Question for the information of the dataset

[mgao97]

Thanks for offering a wonderful dataset!

I have two questions need to be solved.

• One is how to construct a dynamic graph based on the dataset.
• The second is about the timestamp information of the edges in this dataset.

Thanks!

Hi. I have the same question. When you see https://github.com/storyandwine/GEARSage-DGraphFin, you can see an edge timestamp is utilized. But it seems like they haven't published the paper yet... Another GAD model that uses DGraphFin is BIAN (https://arxiv.org/pdf/2211.06315.pdf) which will be the top ranker of the leaderboard. However, they haven't published the code base yet. Hope @DGraphXinye will answer soon.

4.2. Experiment Setup
We compared our proposed model with 4 classes of SOTA
models on DGraph. Baseline-Methods include MLP [24],
GCN [8], GraphSage [9], GraphSage-NeighSampler [9],
GAT-NeighSampler [10], GATv2-NeighSampler [26], SIGN
[27]. Baseline models are mainly models that utilize nodes
intrinsic features and its neighbors only.

This means that baseline models use node features only and does not use the timestamp information that is one of the edge features.
