The goal To describe resources for education so learners and educators can find the right resource at the right time
every reader his/her book Ranganathan 1931, 5 principles of library science
Educational value Curriculum relevance Intended user Educational level Educational quality How can I use this for learning?
Research question Can artificial intelligence tools and techniques assist with discovering, evaluating and tagging digital learning resources?
Research partners Flinders University Artificial Intelligence and Language Lab V.A.L.I.A.N.T. Education Network Australia (edna)
Proof of concept 3 people $30,000 3 months  3 show and tells blog for peer review
Research team Dr Richard Leibbrandt Dr Dongqiang Yang Darius Pfitzner Prof David Powers Pru Mitchell Sarah Hayman Helen Eddy
Technical concepts artificial intelligence text classification (TC) semantic annotation Text Frequency/Inverse Document Frequency (TFIDF) semantic web taxonomy and folksonomy
DSpace metadata tool Text Extraction tool Subject Keywords Resource edna Categories html edna-userlevel edna-audience Educational use elements
Key phrase extraction a (the full text  document) ?  b (keywords, audience, userlevel) Which terms in the text prompt this decision?
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
Semantic network Automated subject analysis Can system predict edna category? Tools WordNetWikipediaDbpedia
Findings
User terms to thesaurus Schools Online Thesaurus scot.curriculum.edu.au Can system predict ScOT terms from teacher keywords?
User metadata the only group that can categorize everything is everybody Clay Shirky, 2005Ontology is overrated
Mapping teacher tags Proper nouns & brands .NET, iPod, excel Semantic ambiguity notes  -> Pitch (Music) Stemming practice exams  ->  Practical Examinations
Findings % ScOT terms predicted from keywords
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
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
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
Future  ScOT development Achievement Standards Network Machine Readable Curricula Multilingual thesauri OER ‘travelling well’ globally
