澳洲essay代寫案例:Designing Good 澳洲代寫 with an

Designing Good 澳洲essay代寫<标题> with an OWL Protégé

Your task is to understand the Good 澳洲essay代寫 e-commerce ontology and its applications, building a small ontology yourself using the Protégé ontology editor.

<标题> You will create an ontology and a written report. The report must include some explanations and illustrative examples to show what you have done and how.

The Good 澳洲essay代寫 Ontology itself and some documentation and use cases for it are described here http://purl.org/good澳洲essay代寫. You might find the video on the home page to be helpful for some of these questions about the applications of ontologies in e-commerce. Note that not all the linked documentation pages are complete—but this assignment only relies on information that is present on that website. The Specification (on the menu bar at the top) provides access to the ontology itself and to documentation. From the Specification page, choose the “RDF/XML” link from “Latest version” to download the ontology. You will also see documentation on all the terms and a diagrammatic representation of the ontology (see UML Class Diagram in the Table of Contents on the left). Note that unlabelled links in the diagram mean owl:subClassOf.

1. Using the Protégé ontology editor, create your own new ontology. First, give your ontology a name and a file location redStuff.rdf, saving it in RDF/XML format. Then, import (owl:imports) the good 澳洲essay代寫 ontology into yours.

<标题> 2. Think of a product you would like to sell on the web. Imagine you sell only predefined packages of various quantities of components. Everything you sell is red in colour. You will only need three basic components. But you offer to sell them in four or more different combination packages. You will need to set the price of each package and to specify a payment method. You should also specify some other aspects of your packages. To do this you will need at least to create individual instances of the classes (and relating properties) gr:BusinessEntity, gr:Offering, gr:TypeandQuantityNode, gr:SomeItems, and gr:PriceSpecification. Be sure to instantiate some of the relevant Datatype properties too. For example, give the gr:SomeItems a value for gr:name and gr:color.

In your written report: explain your product and the ways you sell it, as you have modelled it in good 澳洲essay代寫.

Hints. You might find it helpful to remember partial information is quite OK in OWL. Even though the domain of gr:hasNAICS is a gr:BusinessEntity, for example, you can assert an individual of type gr:BusinessEntity without saying anything about the gr:hasNAICS property value.

<标题> 3. Use a reasoner to check your ontology. Ensure that there are no classes that are equivalent to owl:Nothing and that there are no inconsistent individuals. Explain how you did this.

4. Create a class called “SimilarProducts” that is a subclass of gr:ProductOrService. Make it fully defined (owl: equivalentClass) as exactly those that are gr: isSimilarTo at least one gr:ProductOrService. You may like to check that gr:isSimilarTo is not Reflexive. Using a reasoner and some example instances, show how inference can be used to classify some individual instances of gr:ProductOrService as SimilarProducts. Explain what you have done and why it works, with examples.

<标题> 5. Create a new individual gr:BusinessEntity and assert that it gr:hasBrand Friday (use the individual Friday that already occurs in good 澳洲essay代寫, do not use a literal or a new individual of your own). Use a reasoner to check your ontology and explain what is happening here. Then remove the ontology constructs you have created for this question.

<标题> 6. Discuss how good 澳洲essay代寫 is being used in e-commerce in practice. Describe at least three advantages to a vendor offered by using good 澳洲essay代寫 on a website.

 

Submit

1. Your ontology as an RDF/XML file named redStuff.rdf.

<标题> 2. Your written report named redReport.pdf or redReport.html (PDF is preferred, HTML is acceptable: must display well in Firefox).
