I have a question about kg_final.txt

[1846695868]

Hello, I have some questions about “kg_final.txt”(e.g. In last-fm dataset). In this file, there is a triple composed of head entity, relationship and tail entity. According to what you described in the article, it should be the relationship triple between item and other no item entities. But according to ID, some triples are between two entities, such as (96619, 1,76285) and others are of item itself, such as (5511, 7,5511). I don't quite understand. I hope you can explain it. Thank you.

I also want to know about the real meaning of the another entity in the kg_final.txt ,which is not the item. And the realtion between the two entities can be thought that is also an interaction? I really want to know about it, because I want use my own dataset, but don't have a clear idea to do the preprocess with my own dataset. Hope someone can answer it. If someone is not busy. Thank so much.
