Real-time online audio searching systems require high performance indexing architecture for massive audio fingerprints. To improve the performance of hash table based indexing for audio fingerprints, this paper designs and evaluates a hybrid data structure which combines linked list with vector to store the values in the hash table to balance the searching performance and the memory usage. To extend...
The efficiency of data retrieval from massive heterogeneous astronomical catalogs, as well as integration of various astronomical data retrieval services, are both key problems in astronomical data retrieval. This paper introduces a platform for Massive Heterogeneous Astronomical Data Retrieval (MHADR) which has been applied to the data center of National Astronomical Observatory of China. It proposes...
