Abstract: A computing device determines similarity between a chat conversation and one or more other chat conversations in public chat channels within computer messaging software and automatically presents the similar public chat channels to a user. A computing device accesses a real-time chat conversation, the chat conversation taking place between a plurality of participants. The computing device analyzes the real-time chat conversation to generate a word density function model modeling at least a part of the real-time chat conversation. The computing device accesses one or more persistent conversations held in a plurality of public chat channels. The computing device determines one or more persistent conversations held in similar public chat channels based upon the generated word density function model. The computing device presents the determined one or more persistent similar public chat channels to a user.
