I found that when two authors share the same name, they are incorrectly grouped together as the same author.

In the data processing, I found that if two authors have the same name, for example, Yang, Xia (University A) and Yang, Xia (University B), they are grouped as the same author, even though they are from different universities. In this case, different authors with the same name are actually distinct individuals. Could this be considered a significant issue for the project?

Here is an example dataset (These authors are different individuals but are incorrectly grouped as the same author):

Once we have our subset of possible similar entries, we match the existing info of row 1 against the subset. The entry only needs to match one extra piece of information - either address, email, or middle name. If it matches we assume it is the same person, and change the groupID numbers to reflect this.
