Multichannel Convolutional Neural Network for Biological Relation Extraction

Table 2

An example for preprocessing of sentence “Caution should be exercised when administering nabumetone with warfarin since interactions have been seen with other NSAIDs” in DDI task. There are 3 entities in this example, and thus 3 entity pairs would be generated.

Entity1	Entity2	Generated inputs
Nabumetone	warfarin	Caution should be exercised when administering Entity1 with Entity2 since interactions have been seen with other EntityOther
Nabumetone	NSAIDs	Caution should be exercised when administering Entity1 with EntityOther since Interactions have been seen with other Entity2
Warfarin	NSAIDs	Caution should be exercised when administering EntityOther with Entity1 since interactions have been seen with other Entity2
