[[Github]](https://github.com/LinXueyuanStdio/TFLEX)
[[OpenReview]](https://openreview.net/forum?id=oaGdsgB18L)
[[arXiv]](https://arxiv.org/abs/2205.14307)

- Built over ICEWS and GDELT, which are widely used benchmarks in TKGC.
- First introduced in paper "TFLEX: Temporal Feature-Logic Embedding Framework for Complex Reasoning over Temporal Knowledge Graph"
- Please refer to the original paper for more details.
