Entity and relationship joint extraction method oriented to software bug knowledge

An entity and relationship joint extraction method oriented to software bug knowledge, comprising:

• step 1:
• collecting text data of an open-source bug library and preprocessing the text data to obtain a bug text data corpus;
• step 2:
• extracting, from the bug text data corpus obtained in step 1, a statement S for describing a bug, processing S, and then using the processed S as an input statement of step 4;
• step 3:
• constructing an entity and relationship joint extraction model based on a transition system;
• step 4:
• obtaining, in conjunction with the constructed entity and relationship joint extraction model based on the transition system in step 3, an entity set E and a relationship set R corresponding to the input statement of step 2;
• and,
• step 5:
• outputting the entity set E and the relationship set R obtained in step 4 to complete joint extraction of entities and relationships.
