 So, the web, you know, there was this kind of pent-up demand. People didn't necessarily realize it, but there was this demand. And as soon as there was a single system that got, you know, wide acceptance, it's like you have 20, 30, 40 years of ideas and ambitions for what you can do with online commerce and connecting people and wikis and online collaboration, etc., suddenly found this expression. So I think a lot of the reason the web exploded is that it kind of allowed and enabled all of these things that, you know, were in the works to suddenly try to find expression. Kind of a dam bursting. Surrendous physics, not computing. The dam bursting analogy is not entirely wrong. Although there was a lot of work being done out there at large and certainly inside a physics laboratory, there was no way that we were going to get full scale resource support for something that was totally accessory to the mainstream of what was doing, what we were doing at some. So it had to get out with the project like the web, where nobody understands you because the only way to make people understand what it is about is to show it to them, to make them experience it. And I said, look, this, as I click here, when I let go of the mouse button, that page is coming from Hawaii. And so he looked at this and I saw his eyes widen and I clicked another one and another page came up with another bunch of dinosaurs. And then he pushed me aside and grabbed the mouse and began clicking himself. When the web came out and you could just very easily with some very simple handwritten in the early days, markup language, HTML, you could make a page and you could make put a picture on the page and make links to other pages. And it was immediately a kind of a revelation. If you wrote a web page and it adhered to the HTML standard, it could be read by anyone who had a browser that could read the HTML standard. And that meant that very quickly we had competing browsers, we had competing websites, we had an open ecosystem that anyone could join. The core question is, what is the value that defines the web? And my belief is that the value is neutrality. And I think the future of the web as this neutral platform will depend on the extent to which policymakers remain committed to that neutrality by resisting the dominance of market players who would compromise that. We need to repair or complement or supplement the infrastructure so as to preserve the basic experience by content providers and users and application providers of this as a neutral platform that encourages innovation and creativity open to all. In the 90s, when everyone was looking for ways of sharing information, the idea was it was all meant to be for the good. It was to open up knowledge. It was to enable communication between people across the world. Everything was all about what we could do for the good. And that feels now as if it's turned on us. The big question is how do we protect ourselves from the bad things without losing all the good things? And this to me is why the web conference is so important. You have to look at it from many different angles, the economics and regulatory systems, the law, philosophy, politics. We need to be discussing how we take the web forward in such a way that it's good for humanity. My name is Layla Zia. I'm one of the general chairs of the web conference 2019. I'm the head of research at Wikimedia Foundation, the foundation that operates Wikimedia and its sister projects. I'm also the co-president of Web for Good, the non-profit 501c3 non-profit organization that organizes web conference 2019. So good morning. I'm Ricardo Baesa-Gates. I'm CTO of intent, semantic search technology company. I have many academic hats in many places. North Eastern here, UPF in Spain, my alma mater in Chile, and also co-president of Web for Good, this small enterprise that allows us to do this. And we are here on behalf of an amazing team of people who have worked with us since 2015 to organize this conference for you in 2019. I ask the team, if you're in the room, please stand up. They have done an incredible amount of work over the past almost four years. I see Evgeny, Ryan, Lang, Fabian, Kirtian. So we are here this year to celebrate the 30th anniversary of the Web with you. As you know, in March, Web turned 30. And we are at a time that more than 50% of the world's population is connected through Internet. So this is an opportunity for us to reflect back, reflect back at the Web that we wanted to build, and at the opportunities that we wanted to provide to people all across the world. We have created a theme for the conference and a program for the conference, which is around the topics which are around openness, inclusivity, balance, and safety on the Web. And in general, we have wrapped everything around the broader topic of Web for Good. I hope you can see the inclusion that we have tried to make this year. And thanks for coming here. We have more than 1,600 people. So that's amazing. We never knew how many people would come and we could do the good prediction at the end. So we have 1640 people and 26% of the students. So I think it's many from industry and many from academia. So thanks to all the sponsors that helped us. So we have Microsoft, Diamond Level, Amazon, Bloomberg, and Google, Gold Level, then CRETIO, AI Lab, Cisco, N10, Spotify, Yahoo Research, and Wikimedia Foundation, Silver Level, then Baidu, Didi, eBay, Facebook, LinkedIn, Megagon Labs, Mix, Mozilla, Netflix Research, Curiculture, Computer Science of North Eastern University, Pinterest, Quora, Visa Research, Walmart Labs at Bronze Level. And also we have the help of Airbnb Let Go, the Moore Foundation, WebCasters, and three publishers. So thanks to all of them. So