Managing the Quality of Large-Scale Crowdsourcing
Crowdsourcing can be used to obtain relevance judgments needed for the evaluation of information retrieval systems. However, the quality of crowdsourced relevance judgments may be questionable; a substantial amount of workers appear to spam HITs in order to maximize their hourly wages, and workers may know less than expert annotators about the topic being queried. The task for the TREC 2011 Cro...
متن کاملCrowdsourcing for Large-Scale Pervasive Sensing
Crowdsourcing, or the act of outsourcing a task to the crowd, has the potential to revolutionize information collection and processing systems by enabling in-depth, large-scale, cost-effective information gathering, and more accurate techniques for information extraction from data. Crowdsourcing provides a powerful mechanism for creating data about the physical world, particularly through the u...
متن کاملEvolutionary Crowdsourcing Approach for Quality Control
Crowdsourcing is widely used for solving simple tasks (e.g. tagging images) and recently, some researchers [9][10] propose new crowdsourcing models to handle complex tasks (e.g. articling writing). In both type of crowdsourcing models (for simple and complex tasks), voting is a technique that is widely used for quality control [9]. However, we argue that voting is actually a technique that sele...
متن کاملCrowdsourcing Quality Control for Item Ordering Tasks
One of the biggest challenges in crowdsourcing is quality control which is to expect high quality results from crowd workers who are not necessarily very capable nor motivated. In this paper, we consider item ordering questions, where workers are asked to arrange multiple items in the correct order. We propose a probabilistic generative model of crowd answers by extending a distance-based order...
متن کاملA Knowledge-Based Approach to Raster-Vector Conversion of Large Scale Topographic Maps
Paper-based raster maps are primarily for human consumption, and their interpretation always requires some level of human expertese. Todays computer services in geoinformatics usually require vectorized topographic maps. The usual method of the conversion has been an error-prone, manual process. In this article, the possibilities, methods and difficulties of the conversion are discussed. The re...
