Similarity Grid for Searching in Metric Spaces
Original language description
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

Podobnostní GRID pro hledání v metrických prostrorech
Czech description
Podobnostní hledání v centralizovaném prostředí se ukazuje nedostatečným z hlediska škálovatelnosti. GHT* je distribuovaná struktura pro podobnostní hledání, založeném na metrických prostorech, která dosahuje prakticky konstantní odezvy pro libovolně rozsáhlá data.
