Pseudocode Yes Algorithm 1 Multi-Winner Contests Mechanism
Open Source Code No The paper does not provide an explicit statement or link to the open-source code for the described methodology.
Open Datasets Yes We used four publicly available datasets: Twitter (Hodas and Lerman 2014), Flickr (Cha, Mislove, and Gummadi 2009), Flixster (Goyal, Bonchi, and Lakshmanan 2011), and Digg (Hogg and Lerman 2012).
Dataset Splits No The paper describes using datasets for simulation and analysis but does not specify training, validation, or test dataset splits (e.g., percentages or counts for each split).
Hardware Specification Yes We ran all the experiments on the same 3.7GHz 6-core Linux machine with 32GB RAM.
Software Dependencies No The paper mentions learning algorithms and models but does not provide specific software dependencies with version numbers (e.g., programming languages, libraries, or frameworks with their versions).
Experiment Setup Yes We set λ = 0.5 as it was standard in many geometric reward mechanisms. In practice, a stakeholder usually sets ϕ 1 to make profits, but ϕ should be as close to 1 as possible to encourage players to participate. We let ϕ = 1. To encourage players to join, we set µ = 0.9, and φ = ϕ µ = 0.1. Note that η λ/2 = 0.25, we set η = 0.25. For each group of players in each dataset, we varied the noise factors from 0 to 1 with an increment of 0.05. For each result (i.e., a data point) obtained, we ran the respective experiment 20 times.
