Enhancing Language Learning Using Corpora Enhancing Language Learning Using Corpora Presentation Transcript

  • Using corpora to enhance language learning
    • Michael Barlow
  • Overview
    • wordlists
    • collocation lists
    • online concordancers
    • text analysis software
      • concordancers
      • ParaConc and Collocate
    • web-based exercises
    • data-driven learning materials
  • Wordlists – general and specialised
    • Wordlists have been around since before the invention of computers. General wordlists are used for curriculum development, textbook writing etc.
    • Also possible to produce a word list for a reading (or a possibly textbook)
  • Wordlists – general
    • Use existing wordlists such as West's General Service List and recent updates. Coxhead's Academic Wordlist. Kilgarriff's Wordlists based on the BNC.
  • Kilgarriff Page
  • Academic Word List
  • Academic Word List
  • Academic Word List
    • receptive list (based on morphological derivations)
    • the list excludes words found in non-academic texts (even if they occur in academic texts)
    • do we need subject or genre-specific wordlists? (Hyland)
  • Specialised Word List
    • Create a wordlist from a corpus (using concordancer or other utilities)
    • May need to create your own corpus – BootCaT ?? Silvia Bernadini
  • BootCaT
  • Vocab Profile
    • Tom Cobb's Vocab Profile
    • http://www.lextutor.ca/vp/eng/
  • Collocation lists
    • More difficult to find – use Collocation Dictionary??
    • Biber's work on lexical bundles
    • Use concordancer or utility to create ngram lists or locate collocations
    • Collocate – shown below
  • Concordancers
    • Online concordancer
  • Concordancers
  • Concordancers – americancorpus.org
  • Concordancers
    • Using a concordancer in the classroom
    • Corpus as a reference tool – query the corpus
      • can you say “the government are”
      • what is the difference between “for instance” and “for example”
      • Tim Johns – Data-driven Learning
        • (...caused economic development...)
  • Concordancers – text reconstruction exercises
  • Data-driven learning (deductive)
  • Data-driven learning (inductive)
  • Concordance data
    • DDL – highlighting/noticing/discovery learning
    • Highlight unexpected (for the learner) distinctions, uses etc.
    • Sequence data to build up knowledge
  • Parallel concordance data
    • Parallel concordance works on translation corpus
    • Students need to have same L1
  • Concordance data issues
    • KWIC format
    • Google effect
    • Data overload
    • Reauthenticating data
      • Sabine Braun – includes discourse perspective (Why did the speaker use that form?)
  • Parallel Corpora – DDL (CHUJO, Kiyomi)
  • Parallel Corpora – DDL (Chujo, Kiyomi)
  • Collocate
    • Software to extract collocations/terms
    • Word search + Span (2 words, 3 words etc.)
    • n-gram (bigram, trigram) list
    • Full extract -- collocations in a corpus
  •  
  • Search for analysis (Span = 2)
  • analysis - frequency
  • analysis - t-score
  • analysis - MI
  •  
  • Trigram search
  • Trigram -- by freq
  • Trigram -- alphabetical
  • Trigram -- by MI
  • Using batch mode –
  • Corpuslab.com
    • Familiar exercise authoring
    • Currently offline
    • Aims
      • avoid duplication of tasks -- identifying common collocations in Business English
      • Provide corpus/analysis resources
      • Bring corpus resources together with familiar exercise authoring

  • Corpora
    • Teacher/Author resource
    • Sample corpus -- CSPAE
    • Add other corpora such as MICASE
    • Create various options for searching that make use of corpus annotation
  • Simple searching
  •  
  •  
  • Aims
    • Create a language learning site
    • Encourage and facilitate use of corpus data
      • Matching exercise (up to 5 columns)
      • Provide access to word lists etc
      • Provide text analysis tools
  • Aims
    • Use traditional exercise types that teachers are familiar with
    • Give examples of creative uses of these standard exercises
