Inter-sentence Relation Extraction with Document-levelGraph Convolutional Neural Network
Table 3: Ablation analysis on the CDR development set, in terms of F1-score (%), for intra- (Intra) and inter-sentence (Inter) pairs.
['[BOLD] Model', '[BOLD] Overall', '[BOLD] Intra', '[BOLD] Inter']
We perform ablation analysis on the CDR dataset by separating the development set to intra- and inter-sentence pairs (approximately 70% and 30% of pairs, respectively). In general, all dependency types have positive effects on inter-sentence RE and the overall performance, although self-node and adjacent sentence edges slightly harm the performance of intra-sentence relations. Additionally, coreference does not affect intra-sentence pairs.
