Hardware Support for Language Aware Information Mining

摘要

Information retrieval from text or 'text mining' is the process of extracting interesting and non-trivial knowledge from unstructured text. With the ever increasing amounts of information stored on the web or archived within a computing system, high performance data processing architectures are required to process this data in real time. The aim of the work presented in this paper is the development of a hardware text mining IP-Core for use in FPGA based systems. In this paper we will describe the pre-processing engine we have developed for the PRESENCE Ⅱ PCI card, to accelerate the identification of significant words within a document, logging their frequency and position. The performance of this system is then compared to an equivalent software implementation using the Lucene software package.
