Reproducibility Variable Result LLM Response
Research Type Experimental We have implemented our approach in a prototype system. The evaluation over a set of benchmarks shows encouraging results. Finally, we develop a prototype and conduct experiments on a set of benchmarks. The results confirm that the our approach is scalable for query answering with GNTGDs.

Pseudocode No The paper contains theoretical discussions, lemmas, and theorems, but no pseudocode or clearly labeled algorithm blocks.
Open Source Code Yes We implemented a prototype system in Python for query answering with GNTGDs2. To the best of our knowledge, this is the first system with such functionality. The code and data to reproduce the experiments are in the online appendix. 2Code and datasets. https://github.com/sysulic/GNTGDs
Open Datasets Yes We considered three GNTGDs: LUBM3, Geo Concepts4, and Vicodi5 and two (multi-)linear TGDs: DEEP100(-200)6 as benchmarks... 3LUBM. http://swat.cse.lehigh.edu/projects/lubm/ 4Geo Concepts. http://www.kr.tuwien.ac.at/research/projects/myits/ 5Vicodi. http://www.vicodi.org 6DEEP-100(-200). https://github.com/dbunibas/chasebench
Dataset Splits No The paper provides dataset sizes but does not specify training, validation, or test splits. For example, Table 1 shows |D| (database size) values like 100, 122, 165, 1000, but no explicit split percentages or counts for training/validation/test sets.
Hardware Specification Yes All experiments run in 64-bit Linux on a machine with 2.10GHz Intel Xeon and 128G 1333 MHz memory.
Software Dependencies Yes We use the ASP solver clingo-4.4.0.
Experiment Setup No The paper describes the overall system (MGIF, MGCF modes) and the benchmarks used but does not provide specific details such as hyperparameters (e.g., learning rates, batch sizes, number of epochs) or other system-level training settings.
