Deco implements a novel push-pull hybrid execution model in order to support a flexible data model and a precise query semantics, while coping with the combination of latency, monetary cost, and uncertainty of crowdsourcing. We demonstrate Deco using two crowdsourcing platforms: Amazon Mechanical Turk and an in-house platform, to show how Deco provides a convenient means of collecting and querying crowdsourced data.\n          <\/jats:p>","DOI":"10.14778\/2367502.2367555","type":"journal-article","created":{"date-parts":[[2014,6,24]],"date-time":"2014-06-24T12:17:57Z","timestamp":1403612277000},"page":"1990-1993","source":"Crossref","is-referenced-by-count":51,"title":["Deco"],"prefix":"10.14778","volume":"5","author":[{"given":"Hyunjung","family":"Park","sequence":"first","affiliation":[{"name":"Stanford University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hector","family":"Garcia-Molina","sequence":"additional","affiliation":[{"name":"Stanford University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Richard","family":"Pang","sequence":"additional","affiliation":[{"name":"Stanford University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Neoklis","family":"Polyzotis","sequence":"additional","affiliation":[{"name":"UC Santa Cruz"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aditya","family":"Parameswaran","sequence":"additional","affiliation":[{"name":"Stanford University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jennifer","family":"Widom","sequence":"additional","affiliation":[{"name":"Stanford University"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"320","published-online":{"date-parts":[[2012,8]]},"reference":[{"key":"e_1_2_1_1_1","unstructured":"Mechanical Turk. http:\/\/mturk.com.
