FTM: A Frame-level Timeline Modeling Method for Temporal Graph Representation Learning

1 code implementation23 Feb 2023 Bowen Cao, Qichen Ye, Weiyuan Xu, Yuexian Zou

Existing neighborhood aggregation strategies fail to capture either the short-term features or the long-term features of temporal graph attributes, leading to unsatisfactory model performance and even poor robustness and domain generality of the representation learning method.

FiTs: Fine-grained Two-stage Training for Knowledge-aware Question Answering

1 code implementation23 Feb 2023 Qichen Ye, Bowen Cao, Nuo Chen, Weiyuan Xu, Yuexian Zou

Despite the promising result of recent KAQA systems which tend to integrate linguistic knowledge from pre-trained language models (PLM) and factual knowledge from knowledge graphs (KG) to answer complex questions, a bottleneck exists in effectively fusing the representations from PLMs and KGs because of (i) the semantic and distributional gaps between them, and (ii) the difficulties in joint reasoning over the provided knowledge from both modalities.
