  • 133-2012: Dickens Vs. Hemingway: Text Analysis And
    SAS Global Forum 2012 Data Mining and Text Analytics Paper 133-2012 Dickens vs. Hemingway: Text Analysis and Readability Statistics in Base SAS® Jessica Hampton, Cigna Corporation, Bloomfield, CT ABSTRACT Although SAS® provides a specific product for text mining (SAS Text Miner), you may be surprised how much text analy- sis you can readily perform using just Base SAS. The author introduces the topic with some background on widely-used readability statistics and tests in addition to a brief comparison of Hemingway and Dickens. After selecting two appropri- ate readability tests and texts of similar length, she describes data preparation challenges, including how to deal with punctuation, case, common abbreviations, and sentence segmentation. Using a few simple calculated macro variables, she develops a program which can be re-used to calculate readability tests on any sample input text file. Finally, she vali- dates her SAS output using published readability statistics from sources such as Amazon and searchlit.org. INTRODUCTION Charles Dickens and Ernest Hemingway represent two very different writing styles. Dickens (1812 - 1870), a popular Vic- torian novelist whose writing often included social reform themes, was paid by the word. Hemingway (1899 – 1961), war correspondent-turned-author of American literary classics, was known for his brevity and simplicity of style. These differ- ences can be quantified using common readability statistics and appropriate readability tests. Readability statistics allow those in various fields (education, healthcare, publishing, military/government, technical docu- mentation) to predict the reading difficulty of a given text or texts. Common readability statistics include the following: total character count, total word count, total sentence count, total paragraph count, average word length, average sentence length, average paragraph length, passive sentence ratio, and distinct word count.

  • The Readability of Two Grade 4 Natural Sciences Textbooks for South African Schools
    Lucy Sibanda The readability of two Grade 4 natural sciences textbooks for South African schools Abstract This paper, deriving from a larger study, evaluates the readability of two Grade 4 natural sciences textbooks used by learners who speak English as an additional language in two South African schools. The study is set within the context of the reading-related transitional challenges faced by English second language learners when they move from the foundation phase to the intermediate phase. Text readability is critical for educational achievement during this transition. The case study was conducted by means of a qualitative content analysis of factors that are not accommodated in the readability formulae which were used to investigate the textbooks. While the findings from the two instruments were ambivalent for Book 1, with the content analysis showing the book to be largely readable, but the readability calculator indicating it to be beyond the learners’ reading level, both instruments indicated poor readability for Book 2. The study recommends a close consideration of text readability by both authors and teachers.

  • Thesis the Effects of User Expectations on Website
    THESIS THE EFFECTS OF USER EXPECTATIONS ON WEBSITE INFORMATION COMPREHENSION AND SATISFACTION Submitted by Anna Harvilla Department of Journalism and Technical Communication In partial fulfillment of the requirements For the Degree of Master of Science Colorado State University Fort Collins, Colorado Summer 2014 Master’s Committee: Advisor: Jamie Switzer Pete Seel Lucy Troup Copyright by Anna Harvilla 2014 All Rights Reserved ABSTRACT THE EFFECTS OF USER EXPECTATIONS ON WEBSITE INFORMATION COMPREHENSION AND SATISFACTION The purpose of this qualitative study was to examine the role of users’ expectations of a website information search in determining their comprehension of the information on a website and their satisfaction with the website. Interviews to determine their satisfaction with the website and think-aloud sessions were employed to gather data from participants, and open coding was used to analyze responses. The findings of this study support the previous literature on scripts with respect to the usability of the Veterans Affairs website. The study found that scripts are present before users search for information on a website. Those scripts provide users with a strategy to find needed information efficiently, but when a website fails to conform to a user’s script, users experience a more difficult search and lower satisfaction with the website. More research into the particular scripts that inform users website searching strategies will help to encourage better communication on websites. Adhering to the Plain Writing Act (2010)

    Métodos de Avaliação de Apreensibilidade das Informações Textuais: uma Aplicação em Sítios de Governo Eletrônico Stefan Martins e Lucia Filgueiras Escola Politécnica da Universidade de São Paulo Departamento de Engenharia de Computação e Sistemas Digitais Av. Prof. Luciano Gualberto – trav. 3, nº. 158 – 05508-900 – São Paulo – SP – Brasil {lucia.filgueiras, stefan.martins}@poli.usp.br Resumo: A apreensibilidade das informações textuais é um atributo da inteligibilidade de um sistema. No entanto, a literatura sobre avaliações de usabilidade não detalha como avaliar se as informações que estão na forma de textos podem ser compreendidas pelo público alvo. Este estudo apresenta um conjunto de técnicas de avaliação da apreensibilidade das informações textuais e aplica duas delas a sites de governo eletrônico. A aplicação mostra que a maioria dos textos analisados está inadequada para o nível educacional da população brasileira. Palavras-chave: apreensibilidade das informações textuais, métodos de avaliação de usabilidade, governo eletrônico, índice de Flesch-Kincaid, Técnica de Cloze. 1 Introdução Este trabalho apresenta técnicas de avaliação de apreensibilidade das informações textuais, com o objetivo de incrementar os métodos tradicionais de usabilidade com avaliações de legibilidade e apreensibilidade. Na literatura clássica da área de avaliação de usabilidade, dá-se ênfase aos aspectos de inteligibilidade, de facilidade de aprendizado, de operacionalidade e de satisfação das interfaces. O foco é a comunicação entre homem e computador, sobre a linguagem que se projeta e se estabelece na experiência de uso. O texto é freqüentemente ignorado nestas análises, como se por si ele fosse compreensível. Não é objetivo deste estudo questionar a legibilidade das informações na tela do computador, como tamanho de letra adequados, espaçamentos, cor, tamanhos de parágrafos, quantidade de rolagens em um texto e outros tantos.

