Thanks for reply, sorry i am bit late in responding. My answers in-line
1)Do you have a labelled data set of patient chat conversation against their depression level? - No, we don’t have any chat history of patient as this is new project so we don’t have anything in place. We are suppose to design interactive chat pod which will converse with patient and predict, though we are planning to train corpus based on the data that we will collect from internet or other sources
2)And how large it is ? - NA
3)Approx how long is each conversation(no. of words) - NA
4)Are you considering features other than patient’s chat conversation eg. time of conversation etc? - NA
Note: Company want us to come up with this utility which will converse with patient and predict mood, previously a small question and answer system is there, which ask few specific questions to patient and based on their response it define mood of patient.