about the topic of inclusivity, openness, and Web for Good, we have put a program together that can help us reflect on these topics. So generally, there's a lot of reflection and celebration of the anniversary of the web renewing our commitments to an open web and welcoming new audiences. The team has put a lot of effort for opening the doors of the web conference more and more to policymakers, to MDs, to human rights experts. You have seen some of this already in the workshops that happened on Monday and Tuesday, and you will see more of that as we go through the program Wednesday through Friday. And we have also created more opportunities for interactions. These are kind of simple things like extended lunch hours or having social events that you can interact with each other. And hopefully you can take some of the conversations from the program to these spaces and continue those conversations. We introduced more specifically three new programs this year. These are one-day tracks. Today, there is Web of Health, and we will come back to it, introduce it a little bit more in detail. Tomorrow, there's the future of the open web. And on Friday, we have designing an ethical web. We invited keynote speakers who can speak to the theme of the conference and help us align some of the program and our thoughts with the way that they have been innovating in the areas of the web. We also adjusted the call for contributions for workshops, tutorials, and papers to reflect these themes. And we put also more emphasis on student scholarships. So, we'll come back to that later. So, workshop and tutorial were selected by Sihem Ameryajia, Mohamed Madian, and Ashish Goel. So, I think we're ready for some of them. And basically, we selected together 23 workshops with 109 organizers, and the tutorial were 22 tutorials with 45 people presenting them. And also, we have the collocated Web for All traditional event in the first two days of the conference. So, also, on yesterday, we had the big track, which is more like a big data industry track related to the web. And that was organized by Nagesifovsky and Leon Lewin-Eitan, and that was by invitation and had 300 people attending. So, it was a complete success. So, the keynotes, we have three very good keynotes. The first one today, Jeff Dean, doesn't need any presentation. Tomorrow, Claire Wozler, and Friday, Laurence Lessig. Do you want to say something? Yeah. And about the Friday keynote, unfortunately, there was a death in an immediate family member in Laurence Lessig's family. So, they had to cancel the keynote on Friday. It's obviously a huge loss for them and their families. So, our thoughts with Laurence, who worked with us through the past year and a half, he has been really a thought partner for many of the stages that we have been going through the conference as we were planning to organize. Our condolences to him and his family, we are planning for basically the slot that is open. But we just wanted to take a moment to appreciate all the work that he has done and send him our condolences. So, there will be a surprise in the schedule on Friday. So, on Friday, we have the panel to reflect these 30 years of the web. The moderator is Tom Simonite from Wired Magazine. And the confirmed panel is Robert Kaleu, formerly at CERN, and Jamie Thiven from Microsoft. And there will be another surprise. And with this, we're going to turn the mics to Ling Liu and Ryan White, who were the program chairs for the web conference 2019. Please help us in welcoming them. Just one second here while I project. Okay, yes. So, I'm going to talk a little bit about the research program for this year. There are a few things I'm going to go through. The first being what's new this year. We made a few alterations to how we did things. So, I'll speak a little bit about that. A bit about submissions, the PC, and a few more things. To start off with, new this year, we had six-page short papers, which replaced the two-page posters that we'd had before this provided more space to sort of convey ideas. We accepted some of the full papers for talks and some for only posters. This allowed us to have a higher acceptance rate, you know, up to 18% acceptance rate this year compared to 15, I think, in the years before. We gave every paper, either full paper or short paper, the opportunity to present a poster, which they'll be in the afternoon on each of the next few days. We also had full-to-short conversions as well, where we accepted a few full papers that seem to have a valuable contribution. We accepted those as short papers. A bit about the PC. So, we had 12 tracks, a lot of track chairs, but two to three per track. At least one was non-US based, about one-quarter female. 69 SPC members, three of the tracks had an SPC. We left that up to the track, so they could pick if they wanted an SPC or not. 1112 PC members, so a large group, and 594 externals as well. These were people who were brought in either by us or the SPC or the PC to perform additional reviews of the papers. We had about 5,300 papers on average, five per PC member, meta reviews for most papers, all papers had at least three reviews, discussed them in detail, and we had a two-day in-person PC meeting as well. Just a few stats on the papers. So, we received 1,608 submissions, up a bit from last year, 1,200 or so full papers, 360 short papers, and over here on the right hand side there you have the distribution per track. The conflict of interest track was for track chairs who wanted to submit a paper to their own track, so for those PC chairs we took care of those papers. A bit about the geographic distribution of submissions, so mainly from the US and China, but we did have 52 countries represented across six different continents. 