CHIIR
It is our great pleasure to welcome you to Glasgow and to the Fourth ACM SIGIR Conference on Information Interaction and Retrieval (CHIIR'19). The number of contributed papers and short papers, and the number of conference attendees, clearly demonstrate the value of this unique forum for researchers and students interested in the user-centered aspects of information interaction and information retrieval. We are very pleased to see a great range of topics and institutions represented in the programme for this edition of the CHIIR conference series. We would like to thank the people and institutions who have contributed to making CHIIR'19 a success. We first thank the authors for providing the content of the conference program. The three Program chairs, Hideo Joho, Vanessa Murdock and Pernilla Qvarfordt invested a huge amount of time and effort in organizing the paper reviewing and selection process for the full and short papers, and in putting together a very interesting program, with the help of the Senior Program Committee and the Program Committee. We are grateful for the efforts of the Tutorial Chair, Catherine L. Smith, the Workshops Chairs, Stephann Makri and Suzan Verberne, the organizers of the Doctoral Consortium, Yashar Moshfeghi and Heather O'Brien, the Demos and Resources Chairs, Jiyin He and Frank Hopfgartner, the Publicity Chair, Diane Pennington, and the Publications Chair, Craig Macdonald. We also very grateful to Mateusz Dubiel and Sylvain Daronnat, for leading the student volunteers and for all their support with our webpages. Finally, we thank the hosting organization, the University of Strathclyde, for their practical support we could wish for, our colleagues at the Technology and Innovation Centre for help with all the logistics of the conference, and the City of Glasgow for inviting us into the City Chambers for the welcome reception. We hope that you will find the program interesting and thought-provoking and the interaction with old and new friends and colleagues engaging and stimulating, - and that you will enjoy the city of Glasgow!
