For programming project part 2, name the class names in your OWL ontology exactly the same as the attribute names in your result table (i.e. exactly the same as the object-set names in your OSM ontology). In the annotated Web page, include both the URI of the target class and the path from the target class to the root class of your OWL ontology. For instance, in the sample annotated Web page, when we annotate an instance of "Year", we write the annotation "carads.owl#Year(Year->CarAds)", where "carads.owl#Year" is the URI of class Year inside the ontology file, and (Year->CarAds) is the path from class "Year" to the root class "CarAds".
In my presentation about ontology languages there is a slide showing the links of two online OWL ontology validators. Use one of them to validate your OWL ontology.14 May 2004
Please read the example annotated Web page and example OWL ontology for the car advertisement domain. We will have a detailed discussion about the project Part 2 in next Monday's class.

Please pick a domain of interest for your programming project. Remember to find at least EIGHT different web pages for your selected domain. After you have selected the domain, write down the attributes that you want to extract. The number of attributes should be no less than 7.
