Presentation at International Association of School Librarianship Research Forum, describing a joint proof of concept project undertaken by researchers from the Flinders University Artificial Intelligence Laboratory in partnership with information managers from the Education Network Australia (edna) team at Education Services Australia to address the question of whether artificial intelligence techniques could be employed to help with creation and consistency of learning resource metadata and improve the efficiency of digital collection workflows?
6. Educational value Curriculum relevance Intended user Educational level Educational quality How can I use this for learning?
7.
8. Research question Can artificial intelligence tools and techniques assist with discovering, evaluating and tagging digital learning resources?
9. Research partners Flinders University Artificial Intelligence and Language Lab V.A.L.I.A.N.T. Education Network Australia (edna)
10. Proof of concept 3 people $30,000 3 months 3 show and tells blog for peer review
11. Research team Dr Richard Leibbrandt Dr Dongqiang Yang Darius Pfitzner Prof David Powers Pru Mitchell Sarah Hayman Helen Eddy
12. Technical concepts artificial intelligence text classification (TC) semantic annotation Text Frequency/Inverse Document Frequency (TFIDF) semantic web taxonomy and folksonomy
13. DSpace metadata tool Text Extraction tool Subject Keywords Resource edna Categories html edna-userlevel edna-audience Educational use elements
14. Key phrase extraction a (the full text document) ? b (keywords, audience, userlevel) Which terms in the text prompt this decision?

17. Findings labour-intensive challenge subject classification easier than userlevel audience and user level indicated by meaning, vocabulary, choice of words, style, font size, graphic elements, layout ‘reading’ web pages is a complex literacy
18. Semantic network Automated subject analysis Can system predict edna category? Tools WordNetWikipediaDbpedia
27. Benefits Efficiency of cataloguing through classification suggestions Improved user experience through more relevant and consistent search results Improved integration of user contributed resources if tags are mapped to taxonomy
28. Conclusions Artificial intelligence systems showed some success in subject categorisation of text-based digital learning resources Key phase extraction to support subject categorisation was more successful than of audience and user-level categorisation
29. Summary Automated classification based on artificial intelligence may be useful as a means of supplementing and assisting human classification, but is not at this stage a replacement for human classification
