I want to examine members' comments and postings regarding a specific issue.. Is there any specific software that can help me to get the comments and postings?
The techniques we used to harvest the responses to a ResearchGate question will be of interest.
We simply cut and pasted into Excel the responses to a ResearchGate question.
We fixed spelling and bad grammar.
We manually coded the responses in another column.
We sorted all columns according to code.
We wrote about each code in turn. See our research monograph. The codes we used can be found in the front matter, and the main respondent's names in the back matter, which are both accessible free.
I would have a look into https://import.io/ I have use it for numeric data, not sure about how useful it would be for the comment section but it is surely worth a try!
