I have to implement Association, Generalization, Composition and Agregation. Generalization is easy. Just need to create a sub-class or a super-class. Association, actualy I'm implementing using ObjectProperty tag. But I can't understand the difference between Domain and Range. For example: How to represent a relationship without direction? |-------| |------| | A |---------------------| B | |-------| |------| Who is my domain? Who is my Range? Thanks!!

It seems a simple problem at first, but quickly gets more difficult if you want to do more than one of: - make it "safe" for automated transformation, - capture as much of the "semantics" of the UML as possible, - make the results readable, and/or - support the full range of features of UML Class diagrams. My advice is to keep it simple. Assuming you are interested in UML 1.x models then: - Treat Aggregation (white diamond) as an Association. - Convert Associations with two-way navigation (no arrows on the ends) to TWO properties and make one an owl:inverseOf the other. - Convert Associations with one-way navigation to a single rdfs:Property. The navigation arrow points at the range of that property. - Convert Multiplicities on Association Ends to Property Restrictions for the class that is the domain of the corresponding property. - Convert Composition (black diamond) relationships to some particular rdfs:Property type that you define, such as hasPart. Be careful about what you specify for this property as this construct is much abused by UML modelers. There are also many problems that you can get into on the OWL side by mixing some of: cardinality constraints, inverseOf relations, subPropertyOf relations, and transitive properties. The OWL issues are discussed in: "Simple part-whole relations in OWL Ontologies" [1]. Since name scoping is different in UML and RDF/OWL, you will probably have to do something to keep the names unique on the OWL side (such as name mangling or creating many name spaces) or merge different elements of the UML model into more general concepts in the RDF/OWL model. (Note that you didn't mention Attributes so I didn't address them.) -Evan [1] http://www.w3.org/2001/sw/BestPractices/OEP/SimplePartWhole/index.html Evan K.

In order to assist multimedia processing algorithms and applications, researchers are proposing ways to enrich multimedia algorithms with knowledge representational formalisms. In this way the multimedia processing techniques could take advantage of formal representation and automated reasoning methods. On the other hand multimedia processing algorithms are usually facing a huge amount of uncertain and imprecise knowledge. Hence knowledge representational formalisms must be equipped with mechanisms that are able to cope with such type of knowledge. The last couple of years a quite impressive number of uncertainty handling formalism have been developed, like fuzzy and probabilistic Description Logics, fuzzy, possibilistic and probabilistic Logic Programming languages etc. Such logical formalisms combine expressive power and decidable reasoning techniques. The use of such formalisms in multimedia applications would greatly benefit these applications and will provide new research results. TOPICS Multimedia Content Representation and Reasoning. Image and Video Analysis with Uncertainty Reasoning. Segmentation. Recognition. Multimedia Information retrieval. Scene Interpretation. Automatic Annotation. Classification and indexing of multimedia information objects. IMPORTANT DATES Full Paper Submission: September 10, 2006 Acceptance Notification: October 1, 2006 Camera-Ready Papers due: November 2, 2006 Conference: December 6, 2006 SUBMISSION Each submission will be evaluated for acceptability by at leasttwo members of the Program Committee. Decisions about acceptance will be based on relevance to the above topic list, originality, potential significance, topicality and clarity. Since all accepted papers will be presented at the workshop, we require that at least one of the submitting authors must be a registered participant at the SAMT 2006 Conference, and committed to attend the MAUR Workshop. MAUR 2006 welcomes the submission of two kind of papers: short position paper (2 pages maximum in Springer LNCS format), giving a brief description of an on-going implementation, algorithm or system. full papers (8 pages maximum in Springer LNCS format), good original research and application papers of the topics of the workshop. Papers must be submitted directly by email in PDF format to gstoil at image.ece.ntua.gr prior to the paper submission deadline. Paper submissions must be formatted in the style of the Springer Publications format for Lecture Notes in Computer Science (LNCS). For complete details, see Information for LNCS Authors. All papers selected by the program committee will be published by provided by the SAMT. All papers accepted will be presented during the workshop. This would include 20 minutes presentation (15 minutes presentation + 5 minutes discussion) for full papers, while authors of accepted position papers will have a 5-minute slot to share their ideas.
