Methods and systems for analyzing communication situation based on emotion information

A non-transitory computer readable medium storing one or more sequences of pattern data for recommending a dialogue sticker group by use of a server that is connected to a database, a first user terminal and a second user terminal through a network and relays an utterance inputted to a messenger between the first user terminal and the second user terminal, the utterance including at least one of a text and an image, wherein execution of the one or more sequences of the pattern data by one or more processors causes the one or more processors to perform the steps of:

• causing the server to analyze utterances, generate utterance data from the analyzed utterances and store the utterance data in the database, the utterance data comprising dialogue situation information, the dialogue situation information including information on dialogue act category, information on emotion category, information on emotion strength of a user, and one or more keywords extracted from the utterances;
• analyzing a set of continuous utterances between the first and second user terminals to determine a dialogue situation between the first and second user terminals, the set of continuous utterances including at least one utterance from the first user terminal and at least one utterance from the second user terminal;
• retrieving, from the utterance data, a portion of the dialog situation information, wherein the portion has a dialog situation similar to the dialog situation between the first and second user terminals;
• determining a relationship between a first user of the first user terminal and a second user of the second user terminal from a set of continuous utterances between the first user terminal and the second user terminal;
• selecting a sticker group based on the retrieved portion of the dialog situation information and the determined relationship, the sticker group including one or more stickers;
• and
• recommending the selected sticker group on a display device of the first user terminal.
