Verknüpfung von Domänenwissen für ein Ontologie-basiertes IT-Management
(2018-05-14)
Mit der steigenden Komplexität von IT-Systemen wird auch die Verwaltung dieser Systeme komplexer. Den Fragestellungen, die sich durch diese Komplexität auf der Seite des Betriebs und der Überwachung von IT-Systemen stellen, wird durch integriertes und automatisiertes IT-Management begegnet, indem auch implizite Zusammenhänge zwischen Aspekten aus unterschiedlichen Sichten auf die Systeme berücksichtigt werden, sowie die weitgehende Eliminierung des manuellen Anteils bei Überwachung und Pflege der Systeme angestrebt ...

Regelbasiertes Reasoning auf massiv paralleler Hardware
(2015-10-15)
Eine wesentliche Funktionalität bei der Verwendung semantischer Technologien besteht in dem als Reasoning bezeichneten Prozess des Ableitens von impliziten Fakten aus einer explizit gegebenen Wissensbasis. Der Vorgang des Reasonings stellt vor dem Hintergrund der stetig wachsenden Menge an (semantischen) Informationen zunehmend eine Herausforderung in Bezug auf die notwendigen Ressourcen sowie der Ausführungsgeschwindigkeit dar. Um diesen Herausforderungen zu begegnen, adressiert die vorliegende Arbeit das Reasoning ...

On CD-systems of stateless deterministic R-automata with window size one
(2010-04-27)
We study cooperating distributed systems (CD-systems) of restarting automata that are very restricted: they are deterministic, they cannot rewrite, but only delete symbols, they restart immediately after performing a delete operation, they are stateless, and they have a read/write window of size 1 only, that is, these are stateless deterministic R(1)-automata. We study the expressive power of these systems by relating the class of languages that they accept by mode =1 computations to other well-studied language ...

CD-Systems of Stateless Deterministic R(1)-Automata Governed by an External Pushdown Store
(2011-01-06)
We study cooperating distributed systems (CD-systems) of stateless deterministic restarting automata with window size 1 that are governed by an external pushdown store. In this way we obtain an automata-theoretical characterization for the class of context-free trace languages.

Dynamic Injection of Scribble Features into Graphical Diagram Editors
(2015-05-20)
Almost everyone sketches. People use sketches day in and day out in many different and heterogeneous fields, to share their thoughts and clarify ambiguous interpretations, for example. The media used to sketch varies from analog tools like flipcharts to digital tools like smartboards. Whereas analog tools are usually affected by insufficient editing capabilities like cut/copy/paste, digital tools greatly support these scenarios. Digital tools can be grouped into informal and formal tools. Informal tools can be ...

On Globally Deterministic CD-Systems of Stateless R-Automata with Window Size One
(2011-03-30)
It is known that cooperating distributed systems (CD-systems) of stateless deterministic restarting automata with window size 1 accept a class of semi-linear languages that properly includes all rational trace languages. Although the component automata of such a CD-system are all deterministic, in general the CD-system itself is not, as in each of its computations, the initial component and the successor components are still chosen nondeterministically. Here we study CD-systems of stateless deterministic restarting ...

Towards Effective Natural Language Application Development
(2019)
There is a current trend that more and more computer programs analyze written or spoken natural language. For example, DVAs, IE systems, machine translation systems, and many other types of programs process natural language in order to solve specific use cases when interacting with humans via natural language. Amazon, Google, and Mycroft AI are just some of the companies that have produced DVAs capable of interacting with humans via voice. Such NLP applications use techniques from computer science and artificial ...
