ENTITY AND RELATIONSHIP JOINT EXTRACTION METHOD ORIENTED TO SOFTWARE BUG KNOWLEDGE

摘要

Disclosed are an entity and relationship joint extraction method oriented to software bug knowledge, the method comprising: collecting text data of an open source bug library, and preprocessing the text data to obtain a bug text data corpus; extracting, from the bug text data corpus, a statement S for describing a bug, and processing S and taking same as a subsequent input statement; constructing an entity and relationship joint extraction model; acquiring an entity set E and a relationship set R corresponding to the input statement in conjunction with the established entity and relationship joint extraction model based on a transfer system; and outputting the entity set E and the relationship set R to complete joint extraction of entities and relationships. The invention helps a software developer to quickly and efficiently understand bug information to complete bug repair.
