Abstract: A GPU-based system for optimizing rich metadata management and a method thereof are disclosed. The system includes: a search engine for converting rich metadata information into traversal information and/or search information of a property graph, and providing at least one API according to a traversal process and/or a search process; a mapping module for detecting relationships among entity nodes in the property graph by means of mapping; a management module for activating a GPU thread group and allotting video memory blocks, so as to store the property graph in a GPU as a mixed graph; and a traversal module for activating a traversal program and performing detection and gathering on stored property arrays for iteration, so as to feed back a result of the iteration to the search engine. The system and the method are efficient in rich metadata search while having good scalability and compatibility.
