Grid-based indexing of a newswire corpus

Abstract

In this paper we report experience in the use of computational grids in the domain of natural language processing, particularly in the area of information extraction, to create query indices for information retrieval tasks. Given the prevalence of large corpora in the natural language processing domain, computational grids offer significant utility to researchers in the domain who are reaching the bounds of computational efficiency. We leverage the affinities between the segmented data sources prevalent in natural language processing and the parallelisation model from the grid domain. The experiment reported here is a large-scale newswire corpus indexing task, with the goal to efficiently cr..
