  1. 1. Studies in Semantic Modeling of Real-World Objects using Perceptual Anchoring

    Författare :Andreas Persson; Amy Loutfi; Alessandro Saffiotti; Severin Lemaignan; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Perceptual Anchoring; Semantic World Modeling; Sensor-Driven Acquisition of Data; Object Recognition; Object Classification; Symbol Grounding; Probabilistic Object Tracking;

    Sammanfattning : Autonomous agents, situated in real-world scenarios, need to maintain consonance between the perceived world (through sensory capabilities) and their internal representation of the world in the form of symbolic knowledge. An approach for modeling such representations of objects is through the concept of perceptual anchoring, which, by definition, handles the problem of creating and maintaining, in time and space, the correspondence between symbols and sensor data that refer to the same physical object in the external world.

  3. 2. Semantic description and communication of going around in a simulated world

    Författare :Nazeer T. Mohammed Saeed; Klaus-Dieter Kuhnert; Madjid Fathi; Germany Siegen Naturwissenschaftlichen-Technischen Fakultät der Universität Siegen Institut für Echtzeit Lernsysteme (EZLS); []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Robotics; Semantic Web; Human-robot communication; Robot-robot communication; Semantic environment description;

    Sammanfattning : In recent years, mobile robots have helped to link predictions, imaginations, and expectations to human life. The tsunami of research on mobile robots mirrors their importance in various fields, such as production, agriculture and medicine. LÄS MER

  4. 3. Robust execution of robot task-plans : a knowledge-based approach

    Författare :Abdelbaki Bouguerra; Lars Karlsson; Alessandro Saffiotti; Froduald Kabanza; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Autonomous mobile robots; plan execution and monitoring; semantic knowledge; cognitive robotics.; Computer science; Datavetenskap; Computer and Systems Science; Data- och systemvetenskap;

    Sammanfattning : Autonomous mobile robots are being developed with the aim of accomplishing complex tasks in different environments, including human habitats as well as less friendly places, such as distant planets and underwater regions. A major challenge faced by such robots is to make sure that their actions are executed correctly and reliably, despite the dynamics and the uncertainty inherent in their working space. LÄS MER

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

    Författare :Zlatan Dragisic; Patrick Lambrix; Fang Wei-Kleiner; Guilin Qi; Linköpings universitet; []
    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

  7. 5. Pre-deployment Description Logic-based Reasoning for Cloud Infrastructure Security

    Författare :Claudia Cauli; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Formal Methods; Automated Reasoning; Cloud; Security; Description Logic;

    Sammanfattning : Ensuring the security of a cloud application is exceptionally challenging. Not only is cloud infrastructure inherently complex, but also a precise definition of what is secure is hard to give. LÄS MER
