However, most of these approaches are still mainly using manual methods [1]. Ontology enrichment is a fairly standard approach in domain ontology construction, in which semi-automated methods and automated methods of ontology learning from a derived ontology. Relation extraction is one of the ways for ontology enrichment. Relation extraction techniques include law-based techniques, machine learning-based techniques with three typical methods: supervised learning, semi-supervised learning, and unsupervised learning. This paper proposes a word + character embedding-based relation extraction frame for the Vietnamese domain ontology of natural resources and environment. The model's effect was demonstrated by experiments in the domain of natural resources and the envi-ronment and achieving promising results. date: 2020-12-16 type: Conference or Workshop Item type: NonPeerReviewed format: application/pdf language: en identifier: https://eprints.uet.vnu.edu.vn/eprints/id/eprint/4175/1/20_ICISA2020_program.pdf identifier: Nguyen, Ngoc Vu and Tran, Mai Vu and Nguyen, Hai Chau and Ha, Quang Thuy (2020) A Word + Character Embedding based Relation Extraction Frame for Domain Ontology of Natural Resources and Environment.
