OWLÎĵµ±à¼­Æ÷¡ªSemanticWorks® 2009ÏÂÔØ[ÏÂÔØ] SemanticWorks® 2009 allows you to work with existing OWL documents or create new ones from scratch. Example OWL ontology files are shipped with the product, and the help file included with SemanticWorks contains an informative OWL tutorial to get you started learning OWL quickly and easily. SemanticWorks® 2009 separates the different components that make up an ontology onto five tabs: Classes, Properties, Instances, allDifferent, and Ontologies. The classes tab lists all the classes available in the ontology with a separate window that lists the instances and properties of the selected class. All the properties of the ontology are listed on the Properties tab, and a separate window below the tab lists the domain of the currently selected property. All instances are listed on the next tab, and the allDifferent tab lists the items in the ontology that are mutually distinct. Lastly, the Ontologies tab lists all resources that are ontologies, including ontologies that have been imported into the current file. The details entry helper window provides a compact and editable description of any item selected in the Main Window. In an ontology, the Details Window is especially useful for creating and editing instances of a class. ×¢ÒâÏÂÔØÊÔÓðæʱÐèÒªÊäÈëÓû§ÃûºÍÓÊÏ䣬½öÐèµã»÷ÏÂÔؽçÃæÓұߵÄmail the product£¬ÉêÇëµ½ÐòÁкţ¬¼´¿É¡£    Êղؠ  ·ÖÏí   ¶¥(0)
