I have an algorithm in community detection in a complex network but I need a small, medium and large size datasets with ground truth communities. I have found two, named Zarchy karate club and U.S. football team but I need more for evaluation.
You can check the SNAP dataset. However, note that using ground truth community structures has been criticized in the literature, see (Lee & Cunningham 2017), (Dao et al. 2017), (Chakraborty et al. 2018)
