Hello author, sorry about a stupid question. But the Cora dataset has Cora.cites corresponding your cora_edges.csv, and Cora.content's paper index and paper category for your cora_target.csv, so I don't understand the meanning of your cora_features.json . In the beginning, I just think it's an adjacency matrix of all nodes(paper index), however, the content are inconsistent. Such as ,in cora_edges.csv it's as the picture as follw:
and in cora_features.json it's :
So I am confused , and hope for your answer. Thank you very much.
I understand, and I am so stupid, that's the index of bag of words. I am so sorry, thanks anyway.
hello, could you plaese explain cora_feature.json for me? I use this in my own datasets, so i'm not understant the meanning of this format.
@tanjia123456 There is a dictionary composed of the word of all documents, each line of cora_feature.json represents the index of the word (in this document) in the dictionary.
@CindyTing Can I understand it as the feature index corresponding to each node?
@tanjia123456 yeah, I think so.
ok, thank you very much. I will try to make data in this format
Yes it is a sparse matrix in row column index format.
