1. Summary Because of the complex pattern and different information descriptions of graph databases, it is extremely difficult for non-professional users to query complex graph databases. A Good Graph query engine should support conversion of synonyms, acronyms, abbreviations, and ontology, and should be able to sort search results well. Based on this problem, th
