Abstract
In the field of information security, a gap exists in the study of coreference
resolution of entities. A hybrid method is proposed to solve the problem of coreference
resolution in information security. The work consists of two parts: the first extracts all
candidates (including noun phrases, pronouns, entities, and nested phrases) from a given
document and classifies them; the second is coreference resolution of the selected
candidates. In the first part, a method combining rules with a deep learning model
(Dictionary BiLSTM-Attention-CRF, or DBAC) is proposed to extract all candidates in
the text and classify them. In the DBAC model, the domain dictionary matching
mechanism is introduced, and new features of words and their contexts are obtained
according to the domain dictionary. In this way, full use can be made of the entities and
entity-type information contained in the domain dictionary, which can help solve the
recognition problem of both rare and long entities. In the second part, candidates are
divided into pronoun candidates and noun phrase candidates according to the part of
speech, and the coreference resolution of pronoun candidates is solved by making rules
and coreference resolution of noun phrase candidates by machine learning. Finally, a
dataset is created with which to evaluate our methods using information security data.
The experimental results show that the proposed model exhibits better performance than
the other baseline models.
