A Joint Model for Definition Extraction with Syntactic Connection and Semantic Consistency
Table 6: Per class performance on Textbook and Contract datasets of DEFT corpora.
['[EMPTY]', 'Textbook P', 'Textbook R', 'Textbook F1', 'Contract P', 'Contract R', 'Contract F1']
We study the per class performance of the proposed model for terms and definitions in this section. (i.e, B-Term, I-Term, B-Definition, and I-Definition) of the model on the Textbook and Contract test sets. In general, we see that extracting terms is more manageable than definitions on both Textbook and Contract due to the better performance of B-Term over B-Definition and I-Term over I-Definition (except for I-Term vs I-Definition on Textbook). This is reasonable as definitions are often presented in much more complicated expressions than terms.
