This dataset is a collection of sequences of sets, where each sequence is the time-ordered sets of coauthors of a researcher's publications. Publication data comes from the Microsoft Academic Graph, where the paper is labeled with the "Geology" subject. All sequences contain at least 10 sets, and only sets of size at most 5 are considered. Some basic statistics of this dataset are:

• number of sequences: 57,294
• number of unique elements appearing in sets: 525,348
• number of sets: 1,438,652
• number of unique sets: 1,090,485
