The purpose of this thesis is to explore the following research question: Are there grammatical textual differences between Encyclopedia Britannica and Wikipedia? Specifically, this study will focus on the articles for "Communism" and "Dwight D. Eisenhower" that appear in the online version of Encyclopedia Britannica and Wikipedia. Using a grammatical textual analysis, the study finds there is little difference grammatically between Encyclopedia Britannica and Wikipedia though they are very different types of systems. There are several different types of textual or contextual methods that could expand on this initial approach to find differences between Encyclopedia Britannica and Wikipedia. / Department of Telecommunications

Presented here is a bibliography representing a core collection on the Celtic and Roman religion in Roman Britain. This religion, which was formed from the mixing of Celtic and Roman religions, was truly a new religion. It was formed from two powerful but different religions. The Celts believed in nature and the power it held within everything in their world. The Romans believed in the power of their pantheon of gods and goddesses. When these two factors merged it produced a religion unlike any other in the world during the Iron Age. This bibliography will list the resources to form a core collection to be used for researching the Celtic religion and Roman religion. It will also provide resources for researching what became the religion of Roman Britain and how it can be examined through burials. It provides a variety of information from historians and archaeologist who have studied these religions in depth. Many academic libraries may already include several of the primary sources in their collections, which will minimize the cost of setting up this specialized collection.

This kind of metrics were created to help writers to evaluate their text, and recently in automatic text simplification for undercapable readers. In this work we apply these metrics to documents freely retrieved from the Internet, seeking to find correlations between legibility and relevance acknowledged to then by search engines. The initial premise guiding the comparison between readability and relevance is the statement known as Occam s Principle, or Principle of Economy. This study employs Flesch-Kincaid Grade Level in text documents retrieved from the Internet through search-engines queries and correlate it with the position. It was found a centralist trend in the texts recovered. The centralist tendency mean that the average spacing of groups of files from the average of the category they belong is meaningfull. With this measure is possible to establish a correlation between relevance and legibility, and also, to detect diferences in the way both search engines derive their relevance calculation. A subsequent experiment seeks to determine whether the measure of legibility can be employed to assist him or her choosing a document combined with original search engine ranking and if it is useful as advance information for choice and user navigation. In a final experiment, based on previously obtained knowledge, a comparison between Wikipedia and Britannica encyclopedias by employing the metric of understandability Flesch-Kincaid / Textos recuperados da Internet por interm´edio de consultas ao Google e Yahoo s ao analisados segundo uma m´etrica simples de avaliac¸ ao de inteligibilidade textual. Tais m´etricas foram criadas para orientar a produc¸ ao textual e recentemente tamb´em foram empregadas em simplificadores textuais autom´aticos experimentais para leitores inexperientes. Nesse trabalho aplicam-se essas m´etricas a texto originais livres, recuperados da Internet, para buscar correlacionar o grau de inteligibilidade textual com a relev ancia que lhes ´e conferida pelos buscadores utilizados. A premissa inicial a estimular a comparac¸ ao entre inteligibilidade e relev ancia ´e o enunciado conhecido como Princ´ıpio de Occam, ou princ´ıpio da economia. Observa-se uma tend encia centralista que ocorre a partir do pequeno afastamento m´edio dos grupos de arquivos melhor colocados no ranking em relac¸ ao `a m´edia da categoria a que pertencem. ´E com a medida do afastamento m´edio que se consegue verificar correlac¸ ao com a posic¸ ao do arquivo no ranking e ´e tamb´em com essa medida que se consegue registrar diferenc¸as entre o m´etodo de calcular a relev ancia do Google e do Yahoo. Um experimento que decorre do primeiro estudo procura determinar se a medida de inteligibilidade pode ser empregada para auxiliar o usu´ario da Internet a escolher arquivos mais simples ou se a sua indicac¸ ao junto `a listagem de links recuperados ´e ´util e informativa para a escolha e navegac¸ ao do usu´ario. Em um experimento final, embasado no conhecimento previamente obtido, s ao comparadas as enciclop´edias Brit anica eWikip´edia por meio do emprego da m´etrica de inteligibilidade Flesch-Kincaid Grade Level
