Abstract: Provided is a process, including: obtaining a plurality of software-issue reports; obtaining a pull request; forming a software-issue graph having a plurality of nodes corresponding to the software-issue reports and a plurality of edges indicating relationships between the software-issue reports; determining that the pull request addresses a given software-issue report; selecting a subset of nodes in the software-issue graph addressed by the pull request; and designating the pull request as being associated with the plurality of software-issue reports corresponding to the selected subset of nodes.

Abstract: Provided is a process of inferring which software-issue reports are addressed by a code-change submission, the process including: obtaining a plurality of software-issue reports; obtaining a current code-change submitted to a repository of source code of a software application; selecting a subset of the software-issue reports by inferring which of the software-issue reports describe an issue addressed by the current code-change; and storing in memory an association between the subset of the software-issue reports and the current code-change.

Abstract: Provided is a process, including: obtaining a workflow execution log; training a first supervised machine learning model to infer roles of users in the workflows based on the workflow execution log; obtaining a given instance of a given workflow; inferring, with the first supervised machine learning model, at least one role of at least one user in the given instance of the given workflow; and causing at least part of the given instance of the given workflow to be presented to the at least one user in a user interface.

Abstract: Provided is a process, including: obtaining a plurality of software-issue reports; obtaining a pull request; forming a software-issue graph having a plurality of nodes corresponding to the software-issue reports and a plurality of edges indicating relationships between the software-issue reports; determining that the pull request addresses a given software-issue report; selecting a subset of nodes in the software-issue graph addressed by the pull request; and designating the pull request as being associated with the plurality of software-issue reports corresponding to the selected subset of nodes.

Abstract: Provided is a process of estimating time to address software-issue reports describing software bugs or feature requests in software project management computer systems based on historical performance in addressing previous software-issue reports, the process including: obtaining the workflow instance records; constructing a time-estimation model based on correlation between features of the workflow instance records and durations of time before or during execution of some or all of respective workflow instances; obtaining a workflow instance that is not completed; estimating a duration of time for the task with the time-estimation model.
