One of the significant challenges in this process is how to determine the parameters for task publishing. Still some technique applied constraint solving to select the optimal tasks parameters so that the total cost of completing all tasks is minimized. However, experimental results show that computational complexity makes these tools unsuitable for solving large-scale problems because of its excessive execution time. Taking into account the real-time requirements of crowdsourcing, this study uses a heuristic algorithm with four heuristic strategies to solve the problem in order to reduce execution time. The experiment results also show that the proposed heuristic strategies produce good quality approximate solutions in an acceptable timeframe.<\/jats:p>","DOI":"10.1142\/s0218194019500268","type":"journal-article","created":{"date-parts":[[2019,6,25]],"date-time":"2019-06-25T13:23:22Z","timestamp":1561469002000},"page":"763-790","source":"Crossref","is-referenced-by-count":2,"title":["A Novel Approach to Publishing Tasks for Collaboratively Crowdsourcing Workflows"],"prefix":"10.1142","volume":"29","author":[{"given":"Wenjun","family":"Tang","sequence":"first","affiliation":[{"name":"College of Information Science and Technology, Dalian Maritime University, Dalian 116026, P.\u00a0R.\u00a0China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rong","family":"Chen","sequence":"additional","affiliation":[{"name":"College of Information Science and Technology, Dalian Maritime University, Dalian 116026, P.\u00a0R.\u00a0China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shikai","family":"Guo","sequence":"additional","affiliation":[{"name":"College of Information Science and Technology, Dalian Maritime University, Dalian 116026, P.\u00a0R.\u00a0China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2019,6,25]]},"reference":[{"key":"S0218194019500268BIB003","first-page":"1801","volume-title":"Proc. 24th Annual ACM Symp.
