Project Gallery: Voluntary Crowdsourcing / Social Computing Applications

Students worked on a semester-long design project, in which they designed and built a crowdsourcing / social computing application that involves a VOLUNTARY OR INTRINSICALLY MOTIVATED CROWD. This poses interesting and unique design challenges in terms of task design, incentive design, and quality control.

Twelve student teams came up with creative designs, and this page gives a snippet of their design process.

CrowdReact

Members: Narae Cha, Jisu Han, Yujin Kim, Jeongho Won

In mass audience events, it is difficult for attendees to share feelings with the audience in real-time. CrowdReact enables (1) to express real-time feeling (2) to share visualized feeling (3) to archive event with feelings at that time. CrowdReact can (1) help express various feelings of audiences than simple applause and cheer, (2) make the user feel a sense of identity and empathize with the audience by looking at others’ expressions, and (3) record feelings expressed in real time.

TroubleShooter

Members: Seonju Lee, Hyeongrok Ham, Yeonsu Kim, Saebom Jeong

Some people feel uncomfortable and stressed when they should decide something and do not have much time. In this situation, it is helpful to give advice from many people quickly. We chose to use a chatting-window-like interactive interface and to show a real-time voting result so that users participate actively in order to persuade others.

EVENTENCES

Members: Kinam Park, Seyeon Kim, Changsu Ham, Dukwha Kim

Many campus events are opened in KAIST, but not a lot of students attend because they do not receive enough information to determine if the event is appropriate for them. Our project, “EVENTENCES” collects keywords from users(volunteers) who will complete sentences about events using Crowdsourcing, and it recommends events to other users through the sentence that was made by these keywords. We have differentiated our product from other promotion methods by bringing in users’ participation through playable activity and discovering hidden audience through more intuitive recommendations.

fresherTalk

Members: Jibon Naher, Brandy Lee, Yueru Tu, Arjun Kumar

KAIST international students often have questions that need answers related to KAIST life, some of which need immediate answers. Our solution to this problem is a Q&A platform where international students can post questions, answer questions by other students, and notify others of their urgent questions. Students can subscribe to topics that they are interested in, and are notified when new questions in the category appear, which allows the platform to find answers to urgent questions quickly.

CrowdVerse

Members: Nyoungwoo Lee, Keon Lee, Yoonseo Choi, Evey Huang

People from different countries are often used to only read their local news sources and local people’s opinions, thus lack the understanding of perspectives and opinions from other countries. WIth Crowdverse, we aim to encourage the crowd to explore, collect, and discuss about information sources and opinions from other countries that may have different perspectives and stances. The unique aspect of our approach comes from the crowd -- with people who may be coming from anywhere in the world, we are hopeful to aggregate as diverse as possible opinions and perspectives.

XCollab

Members: Ern Chern Khor, Gabriel Lima, Oguz Serbetci, Thu Nguyen

Students who are studying for an exam may be stuck on a problem or want to discuss a topic more in-depth but they have a hard time to do so because they may not know anyone who is on the same page as them. We introduce XCollab, where they can find, discuss and practice exercises with other students around the world online. In XCollab, students are motivated to think by themselves and participate in discussions by our unique coin and mastery system and are able to acquire knowledge better by our discussion summary feature.

AnoBoard

Members: Peerapon Akkapusit, Wasachon Chaisirirat, Duc Huy Do, Peter Mushick

Due to shyness, discomfort, and inconvenience, classmates that have never known each other outside the classroom before are not likely to initiate or join in a conversation even though they participate in class sessions together for a considerably long time. These issues are addressed with Anoboard: an application, which gives strangers the possibility to contact each other anonymously by posting their messages on each other's personal boards without their identity. The secret ingredient of our application is anonymity, which can allow us not only to discover and encourage new and extraordinary interactions but also help users to overcome their social barriers.

GradBridge

Members: Dongmin Lee, Saelyne Yang, Junyoung Park, Sangjin Choi

To reduce the information gap amongst applicants of KAIST graduate school regarding admission procedures, we gather experiences of previous applicants and present the gathered data in an effective way. Applicants first collaboratively structure the informative contents of the admissions and then share their personal experience on each of the contents. Unlike informative documents which only contain the objective information or personal blogs where applicants only share their personal experience, we provide a hybrid approach where both objective information and personal experiences are shared.

To-gather

Members: Minji Lee, Sihyun Yu, Juan Lee, Sungwoo Jeon

While reading some materials, discussion with people is necessary to fully understand the content, but in most Q&A platforms, only questioners want to ask a question but answerers feel bothersome to the question which makes only one-direction interaction. In order to encourage people to answer more, we make the direct chain questioning system that makes people feel obligated to reply more than before and also make the system to represent the relationship between the questioner and answerers like 'I answered your question before' or 'We are in the same grade' by one sentence. Other question/answer platforms that already exist mostly value the professional presence of respondents and they use ways of rewarding users to increase user's chances of responding (e.g., Naver Knowledge iN), but we focused on the relationship between users to make feel like being friends so finally encourage the answer.

Cactus

Members: Viktoriya Kim, Mathias Sixten Pedersen, Willmer R. Quiñones, Yixuan Huang

In an education, daily motivation can be a big problem for students to reach a desired goal. We have implemented a prototype for micro-goal setting where the user can set small goals, which will automatically be shared on a public feed, that can then be used to provide feedback for others, or gain inspiration from other’s goals. To keep users motivated, they will have to take care of their own little Cactus, which will only grow upon completing tasks, and participating in the public feed.

WORK OUT

Members: Mingyeong Kim, Zelalem Belay, Yunho Choi, Yong-Jun Shin

There are many people who like sports but who have difficulties in finding a friend to play with. WORK OUT is a matchmaking system which provides both manual match finding and automated match recommendation considering the user's skills or preferences. To promote exercising and reduce burdens to find an opponent player, it recommends a match for users and also provides a social environment to find a good player with reputation, comments, and ranks.

DebNet

Members: Viet Do, Anh Le, Van Hoang, Doyeong Kim

The debts connection among a group of friends can be quite complex, due to occasions like eating, movies, etc. and one person pays everything and others will repay later. DebNet helps manage these connections by summarizing the total amount of money, memorizing the events and listing the debts. Furthermore, DebNet has unique user profile where statistics (e.g., number of transactions) are showed.
