The Implementation Knowledge Graph of Air Crash Data based on Neo4j

The characteristics of neo4j graph database has been introduced, several methods of constructing graph database based on neo4j importing data have been compared and analyzed, and the “neo4j-admin” method has been finally selected to import the air crash data, to realize the visual display and query. Specific implementation steps as follows:(1) Data sets of air crash worldwide since 1908 [1] have been cleaned and preprocessed to remove incomplete lines and unimportant fields;(2) Crashed aircraft information table, accident details table and the above two table association relationship table have been designed and stored in the form of CSV files;(3)The CSV files have been imported into neo4j using the tool “neo4j-admin”, air crash knowledge graph has been generated; (4) This knowledge graph can be used to query the number of accidents since 1908, the place where the accidents occurred, the number of casualties and the time when the accidents occurred.
