Pseudocode No The paper describes the algorithms and their components but does not provide structured pseudocode or algorithm blocks.
Open Source Code No The paper does not provide any statement or link indicating that the source code for the methodology is openly available.
Open Datasets No The paper states, 'We use a check-in dataset from Twitter to simulate our problem' and that they extracted category information from Foursquare, but it does not provide concrete access information (link, DOI, citation with authors/year) for the processed dataset used in their experiments.
Dataset Splits Yes We randomly remove 20% of non-zero entries from the tensor Xr, which are used as the testing set to evaluate the inferred values, and the remaining 80% are used as the training data.
Hardware Specification Yes All the algorithms are implemented on an Intel Core i5-2400 CPU @ 3.10G HZ with 8 GB RAM.
Software Dependencies No The paper mentions implementation details but does not provide specific software dependencies with version numbers.
Experiment Setup Yes The default values of all parameters used in our experiments are summarized in Table 1. Parameter Default value Time span of historical data h 4 weeks Valid time of tasks φ 1 h Workers reachable radius r 5 km Number of tasks |S| 2000. The parameters (e.g., λ1, λ2 and λ3) of loss function in tensor decomposition are set to 0.01.
