Each event type in a business process is represented by a node in a process discovery graph. Semantic clustering merges nodes based on a commonality between them. As a result, a graphical user interface (GUI) may be presented that shows fewer nodes. This process may be repeated, using different commonalities at each level. A user may select a node to zoom in, showing the constituent nodes. The frequency of an event or its other attribute values may be compared to a predetermined threshold to determine if the event is a blocking event. The GUI may indicate that the node for an event is a blocking event. When the node for the event is merged with other nodes using semantic clustering, the blocking status of the node is transferred to the merged node. After zooming in on the blocking event, the GUI allows the user to select the blocking event to cause display of a recommendation.

A computer-implemented method can receive a vulnerability report for a software. The vulnerability report specifies a vulnerable library used by the software and a path of the vulnerable library within the software.

Related systems and software for implementing the method are also disclosed.

In an example embodiment, a mechanism is provided to allow an LLM to generate multiple text blocks in which different grammars are strictly enforced with a single invocation.

This data is then merged into the active data, after processing and postprocessing. The result of these postprocessing operations is then stored in the active data portion of the local ingestion table file.
