The conference is supported and governed by the CollaborativeResearchInternationalWorkingGroup(CRIWG),anopencommunityof collaboration technology researchers. Since 1995, conferences supported by CRIWG have focused on collaboration technology design, development, and evaluation. The backgroundresearchisinfluencedbyanumberofdisciplines,suchascomputerscience, management science, information systems, engineering, psychology, cognitive sci- ences, and social sciences. The 26 submitted papers were carefully reviewed through a double-blind review process involving three reviewers appointed by the program chairs. In all, 11 sub- missionswereselectedasfullpapersandeightwereselectedasworkinprogress.Thus, this volume presents the most relevant and insightful research papers carefully chosen among the contributions accepted for presentation and discussion at the conference. The papers published in the proceedings of this year’s and past CRIWG conferences reflectthetrendsincollaborativecomputingresearchanditsevolution.Therehasbeen a growing interest in social networks analysis, crowdsourcing, and computer support for large communities in general. As is the tradition at CRIWG, the collaborative learning topic this year was also a prominently represented topic with four papers selected covering this topic in one way or another. This year there was strong partic- ipation from Chile and Germany, each having five papers. Also this year we also saw the growing participation of Japan and newcomers like Qatar and of course Armenia. There were also contributions from the USA, Canada, Brazil, and Spain. As editors, we would like to thank everybody who contributed to the content and production of this book, namely, all the authors and presenters, whose contributions made CRIWG2015 asuccess, aswell astheSteeringCommittee, themembers ofthe Program Committee, and the reviewers. Last but not least, we would like to acknowledge the effort of the organizers of the conference, without whom this con- ferencewouldnothaverunsoeffectively.OurthanksalsogotoSpringer,thepublisher of the CRIWG proceedings, for their continuous support.

Recommender systems are one of the “hottest” areas for companies that offer items to end users and have a wide scope of applications, from commercial, throughentertainmenttoeducational.Mostrecommendersystems are based on implicit or explicit models of user behaviour, including user rat- ings, click streams or navigation paths, or complex knowledge structures derived through reasoning from user input data. They deploy various person- alization algorithms to adapt the recommendation to the user’s interest and context. The current recommendation algorithms have advanced to a stage wheretheyofferveryhighaccuracyinpredictingwhichitemstheuserwilllike. However, the resulting recommendations are not always accepted well by theusers.Sometimesusersprefernottosharetheirdatawiththesystembecause ofprivacyconcerns,ordonottrustthesystem’srecommendations,especiallyif theydonotunderstandhowtheyweregenerated.Togaintheuser’strust,itis important to explain the main principles or mechanism that the recommender system uses; however an explanation would increase the cognitive load of the userandthereforewouldnotbewelcome.Avisualizationofthemechanismor its main principles may be helpful here, since “a picture is worth a thousand words” and it can save users’ time and efforts by showing an intuitive and understandable representation of the recommendation mechanism. This talk will give an overview of some of the existing approaches (both from the speaker’s own research lab and from other authors) for visualizing recommendation mechanisms and eventually allowing users to control these mechanisms.Startingwithworkfromtheareaofopen/scrutablelearnermodels in the area of intelligent tutoring systems, through approaches for explaining recommendationstoapproachesvisualizingaspectsofcollaborative,hybridand social recommenders, the talk will focus on approaches for visualizing social recommendation in streams of socialsites updates.