65% of papers also had a student as the main author as well, which was great to see, and this is just how it breaks down as well when you get down into the tail. In terms of accepted papers, over on the left hand side is broken out by country, short isn't blue, full isn't green. You'll see again US and China on top there, but a lot of other countries are also there too, which is great. In terms of institutions, a good mix of academia and industry there as well, which is obviously great to see as well. In terms of the acceptance rates, overall we're at 18% for full papers, almost 20% for short per track. There's a fair amount of variation per track, but not a lot, I guess. It sort of ranges from 15% to 23%, right? And short, I think there's probably more variation for as well. Just acceptance rate per country as well, which is also interesting to look at. Austria did the best, quite a long ways, close to 60% of the papers from there got in, and then it drops off from there, but it's really interesting to look at those stats. We also had demos as well, and the PhD symposium too. They were both well attended. I'm going to hand over to Ling now who's going to thank the track chairs. Just more things. Thank you, so just thanks all the technically technical program as reviewers, as track chairs. First, I want to thank all the track chairs. We have 12 tracks and 23 track chairs. Can all the track chairs who are here please stand up? Is it not her? Okay, so I would like to thank all the track chairs. Please all the track chairs stand up first. I can see how many of you are here. Let's give them a round of applause. And basically, I want to talk a little bit about the track chairs because they actually the ones who actually invite PC members and organize their PC teams and managing with all the tracks and paper discussions among the PC members who review the paper and then organize the PC tracks recommendation before they come to Atlanta. We had all the track chair and with Ryan and myself, we sit for two days to discuss the papers. So therefore every paper who get accepted is great paper. Every paper who are not getting accepted this year is unlucky. There are still good papers. So these things can have locks as well. And the next things I want to thank a little bit is the best paper award committee. So do we have all the committee members are here? Please stand up. Let's give them a round of applause. So what we did is during the track chairs meeting and we asked each track to recommend two papers and some track recommended three papers and basically the committee take all these papers. They read it again and they read the reviews. They read the paper again. They select the short list and then they study them again in order to pick up the best paper. So it's a lot of work involved. They did it for a couple months and then they pick up the two best papers, one short best papers. And they are going to be announced at the end of the Friday for the celebration of the 30th year's web and also the award ceremony. So hope people will attend. And next thing that I want to say is there are three important poster track chairs. Are you all here? Please stand up. The poster track chairs? Okay. They are very important because from today we have every day a poster session and we need all of you to vote the best posters as a people's vote. And they are the one organizing the poster sessions and collecting the vote. So you should know their face and work with them and help us select the best posters for the award as well. And I think that's all for the PC programs. Last one I want to all the PC members who served for this conference PC programs, please stand up. How many PC members are here? Please stand up. Let's give them a round of applause. Thank you. Enjoy the conference. No, I just wanted to say with the change that was done in the program committee, we could get to a reasonable acceptance ration. That means more inclusion for two more researchers. Yeah, so we are going to move fast a little bit because we are short in time. I am going to announce we're going to go alternatively announcing the special tracks. Today Web of Health will happen starting 10.30 in Garden A plus B. Attend the event. It's going to focus on health on the web. It's the continuation of many events that has happened as part of the web conference in the past years. The kind of the biggest pitch for this year is that you will have real MDs in the room. So go and enjoy. Tomorrow we will have the future of open web. That's also to reflect the 30 years of the web. And this will happen also in Garden A plus B, then 30 tomorrow. On Friday, you will have the designing an ethical web. That's the special track. And the focus of the track is on the role of technical design and standards on web development and human rights and ethical web. Again, same room, same time on Friday. Student scholarships. Very quickly, we will call them out. We had 15 scholarships for students from the US. They were given to 100%. They were given to women. That was from NSF? Yes. This is an NSF grant. And then outside of the United States, we gave 14 scholarships. 