那设计的路径不用开始和结尾都一样吧,比如Author开始,结尾也要Author??我看好多文献都是这样子的,期待您的回复。

不是必要的。元路径的设计是有具体的语义的。比如在科研合作网络中, Author-Paper-Author 的元路径意味着起点和终点的 Author 之间存在合作关系,Author-Venue-Author 的元路径意味着起点和终点的 Author 之间存在共同参会的关系。您看到的文献中应该只是恰好使用/设计了这些首尾类型一样的元路径,并不是说元路径的设计一定要求起始节点类型和终点类型要一样。

没有特别要求,全靠经验和先验知识。设计的路径如果make sense并且能work即可
