Xavier Amatriain, Neal Lathia, Josep M. Pujol, Haewoon Kwak, Nuria Oliver
2009 Proceedings of the 32nd international ACM SIGIR conference on Research and development in information retrieval - SIGIR '09  
In this work, we present a novel method for recommending items to users based on expert opinions.  ...  Our method is a variation of traditional collaborative filtering: rather than applying a nearest neighbor algorithm to the user-rating data, predictions are computed using a set of expert neighbors from  ...  INTRODUCTION Collaborative filtering (CF) is the current mainstream approach used to build web-based recommender systems [1] .  ...

Expert Stock Picker: The Wisdom of (Experts in) Crowds

Shawndra Hill, Noah Ready-Campbell
2011 International Journal of Electronic Commerce  
Our contribution is that we provide a method based on a genetic algorithm (GA) to learn the appropriate contributions of independent users through the use of observed past individual performance.  ...  The phrase "the wisdom of crowds" suggests that good verdicts can be achieved by averaging the opinions and insights of large, diverse groups of people who possess varied types of information.  ...  approach, will outperform using the entire crowd to vote-we used a GA to identify an investment strategy relying on a blend of expert-based wisdom and crowd-based wisdom.  ...

The wisdom of polarized crowds

Feng Shi, Misha Teplitskiy, Eamon Duede, James A. Evans
2019 Nature Human Behaviour  
Here, we explore the effect of ideological composition on team performance by analysing millions of edits to Wikipedia's political, social issues and science articles.  ...  Our analysis reveals that polarized teams consisting of a balanced set of ideologically diverse editors produce articles of a higher quality than homogeneous teams.  ...  We measured the quality of Wikipedia articles algorithmically using a prominent approach that draws on features derived from article content alone and not information about editors or their collaboration  ...

Wikipedia and the Wisdom of Crowds: A Student Project

Greg Barnhisel, Marcia Rapchak
2014 Communications in Information Literacy  
Students in a senior English class examined the question of whether the 'wisdom of experts' or 'the wisdom of crowds' is more reliable and useful in a writing course by engaging in a parallel Wikipedia  ...  what they learned; simultaneously, the class as a whole collaborated on a Wikipedia entry about a local landmark's controversy.  ...  But like Student 2, her opinion changed: During class, I answered the question, "What is more reliable, the wisdom of experts, or the wisdom of crowds?"  ...

Social Learning and the Accuracy-Risk Trade-off in the Wisdom of the Crowd [article]

Dhaval Adjodah, Yan Leng, Shi Kai Chong, P. M. Krafft, Esteban Moro, Alex Pentland
2020 arXiv   pre-print
To answer this question, we conducted a large online Wisdom of the Crowd study where participants predicted the prices of real financial assets (e.g. S&P 500).  ...  We also observe that social learning leads to superior accuracy during one of our rounds that occurred during the high market uncertainty of the Brexit vote.  ...  Higher relative errors in round 2 are an artifact of the fact that a few dollars' error on the lower price of WTI Oil seems like a higher error compared to same absolute error on the higher prices of the  ...
