Sacodeyl Birmingham 2007

  1. 1. Spoken multimedia corpora for pedagogical purposes Sabine Braun (University of Surrey) Pascual Pérez-Paredes (Universidad de Murcia) Ylva Berglund (Oxford University) Birmingham Corpus Linguistics Conference 2007
  2. 2. Introduction <ul><li>The usefulness of corpora in language pedagogy is widely recognised. </li></ul><ul><li>But there is a need for pedagogically relevant corpora , reflected e.g. in initiatives to create 'ad-hoc' corpora in pedagogical contexts. </li></ul><ul><li>The creation of pedagogically relevant corpora raises challenges for corpus design. </li></ul><ul><li>Past and current initiatives have largely focussed on written corpora; spoken discourse is becoming more important in pedagogical contexts. </li></ul><ul><li>The creation of pedagogically relevant spoken corpora raises additional challenges for corpus design. </li></ul>
  3. 3. The challenges (1) <ul><li>CORPUS DESIGN Traditional reference corpora (content, size, data format, transcription, annotation, query) </li></ul><ul><li>CORPUS EXPLOITATION Data-Driven Learning (focus on non-linear reading: concordances and co-texts) </li></ul><ul><li>Corpora contain textual records of discourse; their interpretation requires (re-)contextualisation . </li></ul><ul><li>Learners may have difficulties analysing corpus data; they require pedagogical mediation . </li></ul><ul><li>Pedagogical corpus uses differ from linguistic description; this requires e.g. pedagogically motivated query options . </li></ul><ul><li>Corpora need to be integrated with curricula; this requires e.g. complementarity of content and effective delivery . </li></ul>Do not fully support pedagogical requirements.
  4. 4. The challenges (2) <ul><li>CORPUS DESIGN Traditionally: representation in written format </li></ul><ul><li>CORPUS EXPLOITATION Work with text-only data and e.g. conversational markup </li></ul><ul><li>Spoken discourse is more dependent on shared physical contexts. </li></ul><ul><li>It is adjusted to aural and online perception (e.g. chunking) </li></ul><ul><li>It is affected by limitations of processing capacity (false starts, repair). </li></ul><ul><li>It is marked by accents. </li></ul><ul><li>It is multimodal. </li></ul>Again, this does not fully support pedagogical requirements.
  5. 5. Requirements <ul><li>Format : multimedia to retain multimodal character of spoken language </li></ul><ul><li>Content : complementary with curriculum topics, more coherence than in traditional corpora </li></ul><ul><li>Pedagogically motivated transcription , annotation and alignment (transcript-video) </li></ul><ul><li>Combination of query methods : text-based exploration and application of corpus techniques </li></ul><ul><li>Pedagogical enrichment of corpora with complementary resources (e.g. exercises, explanations) </li></ul><ul><li>Effective delivery of corpora and additional resources to learners/teachers </li></ul>
  6. 6. Corpus creation (1) <ul><li>ELISA </li></ul><ul><li>Professional English </li></ul><ul><li>Accounts of professional life </li></ul><ul><li>Different varieties </li></ul><ul><li>SACODEYL </li></ul><ul><li>7 European languages </li></ul><ul><li>Youth language corpora </li></ul><ul><li>Speakers 13-15 and 16-18 </li></ul><ul><li>Examples: ELISA and SACODEYL </li></ul><ul><li>Interview format </li></ul><ul><li>Video clips with transcript </li></ul><ul><li>Communicatively relevant topics, e.g. in SACODEYL topics outlined in the Common European Framework </li></ul><ul><li>Elicitation process: briefing informants and prompting them during the interview, ensuring naturally flowing discourse </li></ul>
  7. 7. Corpus creation (1) Example of topics in SACODEYL Conditional Modal verbs B2 can speculate about causes, consequences, hypothetical situations 16-18 <ul><li>On what grounds do you decide? </li></ul>Future B1 can explain/give reasons for my plans, intentions and actions 16-18 <ul><li>What are your plans for your career? </li></ul>Plans for the future Future Conditonal Modal verbs B1 can describe dreams, hopes and ambitions 13-15 <ul><li>What are your plans for the next holidays? </li></ul>Past tense A2 can describe past activities, personal experiences 13-15 16-18 <ul><li>Where did you spend your last holidays? </li></ul>Holidays Gramm. functions CEF Age Interview questions Topic
  8. 8. Corpus creation (2) Markup Pedagogic annotation XML files TEI-compliant corpora Transcription CONTINUUM RAW, ORTHOGRAPHIC TRANSCRIPTION – ANNOTATED CORPORA
  9. 9. Corpus creation (2) SACODEYL TRANSCRIPTOR SACODEYL ANNOTATOR Markup Pedagogic annotation XML files TEI-compliant corpora Transcription

  12. 18. Corpus query <ul><li>Query options will support text- and corpus-based exploration and include e.g. </li></ul><ul><ul><li>Easy access to entire interviews </li></ul></ul><ul><ul><li>A topic index supporting the analysis of similar sections across interviews (&quot;topic concordances&quot;) </li></ul></ul><ul><ul><li>Other indices based on the annotation categories </li></ul></ul><ul><ul><li>Ready-made data (e.g. frequency lists of each interview; selective concordances) </li></ul></ul><ul><ul><li>A concordancer for extended/advanced search; adapted to pedagogical requirements </li></ul></ul>
  13. 19. Corpus query
  14. 20. Pedagogical enrichment <ul><li>The corpora will be enriched with prototypical learning activities. </li></ul><ul><li>These will focus on one interview section or one interview as a whole or sections across interviews… </li></ul><ul><li>They will include e.g. </li></ul><ul><ul><li>linguistic and cultural explanations and exercises (form-focussed as well as communication-oriented), </li></ul></ul><ul><ul><li>(listening) comprehension and production tasks, </li></ul></ul><ul><ul><li>explorative tasks (concordance-based as well as interview-based). </li></ul></ul><ul><li>Use of authoring tool Telos Language Partner to create learning packages with ranges of activities. </li></ul>

  19. 25. Corpus delivery <ul><li>Effective delivery as a further prerequisite for integration into curriculum </li></ul><ul><li>In SACODEYL, use of Moodle learning platform, giving access to: </li></ul><ul><ul><li>Corpora (query interfaces) </li></ul></ul><ul><ul><li>Resources created in the project (different types of learning activities) </li></ul></ul><ul><ul><li>Resources created by future corpus users </li></ul></ul>
  20. 26.
