  1. Extracting metadata to enable simple repository deposit Dawn Wood & Janet Finlay Leeds Metropolitan University d.a.wood@leedsmet.ac.uk j.finlay@leedsmet.ac.uk http://streamlinenews.wordpress.com/

  2. First … What KEYWORDS would you use to for this image?

  3. Self-Deposit

  4. Workflows: Recorded Lecture Course/Module materials

  5. Workflows: Create Podcast

  6. Workflows: General LO creation

  7. Observations of metadata creation • When entering metadata for a learning object observations show that: • Phrases rather than single words are used • Repeated content is often used • Very few keywords are entered if any • The keywords used were either very specific or very generic, rarely a mixture of both • This creates a problem for searchers of information and limits the possibility of the learning object being found within a repository

  8. eCat Metadata templates Images from eCat training manual by Meg Soosay

  9. Wimba Create Images from WimbaCreate training manual by Jill Talyor

  10. Assumptions • Deposit of existing materials • Just add metadata • Documentation describes the learning object • More keywords are better • This is reliant on good search techniques • Not starting from a blank slate is easier • Generate a selection list • Author still feels in control

  11. Prototype: Start

  12. Prototype: Collections

  13. Prototype: Generating Keywords

  14. Example Results for Podcasts • For a Podcast on Accessibility produced by CETL ALiC • One of the authors used the following key words and phrases: • HCI • Accessibility • User centred design • Disability Remember that different users will find different aspects of your interface difficult. For exampleusers who are colour blind will not see colours as you intend and may not be able to distinguish between colours on the screen. You can test how your colours will look using an online simulator. Extract from script • accessibility • blind • colours • disability • example • information • interface • podcasts • potential • produced • reader • screen • test • text • user • accessible • users • Missing: • HCI • centred • design From 6 to 14 Key Users keywords Similar words removed Appropriate keywords Extracted words

  15. Workflow Evaluation

  16. Example • Author Suggested (SLP02): • MaxMSP, Audio, system, gamer, prototype, programming • Generated: (with stop and labelled) • object, patch, hyperlink, pagref, objects, bang, slider, max, number, using, random, sound, wav, pitch, tutorial, useful, time, input, message, ive • Final selection: • patch, objects, bang, max, sound, tutorial, maxmsp, max5 • Comment: • generated list helped them by: providing other suggestions I did not consider
