In an example computer-implemented method, a dataset and a query including an expression to be matched to the dataset is received via a processor. A false positive rate (FPR) and a false negative rate (FNR) is calculated via the processor for each possible value assignment of a plurality of possible value assignments in response to detecting a missing value in the dataset. A value assignment is selected, via the processor, from the plurality of possible value assignments based on the FPR and the FNR. A response to the query is generated via the processor based on the selected value assignment.

Generating responses to queries based on selected value assignments

The present invention is directed to a method for diagnosing faults in a software system, according to which, predictions of the probability of each software component of the software system to be faulty are obtained from a diagnoser, and the probability predictions are input to a fault diagnosis software module, executed by the diagnoser.

Data-augmented software diagnosis method and a diagnoser therefor

An artificial intelligence based method for improving a software testing process, according to which upon finding a bug, a set of candidate diagnoses is proposed to the tester, based on a Model-Based Diagnosis (MBD) process. A planning process is used for automatically suggesting further test steps to be performed by the tester, to identify the correct diagnosis for the developer in the form of faulty software component that caused the bug, while minimizing the tests steps performed by the tester. Additional information is provided to the MBD process, based on the outputs of the further test steps, thereby pruning incorrect candidate diagnoses. These steps are iteratively repeated while in each time, minimizing the set of candidate diagnoses, until a single diagnosis remains in the set.
