Training data identifying a plurality of pairs is received. Each pair identifies one or more separate code snippets known to resolve a respective issue of a plurality of issues. For each pair of the plurality of pairs, a respective issue representation of core content of the respective issue and a linear expression of the one or more separate code snippets in a respective code representation is constructed and a model to correlate the respective code representation as resolving the respective issue representation is trained. The model is queried with a new issue and a selected one of the one or more separate code snippets. The model returns a classification indicating whether the selected one of the one or more separate code snippets is likely to resolve the new issue.

A computer-implemented method, system and computer program product for identifying implicit dependencies between code artifacts. Co-defect association rules between code artifacts are generated, where such co-defect association rules include a prediction of how likely there will be a defect in a code artifact when there is a defect in an associated code artifact. After detecting a defect in a first code artifact, the co-defect association rules are reviewed to identify any code artifacts associated with the first code artifact. If there is a code artifact associated with the first code artifact, and if the probability of the associated code artifact being defected when the first code artifact is defected exceeds a threshold value, then a recommendation is made to the user to review not only the first code artifact that was defected but also its associated code artifact for a potential defect.

Identifying implicit dependencies between code artifacts

An artificial intelligence system monitors and records usage of a set of mobile devices that have been 'paired' or grouped together. The system, over time, accumulates a history of times and locations associated with events that occur with respect to the devices. From this history, the system develops a usage model for the devices. The system, if it detects current usage diverges significantly from an expected usage, performs responsive actions which may include: notifying a user, via a paired device, that the mobile device may be lost or misplaced; command the 'lost' mobile device to enter a reduced power state, to prolong battery life; and/or command the &#x201c;lost&#x201d; device to emit audible and/or visible signals intended to facilitate locating the device. In some embodiments, the system predicts an imminent loss of the device before it becomes lost, based on current usage vs. expected usage embodied in the model.
