TY - JOUR ID - 580521 AU - Batko, Michal - Gennaro, Claudio - Zezula, Pavel PY - 2005 TI - Similarity Grid for Searching in Metric Spaces PB - Springer-Verlag Heidelberg CY - Berlin SN - 3540287116 KW - distributed data KW - scalable structures KW - similarity search KW - metric space N2 - Similarity search in metric spaces represents an important paradigm for content-based retrieval of many applications. Existing centralized search structures can speed-up retrieval, but they do not scale up to large volume of data because the response time is linearly increasing with the size of the searched file. The proposed GHT* index is a scalable and distributed structure. By exploiting parallelism in a dynamic network of computers, the GHT* achieves practically constant search time for similarity range queries in data-sets of arbitrary size. The structure also scales well with respect to the growing volume of retrieved data. Moreover, a small amount of replicated routing information on each server increases logarithmically. At the same time, the potential for interquery parallelism is increasing with the growing data-sets because the relative number of servers utilized by individual queries is decreasing. All these properties are verified by experiments on a prototype system using real-life data-sets. ER -