43% were women. The countries that the students were coming from are from Australia, Chile, China, Ecuador, India, and Vietnam. Code of conduct. The conference has a code of conduct. We encourage you to read it. There's a link to it. Please, at a very high level, respect diversity. Do not harass. Do not be part of the silent majority. This means if you see a case of harassment or if you see a case which is kind of not indicating inclusivity, please speak up. And please do not remain silent. Report any issues. The link to where you should report is on the website. Please check. Generally, it's Ricardo and I. You can talk with us. Now we're going to welcome IW3C2 chair Professor Dane Wendy Hall. Oh, I can just do. That's me. Most of you know who I am. I just want to say on that video, I can't believe how old I looked. When I first met Tim and Robert in 1990, I was the youngest lecturer in computer science in Southampton. I'm now probably the oldest professor in computer science in Southampton. It's a bit scary. But I really hope that when I said at the end the web's got to be good for humanity, that means the whole of humanity. And there's a whole 50% of people out there who are not that much part of this community. And this conference has been hugely about diversity. And the next 30 years of the web has got to be about being a very inclusive web. Otherwise, we've failed. That's just my little passion point. Now, I am here as chair of IW3C2, that acronym that rolls off the tongue. I could give a prize for who could say what it stands for. It's the International World Wide Web Conference Committee. And you have to blame Robert Caillou, I think, for calling it that. We have run the conference series since 1994. It was, it is, it was and it is and never was a W3C conference. Jeff is here from W3C. They do their own conferences. They are here. This is an IW3C2 conference. And people run it for us every year. We rebranded last year in Leon. We are now the web conference. And if you say the three-letter acronym, you have to put money in the box. And this, we have long wanted to run a conference in the Bay Area. The legendary Bebo White, who is in the front row here, ran the Santa Clara conference as the conference in 1997 down the road. That was the last time we were in this area. And Bebo helped hugely to get, encourage the team. And as Lila said, they started work on this in 2015. We set our conferences three in advance. Next year is Taiwan. The year after is Slovenia. So in 2015, we started talking about running the conference here. And they thanked everybody else. And I just want to thank Rick and Lila because they have really put themselves on the line for this conference. Absolutely. So on behalf of IW3C2, thank you so much. And thank you for pulling together such a great conference. I don't want to make it competitive, but I think we've already beaten Leon from last year in terms of registrations. Either Leon team or in the front here. So they may disagree when it comes to the stats. Right. I am actually here. Next slide, please, to announce the Seoul Test of Time Award. Now, Seoul and Chin Wan is in the audience here was the chair of the Seoul conference, which wasn't possibly the biggest, but it made a lot of money. And he's put that back into the conference and they have invested in this Test of Time Award. So we were able to present the award every year to a paper that has stood the test of time in terms of where the web is going and the underlying research work that supports the ongoing healthy web. Now, so if we, I'm going to announce now the winners. It is public knowledge. It's on both ours and the conference website. And the winners for this year for 2019 are, the paper was the, can you, is there a slide for this or just, no, just says that. Okay. The paper was the EigenTrust algorithm for reputation management in P2P networks. And the authors were Sapanda, Camvar, Mario Schlosser and Hector Garcia Molino, Stamford University. And Sapanda and Mario are here to collect the, oh, oh, hang on, before you clap, Chinwan, come up to the stage. You're going to present it. Sorry, this is Chinwan. This is the award. We only, my lovely assistant down there brings the awards over, gets them in grade, that each, each of us will get one. We've got one today. I want to take that. So I want to ask Sapanda and Mario to come up and accept the award. Congratulations. Just a few words from the winners. This is a really special award. Just very quickly. No, I can't let this opportunity pass without saying something. Thank you so much for this, Wendy. It's amazing to be here. It's been 16 years since we were in a room like this, presenting this paper. And I think we both were just discussing last night at dinner. We really missed those times. We were both broke, two broke grad students. And I was sleeping on the floor in SEPs in a house that you were renting in Palo Alto with five others. And we just want to get some free music from the web at the time. That was really the gins of this paper. And the PDP networks had kind of gotten clogged up with all kinds of malicious contents. And the serendipity was that we realized we can combine two things. We had totally independently worked on that summer. SEP on page rank, myself on a PDP hash tables and combine them and get something really interesting. And that was great. I think to me is a lesson for life. You have to have more of those random conversations. Hopefully you can have them here at the conference as well. And sleep on more people's floors. That's the other take away there. Thank you very much. And I'll just add one more thing to that, which is we had a tremendous amount of fun writing this paper. And I remember I had been, I was a graduate student and I had had an office to myself. And then one day I got a note saying that I will have a new office mate. And I was pretty upset about it. It turned out that it was Mario. And little did I know that a year later he'd be sleeping on my couch and leaving his Cheerios on my floor and we'd be writing a paper together. And 18 years after we still remain very close friends, one of my closest friends. And so it's the nature of creative research leads to collaborations that lead to close friendships. And that's been a pleasure for me as well. So thank you.
