  • ISM – Image Content Annotation Based on Visual Features
    Eighth IEEE International Symposium on Multimedia (ISM'06), 2006
    Co-Authors: Lei Ye, Philip Ogunbona, Jianqiang Wang

    Abstract:

    Automatic image content annotation techniques attempt to explore structural visual features of images that describe image content and associate them with image semantics. In this paper, two types of Concept spaces, Atomic Concept and collective Concept spaces, are defined and the annotation problems in those spaces are formulated as feature classification and Bayesian inference, respectively. A scheme of image content annotation in this framework is presented and evaluated as an application of photo categorisation using MPEG-7 VCE2 dataset and its ground truth. The experimental results show a promising performance.

  • DEXA Workshops – Semantic matchmaking in geo service chains: reasoning with a location ontology
    , 2004
    Co-Authors: R. Lemmens, H. Arenas

    Abstract:

    The growing demand for the discovery of geo Web services as parts of service chains necessitates semantic matchmaking between service descriptions. We propose a method for describing and matching services based on a geo location ontology and we demonstrate its power and its limitations with a simple user scenario. In a test environment using protege and the racer ontology reasoner we show some powerful constructs of Description Logics that allow us to distinguish different types of matches. We underline the importance of matching Atomic Concept conditions versus aggregated conditions. The use of OWL and OWL enabled tools prove to facilitate a powerful matchmaking environment.
