    Experience management for electronic design reuse through quality-oriented IP selection
    (1st German workshop on experience management: sharing experiences about the sharing of experience, 2002) Bergmann, Ralph; Maximini, Rainer; Schaaf, Martin
    The growing complexity of today's electronic designs requires reusing existing design components, called Intellectual Properties (IPs). Experience management approaches can be used to support design reuse, particularly the process of selecting reusable IPs. For the IP selection, quality criteria concerning the IP code and the documentation must be considered in addition to functional requirements for the IP. We analyse IP quality criteria in detail and show different concepts for their integration into the retrieval process.

    Inverse workflows for supporting agile business process management
    (6th Conference on Professional Knowledge Management – From Knowledge to Action, 2011) Sauer, Thomas; Minor, Mirjam; Bergmann, Ralph
    Agile processes allow organizations to flexibly react on new and unforeseen situations. However, modifications must adhere to the standards and quality requirements given by an organization. In this paper, the concept of inverse workflows is presented to support organizations in meeting this goal. Inverse workflows provide a means to explicitly express unwanted procedures and work situations. In conjunction with an automated system to detect inverse workflow enactment, organizations can prevent undesired developments while they are emerging. This effectively allows controlling overall process quality while modeling or adapting business process to stakeholder demand.

    On the relations between structural case-based reasoning and ontology-based knowledge management
    (WM 2003: Professionelles Wissesmanagement – Erfahrungen und Visionen, Beiträge der 2. Konferenz Professionelles Wissensmanagement, 2003) Bergmann, Ralph; Schaaf, Martin
    This paper addresses the relations between ontology-based knowledge management implemented by logic-oriented knowledge representation/retrieval approaches and knowledge management using case-based reasoning. We argue that knowledge management with CBR does not only very much resemble but indeed is a kind of ontology-based knowledge management since it is based on closely related ideas and a similar development methodology, although the reasoning paradigms are different. Therefore, we conclude by proposing to merge logic-oriented and casebased retrieval and also to extend the current view of the semantic web architecture respectively.

    The ReCAP Project
    (Datenbank-Spektrum: Vol. 20, No. 2, 2020) Bergmann, Ralph; Biertz, Manuel; Dumani, Lorik; Lenz, Mirko; Ludwig, Anna-Katharina; Neumann, Patrick J.; Ollinger, Stefan; Sahitaj, Premtim; Schenkel, Ralf; Witry, Alex
    Argumentation Machines search for arguments in natural language from information sources on the Web and reason with them on the knowledge level to actively support the deliberation and synthesis of arguments for a particular user query. The recap project is part of the Priority Program ratio and aims at novel contributions to and confluence of methods from information retrieval, knowledge representation, as well as case-based reasoning for the development of future argumentation machines. In this paper we summarise recent research results from the project. In particular, a new German corpus of 100 semantically annotated argument graphs from the domain of education politics has been created and is made available to the argumentation research community. Further, we discuss a comprehensive investigation in finding arguments and argument graphs. We introduce a probabilistic ranking framework for argument retrieval, i.e. for finding good premises for a designated claim. For finding argument graphs, we developed methods for case-based argument retrieval considering the graph structure of an argument together with textual and ontology-based similarity measures applied to claims, premises, and argument schemes.

    Towards Scientific Workflows and Computer Simulation as a Method in Digital Humanities
    (INF-DH-2018, 2018) Lebherz, Daniel S.; Zeyen, Christian; Hess, Jan; Bergmann, Ralph; Timm, Ingo J.; Burch, Thomas; Hildenbrandt, Vera; Moulin, Claudine
    This paper presents ongoing work on investigating text mining by scientific workflows and hypotheses testing by computer simulation as new digital methods in the digital humanities and particularly in the literary studies. In the course of the eXplore! project, the methods are developed for analyzing autobiographic texts and particularly for investigating the diaries of Klaus Mann, a famous German writer, with regards to the influences on the writer’s literary productivity. Text mining is used to build up a data basis for an agent-based model that can be used in simulation studies to answer what-if-questions about a writer’s creative writing processes. A further focus is put on the reusability of these methods to facilitate an application beyond the project’s pilot study. For this purpose, we model and apply scientific workflows, populate a repository of proven workflows, and investigate an approach to reuse assistance by case-based reasoning.
