Cognitive determination of message suitability

A computer-implemented method within a computer hardware system including an image caption generator, comprising:

• receiving, by the computer hardware system, an image and a message corresponding to the image;
• recognizing, by the image caption generator, an object within the image;
• generating, by the image caption generator, a caption describing the object;
• determining, by a classifier model, a topic based upon the caption and the message corresponding to the image;
• classifying the topic;
• and
• generating, based upon the classifying that the topic is unsuitable for sending, an alert message that the message corresponding to the message is unsuitable for sending.

A computer hardware system including an image caption generator, comprising:

• a hardware processor programmed to initiate the following executable operations:
• receiving an image and a message corresponding to the image;
• recognizing, by the image caption generator, an object within the image;
• generating, by the image caption generator, a caption describing the object;
• determining, by a classifier model, a topic based upon the caption and the message corresponding to the image;
• classifying the topic;
• and
• generating, based upon the classifying that the topic is unsuitable for sending, an alert message that the message corresponding to the message is unsuitable for sending.

A computer program product, comprising:

• a computer hardware storage device having stored therein program code,
• the program code, which when executed by a computer hardware system including an image caption generator, causes the computer hardware system to perform:
• receiving an image and a message corresponding to the image;
• recognizing, by the image caption generator, an object within the image;
• generating, by the image caption generator, a caption describing the object;
• determining, by a classifier model, a topic based upon the caption and the message corresponding to the image;
• classifying the topic;
• and
• generating, based upon the classifying that the topic is unsuitable for sending, an alert message that the message corresponding to the message is unsuitable for sending.
