# Knowledge Graph Extraction for Cyber incidents
This model has been finetuned with SecureBERT (https://arxiv.org/abs/2204.02685)
on the CASIE dataset (https://ieeexplore.ieee.org/document/9776031). We have implemented the approach described in the CASIE paper.
# Model Description
The following description is taken from the CASIE paper:
- An **event nugget** is a word or phrase that most clearly expresses the event occurrence. These differ from event triggers in that they can be multi-word phrases.
- An **event argument** is an event participant or property value. They can be taggable entities involved in the event, such as person or organization, or attributes that specify important information, such as time or amount.
- A **role** is a semantic relation between an event nugget and an argument. Each event type specifies the roles it can have and constraints on the arguments that can fill them.
- A **realis** value specifies whether or not an event occurred and can be one of the three values: Actual (event actually happened), Other (failed event, future event), or Generic (an undetermined/non-specific event, such as referring to the concept of phishing attacks).
