It is our great pleasure to welcome you to New Brunswick, New Jersey and the third ACM SIGIR Conference on Human Information Interaction and Retrieval (CHIIR 2018). CHIIR, as you may know, has roots in two previously successful communities: The Information Interaction in Context (IIiX) conference and the Human Computer Information Retrieval (HCIR) symposium, which ran from 2006 and 2007 respectively. These meetings were focused on issues that involved Human Information Behavior (HIB), Interactive Information Retrieval (IIR) and Human-Computer Interaction (HCI). Those roots, as well as decades of research and development on information seeking and other forms of information interaction, human-centered design, and information retrieval are the backbone of CHIIR. At the same time, this vibrant new community has picked up more scholars and themes as it continues to attract new students and professionals, as well as emerging research topics that are evident in this year's program. In fact, CHIIR is one of the few forums that explicitly supports presentation of bold new ideas through its Perspective Papers category. In addition, we have picked up Demos as a new category for presentations this year. All of these wonderful things could not be possible without a large number of people making significant contributions. We are quite fortunate to have Katriina Byströouml;ouml;m, Falk Scholer, and Jeff Huang as our Program Chairs this year. These three brave souls took upon a tremendous effort of working with dozens of submissions, reviewers, and meta-reviewers and constructing a high-quality program while coordinating from three different continents. Soo Young Rieh and Preben Hansen, on the other hand dealt with higher than expected load for short papers and still managed to get them reviewed and assessed on time. Even our Doctoral Consortium (DC) this year ended up being quite challenging as we received twice as many submissions as before, but our fine DC chairs Jaceck Gwizdka and Vivek Singh found world-class mentors for these doctoral students. Thanks to our Workshops and Tutorials Chair Xiaojun Yuan, we have a fantastic lineup of tutorials on the first day and workshops on the last day. When the whole program was ready for the conference, it was our Proceedings Chair Roberto Gonzalez-Ibanez who managed to put together these proceedings that you are holding in your hands, or more likely viewing in the ACM Digital Library! We are thankful for having an energetic and resourceful local arrangement committee with Michael Cole as the Treasurer, Fernando Diaz as the Sponsorship Chair, Kaitlin Costello as the Local Organizing Chair, and Sunyoung Kim and Matt Mitsui as the Student Volunteers Chairs. And it was our Publicity Chair Anita Crescenzi, who helped us with not only the outreach efforts, but also with the registration system. Finally, none of these would have happened without the authors and reviewers from more than 30 countries whose contributions are reflected in every aspect of this conference. So, thank you all!

We are delighted to welcome you to the Eleventh ACM International Conference on Web Search and Data Mining (WSDM 2018) held in Los Angeles, California, USA, on February 5-9, 2018. Now in its eleventh year, WSDM has become a top tier conference in Web-inspired research relating to search and data mining. As in previous years, we continued observing a growth in number of submissions. The conference this year, with 514 valid submissions, maintained the major boost that was observed last year in Cambridge UK (with 505 submissions as compared to 386 in year 2016 in San Francisco). Interestingly, we saw an increase in 10% in abstract submissions with a record breaking 757 abstracts (as compared to 687 in 2017) but only 68% of those ended up as valid submissions. This is partly due to a relatively high number of invalid submissions that did not adhere to our new double-blind review policy. The 514 valid submissions originated from 41 countries, out of which 84 (as compared to 80 in 2017) were accepted for full paper publication in the proceedings, thus reaching an acceptance rate of 16.12% (as compared to 15.94% last year) and within the range of the last 11 years (with a min of 15.5% and a max of 22.3%.) Unfortunately, three papers were withdrawn/rejected after acceptance due to their violations of WSDM guidelines. The final 81 papers that will be published in the proceedings are from 23 countries, spanning four continents, making this a truly international forum. Oral presentation slots were allocated to all papers. Yet, in order to maintain the single track model that most attendees prefer, we followed the spotlight short presentation plus poster approach that was introduced in 2012. Out of the 81 accepted papers, 58 were assigned such a two-minute spotlight slot, while 23 were assigned a long twenty-minute talk slot. The type of slot was chosen by the Senior PC members and Program co-chairs, mostly based on whether the topic and the content of the paper were best suited for a large group presentation or for a more focused and interactive poster style of presentation. The double-blind flavor we adopted this year allowed the authors to indicate the source of their data set, or deployment environment (so as not to refer to major commercial search engines as has often been done in the past). However, we observed that several authors failed to indicate their conflict of interest (COI) adequately and we will make sure to enforce COI guidelines (through both awareness campaigns and hopefully automated tools) more rigorously now that the double-blind review policy has been adopted.

