The previous CollabTech conferences were held in Tokyo in 2005, Tsukuba in 2006, Seoul in 2007, Wakayama in 2008, Sydney in 2009, and Sapporo in 2012.CollabTech2014was co-locatedand organizedwith CRIWG 2014in San- tiago, Chile. CRIWG and CollabTech communities had similar research topics and goals,but had been geographicallylocatedin different regions.We believed this jointendeavorwouldprovideaninteresting opportunity to meet eachother across the Pacific Ocean in the genial spring weather of Santiago. Another change to note was that the proceedings of this conference were published online in the CCIS series by Springer. We hope that this improved the availability and circulation of the presented research. The success of the conference was largely due to the program co-chairs, the conference committee members, and the reviewers whose efforts made the conference possible. The success was also due to the Department of Management and Control Systems andthe DepartmentofComputer Science ofthe UniversityofChile, the SIGon GroupwareandNetworkServicesoftheInformationProcessingSocietyofJapan, the SIG on Cyberspace of the Virtual Reality Society of Japan, and the SIG on CommunicationEnhancementoftheHumanInterfaceSocietyfortheirgenerous support. Hitachi, Ltd. contributed financially to the success of the conference. Wearepleasedthattheconferencewasfruitfulforallparticipantsandplayed an important role in cultivating the community in this researchfield. September 2014 Nelson Baloian Tomoo Inoue Hiroaki Ogata VI Preface Message from the Program Chairs After six events in the International Conference on Collaboration Technologies series, we had the seventh edition (CollabTech 2014) in Santiago, Chile. The following topics on collaborationtechnologies were discussed: - Collaborative Problem Solving - Knowledge Work and CSCW Tasks - Co-Dining Support - Augmented Reality and Robots - Learning Support Systems For this conference, we received 34 submissions (24 full papers, 10 short papers) and assigned three reviewers per full paper or two reviewers per short paper.Asaresult,wehadtenfullpapersandfourshortpapers.Theacceptance ratewas41%.The acceptedpapersrepresentedeightcountriesfromalloverthe world, reflecting the international recognitionof CollabTech 2014. Without ourdistinguishedProgramCommittee members, we couldnothave maintainedourhighstandards.We truly appreciatedtheirdevotion.Finally,we hoped that these proceedings serve as a reference for future researchers in this rapidly evolving field.

Ulrich Hoppe Departmentof Computer Scienceand Applied Cognitive Science Faculty of Engineering, Universityof Duisburg-Essen BuildingLF, Lotharstr. 63/65 47048 Duisburg,Germany [email protected] Abstract. In the area of computer-supported collaborative learning (CSCL), the methodology of social network analysis (SNA) has been usedtoidentifyrolesandinternalstructuresinlearninggroups.SNAhas become an important tool to provide information and insight for man- aging learning communities. It is still a challenge to combine SNA with other techniques focusing on the analysis of content in learner-created artefactsorontheanalysisoftime-dependentpatternsinlearneractivi- ties.Severalexamplesofapplyingsuchanalysestolearningenvironments andcommunitieswillbegiven.Also,ageneralweb-basedworkbenchfor creatingandperforminganalysisworkflowsofdifferenttypeswillbepre- sented. From a systems engineering point of view, the question of how to integrate analytics modules with existing learning environments and community platforms will beaddressed.
