The coloured pens method 1political association 4 person in an agreement/dispute 2 social event 5 to be party to something... 3 group of people Kilgarriff, Lexical Computing
Age 2: limitations as corpora get bigger: too much data • 50 lines for a word: read all • 500 lines: could read all, takes a long time • 5000 lines: impossible Kilgarriff, Lexical Computing
Why do corpora keep getting bigger? (anyone?) • Improvements in technology • Price of storage is going down • Speed of access is going up • Representativeness • Small corpus many examples of common words, maybe • But not enough examples of unusual words
Lexical distribution • What’s the most common word in English? • What % does it make up of a whole corpus? • The 100 most common words make up __% of all the words in a corpus? • The 7500 most common words make up __% • Answers: • The, 5%, 45% and 90% • So: • you need massive corpora, if you want to really represent rare words properly
Limitation of KWIC analysis • As corpora get bigger: too much data • 50 lines for a word: read all • 500 lines: could read all, takes a long time • 5000 lines: no • Instead, look at a Word Sketch from Sketch Engine • a statistical summary of word usage • shows most common collocates
Functions of SkE • KWIC concordance • Sorting, filtering etc • Word sketch • Automatic thesaurus • Sketch difference • discriminate near-synonyms
Lexical approach to language learning • Lewis (1993) and Schmitt (2000) say • the vocab is stored in the brain in collocations • Bacon is stored near eggs • 蛋 is stored near 炒飯 • scotch is stored with whisky • Saying strong car or powerful tea or broken house seems very “foreign”
