Decision tree processing for chatbot dialog flow

A computer implemented method, comprising:

• receiving first dialog input associated with a first topic task in a chatbot session;
• traversing a first decision tree including a first skillset model related to the first topic task to identify at least a first task leaf appropriate to address the first dialog input;
• prior to completion of the first topic task, receiving in the chatbot session, second dialog input associated with a second topic task different from the first topic task;
• transferring to a second decision tree including a second skillset model related to the second topic task, at least one of a property associated with the first task leaf or data associated with the first skillset model;
• traversing the second decision tree to identify at least two second task leaves;
• analyzing at least one of a property or action associated with each of the at least two second task leaves to identify a target leaf of the at least two second task leaves to employ for the second topic task;
• and
• outputting a response to the second dialog input.

An apparatus for generating chatbot sessions in a computing environment, the computing environment comprising one or more computing devices in communication with a chatbot generation system that executes software configured to generate chatbot sessions accessible to the one or more computing devices, a computing device of the one or more computing devices configured to:

• receive first dialog input associated with a first topic task in the chatbot session;
• traverse a first decision tree including a first skillset model related to the first topic task to identify at least a first task leaf appropriate to address the first dialog input;
• prior to completion of the first topic task, receive in the chatbot session, second dialog input associated with a second topic task different from the first topic task;
• transfer to a second decision tree including a second skillset model related to the second topic task, at least one of a property associated with the first task leaf or data associated with the first skillset model;
• traverse the second decision tree to identify at least two second task leaves;
• analyze at least one of a property or action associated with each of the at least two second task leaves to identify a target leaf of the at least two second task leaves to employ for the second topic task;
• and
• output a response to the second dialog input.
