Abstract: Systems and methods for generating a complaint tree data structure based on audio conversation data of a medical visit are provided. Transcript conversation data is generated based on the audio conversation data using one or more automatic speech recognition (ASR) models. A complaint tree section corresponding to a section of the complaint tree data structure is determined based on the transcript conversation data. A plurality of medical entities corresponding to the complaint tree section are extracted from the transcript conversation data, and a relationship between two or more medical entities is determined. A complaint tree data structure is constructed based on the complaint tree section, the plurality of extracted medical entities, and the relationship between the two or more medical entities. Output data comprising an indication of one or more characteristics of the medical visit is generated based on the constructed complaint tree data structure.
