Implementation of a System for Fast Text Search and Document Comparison
Abstract: This chapter presents an architecture of the system for fast text search and documents comparison with main focus on N-gram-based algorithm and its parallel implementation. The algorithm which is one of several computational procedures implemented in the system is used to generate a fingerprint of analyzed documents as a set of hashes which represent the file. This work examines the performance of the system, both in terms of a file comparison quality and a fingerprint generation. Several tests were conducted of N-gram-based algorithm for Intel Xeon E5645, 2.40 GHz which show approximately 8x speedup of multi over single core implementation.
