Primary topic identification in text data
An approach for directing a chat agent for an online discussion is provided. A processor retrieves message data from a messaging program. A processor identifies at least one topic present in the message data. A processor, responsive to a determination that the at least one topic is a primary topic, updates the chat agent with the primary topic. A processor modifies message data based on the determined primary topic.

determining a collaborative distance between two or more participants discussing a respective topic for each of the plurality of the topics, wherein the collaborative distance is based on a role assigned to at least one participant in the message data and a frequency of communication between the two or more participants;
analyzing each of the plurality of the topics to determine one or more likelihood probabilities that indicate whether a respective topic is a primary topic or a secondary topic based on the collaborative distances and the respective topic distances for each of the plurality of the topics;
combining each of the plurality of the topic's respective one or more likelihood probabilities to calculate a combined likelihood for each of the plurality of the topics;
comparing each of the plurality of the topic's combined likelihood to a determined threshold value to determine if a respective topic is a primary topic or a secondary topic; and
modifying the message data to designate each of the plurality of the topics as a primary topic or a secondary topic.
