Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATION
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 13:
14. An interactive dialog system, comprising:
a hardware processor; and
a memory that stores a computer program, which, when Executed by the Hardware processor, causes the hardware processor to:
recursively determine a set of sector points that equally divide a distance between a current topic and a target topic;
determine, after identifying the current topic and the target topic, a path through a vector space, from the current topic to the target topic, that includes a set of bridging topics based on topic words that are close to the sector points, where each bridging topic in the path is d ermined based on a semantic similarity score defined by cosine similarity between word-vectors in a vector space, and is within a threshold distance in the vector space from a previous topic and a subsequent topic;
conduct an interactive conversation with a user, including accepting inputs front the user via a user interface and providing responses to the user via the user interface, introducing each topic the path until the target topic has been reached;
analyze, using natural language processing (NLP), from the user and responses during the interactive conversation to refine the set of bridging topics base contextual relevance; and
record at least one predetermined piece of information relating to the inputs from the user and the responses during the interactive conversation for the target topic.
