  3. Quick summary from LAST WEEK’S SESSION

  4. Need to know • What is in your corpus • How to extract information • How to use information

  5. There are different TYPES OF TOOLS

  6. Different kinds of tools • Online / offline • For one particular corpus / for any corpus • Use straight away / prepare corpus • 'Free' / licence conditions and costs

  7. Tools may • take different text formats: .txt, .xml, .html • have different functions: concordance, wordlist, statistics, collocation, … • handle annotation • interpret tags, ignore tags, treat tags as text

  8. Different tools have different functions. TYPICAL FUNCTIONS

  9. Concordance • Search word + context • Can be displayed as KWIC • Can usually be sorted • Used to see patterns of use

Chambers-Rostand Corpus of Journalistic French – made with AntConc Word List (frequency and alphabetical) 1 110721 de 2 58740 la 3 44832 l 4 43136 le 5 41836 à 6 37974 les 7 36106 et 8 34903 d 9 33714 des 10 27968 en 11 25300 du 12 23830 un 13 21088 est 14 20357 a 15 20146 une 29 4 abaissement 30 22 abaisser 31 6 abaissée 32 2 ABANDON 33 56 abandon 34 4 abandonnait 35 12 abandonnant 36 20 abandonne 37 8 abandonnent 38 40 abandonner 39 2 abandonnerons 40 2 abandonneront 41 2 ABANDONNÉ 42 42 abandonné 43 8 abandonnée

  13. Questions to consider when choosing corpus tool • What functions does it have? • What languages can it handle? • What text format? • What platform (PC, Mac, Unix) • How does it deal with tags and annotation? • Is there any user support? • What will it cost (now and later)? • What are the alternatives?

  14. DEMO

  15. What’s the question? Foreign learners of French often misuse phrases involving the word 'question'. English speakers often make errors, for example saying 'demander une question' or 'il y a question de'. How is 'question' more typically used by native speakers?

  19. 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).
