I intend to utilize NVivo software for analysis of qualitative data (interviews) for my research. I browsed google scholar, ResearchGate and academia for finding out articles/thesis for review but couldn't find one owing to my inability of appropriate search/key words. Would be grateful, if some articles/theses are recommended with links for reviewing, so that, I can be able to comprehend the description and interpretation of "world cloud" and "word tree" for my research. Thanks.