It is our great pleasure to welcome you to Seoul, Korea, for the fifth edition of the ACM International Conference on Interactive Experiences for Television and Online Video - ACM TVX 2018. We are certain that this is a great place to meet diverse research and industry communities from around the world, including those that have not previously been heavily involved in the TVX conference series. As such, we are incredibly excited to be able to present a stimulating program for ACM TVX 2018 in an equally magnificent part of the world; incidentally representing a first for this conference series - a host city in Asia! As the leading international conference for the presentation and discussion of research and developments into interactive experiences for online video and TV, the conference brings together international researchers and practitioners from a wide range of disciplines, ranging from human-computer interaction, multimedia engineering and design to media studies, psychology and sociology, to present and discuss the latest insights in the field. The ultimate mission of the conference is to share novel ideas, concepts, and solutions that fulfill the needs of new media environments and identify new directions for future research and development. This year's conference continues its tradition of being the premier forum in this field, following the success of the four previous editions of TVX (held in Hilversum, Chicago, Brussels and Newcastle upon Tyne), and building on the legacy of the EuroiTV conference series organized all across Europe, between 2003 and 2013. We continue to present research on topics in scope such as immersive experiences, user experiences & interaction design, content production, systems & infrastructure, devise & interaction techniques, media studies, business models & marketing, and innovative concepts & media art. In addition, we introduced two hot topics to the call for papers associated with ACM TVX 2018: AI/Big Data and Social Computing. The call for papers attracted 36 long and short paper submissions from Asia, Europe, North & South America across both academia and industry. Being the first edition in Asia, it received new submissions from China, Japan, and Korea which were less visible in the conference series until now. All submissions went through a rigorous double-blind peer review process. Each paper was assigned a primary Associate Chair (AC) and a secondary AC. The primary AC recruited at least two reviewers for each of their assigned paper, whilst the secondary AC recruited at least one reviewer for their assigned paper. Once the reviewers submitted their evaluation of the suitability of the paper, the primary AC wrote a meta-review summarizing the main points of each review. Authors of the submissions were then notified of the completed review and given the chance to respond to the reviewers' comments during a rebuttal phase. During the TPC meeting on March 16, 2018 in Lisbon, Portugal, each paper was discussed in-depth with the ACs, and the final decision on the accepted papers was made, resulting in a high-quality program of 12 accepted full and short papers, accounting for an acceptance rate of 33%. Full papers, Short papers, the abstracts of the 2 Workshops co-located with TVX (in addition to an industry workshop close to the public), and the 17 Work In Progress papers are part of the main proceedings and will be included in the ACM Digital Library. In addition to these submissions, there were several other tracks that attracted a considerable number of contributions, resulting in 8 TVX in Industry presentations, 8 Demonstrations, 3 Doctoral Consortium papers, and 2 Grand Challenge presentations, all made available in the adjunct proceedings, along with the papers from the Wo

On behalf of the organizing committee, it is our great pleasure to welcome you to the historic city of London for the 24th ACM Conference on Knowledge Discovery and Data Mining - KDD 2018. These are very exciting times for our community. The terms Data Science, Artificial Intelligence, Machine Learning, Data Mining and Big Data have, in the last few years, grown out of research labs and gained presence in the media and in everyday conversations. We hear these terms on social media and from decision makers at various level, both in governments and corporations. The impact of these technologies is felt in almost every walk of life with novel applications in self driving cars, AI assistants and in the discovery of new cures. Importantly, the current rapid progress in data science is facilitated by the timely sharing of newly discovered approaches across research and industry. It is the hallmark of KDD conferences in the past that they have been the bridge between theory and practice, a great facilitator and catalyst for this exchange. Researchers and practitioners meet and interact in person over several days. Our program, with its