IGATA: An AttractionBased Online Task Recommendation Framework in FreemiumCrowdsourcing Platform The FreemiumCrowdsourcing platform replaces purchases in Freemium games with crowdsourcing tasks, which can effectively incentivize player participation using the psychological factor of reward attraction. However, no previous researches focus on quantifying this factor, nor do they make an effort on controlling the answer quality produced by the hybrid platform. We propose a novel online algorithm, IGATA, to allocate crowdsourcing tasks to Freemium game players on the hybrid FreemiumCrowdsourcing platform. In order to maximize the task satisfaction to reduce waste caused by task refusal, while keeping competitive expected profit output, we measure the playersu0027 quality using their ingame attributes, and quantify the task reward attraction as the key factor of allocation with the help of psychological knowledge. Evaluations conducted on real trace data show that IGATA makes a significant improvement in producing total attraction comparing to existing strategies.

Pricing and advertising for rewardbased crowdfunding products in Ecommerce Abstract   This paper studies a rewardbased crowdfunding game wherein the creator first collects money through an Ecrowdfunding platform and then, if successful, invests the raised money to fund promotional activities via online retailing. We derive the creatoru0027s equilibrium decisions and the corresponding payoff and show that they are significantly influenced by the potential demand and the gap between different types of buyer valuations. In particular, with the change in potential market size from low to high, the creator will choose investing none, part or all of the crowdfunded money to improve the advertising level. Meanwhile, when the market size is small, the creator tends to set a high price; when it becomes larger, the creator prefers menu prices or a low price to guarantee the success of the crowdfunding campaign. Comparing two scenarios, one with and one without considering advertising investment, creators may never choose the low price if they cannot raise enough money for advertising; however, that situation can never arise without considering the option of advertising investment. These results provide implications for launching a successful crowdfunding campaign and product promotionadvertising in this Ecommerce era.
