immensen Datenaufkommens der Mobilfunknetze mithilfe von semant...

This work presents a new approach to ensure compliance to legal regulation in Cloud Computing, especially in Software-as-a-Service. Since high demanding business sectors, such as the health care sector, require high legal certainty, when contracting services offered by external providers. We provide a lightweight ontological representation of the G...

In the field of software engineering component-based development and appropriate documentation are established methods to support reuse. While modular development is tackled in various work regarding ontology engineering, it is an open problem how documentation of ontologies should be created. After analyzing existing ontology documentations we ide...

Reusing existing Semantic Web ontologies is necessary to avoid heterogeneity as well as redundant modeling efforts, because ontology engineering is a time-consuming and cost-intensive task. In order to decide whether a candidate ontology comprises the right concepts, an analysis process is necessary to understand the conceptual model of the ontolog...

Das Verwalten, Aggregieren und Anbieten von Informationen rückt für Unternehmen immer mehr in den Mittelpunkt, wobei die Menge, Hetereogenität und Vielfältigkeit von Information ein problematischer Aspekt bei deren Integration bleibt. Semantische Technologien eröffnen Unternehmen neue Möglichkeiten für das Verarbeiten: Eine Repräsentation mit Hilfe...

The amount of information that companies have to produce, acquire, maintain, propagate, and use has increased dramatically over the last decades. Nowadays, companies seek more capable approaches for gaining, managing, and utilizing knowledge, and the Semantic Web offers promising solutions. While the global Semantic Web still remains an unfulfilled...

Event-driven systems are highly depending on the quality of detection and processing of events. Many of complex real-world events cannot be processed by the existing event processing systems because they are too complex to be understood and processed by the systems. Complex events can be inferred from raw primitive events based on their incoming se...

Defined as a problem-relevant, explicit and formal specification of a shared conceptualization, ontologies became a new hype in the context of the Semantic Web. Being a shared knowledge its potential for information integration in the large World Wide Web is promising. But either the reuse of existing ontologies or the matching of different ontolog...

Abstract In this report, we introduce our initial vision of the Corporate Semantic Web as the next step in the broad,eld of Semantic Web research. We identify re- quirements of the corporate environment and gaps between current approaches to tackle problems facing ontology engineering, semantic collaboration, and se- mantic search. Each of these pi...

As an innovative approach for developing and maintaining continuously evolving ontologies in corporate context the Corporate Ontology Lifecycle Method-ology aims at providing an intuitive understanding of rising costs per iteration. In this regard having a close look at ontology partitioning techniques as well as module extraction approaches is ver...

Corporate Semantic Web aims at bringing semantic technologies to enter-prises for gaining, managing, and utilizing knowledge as one of the critical resources for their success in a quickly changing and highly competitive world. It provides solutions in three main application areas for semantic technologies, namely semantic engineering, semantic sea...

Ontologie als grundlegende Technologie des Semantic Webs gewinnen zunehmend an Bedeutung. Im Unternehmenskontext ist eine wirtschaftliche Ontologieentwicklung und -wartung essentiell. Dabei spielt die Modularisierung von Ontologien sowohl für die Wiederverwendbarkeit als auch für die einfache Wartbarkeit und Erweiterbarkeit eine große Rolle. Die Er...
