Reviews: DiskANN: Fast Accurate Billion-point Nearest Neighbor Search on a Single Node

The writing could be improved, but it's in general understandable. However, citation quality can be improved. In particular, it seems to me that NSG and HNSW are actually using the same pruning rule (which results in approximate relative neighborhood graph). I really like your updated version, which reduces the number hops (and I haven't seen this pruning variant before)! Detailed comments: Abstract and further: base points sounds like a strange term, do you mean domain points? Please, find a more specific-generic citation that describes this phenomena.
