I am from a social science field. As a part of my dissertation I have published a paper on my topic in a journal with good standing. In that paper, I propose a framework to analyze an issue and related topics. This got published, even received several citations in the last year.
Today, I came across another work, released one year before my work using a very similar framework with a massively different interpretation and application.
I will try my best explain the similarities as an example.
We both look at socioeconomic standings of a populations (in different countries, with different focuses) but we use the same two parameters (let's say positive / negative and happiness / unhappiness) and combine them, in slightly different manners. I merge these parameters to create four categories and analyze these categories depending on data - collected by myself. The other one quantifies these categories on their data - collected by themselves, through topics derived from the literature.
So our way to analyze, at least in the beginning, are similar, however, our focus (as in what aspect and which populations we are looking at), findings, cases, utilizations are incredibly different.
Interestingly, we only share one source throughout all this. However at the end of the day, we are both focused on positive / negative / happiness / unhappiness combination. There are more differences involved by the way. Coding scheme, focus within the field, the cases we compare, quantification, etc.
What do I do? Should I even do something about this or yes, two people can develop similar frameworks from different sources and utilize it as their own. They do sound same, which is a worry for me.
