15. JingTao Yao 15 A Ten-year Review of Granular Computing Research Trends and Interaction Scientific growth is a diffusion process (Crane 1972: Invisible colleges) In the areas where researchers are aware of each other's existence, the curve of cumulative growth of publications and of authors entering the field follows a logistic pattern. –More new authors –Interacting with other domain –More publications

17. JingTao Yao 17 A Ten-year Review of Granular Computing Granular Computing Trend More linear like growth –Growth slowly –Less new authors (? did not check) Interaction –Fuzzy (6/15) –Rough (7/15) –Remaining (3/15) Hidden Fuzzy (2/3) Hidden Rough (1/3) –Others ? (interval computing, concept lattice, …) Runge-Kutta

18. JingTao Yao 18 A Ten-year Review of Granular Computing Concluding Remarks Use standard term in Title, Abstract, and Keywords. (to be known) –Granular Computing, GrC –Searchable from bibliographic databases GrC researc grows healthily but still have long way to go - > need more interaction Interact with other domain –GrC shares many thoughts with other domain especially in philosophical level –Come (Invite people from other domains, WI-IAT-BIBM) –Go (Attend, submit GrC papers to other conferences, journals) New blood
