The work aimed to identify the needs that still permeated the tools of analysis and detect plagiarism for further development of a new tool, called Miss Marple, which met the requirements identified in the course of research, besides continuing the work called DIP - Evidence of Plagiarism Detector. The research conducted in this work allowed the survey of the characteristics of each tool enabling trace a comparative study between them and the development of the new tool. The validation of the developed tool was performed in two modes of travel, and distance, and by evaluating the usability of the tool. The results showed that Miss Marple tool, developed, presented good results in the analysis of percentage signs of plagiarism coming to an accuracy of approximately 100% and got the best processing time when compared with three of the tools that were studied (Sniffer plagiarism, Plagius detector and VIPER). In addition to the processing time and consistency analysis of evidence of plagiarism, another factor that deserves mention is the construction of the repository file submitted for analysis, which provides the user access to the texts with similar passages that are stored locally on your hardware. / O trabalho desenvolvido objetivou identificar as necessidades que ainda permeavam as ferramentas de análise e detecção de indícios de plágio para posterior desenvolvimento de uma nova ferramenta, denominada Miss Marple, a qual atendesse aos requisitos identificados no decorrer das pesquisas, além de dar continuidade ao trabalho desenvolvido denominado DIP - Detector de Indícios de Plágio. As pesquisas realizadas no decorrer deste estudo possibilitaram o levantamento das características de cada ferramenta estudada, possibilitando tracejar um comparativo entre as mesmas e o desenvolvimento da nova ferramenta. A validação da ferramenta desenvolvida foi realizada em duas modalidades de curso, presencial e a distância, além da avaliação de usabilidade da ferramenta. Os resultados alcançados evidenciaram que a ferramenta Miss Marple, desenvolvida, apresentou bons resultados nas análises de percentual de indícios de plágio chegando a uma precisão aproximada de 100% e obteve o melhor tempo de processamento quando comparada com três das ferramentas que foram estudadas (Farejador de Plágio, Plagius detector e VIPER). Além do tempo de processamento e consistência da análise de indícios de plágio, outro fator que merece destaque é a construção do repositório de análise por arquivo submetido, o qual proporciona ao usuário o acesso aos textos com trechos similares que ficam armazenados localmente em seu hardware.

This comparative study focuses on the detective genre and is conducted through literary analysis with a feminist critical perspective of two of its most iconic protagonists, Sherlock Holmes and Miss Marple, created by Sir Arthur Conan Doyle in 1887 and Agatha Christie in 1930 respectively. The purpose is to attempt to establish the effect of the gender differences on these two protagonists. Both Holmes and Miss Marple are deemed as iconic in the detective genre, but the protagonists do not have similar experiences and are created by authors of different genders. Thus, the focus is to explore how gender differences are represented in the literary texts A Study in Scarlet (1887), “A Scandal in Bohemia” (1891), and The Murder at the Vicarage (1930) when it comes to their work as detectives. By using a feminist critical perspective and with the help of previous research, the differences in three central issues, that is, work methods, attitudes and method of disguise, are established. The most prominent result from the analysis is that Miss Marple has to work independently from the police force and trust another character, Leonard Clement, with what she knows hoping that Clement will use her observations to make the case move forward. By contrast, Holmes is approached by clients and even assists the police force in investigations, while Miss Marple is dismissed because of gender discrimination and ageism when she reaches out to the police force. Miss Marple is clearly a victim of gender discrimination and ageism, while Holmes is seen as eccentric but fully competent as a detective. Holmes is even described as having “extraordinary powers” while Miss Marple is described as an “old pussy” in a derogatory manner. Therefore, the results are that there is a significant difference in attitude where Holmes as a man encounters more positive attitudes and Miss Marple as a woman encounters more negative attitudes, all because of gender discrimination and ageism. These results are of great importance as it reveals what gender differences Holmes and Miss Marple encounter in their literary texts. It opens up the opportunity for more research in gender differences and gender discrimination in comparisons between protagonists. That Miss Marple is successful in the end, however, functions as a feminist statement.
