In this talk, I will share with the audience my research experiences on a range of NLP tasks, including text matching, text mining, and text generation. I will demonstrate that the graph is a natural way to capture the connections between different text objects, such as words, entities, sentences, and documents. By combining graph-structured representations of text objects at various granularities with Graph Neural Networks (GNNs), significant benefits can be brought to various NLP tasks. Finally, I will share my experience in deploying our algorithms in industry applications, such as Tencent QQ Browser, Mobile QQ and WeChat, for hot event discovery, query and document understanding, as well as news feeds recommendation.