keynotes and interactive tutorials, is designed to bring these two groups together. It is also a very exciting time for London, which has recently been named as the the AI capital of Europe. We could have chosen no better place to host this year's conference. London is home to more than 750 AI companies, operating in more than 30 industrial sectors, with almost half of these enterprises having a non-UK founder, and about a third with founders from a minority background. It is also home to many world-leading academic institutions and research centers. This confirms London's international and open nature as a leading hub for innovation and technology. The conference this year continues with its tradition of a strong engaging and hands-on program including a full day of tutorials on Sunday and plenty of cutting edge workshops on Monday. The final three days are devoted to peer reviewed contributed technical papers, describing both novel, important research contributions, and applied, innovative solutions. Four stellar keynote talks, by British Academy Fellow David Hand, Nobel Laureate Alvin E. Roth, Columbia Univ. Data Science Director Jeannette M. Wing and Oxford University Professor Yee Whye Teh, will touch on some of the important, emerging issues in the field of data mining. With a growing industry around AI, our KDD Panel brings together experts to spawn discussions and exchange ideas about how AI can be used for social good. We have an outstanding lineup of industry speakers sharing their experiences and expertise in deploying industrial data mining solutions. Thanks to a strong hands-on tutorial program, participants will learn how to use practical data science tools. KDD 2018 puts a strong emphasis on AI development with mainstream applications featured by KDD Cup of Fresh Air with 4173 teams around the globe participating in a challenge to predict air quality in cities like London and Beijing; a unique Deep Learning day, with world class research leaders addressing the frontiers in deep learning research and applications; and a Global AI Initiatives Session where major government initiatives in AI will be presented by representatives from various countries including UK, USA, China etc. We hope that the content and the professional networking opportunities at KDD 2018 will help you to succeed professionally, identify new technology trends, learn from contributed papers, presentations, and posters, discover new tools, processes and practices, identify new job opportunities and hire new team members.

It is our great pleasure to welcome you to the 2018 ACM International Conference on Hypertext and Social Media (HT 2018) in Baltimore, Maryland, on July 9--12. HT is a top-tier ACM conference in the areas of Hypertext and Social Media. Since 1987, it has successfully brought together leading researchers and developers from the community. It is concerned with all aspects of modern hypertext research, including social media, adaptation, personalization, recommendations, user modeling, linked data and semantic web, dynamic and computed hypertext, and its application in digital humanities, as well as the interplay between those aspects such as linking stories with data or linking people with resources. HT 2018 continues to create an outstanding technical program consisting of research and demo paper presentations. The single-track conference brings together researchers working in topics including Algorithms and Methods for Social Media Analysis, Digital Humanities and Computational Social Science, Adaptive Hypertext and Recommendations, Semantic Web and Connected Data, Digital Storytelling and News, and Collaboration and Crowdsourcing. In total, we have received 69 regular paper (10 pages) submissions reviewed by a group of 66 regular and 33 senior program committee members, who led the discussions. In the end, 19 regular papers (acceptance rate of 27%) were accepted with another 10 full papers accepted as short papers. Additionally, 3 of 16 short paper submissions were accepted. This year, for the first time, we also organized a Blue Sky Ideas track with the support of the Computing Community Consortium (CCC). This track received 5 submissions of which 3 were accepted and received partial travel support from CCC. To help provide a broad perspective on current trends at the intersection of data science and society, the conference will host the following four, diverse keynote speakers: Leslie Sage, the Director of Data Science at DevResults; Seth Stephens-Davidowitz, the author of the NYT bestseller Everybody Lies; Elizabeth Kittrie, a Strategic Advisor for Data and Open Science at the National Library of Medicine (NLM); and Ben Zhao, the Neubauer Professor of Computer Science at the University of Chicago. In addition to the scientific presentations and the keynotes, the pre-conference day on July 9 will also feature three focused workshops and a tutorial.
