Recommendation and the Library


Published on

Services recommending books = BibTip, LibraryThing, University of Huddersfield borrowing recommendations, and articles – bX from Ex Libris, PubMed, Synthese (CISTI) now exist in the academic context. JISC in the UK is sponsoring a major project, MOSAIC: “Making Our Shared Activity Information Count.” This session will provide an overview of these recommendation systems, describe their different approaches to data mining, and discuss their role in improving information retrieval and user experience in a now nearly fully online scholarly information world.

  3. 3. Agenda• What will the future be like?• Recommender systems in general• “In the Wild”• New scholarly environments• Article recommenders• Interfaces• Contributions
  4. 4.
  5. 5. Recommender SystemsRecommender systems form a specific type of informationfiltering (IF) technique that attempts to present informationitems (movies, music, books, news, images, web pages, etc.)that are likely of interest to the user.
  6. 6. Library Book Recommendations
  7. 7.
  8. 8. Changes in Scholarly Communication• Greater focus on content users create and choices & preferences they make• User contribution increasingly important • Contributed explicitly by individuals• The Web is multi-directional
  9. 9. Changes in Scholarly Communication• Greater focus on content users create and choices & preferences they make• User contribution increasingly important • Contributed explicitly by individuals • Implicitly - usage data captured by the system (‘clickstreams’)• The Web is multi-directional
  10. 10. There is a need• Information overload calls for new tools that assist users in finding relevant information• Useful in the context of: • learning • exploring new fields of interest • inter-disciplinary work • specific information needs that are outside one’s field of expertise• Search is NOT the only way to find…
  11. 11. Scholarly Recommender ServiceNeed to: • Focus on scholarly materials – particularly articles (core unit of use) • Be based on structural analysis of usage and not just based on popularity
  12. 12. CiteULike Recommendations/embedded video removed from PPT – see
  13. 13. What is bX?• A service which taps into the power of the networked scholarly community to generate recommendations based on article usage• Based on data mining and structural analysis of aggregated usage data, across libraries and scholarly information environments • Massive repository of user data - growing• Derives from research done at Los Alamos National Laboratory by Johan Bollen and Herbert Van de Sompel
  14. 14. Interest in usage-based measures• COUNTER –• SUSHI -• JISC MOSAIC –• Metrics for scholarly evaluation: • UKSG Usage Factors project - • Project MESUR -
  15. 15. Implicit user contribution• Circulation data• Clickstreams, recording a search process• Actions • Item viewed • Item downloaded • Item sent • Item bookmarked • Item printed • Item stored
  16. 16. Potential uses of implicit contribution• Collection development• Evaluation• Trend analysis• Relevance ranking• Recommendations

  22. 22. Link resolver usage logs • A good basis: • Represent users’ information-seeking paths in a standardized way • Are across information providers • Are across institutions • There are a lot of them
  23. 23. Link resolver usage paths E-journal publisher site E-journal E-Book publisher OpenURL publisher site siteGoogle OpenURL Link OpenURL LibraryScholar Resolver interface OpenURL A&I Document databases Delivery Citation databases
  24. 24. Built on OpenURL• Usage data –OpenURL context objects-- is harvested from link resolver logs through OAI-PMH• Build a (very large) aggregate of usage data• Mine the aggregate to derive scholarly recommender services: a structure describing relationships between scholarly materials is created• bX receives OpenURL requests• A list of recommended materials is generated per request • open interface - accessible via API • viewable via SFX menu, other discovery interfaces

  27. 27. More about the interaction with bX• Request to bX is sent through an API• Results are returned as • XML (default) • Text • ATOM • RSS

  29. 29. Benefits of bX Contribution • Ongoing analysis of SFX usage data created by library users • Continual improvement of recommendations • Cooperation with other research library sites – on a grand scale
  30. 30. What do people say?“JSTOR meets Amazon!?” - ELUNA twitterer“On May 5, Ex Libris rolled out the shiny new fabulousness that is bX. … (turns) the Services Menu into a point-of- need discovery tool. I think this is awesome. ” - Jamene Brooks-Kieffer, Kansas State Univ.“I found exactly what I wanted. Ive already found even more relevant articles in 10 minutes than Ive found in the last 10 months using more traditional methods of research.” - Ph.D. student, Arizona State University“I’m always trying to find new connections between biological systems. This looks like a really useful tool for this discovery. I’m interested in seeing others’ connections. An unknown system can link to one which is well- studied.” - Laboratory director, University of Ottawa Heart Institute“One thing Ive noticed and got a few comments about is that the increase in amount of recommendations has been noticeable from last summer to now. Now its much easier (to find recommendations). The recommendations seem … relevant” - Systems librarian, FinELib
  31. 31. “The Web, they say, is leaving the era ofsearch and entering one of discovery.Whats the difference? Search is what youdo when youre looking for something.Discovery is when something wonderfulthat you didnt know existed, or didntknow how to ask for, finds you.“Jeffrey M. O’Brien, "The race to create a smart Google“
