Survey results

Focus Groups Undergraduates PostgraduatesLike ratings and reviews from Citation as a recommendation other students „other people‟s experiences Wary of provenance valuable‟ Feed to module website Which module studied? Want synonyms How high a mark? Trust repository

Face to face interviews First impressions of recommendations (course-related) Asked to enter a search term. Results and recommendations explored. Asked about relevance Asked about preference for type of recommendation

Should we have a recommender system? “I think it would be a very good useful feature. It would be definitely very very useful” postgraduate Maths student“So it would be interesting to see what other people are looking at. Yes, I woulddefinitely use that because my limited knowledge of the library might mean thatother people were using slightly different ways of searching and getting differentresults.” undergraduate English Literature student I have just had a go, it was good with suggested papers that I had already found (which shows potential in my view) through Google.

Should we have a recommender system?“Im afraid my first reaction is to be a bit sceptical - it presumably doesnt tellyou if fellow students found the information/article useful or relevant to whatthey were looking for. I would hate to waste time following unproductivelinks laid down by others who might be failing students or think that any"lazy" students might develop poor practice by relying on what others hadlooked at. It sounds like a good idea but I think caution needs to beexercised. ”

Why they prefer course-related recommendations“I can’t be bothered with knowing what everybody else is interested in. Itake a really operational view you know, I’m on here, I want to get thereferences for this particular piece of work, and those are the people thatare most likely to be doing a similar thing that I can use.” H800 student“I suppose if I wasn’t so sure on an assignment it would perhaps be quiteuseful to see what other people were looking at to know if I was thinkingalong the right lines.” - Undergrad literature student

Suggestions for improvement“Maybe include a date. It would be interesting to know when a resourcewas last looked at” Postgraduate political philosophy student“If somebody used similar search but three years ago, is that going to carrythe same weight?” Postgraduate maths student Include course drop-down choice. “I would be looking at that and saying “which of my courses does it refer to?”

Recommendations usage Relationship 24% Search 40% Course 36%
