I am considering a specific topic in research paper within data mining field. I just found that my idea is being implemented and published in arXiv in the last month. So far, the published paper matches the flow that I was planning to follow but the author has considered the study with Twitter data. My question is: If I want to do the same experiments but with a different data set like facebook data set will it be considered a new contribution in that field ?
Ps: Row data crawled from Twitter API is way different from row data crawled from Facebook API, and the also different in structure and body.
