 Hi, everyone. Before we start the presentation, just a quick reminder. In this session, we will be using English as a medium of presentation. But if you need other language support, especially my friends from the Chinese community, you can use a live audio interpretation service using Interactive, as you can see on the screen. And OK, let's begin. Let's begin. Hi, everyone. This is Michael from Chinese Wikipedia. In this session, I will discuss about our game reputation experience, especially about how we implement game-like developments in our context. So first of all, a brief introduction for me. My name is Michael. I'm a Wikimedean since the year 2018. So three years of experience for now. In Chinese Wikipedia, I have organized two editions of our annual contest that we will discuss later on. And also, I'm also a board member of Wikimedia Community User Group of Hong Kong. So anything about Hong Kong or Chinese Wikipedia, you can ask me later on. So first, before we start, let's ask ourselves, what is a content contest? There are some on the screen. You can see some very prominent contests, like Wikilabs monuments, Wikilabs Earths, and Wikipedia Asian mums, and probably many more from our community. But among these content contests, what makes one contest stand out between each other? You may ask. Is that how to distinguish between a good contest and a bad contest? For me, I think that a contest should have a very low barrier of entry. So basically, every Wikimedean or Wikimedean, broadly speaking, can participate without much hurdles. Also, it should be fun to compete in a contest. You don't want someone to be bored out in a contest. And what you intend is make contributing to Wikimedean projects like a game. And also, everyone should be rewarded in some way. Do not only reward a few people who are participating the best, like they have written a lot of articles or they have scored a lot of marks. We try to reward everyone who makes a meaningful participation in a contest. And finally, a contest is not here to entertain the contributors by using a contest or a game like reward method. We would like our final goal is to make a measurable impact in terms of content depth and quality. So in this session, what we are going to do here is to showcase an example of an annual contest run in the Chinese Wikipedia community. The tradition actually starts way before in the year 2006. And it becomes annual traditions in Chinese Wikipedia since the year 2007. In total, until now, we have 19 total editions. With the fifth editions, two of this year's 19 editions are run in an annual fashion. It is, for the time, it is mostly held in the summer vacation period, lasting about two and a half months because according to what we have found, most active participants on our projects are actually fairly many of them are high school or university students. So we choose this time period, the summer vacation. So everyone are easier to participate without much burden in their real life. We try to achieve that. Before the contest begin, of course, we have to organize everything well. The preparation process actually starts two months before the contest. We will initiate a discussion on community discussion forums and we try to organize everything in the way of a deliberative democracy. What does it mean is that we are trying to gain consensus just like how we make decisions in the Wikipedia movement. And sometimes when discussions need some help, I would say, we would use a popular vote to decide on things. But of course, both a discussion and a popular vote are something that complements each other, not replacing it. For the jurors, we will elect about 8 to 10 people who will be judging each article where participants are submitting during the period and also, we will select about 8 specific topics for the participants to write in. These topics are only as encouragement. Participants can submit any articles given that they meet general standards. But they are encouraged to write in these topics so that they can narrow the content gap present in our Wikipedia project. So during the contest time, in the two months time, the participants should... What the participants should do is, of course, to write articles. The barrier of entry is very low. All to confirm users, so-called, they can participate in the contest by just submitting one rally article submission. And the basic requirements for a participant is also very low. It's very easy to complete it, so-called completed. You only have to write two rally articles, and most participants can write much better, some even writing hundreds of articles in one sitting. It's not uncommon. We accept either writing new articles or expansion of existing articles. But every article a participant submits must be of acceptable quality. They must not submit a stop article or something that violates content policies and guidelines. These articles are, of course, not accepted. But this acceptable quality is quite easily achievable. They will only need to write about 3,500 bytes of article contents to be qualified as of acceptable quality. And our scoring is something that makes this contest special. We are scoring participants using an algorithm, not quite like a game, and quite different from other contests, I would say. So how does the algorithm works? We factor five points in our algorithm, including article length, the status of the article. Does it achieve good article or future article status? Of course, if the article is counted as a quality content, they will receive a much better score comparing with other articles. And we factor in the topic of the article. As we have mentioned, we will choose about eight topics in each run of a contest. If a participant writes in-topic articles, they will be scored much higher than other topic articles. We will also factor in any additional contribution apart from the articles. For example, did they shoot any photos or draw any images by themselves? Did they record an audible article for his or her submission? And also, we are favoring slightly on existing articles rather than writing new articles. But generally, most participants will choose to write new articles so that they can have an upper hand, I would say, to choose what topic they are most favored to write in. Of course, with an algorithm, you can't score it by hand. And in two years ago, we introduced a script to help us viewers to calculate scores for each article submission and also updating the statistics of a contest. And the total score earned by each participant will be used to rank them. Other very different aspects of our contest is that almost everyone gets rewarded from participating in this contest. We are not giving out the prizes to only the top score, but we try our best to score everyone. We will give out virtual awards to every jurors, top scorers in total, and also for each selected topics. We will also give awards to new users and also recurrent participants. And by design, about half of the participants will get a reward from their activities in the contest. So talking about this, how did the contest perform? In last year's annual contest, 175 recipients are participating in our contest. About 74% met the basic requirements, that is, writing or expanding two valid articles. We received 1,172 submissions, and 203 of them are considered quality content, including good articles, featured articles, and featured lists. Let's take a look in the article count for each edition since the 5th in 2007. We can see that since 2010, the submission count has been stabilized in the range of about 800 to 1,200 articles. And in recent years, by improving the scoring algorithm, we encourage more quality content, such as featured and good articles. You can see that in the last year's edition, we received 203 quality content submissions. Much increase from what we have seen in 2018, there is only 42 articles. So at the end of this presentation, it will be a Q&A time, and you may ask questions. If there are no questions currently, this will be the end of this presentation session, February 1. If you have any questions after the contest, you can find me on Matter. This is my username. You can ask any more questions.
