【摘要】：本论文基于语篇信息理论和评价理论，尝试性地分析学术写作中抄文与原文之间的相似性，旨在提取一系列能够有效鉴别学术语篇相似性的参数。论文采用定性及描述性的研究方法，分别从宏观和微观角度对比分析抄袭案例中抄文与原文之间的相似性，从而提取出有效的宏观参数和微观参数。此外，论文还通过实验方法验证所提取宏观参数的有效性。研究发现：一、提取出的宏观参数包括信息结构与发展、核心命题、信息密度以及信息点，能够鉴别出语篇宏观信息结构，另外，该研究还分别根据信息点的频率和主客观程度对其进行了分类。二、提取出的微观参数有态度资源、级差资源以及个体、过程和环境，在微观层面对相似性语篇进行更加细致深入的分析与鉴别；三、关于宏观参数的有效性，在实验中，通过综合分析宏观参数综合鉴别出六篇抄袭摘要中的五篇。本论文的创新之处在于为学术语篇的相似性鉴别提供新的研究视角，即语篇信息和评价理论视角，具有理论和实践价值。理论上，丰富了语篇信息理论和评价理论的研究；实践上，，为相似性鉴别提供语言学上的佐证，避免学术重复，节约学术资源。
[Abstract]:Based on the text information theory and the evaluation theory, this thesis attempts to analyze the similarity between the transcripts and the original text in academic writing, in order to extract a series of parameters which can effectively identify the similarity of academic texts. In this paper, qualitative and descriptive research methods are used to compare and analyze the similarity between the copying text and the original text from the macro and micro perspectives respectively, so as to extract the effective macro and micro parameters. In addition, the validity of the extracted macro parameters is verified by experimental method. The main findings are as follows: first, the extracted macro parameters include information structure and development, core proposition, information density and information points, which can identify the macro-information structure of discourse. The study also classified the information points according to their frequency and subjective and objective degree. Secondly, the microcosmic parameters extracted are attitude resources, differential resources, individual, process and environment, and more detailed and in-depth analysis and identification of similar texts at the micro level. Third, on the validity of macroscopic parameters, in the experiment, Five of the six plagiarism abstracts were identified by comprehensive analysis of macroscopical parameters. The innovation of this thesis lies in its theoretical and practical value in providing a new perspective for the similarity identification of academic texts, namely, the perspective of text information and evaluation theory. Theoretically, it enriches the study of text information theory and evaluation theory, and in practice, provides linguistic evidence for similarity identification, avoids academic duplication and saves academic resources.
