Open-CyKG: An Open Cyber Threat Intelligence Knowledge Graph

作者：

Highlights：

• We design an attention-based Open Information Extraction (OIE) model.

• We develop a Named Entity Recognition (NER) model to label cybersecurity terms.

• We present Open-CyKG as an Open Cyber threat intelligence Knowledge Graph.

• We canonicalize the Knowledge Graph (KG) using contextualized word embeddings.

• We demonstrate Information Retrieval (IR) from Open-CyKG with two example queries.
