    Sammanfattning : This thesis explores the history of botany as a global collection-based science by tracing parallels between utopian traditions and botanical collecting, from their sixteenth-century beginnings to the present. A range of botanical collections, such as gardens, herbaria and classification systems, have played a central role in the struggle to discover a global or universal scientific order for the chaotic, diverse and locally shaped kingdom of plants.

  2. 2. Gated Bayesian Networks

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Marcus Bendtsen; Linköpings universitet.; Linköpings universitet.; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Bayesian networks have grown to become a dominant type of model within the domain of probabilistic graphical models. Not only do they empower users with a graphical means for describing the relationships among random variables, but they also allow for (potentially) fewer parameters to estimate, and enable more efficient inference.

  3. 3. Improving Software Security by Preventing Known Vulnerabilities

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :David Byers; Linköpings universitet.; Linköpings universitet.; [2013]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Software security; software process improvement;

    Sammanfattning : From originally being of little concern, security has become a crucial quality factor in modern software. The risk associated with software insecurity has increased dramatically with increased reliance on software and a growing number of threat agents. Nevertheless, developers still struggle with security. LÄS MER

  4. 4. Completing the Is-a Structure in Description Logics Ontologies

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Zlatan Dragisic; Linköpings universitet.; Linköpings universitet.; [2014]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Knowledge representation; ontology; ontology engineering; ontology debugging; description logics;

    Sammanfattning : The World Wide Web contains large amounts of data and in most cases this data is without any explicit structure. The lack of structure makes it difficult for automated agents to understand and use such data. LÄS MER

  5. 5. Completion of Ontologies and Ontology Networks

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Zlatan Dragisic; Linköpings universitet.; Linköpings universitet.; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; knowledge representation; ontology; ontology engineering; ontology debugging; ontology completion; ontology matching; description logics;

    Sammanfattning : The World Wide Web contains large amounts of data, and in most cases this data has no explicit structure. The lack of structure makes it difficult for automated agents to understand and use such data. A step towards a more structured World Wide Web is the Semantic Web, which aims at introducing semantics to data on the World Wide Web. LÄS MER
