Abstract: Highlights•A new trigger words identification method is defined based on word activation force.•A unique representation of activation force defined dependency pattern is proposed.•Two-level semantic drift suppressing strategy is adopted.•Experimental result verifies the AFDDP is a good representation of relations.
