Word sketch

Word sketch 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 Word sketch rather than just read about it. In short: A word sketch is a one-page, automatic, corpus-derived summary of a word’s grammatical and collocational behaviour. Word sketches were first introduced by the British corpus linguist Adam Kilgarriff and exploited within the Sketch Engine corpus management system.

Key takeaways

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

Reference excerpt

A word sketch is a one-page, automatic, corpus-derived summary of a word’s grammatical and collocational behaviour. Word sketches were first introduced by the British corpus linguist Adam Kilgarriff and exploited within the Sketch Engine corpus management system. They are an extension of the general collocation concept used in corpus linguistics in that they group collocations according to particular grammatical relations (e.g. subject, object, modifier etc.). The collocation candidates in a word sketch are sorted either by their frequency or using a lexicographic association score like Dice, T-score or MI-score. Since the introduction, word sketches have been used by lexicographers to develop modern corpus-based dictionaries by major publishing houses including Oxford English Dictionary, Macmillan English Dictionary and comprising dozens of languages including English, Chinese, Slovene, Japanese, Dutch, Romanian, Russian, Czech, Polish, Vietnamese, Turkish, Portuguese, Hindi, Spanish and others.

Formal account A word sketch triple is a triple consisting of headword, grammatical relation, collocation (e.g. man, modifier, young). Considering an underlying text corpus, a word sketch quintuple is a quintuple consisting of headword, grammatical relation, collocation, position of headword in the corpus, position of collocation in the corpus (e.g. man, modifier, young, 104, 103). A word sketch database is a set of such triples or quintuples, which may be generated either by querying a corpus using corpus query language or by parsing the corpus using a natural language parser.

Worked examples

Example 1 — a first encounter with Word sketch

Start with the simplest possible case. Write down what Word sketch 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 Word sketch 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 Word sketch 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 Word sketch

In research: Word sketch 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 Word sketch 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: Word sketch is common in secondary-school and first-year university syllabi. It links to neighbouring topics Corpus linguistics, so understanding it makes those chapters shorter.
In everyday life: Look for Word sketch 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 Word sketch in simple terms?

Why does Word sketch 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 Word sketch?

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.
