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.

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

MangoSub

Members: Sungmin Choi, Wonkeun Choi, Muso Mukayumkhonov, Zhantore Orynbassarov

While many platforms offer subtitles for popular shows, resources are limited for non-native English speakers to obtain subtitles for less well-known shows, video lectures, or even self-filmed videos. MangoSub offers a crowdsourcing solution for users to request subtitles for their videos to be completed by other users. What’s more, it offers simple, modular transcription tasks for users to practice their listening comprehension while contributing to subtitling other users’ videos.

Moody

Members: Thao Vu Phuong, Jiyoun Ha, Kamil Veli Toraman, Bolat Ashim

"Somebody out there gets you."
3 out of 10 Koreans suffer from mental disorder, yet stigma and lack of awareness worsen this problem. We introduce Moody, where users can log and become aware of their current mental status and empathize with others to build an understanding community. Moody allows users to share and empathize via a novel approach of psychologist-proven 2D graph of emotions.

Melodize

Members: ChanJu Chong, HyoungWook Jin, JaeHoon Choi, WooJin Lee

Lyricists don’t necessarily have the skills to compose melodies to their lyrics, and laymen don’t have opportunities to realize their compositional ideas. We propose ‘Melodize’, a platform where crowd workers compose melodies onto lyrics submitted by lyricists. Our platform is unique in that we are applying crowdsourcing to the arts, and our composition method is to be based on pre-existing lyrics.

Mapit

Members: Nam Ung Kim, Andreas Erwin Poppele, Adil Karjauv, Adi Yerembessov

The problem: Some students would like to have their summaries well-structured and be able to collaborate with others while creating their summaries.
The solution: On our platform, students can collaboratively create summaries as structure maps in real-time.
Unique approach: The structure maps proved to be very effective for studying and are not used in any platform so far.

PhotoCal

Members: Lucas Ochoa, Gautam Chandra Bose

We are addressing two main problems, first that when we see interesting posters around campus we may not add them to our calendar due to the fact that we are in a hurry, and second that we only find out about events that are advertised around our day to day activities. Our solution is a mobile application that allows you to snap a photo of a poster, and others who benefit from seeing the poster will label it into an easy to use calendar event. Our approach is unique because it not only provides an easy workflow for labeling, but also provides a digital database of events that was not previously avaliable.

눈치백단

Members: Sohee Kim, Ina Ryu, Hyunwoo Kim

Sometimes, it is hard to get the true meaning of conversation from chat over messengers. Since contexts are created by social consensus, often it is easier for other people to get the contextual meaning. So, we made a simple service to ask question about the true meaning/intention of the conversation, and have it answered by crowd to get more reliability.

In Kakao Talk, add "눈치백단" as Plus Friend.

KAKAO TALK MOBILE KOREAN

Dike

Members: Dongkwan Kim, Hyeungshik Jung, Hyungyu Shin

We aim to paraphrase written judgment to enhance readability by crowdsourcing workflow. We introduce Split-Polish-Connect-Revise workflow for the paraphrasing. It doesn’t require experts for paraphrasing, which could reduce the cost to make more readable written judgments.

SwiftyQ

Members: Kyung Je Jo, Chae-Ryn Chang, John Joon Young Chung

Question-answer websites are often too slow to answer and do not allow direct interaction between the requester and worker. SwityQ is a real-time chatting Q&A interface in which the requesters can actively ask questions directly to the workers who will help them understand the problem. The application allows for fast and accurate answers by sending emails once a request is paged and encouraging workers through an entertaining achievement system.

KAI'STEER

Members: Simon Dybdal, Sovanny Kaarina Huy Nikkila, Olzhas Kadyrakunov

Students - as the daily users of campuses - and their opinions are rarely taken into consideration when decisions and changes are made on university campuses. Our proposed solution is to enable students to raise awareness of what matters to them, enable students to show their support towards other’s issues and then make sure that popular issues get brought forward to the right decision makers. The “nothing to lose, all to win”-mentality coupled with the extremely quick and easy contribution cycles grounded in the platform can incentivise students to become active users.
