Computing system event error corrective action recommendation

A computer system for diagnosing a computing system error, the system comprising:

• one or more computer processors;
• one or more computer readable storage media;
• computer program instructions to:
• transform the textual description of an event error into feature vectors, wherein the event error is a computing system error;
• analyze the feature vectors;
• generate a recommendation to correct the event error based on analyzing the feature vectors, wherein the recommendation to correct the event error is generated by a contextual bandit model;
• and
• correct the event error, based on the generated recommendation.
