Today’s session • An introduction to some features of tools • Demo of different (kinds of) tools • Hands-on practice with one tool AIM: Help you know what to look for in a tool for your work (and what options there are)
There are different TYPES OF TOOLS
Different kinds of tools • Online / offline • For one particular corpus / for any corpusor text • Use straight away / need to prepare corpus • 'Free' / licence conditions and costs
Different kinds of tools • Online / offline • For one particular corpus / for any corpus or text • Use straight away / need to prepare corpus • 'Free' / licence conditions and costs
Tools may • have different functions: concordance, wordlist, statistics, collocation, keywords… • handle annotation: interpret tags, ignore tags, treat tags as text • take different text formats: .txt, .xml, .html
Different tools have different functions. TYPICAL FUNCTIONS
Concordance • Search word + context • Can be displayed as KWIC • Can usually be sorted • Used to see patterns of use
Wordlist • List all words in the corpus • alphabetically • by frequency • Used as starting point for further functions • keywords • lexical density/readability calculations
Collocations • Co-occurrence patterns • borrow money • borrow books • borrow a car • May I borrow • (more in Session 3)
Collocates: adjectives immediately preceding BUSINESS Corpus of Contemporary American English http://www.americancorpus.org/
Visualization • Graphs • Word clouds • Distribution displays • Etc.
‘borrow’Compare your intuition to what you find in the corpus • What is borrowed and by whom? • What words do you expect to find together with borrow? • Can these words be grouped in some way, for example based on their word class, function, or meaning? • Where would you expect these words (e.g. before or after borrow? Immediately adjacent or not?) • Who do you think uses the work borrow? In what context or type of language would you find borrow? • Are there any words that are NOT used with borrow?
AntConc Download AntConc for free from: http://www.antlab.sci.waseda.ac.jp/antconc_index.html (or just search for Antconc) Use your own texts and corpora. Find some examples at: http://www.ota.ox.ac.uk/

Next week (Session 3)Collocation Corpus linguists claim to have identified an important principle is responsible for the creation of much of the meaning of texts – collocation (co-occurrences). What is it, and are the claims true? Optional reading: * Xiao, Richard, and Tony McEnery (2006).
