GoodRelations

GoodRelations is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand GoodRelations rather than just read about it. In short: GoodRelations is a Web Ontology Language-compliant ontology for Semantic Web online data, dealing with business-related goods and services. It handles the individual relationships between a buyer, a seller and the products and services offered.

Key takeaways

GoodRelations belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect GoodRelations to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of GoodRelations from memory before moving on to harder problems.

Reference excerpt

GoodRelations is a Web Ontology Language-compliant ontology for Semantic Web online data, dealing with business-related goods and services. It handles the individual relationships between a buyer, a seller and the products and services offered. In November 2012, it was integrated into the Schema.org ontology.

Usage GoodRelations became popular owing to its success in improving search engine results. By 2009, the ontology's Product concept was being used to describe over a million products and their prices. By 2013, GoodRelations had been adopted by the search engines Yahoo!, Google, and Bing. An analysis of online e-commerce data providers at that time found it to be the most prevalent ontology in use. As of mid-2015, GoodRelations had become the de facto ontology for e-commerce, and was in widespread use, having been adopted by retailers such as Best Buy. GoodRelations is additionally used in academic studies of the Semantic Web, as a core ontology.

Example A shop, restaurant, or store, and its opening hours, may be specified using GoodRelations as in this example, which also uses vCard and FOAF:

Worked examples

Example 1 — a first encounter with GoodRelations

Start with the simplest possible case. Write down what GoodRelations claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to GoodRelations before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about GoodRelations ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of GoodRelations

In research: GoodRelations appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses GoodRelations in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: GoodRelations is common in secondary-school and first-year university syllabi. It links to neighbouring topics Semantic Web, so understanding it makes those chapters shorter.
In everyday life: Look for GoodRelations outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is GoodRelations in simple terms?

Why does GoodRelations matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study GoodRelations?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
