Preface The 18th International Conference on User Modeling, Adaptation and Personal ization (UMAP 2010) took place on Big Island, Hawaii during June 20-24, 2010 It was the second conference after UMAP 2009 in Trento, Italy, which merged the successful biannual User Modeling(UM) and Adaptive Hypermedia(AH) conference series The Research Paper track of the conference was chaired by Paul De Bra from the Eindhoven University of Technology and Alfred Kobsa from the University of California, Irvine. They were assisted by an international Program Committee of 80 leading figures in the AH and UM communities as well as highly promising younger researchers. Papers in the Research Paper track were generally reviewed by three and sometimes even four reviewers, with one of them acting as a lead who initiates a discussion between reviewers and reconciles their opinions in a meta-review. The conference solicited Long research Papers of up to 12 pages in length, which represent original reports of substantive new research. In addition, he conference accepted Short Research Papers of up to six pages in length, whose merit was assessed more in terms of originality and importance than maturity and technical validation. The Research Paper track received 161 submission, with 112 in the long and 49 in the short paper category. Of these, 26 long and 6 short papers were accepted, resulting in an acceptance rate of 23. 2% for long papers and 19.9% overall Many authors of rejected papers were encouraged to resubmit to the poster and demo track of the conference Following the example of UMAP 2009, the conference also had an Indus- try Paper track chaired by Bhaskar Mehta from Google, Ziirich, Switzerland and Kurt Partridge from PARC, Palo Alto, USA. This track covered innovative commercial implementations or applications of UMAP technologies, and experi- ence in applying recent research advances in practice. Submissions to this track were reviewed by a separate Industry Paper Committee with 32 leading industry researchers and practitioners. Five long and one short submissions were received nd four of the long papers were accepted The conference also included a Doctoral Consortium. a forum for phd stu- dents to get feedback and advice from a Doctoral Consortium Committee of 17 leading UMAP researchers. The Doctoral Consortium was chaired by Ingrid Zukerman from Monash University, Australia, and Liana Razmerita from the Copenhagen Business School, Denmark. This track received 19 submissions of which 7 were accepted The traditional poster and demo session of the conference was this time chaired by Fabian Bohnert from Monash University, Australia, and Luz Quiroga from the University of Hawaii, Manoa. As of the time of writing, the late sub- mission deadline is still 2 months away, and hence the number of acceptances is still unknown. We expect though that this session will again feature dozens of
