Abstract: A method for extracting a dam emergency event based on a dual attention mechanism is provided. The method includes: performing data preprocessing, building a dependency graph, building a dual attention network, and filling a document-level argument. The performing data preprocessing includes labeling a dam emergency corpus and encoding sentences. Building a dependency graph includes assisting a model to mine a syntactic relation based on a dependency. Building a dual attention network includes weighing and fusing an attention network based on a graph transformer network (GTN) and capturing key semantic information in the sentence. Filling a document-level argument includes filling a document-level argument by detecting a key sentence and ordering a semantic similarity. The method introduces a dependency and overcomes the long-range dependency problem based on the dual attention mechanism, thus achieving high identification accuracy and reducing a lot of labor costs.

Abstract: A hydraulic ship lift, including: a mechanical synchronizing system; a stabilizing and equalizing hydraulic driving system; and a self-feedback stabilizing system. The stabilizing and equalizing hydraulic driving system includes first resistance equalizing members arranged at corners of branch water pipes or/and second resistance equalizing members arranged at bifurcated pipes, circular forced ventilating mechanisms arranged at front of water delivery valves of a water delivery main pipe, and pressure-stabilizing and vibration-reducing boxes arranged behind the water delivery valves. The self-feedback stabilizing system includes a plurality of guide wheels; each guide wheel of the self-feedback stabilizing system is fixed on a ship reception chamber through a supporting mechanism.
