Crowdsourcing Approaches for Smart City Open Data Management
Post on 28-May-2015
DESCRIPTIONA wide-scale bottom-up approach to the creation and management of open data has been demonstrated by projects like Freebase, Wikipedia, and DBpedia. This talk explores how to involving a wide community of users in collaborative management of open data activities within a Smart City. The talk discusses how crowdsourcing techniques can be applied within a Smart City context using crowdsourcing and human computation platforms such as Amazon Mechanical Turk, Mobile Works, and Crowd Flower.

Introduction to Crowdsourcing Coordinating a crowd (a large group of workers)to domicro-work (small tasks) that solves problems (thatcomputers or a single user cant) A collection of mechanisms and associatedmethodologies for scaling and directingcrowd activities to achieve goals Related Areas Collective Intelligence Social Computing Human Computation Data MiningA.

Spatial Crowdsourcing Spatial Crowdsoucring requires a person to travel to alocation to preform a spatial task Helps non-local requesters through workers in targeted spatiallocality Used for data collection, package routing, citizen actuation Usually based on mobile applications Closely related to social sensing, participatory sensing, etc. Early example Ardavark social search 18.

Money ($$), Glory (reputation/prestige), Love (altruism, socialize,enjoyment), Unintended by-product (e.g. re-Captcha, captured inworkflow), Self-serving resources (e.g. Wikipedia, product/customerdata), Part of their job description Determine pay and time for each task Marketplace: Delicate balance (Money does not improve quality but can increaseparticipation) Internal Hierarchy: Engineering opportunities for recognition: Performance review, prizes fortop contributors, badges, leaderboards, etc.3 What is being done? Creation Tasks: Create/Generate/Find/Improve/ Edit / Fix Decision (Vote) Tasks: Accept/Reject, Thumbs up / Down, Vote4 How is it being done? Identify the workflow: Integrate in workflow (rating algorithm) Identify the platform (Internal/Community/Public) Identify the Algorithm (Data quality, Image recognition, etc.) 28.
