WebKE: Knowledge Extraction from Semi-structured Web with Pre-trained Markup Language Model |
Abstract | ||
|---|---|---|
ABSTRACTThe World Wide Web contains rich up-to-date information for knowledge graph construction. However, most current relation extraction techniques are designed for free text and thus do not handle well semi-structured web content. In this paper, we propose a novel multi-phase machine reading framework, called WebKE. It processes the web content on different granularity by first detecting areas of interest at DOM tree node level and then extracting relational triples for each area. We also propose HTMLBERT as an encoder the web content. It is a pre-trained markup language model that fully leverages the visual layout information and DOM-tree structure, without the need of hand engineered features. Experimental results show that the proposed approach outperforms state-of- the-art methods by a considerable gain. The source code is available at https://github.com/redreamality/webke. |
