Approximate textual retrieval

P. Constans. Approximate textual retrieval. arXiv:0705.0751 (2007).

Abstract
An approximate textual retrieval algorithm for searching sources with high levels of defects is presented. It considers splitting the words in a query into two overlapping segments and subsequently building composite regular expressions from interlacing subsets of the segments. This procedure reduces the probability of missed occurrences due to source defects, yet diminishes the retrieval of irrelevant, non-contextual occurrences.

Keywords
Approximate search, information retrieval, errors.