  • A Readability Analysis of Online Cardiovascular Disease-Related Health Education Materials
    ArticleOriginal Label Research A Readability Analysis of Online Cardiovascular Disease-Related Health Education Materials Varun Ayyaswami, BS; Divya Padmanabhan, BS; Manthan Patel, MS; Arpan Vaikunth Prabhu, MD; David R. Hansberry, MD, PhD; Nitin Agarwal, MD; and Jared W. Magnani, MD, MS ABSTRACT Background: Online cardiovascular health materials are easily accessible with an Internet connection, but the readability of its content may limit practical use by patients. Objective: The goal of our study was to assess the readability of the most commonly searched Internet health education materials for cardiovascular dis- eases accessed via Google. Methods: We selected 20 commonly searched cardiovascular disease terms: an- eurysm, angina, atherosclerosis, cardiomyopathy, congenital heart disease, coronary artery disease, deep vein thrombosis, heart attack, heart failure, high blood pressure, pericardial disease, peripheral arterial disease, rheumatic heart disease, stroke, sudden death, valvular heart disease, mini-stroke, lower extremity edema, pulmonary embolism, and exertional dyspnea. Terms were selected on Google and selected up to 10 results in order of presentation in the search results by reviewing a maximum of 15 pages of Google search results specifically providing education toward patients to yield 196 total patient education articles.Key Results: All readability measures assessing grade level measures found the 196 articles were written at a mean 10.9 (SD = 1.8) grade reading level. Moreover, 99.5% of the articles were written beyond the 5th- to 6th-grade level recommended by the American Medical Association. Conclusions: Given the prominent use of online patient education material, we consider readability as a quality metric that should be evaluated prior to online publi- cation of any health education materials.

  • Curiously Unique: Joseph Smith As Author of the Book of Mormon
    Curiously Unique: Joseph Smith as Author of the Book of Morm Brian C. Hales [Page 151]Abstract: The advent of the computer and the internet allows Joseph Smith as the “author” of the Book of Mormon to be compared to other authors and their books in ways essentially impossible even a couple of decades ago. Six criteria can demonstrate the presence of similarity or distinctiveness among writers and their literary creations: author education and experience, the book’s size and complexity, and the composition process and timeline. By comparing these characteristics, this essay investigates potentially unique characteristics of Joseph Smith and the creation of the Book of Mormon. Historically, many critics have dismissed the Book of Mormon by classifying its creation as remarkable but not too remarkable. As naturalist Dan Vogel explains: “The Book of Mormon was a remarkable accomplishment for a farm boy …. While Smith continued to produce religious texts, the Book of Mormon remained his most creative, ambitious work in scope and originality.”1 Like Vogel, skeptics commonly assume that human creativity, ambition, and originality can produce texts like the Book of Mormon and imply that past authors have used those abilities to produce similar volumes. Despite such assumptions, no attempts to duplicate his effort or to actively compare Joseph Smith to other authors have been published. Admittedly, devising a scheme for comparison can be tricky. Multiple variables could be chosen, each detecting a potentially useful parallel or nonparallel. This essay will compare six criteria regarding the author, the book, and the composition process: 1.

  • Readability of the Common Core Standards 11-Ccr Text Exemplars: a Text Sequence Reference Guide
    READABILITY OF THE COMMON CORE STANDARDS 11-CCR TEXT EXEMPLARS: A TEXT SEQUENCE REFERENCE GUIDE by Jenell A. Carapella A Master’s Project Submitted in Partial Fulfillment of the Requirements for the Degree of Master of Science in Education Department of Curriculum and Instruction State University of New York University at Fredonia Fredonia, New York August 2012 Abstract For a smooth transition, secondary students must be equipped with the skills to navigate and comprehend texts associated with college and career readiness. Educators are concerned that a gap in text complexity may cause some students’ lack in readiness. Although many factors play a part in students’ comprehension of a text (e.g. readability, the purpose for reading, and motivation), readability statistics may predict comprehensibility. This research used the Flesch- Kincaid and SMOG readability formulas to evaluate the readability grade levels of Common Core State Standards (CCSS) 11-CCR text exemplars. Results indicate that CCSS texts were, on average, within the expected grade level band, informational texts are more complex than literary texts, and the Flesch-Kincaid readability formula evaluates the texts as less complex, on average, than the SMOG formula. The results informed the development of the Text Sequence Reference Guide that rank orders all 34 CCSS 11-CCR grade level texts according to their relative complexity. This reference guide may prove useful when developing an English Language Arts curriculum that aligns with the new standards. Keywords: readability,

Freahat Faculty of Languages and Translation, Al-Imam Mohammad Ibn Saud Islamic University, Saudi Arabia Abstract—This study aimed to analyze the readability, appropriateness and difficulty level of the reading texts in Action Pack 11 (hereafter AP11) which is taught for grade 11, Action Pack 12 (hereafter AP 12) that is taught for grade 12 at the schools of The Jordanian Ministry of Education and New Headway Plus Pre-intermediate (hereafter NHWP) that is taught for an introductory English language course in the Jordanian Universities. The sample of the study involved 274 eleventh grade students, 300 twelfth grade students, and 310 freshmen students who were studying CL 099 at Yarmouk University in the academic year 2011/2012. The study employed Flesch Grade Level and Flesch Kincaid Reading Ease formulas to identify the readability level of each textbook. Furthermore, a sixth- word deletion cloze test version of a representative text from each textbook was used to identify the match between the textbooks and the students. The findings of the study revealed that the secondary school textbooks are on average about three grade levels higher in reading difficulty than the textbook of the university level. Furthermore, the cloze test results showed that the majority of the students studying each textbook were at their frustration reading levels.
