Abstract:

In the field of threat intelligence entity extraction, due to the complex structure of network data sources, more irrelevant information, and the strong professional and fuzzy classification of threat intelligence entities, the efficiency of traditional entity recognition methods for threat intelligence mining is not high. To solve this problem, this paper put forward a kind of MRC pointer annotation model(TIMRC) by transforming entity recognition into machine reading comprehension. The model could find the corresponding beginning and end index for each entity problem. Based on this, a threat intelligence entity identification(TIEI) method was further constructed. Experiments on 978 security articles show that TIEI method is effective and efficient in entity mining.

Key words: threat intelligence, entity recognition, machine reading comprehension
