Witkeys are a thriving type of web-based knowledge sharing market in China, supporting a form of crowdsourcing. In a Witkey site, users offer a small award for a solution to a task, and other users compete to have their solution selected. In this paper, we examine the behavior of users on one of the biggest Witkey websites in China, Taskcn.com. On Taskcn, we observed several characteristics in users' activity over time. Most users become inactive after only a few submissions. Others keep… 

Making Task Recommendations in Crowdsourcing Contests

A methodology to develop a system that can recommend tasks to solvers who wish to participate in crowdsourcing contests based on the probability of the solver winning an open task is proposed and a multinomial logit model has been developed to estimate these winning probabilities.

Know When to Run: Recommendations in Crowdsourcing Contests

A framework to recommend tasks to solvers who wish to participate in crowdsourcing contests and it is shown that deploying such a system should benefit not only the solvers, but also the seekers and the platform itself.

Whether the sponsor can obtain a positive expected payoff are determined by the type of tasks, while the complex tasks with a strong learning effect is more suitable to selective crowdsourcing.

Sponsored Tasks and Solver Participation in Crowdsourcing Contests

Crowdsourcing platforms provide a venue where firms looking for solutions (seekers) and individuals who can provide solutions (solvers) interact with each other. As crowdsourcing contest platforms

Individual and Collective User Behavior in Crowdsourcing Services

Analysis of profiles of user behavior in selecting tasks and the resulting profits in online crowdsourcing services finds evidence of a market segmentation where individual workers tend to direct their effort to tasks from specific ranges of rewards, reflecting their level of skill.

Understanding the Role of Goals in Competitive Crowdsourcing Project Selection

This paper explores two factors that potentially impact crowdsourcing task selection, namely perceived ability and perceived competition, and further explores a moderating effect of goal orientation on task participation intention.

Designing Incentive for Cooperative Problem Solving in Crowdsourcing

The goal of this thesis is to design incentives for workers in crowdsourcingbased cooperative task solving, with the aim of improving the quality of task solution. Crowdsourcing is an online,

Crowdsourcing and All-Pay

A model in which users select among, and subsequently compete in, a collection of contests offering various rewards is presented and it is found that rewards yield logarithmically diminishing returns with respect to participation levels.

This study analyzes the Java Forum, a large online help-seeking community, using social network analysis methods and tests a set of network-based ranking algorithms on this large size social network in order to identify users with high expertise.

A content-driven reputation system for the wikipedia

The results show that the notion of reputation has good predictive value: changes performed by low-reputation authors have a significantly larger than average probability of having poor quality, as judged by human observers, and of being later undone, as measured by the algorithms.

Predictors of answer quality in online Q&A sites

It is found that a Q&A site's community of users contributes to its success, and it was typically higher in Google Answers (a fee-based site) than in the free sites the authors studied, and paying more money for an answer led to better outcomes.

A model of tagging systems, specifically in the context of web-based systems, is offered to help illustrate the possible benefits of these tools and a simple taxonomy of incentives and contribution models is provided to inform potential evaluative frameworks.

Usage patterns of collaborative tagging systems

A dynamic model of collaborative tagging is presented that predicts regularities in user activity, tag frequencies, kinds of tags used, bursts of popularity in bookmarking and a remarkable stability in the relative proportions of tags within a given URL.
