Identifying and rewarding truthful workers are key to the sustainability of crowdsourcing platforms. In this paper, we present a clustering based reward mechanism that rewards workers based on their truthfulness while accommodating differences in workers’ preferences. Experimental results show that the proposed approach can effectively discover subcrowds under various conditions; and truthful w...

Palliative care is still a topic under discussion in the Iranian healthcare system, and cancer patients require palliative care. Moreover, nursing ethics has an important role in caring for these patients. The purpose of this study was to identify the perception of Iranian nurses regarding ethics-based palliative care in cancer patients. This study was done with a qualitative approach and by us...

This manuscript presents an alternative implementation of the truthful-in-expectation (TIE) mechanism of Dughmi, Roughgarden and Yan [2] for combinatorial auctions. Recall that in a combinatorial auction, m goods get allocated to n bidders. Each bidder i has a private valuation vi that describes its value vi(S) for each subset S of goods. The social welfare of an allocation is the sum of the bi...

Recent work has demonstrated the viability of using crowdsourcing as a tool for evaluating truthfulness public statements. Under certain conditions such as: (1) having balanced set workers with different backgrounds and cognitive abilities; (2) an adequate mechanisms to control quality collected data; (3) coarse grained assessment scale, crowd can provide reliable identification fake news. Howe...

In this study, we examine the feasibility of reviewing research publications through crowdsourcing. We propose a post-publication review model where the research materials are posted online for the crowd volunteers to review. One such platform, named PuGLi, is prepared and the data collected from it is analyzed. The analysis raises some interesting questions related to the challenges of attract...

INTRODUCTION Publication is the final affirmation of scholarly accomplishment. Academic advancement, “publish or perish,” as well as prestige, are other important driving forces. There are many financial benefits (direct and indirect) in publishing such as promotion and further research funding. Many of these forces can lead to ethical lapses. All authors have several important ethical obligati...

Checking the truth value of political statements is difficult. Fact checking computationally has therefore not been very successful. An alternative to checking the truth value of a statement is to not consider the facts that are stated, but the way the statement is expressed. Using linguistic features from seven computational linguistic algorithms, we investigated whether truth-false statements...

This chapter is concerned with how teenage boys and girls present themselves through online social media such as Facebook, Twitter, blogs, and chat forums. Based on research conducted mostly in the United States, it describes and considers the implications of social media use, profile construction, visual and textual self-presentation, profile visibility, truthfulness, and other facets of teens...

Personal genomics offers a complex form of uncertainty in which a person’s data are largely stable, but the interpretation and implications continue to evolve with the emergence of new research. Another domain, in which there is uncertainty about the supporting evidence and truthfulness of a claim, is social networks. We propose that a similar method can be used to communicate uncertainty in th...
