Public information services and documents should be accessible to the widest possible readership. Information in newspapers often takes the form of numerical expressions which pose comprehension problems for people with limited education. A first possible approach to solve this important social problem is making numerical information accessible by rewriting(More)
Are numbers expressed as digits easier to read and understand than written with letters? What about fractions and percentages? Exact or rounded values? We present an eye-tracking study that attempts to answer these questions for Spanish, using fixation and reading time to measure readability as well as comprehension questions to score understandability. We(More)
1 WCAG 2.0 (W3C Recommendation 11 Dec. 2008) recommendation includes a specific guideline regarding the readability of text contents. This paper presents an approach to adapt text to improve readability. We use existing guidelines for the development of easy to read materials together with natural language processing (NLP) methods to adapt text for people(More)

In this paper we present the results of an empirical study carried out on a parallel corpus of original and manually simplified texts in Spanish and a subsequent survey, with the aim of targeting simplification operations concerning numerical expressions. For the purpose of the study, a " numerical expression " is understood as any phrase expressing(More)
pportunities for ecological restoration and rehabilitation of degraded ecosystems in the Americas are likely to multiply in the coming decades. Ecological restoration experiments will become increasingly valuable and necessary under several projected scenarios: abandon-ment of production systems associated with rural–urban migration and economic(More)
Numerical information is very common in all kinds of documents from newspapers and magazines to household bills and wage slips. However, many people find it difficult to understand , particularly people with poor education and disabilities. Sometimes numerical information is presented with hedges that modify the meaning. A numerical hedge is a word or(More)
Conceptual frameworks of dryland degradation commonly include ecohydrological feedbacks between landscape spatial organization and resource loss, so that decreasing cover and size of vegetation patches result in higher water and soil losses, which lead to further vegetation loss. However, the impacts of these feedbacks on dryland dynamics in response to(More)
Information in newspapers is often showed in the form of numerical expressions which present comprehension problems for many people, including people with disabilities, illiteracy or lack of access to advanced technology. The purpose of this paper is to motivate, describe, and demonstrate a rule-based lexical component that simplifies numerical expressions(More)
