Aspects automatically invoke automated dialog chat bots in response to determining that query text content meets a threshold relevance. A computer processor analyzes different words within text content of a user query input to identify via natural language processing query topics defined by combinations of the words. The processor drives a display device to present an automated dialog chat bot to the user that presents a chat bot series of dialog questions in response to determining that a query topic identified from analyzing the text content meets a threshold relevancy; or searches a database for results that satisfy keywords or query topics of the query content in response to failing to identify a query topic for the query text content, or to determining that an identified query topic does not meet the threshold relevancy.
