Reproducibility Variable Result LLM Response
Research Type Theoretical We show the expressive abilities of our framework and study the data complexity of CQE for (unions of) conjunctive queries when ontologies are specified in the Description Logic DL-Lite R. Interestingly, while we show that the problem is in general intractable, we prove tractability for the case of acyclic epistemic dependencies by providing a suitable query rewriting algorithm. The latter result paves the way towards the implementation and practical application of this new approach to CQE.

Open Source Code No The paper does not contain an explicit statement about releasing source code for the described methodology or a direct link to a code repository.
Open Datasets No The paper is theoretical in nature and does not conduct experiments on specific, publicly available datasets. It uses abstract ABoxes and TBoxes for theoretical definitions and examples rather than empirical data.
Dataset Splits No The paper is theoretical and does not conduct empirical experiments, therefore, it does not provide dataset split information for training, validation, or testing.
Hardware Specification No The paper does not provide any specific details about the hardware (e.g., GPU/CPU models, memory) used for running experiments or computations.
Software Dependencies No The paper does not list specific software dependencies with version numbers.
Experiment Setup No The paper is theoretical and does not involve an experimental setup with hyperparameters, optimizer settings, or system-level training configurations.
