Automated Readability Index
The automated readability index (ARI) is a readability test for English texts, designed to gauge the understandability of a text. Like the Flesch–Kincaid grade level, Gunning fog index, SMOG index, Fry readability formula The Fry readability formula (or Fry readability graph) is a readability metric for English English usually refers to: * English language * English people English may also refer to: Peoples, culture, and language * ..., and Coleman–Liau index, it produces an approximate representation of the US grade level needed to comprehend the text. The formula for calculating the automated readability index is given below: : 4.71 \left (\frac \right) + 0.5 \left (\frac \right) - 21.43 where ''characters'' is the number of letters and numbers, ''words'' is the number of spaces, and ''sentences'' is the number of sentences, which were counted manually by the typist when the above formula was developed. Non-integer scores are alway ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Readability Test
Readability is the ease with which a reader can understand a written text. In natural language, the readability of text depends on its content (the complexity of its vocabulary and syntax) and its presentation (such as typographic aspects that affect legibility, like font size, line height, character spacing, and line length). Researchers have used various factors to measure readability, such as: * Speed of perception * Perceptibility at a distance * Perceptibility in peripheral vision * Visibility * Reflex blink technique * Rate of work (reading speed) * Eye movements * Fatigue in reading * Cognitively-motivated features * Word difficulty * N-gram analysis * Semantic Richness Higher readability eases reading effort and speed for any reader, but it makes a larger difference for those who do not have high reading comprehension. Readability exists in both natural language and programming languages though in different forms. In programming, things such as programmer comments, ch ...

English Language
English is a West Germanic language of the Indo-European language family, with its earliest forms spoken by the inhabitants of early medieval England. It is named after the Angles, one of the ancient Germanic peoples that migrated to the island of Great Britain. Existing on a dialect continuum with Scots, and then closest related to the Low Saxon and Frisian languages, English is genealogically West Germanic. However, its vocabulary is also distinctively influenced by dialects of France (about 29% of Modern English words) and Latin (also about 29%), plus some grammar and a small amount of core vocabulary influenced by Old Norse (a North Germanic language). Speakers of English are called Anglophones. The earliest forms of English, collectively known as Old English, evolved from a group of West Germanic (Ingvaeonic) dialects brought to Great Britain by Anglo-Saxon settlers in the 5th century and further mutated by Norse-speaking Viking settlers starting in the 8th and 9th ...

Gunning Fog Index
In linguistics, the Gunning fog index is a readability test for English writing. The index estimates the years of formal education a person needs to understand the text on the first reading. For instance, a fog index of 12 requires the reading level of a United States high school senior (around 18 years old). The test was developed in 1952 by Robert Gunning, an American businessman who had been involved in newspaper and textbook publishing. The fog index is commonly used to confirm that text can be read easily by the intended audience. Texts for a wide audience generally need a fog index less than 12. Texts requiring near-universal understanding generally need an index less than 8. Calculation The Gunning fog index is calculated with the following algorithm: # Select a passage (such as one or more full paragraphs) of around 100 words. Do not omit any sentences; # Determine the average sentence length. (Divide the number of words by the number of sentences.); # Count the "compl ...

SMOG Index
Smog, or smoke fog, is a type of intense air pollution. The word "smog" was coined in the early 20th century, and is a portmanteau of the words ''smoke'' and ''fog'' to refer to smoky fog due to its opacity, and odor. The word was then intended to refer to what was sometimes known as pea soup fog, a familiar and serious problem in London from the 19th century to the mid-20th century. This kind of visible air pollution is composed of nitrogen oxides, sulfur oxide, ozone, smoke and other particulates. Man-made smog is derived from coal combustion emissions, vehicular emissions, industrial emissions, forest and agricultural fires and photochemical reactions of these emissions. Smog is often categorized as being either summer smog or winter smog. Summer smog is primarily associated with the photochemical formation of ozone. During the summer season when the temperatures are warmer and there is more sunlight present, photochemical smog is the dominant type of smog formation. Duri ...
