A Walk-based Model on Entity Graphs for Relation Extraction
Table 2: Relation extraction performance (F1 %) on ACE 2005 development set for different number of entities. * denotes significance at p < 0.05 compared to l=1.
['# Entities', '[ITALIC] l=1', '[ITALIC] l = 2', '[ITALIC] l = 4', '[ITALIC] l = 8']
Finally, we show the performance of the proposed model as a function of the number of entities in a sentence. Additionally, it is observed that for more entity pairs, longer walks seem to be required. However, very long walks result to reduced performance (l = 8).
