Web Services Modeling Language

Web Services Modeling Language 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 Web Services Modeling Language rather than just read about it. In short: WSML or Web Service Modeling Language is a formal language that provides a syntax and semantics for the Web Service Modeling Ontology (WSMO). In other words, the WSML provides means to formally describe the WSMO elements as Ontologies, Semantic Web services, Goals, and Mediators.

Key takeaways

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

Reference excerpt

WSML or Web Service Modeling Language is a formal language that provides a syntax and semantics for the Web Service Modeling Ontology (WSMO). In other words, the WSML provides means to formally describe the WSMO elements as Ontologies, Semantic Web services, Goals, and Mediators. The WSML is based on the logical formalisms as Description Logic, First-order Logic and Logic Programming.

Language variants of WSML WSML Core, defined as an intersection of the Description Logic and Horn Logic. Supports modeling classes, attributes, binary relations and instances. WSML-DL, extension of the WSML Core, fully captures the Description Logic S H I Q ( D ) {\displaystyle {\mathcal {SHIQ}}^{\mathcal {(D)}}} . WSML-Flight, extension of the WSML Core, provides features as meta-modeling, constraints and nonmonotonic negation. WSML-Rule, extension of the WSML-Flight, provides Logic Programming capabilities. WSML-Full, a unification of the WSML-DL and WSML-Rule.

Worked examples

Example 1 — a first encounter with Web Services Modeling Language

Start with the simplest possible case. Write down what Web Services Modeling Language 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 Web Services Modeling Language 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 Web Services Modeling Language 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 Web Services Modeling Language

In research: Web Services Modeling Language 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 Web Services Modeling Language 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: Web Services Modeling Language is common in secondary-school and first-year university syllabi. It links to neighbouring topics Semantic Web, Web services, so understanding it makes those chapters shorter.
In everyday life: Look for Web Services Modeling Language 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 Web Services Modeling Language in simple terms?

Why does Web Services Modeling Language 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 Web Services Modeling Language?

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.
