HFE SERC 2006 Finding research on human factors Type “human factors” in the search engine Your prof. assigns you to do a survey paper on HFE. What do you do?

HFE SERC 2006 The domain of scholarly information But scholarly information has structure. We should leverage it. Producers publish information in a way to be digested easily – Identifiable sections, strong discourse structure – Reference and citations that form a citation network Consumers have ordinary tasks that they need to do with the literature – Literature survey – Subject expert identification – Technique / methodology to solve problem – Find equivalent / abstract version of specific problem

HFE SERC 2006 Research Objectives Have existing system – CiteSeer (700K PDF files covering an approximate 30% of computer science literature) Have some advanced services implemented (query expansion, spelling correction, keyphrase extraction, presentation synchronization and citation typing) Q: How to best integrate? Find suitable methods to integrate advanced scholarly digital library services with existing system 1. Map advanced services into work packages 2. Uncover new requirements that need new services to supported

HFE SERC 2006 Scope Broadly: user interface design w.r.t. information seeking Narrowing it down: Limit to computer science Limit to postgraduate students as user base Be implementation-aware, but generalize results for for research agenda Limit to dataset where full text of paper and presentation is available

HFE SERC 2006 Challenges Project requires acute awareness of: Different levels of expertise in user base – need to be task-aware Legacy user interface effects The evolution of information need over a project Privacy issues with annotations, session data Dynamic HTML capabilities Constraints of accessibility given by alternate resources

HFE SERC 2006 Applications Will be applied to our local version of CiteSeer Intent to make Singapore a key stop for CS students doing literature information seeking Further links between PI and NUS Libraries on porting such UI research to library catalog design
