Microtask Crowdsourcing Marketplace for Social Network

Crowdsourcing is a powerful way to process and collect data that needs human's logic and perception. Crowdsourcing can take part in many hard to compute problems such as data entry, multimedia transcriptions and many case of artificial intelligence. While this is a powerful approach, crowdsourcing needs a relatively large marketplace to works optimum. In context of Indonesia, we hardly hear about task crowdsourcing even though there are some marketplace like poin-web.co.id. In this paper, we propose a social network for crowdsourcing marketplace to penetrate the market. People tends to waste most of their time on social network and game rather than other mobile application in case of mobile usage. The idea is to make crowdsourcing as a filler while people are using social networks like waiting for a chat or scrolling the timeline. And by applying microtask as the task, people will not have much burden on doing the task. On the other hand, he/she will get additional income. We implemented LINE as a basis of our social network marketplace. LINE does provide the most interactive way of provide message. Additionally, the user of LINE in Indonesia is growing in a fast pace. We conduct an experiment focused on worker's coverage and ease of use. By using usability testing as a basis of ease of use evaluation, we received good feedbacks as 90.9% of the users feel easier to answer through LINE and is excited to use the platform in case it goes with real money.
