In this paper we examine the task of sentence simplification which aims to reduce the reading complexity of a sentence by incorporating more accessible vocabulary and sentence structure. We introduce a new data set that pairs English Wikipedia with Simple English Wikipedia and is orders of magnitude larger than any previously examined for sentence simplification. The data contains the full rang...

This paper presents the systems we developed while participating in the first task (English Lexical Simplification) of SemEval 2012. Our first system relies on n-grams frequencies computed from the Simple English Wikipedia version, ranking each substitution term by decreasing frequency of use. We experimented with several other systems, based on term frequencies, or taking into account the cont...

This paper addresses the issue of simplifying natural language texts in order to ease the task of accessing factual information contained in them. We define the notion of Easy Access Sentence a unit of text from which the information it contains can be retrieved by a system with modest text-analysis capabilities, able to process single verb sentences with named entities as constituents. We pres...

With the recent focus in the accessibility field, researchers from academia and industry have been very active in developing innovative techniques and tools for assistive technology. Especially with handheld devices getting ever powerful and being able to recognize the user’s voice, screen magnification for individuals with low-vision, and eye tracking devices used in studies with individuals w...

Analysing lexical complexity is a task that has mainly attracted the attention of psycholinguists and language teachers. More recently, this issue has seen a growing interest in the field of Natural Language Processing (NLP) and, in particular, that of automatic text simplification. The aim of this task is to identify words and structures which may be difficult to understand by a target audienc...

This paper deals with connected operators based on reconstruction process. New operators are proposed to perform size and motion simplification. In the case of size simplification, the proposed approach allows to better preserve the contrast of maxima or minima that have not been totally simplified by the filtering process. In the case of motion simplification, two applications are illustrated:...
