CGTR: Convolution Graph Topology Representation for Document Ranking

Published: 19 October 2020 Publication History

Abstract

Contextualized neural language models have gained much attention in Information Retrieval (IR) with its ability to achieve better text understanding by capturing contextual structure. However, to achieve better document understanding, it is necessary to involve global structure of a document. In this paper, we take the advantage of Graph Convolutional Networks (GCN) to model global word-relation structure of a document to improve context-aware document ranking. We propose to build a graph for a document to model the global structure. The nodes and edges of the graph are constructed from contextual embeddings. Then we apply graph convolution on the graph to learning a new representation, and this representation covers both contextual and global structure information. The experimental results show that our method outperforms the state-of-the-art contextual language models, which demonstrate that incorporating global structure is useful for improving document ranking and GCN is an effective way to achieve it.

In this paper, we firstly bring Graph Convolutional Networks in the IR task. We propose two deeper representations (feature representations and graph topology representations) from contextualized language model for IR task. We propose to build a graph for a document to model the global structure containing nodes and edges based on contextual embeddings.
