Abstract: Disclosed is a linguistically-based method for searching and recommending reusable definition candidates in one or more documents and for calculating measures of reuse efficiency and reuse consistency in these documents. Some embodiments of the present invention also produce document précis, whereby common terms and other data can be replaced by short titles with a link to their description. The definition candidates and the text pr?cis can be used in search engines of large databases or of the internet to provide more valuable and efficient search results. According to additional embodiments of the present invention a tool is provided for aiding individuals with reading disabilities. The tool facilitates document comprehension processes by separating the most valuable text content e.g. the definitions part. Additionally, some embodiments of the present invention enable evaluating the pattern perception of the text writer by statistically measuring the amount of usage of definition candidates.
