System and method for identifying correlated operator action events based on text analytics of operator actions

An apparatus comprising:

• at least one processing device configured to:
• obtain, from an event log, first text of an alarm associated with an industrial process in a process control system, and process the first text to obtain first key terms;
• obtain, from the event log, second text of an operator response, and process the second text to obtain second key terms;
• filter and segment at least one of the first key terms and the second key terms;
• perform text matching on the first key terms and the second key terms to identify a correlation between the first text and the second text;
• and
• store the first text, the second text, and the correlation between the first text and the second text in a data store.

A non-transitory computer readable medium containing instructions that when executed cause at least one processing device to:

• obtain, from an event log, first text of an alarm associated with an industrial process in a process control system, and process the first text to obtain first key terms;
• obtain, from the event log, second text of an operator response, and process the second text to obtain second key terms;
• filter and segment at least one of the first key terms and the second key terms;
• perform text matching on the first key terms and the second key terms to identify a correlation between the first text and the second text;
• and
• store the first text, the second text, and the correlation between the first text and the second text in a data store.
