The intelligent information retrieval system of traffic laws and regulations is introduced. The system adopts artificial intelligence technology and information push-pull technology, establishes an intelligent retrieval model based on memory network, and realizes intelligent fuzzy retrieval of information. The profits of shipping can be said to be huge, but at present, the global shipping market continues to decline, with excess production capacity and fierce market competition. Therefore, in order to revitalize shipbuilding and shipping, and speed up the structural adjustment of the shipping industry, we need to integrate the facts of the case. The described features propose an improved TextRank keyword extraction method, and the effectiveness of the improved algorithm in case keyword extraction is verified by experiments. The characteristics and technical application of intelligent ships are analyzed, and specific measures for intelligent research are put forward to provide reference for ship design and manufacturing industry personnel.
