  1. Molecular Interactions. On the Ambiguity of Ordinary Statements in Biomedical Literature.Stefan Schulz & Ludger Jansen - 2009 - Applied Ontology (4):21-34.
    Statements about the behavior of biochemical entities (e.g., about the interaction between two proteins) abound in the literature on molecular biology and are increasingly becoming the targets of information extraction and text mining techniques. We show that an accurate analysis of the semantics of such statements reveals a number of ambiguities that have to be taken into account in the practice of biomedical ontology engineering: Such statements can not only be understood as event reporting statements, but also as ascriptions of (...)

  2. Adapting Clinical Ontologies in Real-World Environments.Holger Stenzhorn, Stefan Schulz, Martin Boeker & Barry Smith - 2008 - Journal of Universal Computer Science 14 (22):3767-3780.
    The desideratum of semantic interoperability has been intensively discussed in medical informatics circles in recent years. Originally, experts assumed that this issue could be sufficiently addressed by insisting simply on the application of shared clinical terminologies or clinical information models. However, the use of the term ‘ontology’ has been steadily increasing more recently. We discuss criteria for distinguishing clinical ontologies from clinical terminologies and information models. Then, we briefly present the role clinical ontologies play in two multicentric research projects. Finally, (...)

    Enhanced Cardiac Perception Is Associated With Increased Susceptibility to Framing Effects.Stefan Sütterlin, Stefan M. Schulz, Theresa Stumpf, Paul Pauli & Claus Vögele - 2013 - Cognitive Science 37 (5):922-935.
    Previous studies suggest in line with dual process models that interoceptive skills affect controlled decisions via automatic or implicit processing. The “framing effect” is considered to capture implicit effects of task-irrelevant emotional stimuli on decision-making. We hypothesized that cardiac awareness, as a measure of interoceptive skills, is positively associated with susceptibility to the framing effect. Forty volunteers performed a risky-choice framing task in which the effect of loss versus gain frames on decisions based on identical information was assessed. The results (...)

    How to Distinguish Parthood From Location in Bioontologies.Stefan Schulz, Philipp Daumke, Barry Smith & Udo Hahn - 2005 - In Proceedings of the AMIA Symposium. American Medical Informatics Association. pp. 669-673.
    The pivotal role of the relation part-of in the description of living organisms is widely acknowledged. Organisms are open systems, which means that in contradistinction to mechanical artifacts they are characterized by a continuous flow and exchange of matter. A closer analysis of the spatial relations in biological organisms reveals that the decision as to whether a given particular is part-of a second particular or whether it is only contained-in the second particular is often controversial. We here propose a rule-based (...)

    As health systems around the world turn towards highly distributed, specialized and cooperative structures to increase quality and safety of care as well as efficiency and efficacy of delivery processes, there is a growing need for supporting communication and collaboration of all parties involved with advanced ICT solutions. The Electronic Health Record (EHR) provides the information platform which is maturing towards the eHealth core application. To meet the requirements for sustainable, semantically interoperable, and trustworthy EHR solutions, different standards and different (...)

    Anatomical Information Science.Barry Smith, Jose Mejino, Stefan Schulz, Anand Kumar & Cornelius Rosse - 2005 - In A. G. Cohn & D. M. Mark (eds.), Spatial Information Theory. Springer. pp. 149-164.
    The Foundational Model of Anatomy (FMA) is a map of the human body. Like maps of other sorts – including the map-like representations we find in familiar anatomical atlases – it is a representation of a certain portion of spatial reality as it exists at a certain (idealized) instant of time. But unlike other maps, the FMA comes in the form of a sophisticated ontology of its objectdomain, comprising some 1.5 million statements of anatomical relations among some 70,000 anatomical kinds.

    Using Cross-Lingual Information to Cope with Underspecification in Formal Ontologies.Werner Ceusters, Ignace Desimpel, Barry Smith & Stefan Schulz - 2003 - Studies in Health Technology and Informatics 95:391-396.
    Description logics and other formal devices are frequently used as means for preventing or detecting mistakes in ontologies. Some of these devices are also capable of inferring the existence of inter-concept relationships that have not been explicitly entered into an ontology. A prerequisite, however, is that this information can be derived from those formal definitions of concepts and relationships which are included within the ontology. In this paper, we present a novel algorithm that is able to suggest relationships among existing (...)

    Statements about the behavior of biological entities, e.g. about the interaction between two proteins, abound in the literature on molecular biology and are increasingly becoming the targets of information extraction and text mining techniques. We show that an accurate analysis of the semantics of such statements reveals a number of ambiguities that is necessary to take into account in the practice of biomedical ontology engineering. Several concurring formalizations are proposed. Emphasis is laid on the discussion of biological dispositions.

    Substance Concentrations as Conditions for the Realization of Dispositions.J. Hastings, L. Jansen, Stefan Schulz & C. Steinbeck - 2011 - In Ronald Cornet & Stefan Schulz (eds.), Semantic Applications in Life Sciences. Proceedings of the 4th International Workshop on Formal Biomedical Knowledge Representation, hosted by Bio-Ontologies 2010.
    Ontologies aim to represent what is general, by means of universal statements. In contrast, dispositional predications capture knowledge about what is likely to happen if a certain set of circumstances obtain, which is crucial in investigative research such as in drug discovery and systems biology, where entities which are constitutionally dissimilar can nevertheless have similar behavior in a biological context. While such dispositional properties are increasingly included in biomedical ontologies, the circumstances under which the dispositions are realized are seldom explicitly (...)

    Propomos uma tipologia dos artefatos de representação para as áreas de saúde e ciências biológicas, e a associação dessa tipologia com diferentes tipos de ontologia formal e lógica, chegando a conclusões quanto aos pontos fortes e limitações da ontologia de diferentes tipos de recursos lógicos, enquanto mantemos o foco na lógica descritiva. Consideramos quatro tipos de representação de área: (i) representação léxico-semântica, (ii) representação de tipos de entidades, (iii) representação de conhecimento prévio, e (iv) representação de indivíduos. Defendemos uma clara (...)
