Summarization for survey open end questions
Hi   I’m working in HR and would like to summarize key topics  in employee questionnaire.Let’s say there is a question " what effort is required to improve onboarding experience for new hire?" . There are  6000 replies and each answers  ranges  from 3 words to 200 words.   Because this is not a single document but multiple documents, I consolidated all comments into single document and applied various summarization model(T5, Bart…). However,  the summary result does not look correct.  Can I ask if there is a model/method which reads multiple documents and provide a summary or topic?Thanks
