It is our great pleasure to welcome you to the 10th ACM Conference on Web Science, Amsterdam, 27-30 May 2018. This year's edition of the WebSci conference (WebSci'18) celebrates the ten year anniversary of the unique conference series where a multitude of disciplines converge in a creative and critical dialogue with the aim of understanding the Web and its impacts. The WebSci conference brings together researchers from multiple disciplines, like computer science, sociology, economics, information science, anthropology and psychology. Web Science is the emergent study of the people and technologies, applications, processes and practices that shape and are shaped by the World Wide Web. Web Science aims to draw together theories, methods and findings from across academic disciplines, and to collaborate with industry, business, government and civil society, to develop our knowledge and understanding of the Web: the largest socio-technical network in human history. This year we were very pleased to receive 113 submissions for the regular research track. Given the high quality of submissions, it has been a hard job to decide which of the contributions to select for the conference. We are grateful for the support of the Program Committee which consisted of 10 senior members and 35 regular members. All PC members worked hard, based on which we could select an interesting, varied, exciting program comprising 30 long and 15 short papers.

An enthusiastic welcome to the 2018 ACM SIGSIM Conference on Principles of Advanced Discrete Simulation (PADS 2018), the 32nd for the PADS series, which this year is held in Rome. Building on its long successful history, this year the conference attracted high quality submissions on a range of topics on modelling and simulation. In total, forty six (46) submissions were submitted, thirty three (33) as regular papers and thirteen (13) as short papers. Following the rigorous double blind reviewing tradition of PADS, every paper received at least three (3) reviews. All papers and their reviews were then discussed extensively at a Programme Committee meeting that took place on the 2nd of March, 2018. Based on the deliberations of the Programme Committee, fifteen (15) papers were finally accepted as regular papers and eight (8) as short papers. Three (3) regular papers were conditionally accepted and were assigned to three shepherds respectively, who supervised their revision to a successful outcome. PADS has a long tradition of embracing the work of early career researchers as well as new ideas and cutting edge research which is in progress. A PhD Colloquium and a Poster session will showcase these exciting ideas. A significant recent development is the participation of PADS in the ACM Reproducibility Initiative. Evaluation of artifact and results replication was handled by a separate Reproducibility Committee. From the originally submitted papers, sixteen (16) regular and five (5) short papers opted for reproducibility evaluation, which is a very encouraging sign and suggests that our community is embracing this important initiative. From the finally accepted papers, five (5) regular and five (5) short have been further evaluated for reproducibility. Four (4) papers that ranked most highly by the reviewers were nominated for the Best Paper Award and were further considered by a panel to select the best paper for PADS 2018. The nominees, in no particular order, are:Fast-Forwarding Agent States to Accelerate Microscopic Traffic Simulations, by Philipp Andelfinger, Yadong Xu, Wentong Cai, David Eckhoff and Alois KnollComparing Dead Reckoning Algorithms for Distributed Car Simulations, by Youfu Chen and Elvis S. LiuPorting Event &Cross-State Synchronization to the Cloud, by Matteo Principe, Tommaso Tocci, Alessandro Pellegrini and Francesco QuagliaSimulation Study to Identify the Characteristics of Markov Chain Properties, by Atiqur Rahman and Peter Kemper

The ASPLOS'18 program is the result of a thorough evaluation process, which we started by forming the program committee (PC) with 50 members and the external review committee (ERC) with 73 members. Moreover, we split up the PC into two independent sub-PCs while keeping the ERC as a single unit. We carefully assigned the PC members to the two groups, ensuring that (1) each sub-PC would cover all ASPLOS topics and (2) the experts on each topic would be evenly split across the sub-PCs. In response to the call for papers, we received 319 submissions, just one shy of last year's record. (This number includes 18 submissions that were either withdrawn by their authors or desk-rejected for clear violations of the formatting rules.) After receiving reviewing bids from most committee members, we also split the submissions evenly across the two sub-PCs, so that each submission would receive reviews from only one sub-PC. We manually moved submissions across sub-PCs to maximize reviewer expertise, according to the PC members' bids. The review process proceeded in two rounds, followed by an extensive online discussion period. During the first round, all submissions received 3-4 reviews. Based on these reviews, we selected 158 submissions to go through the second round of reviews, which produced 2-4 additional reviews for these submissions. During the review process, we also requested reviews from 52 external experts on a case-by-case basis. Throughout the process, our main goal in assigning reviewers to submissions was to maximize reviewer expertise. Overall, the committees and external experts produced 1,227 reviews. After the online discussion period involving all reviewers, we selected 100 submissions for discussion (15 papers online-tagged tentative-accepts and 85 papers online-tagged discuss-at-meeting) during the PC meeting on November 10, 2017 at Georgia Tech. 47 of the 50 PC members were physically present at the meeting and 2 others participated remotely. The whole committee met together in the morning, and split up into the two independent sub- PCs in the afternoon. We did not set a limit for the number of accepted submissions. During the meeting, we accepted 47 submissions and conditionally accepted (subject to shepherding) 9 others. After carefully addressing the reviewers' comments, all shepherded submissions were ultimately accepted. The acceptance rate of the two sub-PCs was exactly the same: 28/151 and 28/150. To complete the program, we invited two outstanding keynote speakers: Hillery Hunter (IBM Research) and Fred Chong (University of Chicago). We are pleased that the 56 accepted submissions and 2 keynote talks represent an exciting spectrum of traditional and emerging ASPLOS topics.
