Turnitin 国际论文英文文章查重算法规则和原理

Turnitin is an international paper checking algorithm developed by iParadigms LLC. It is widely used in universities and other educational institutions as a plagiari detection tool. The algorithm works by comparing each submitted paper to a large database of academic papers, articles, and web content.

The algorithm is based on two components, similarity index and originality report. The similarity index measures the percentage of a document that matches other sources in the Turnitin database. The originality report lists all the sources that were used for comparison and provides a percentage of each.

The first step in the algorithm is to break down each submitted paper into its constituent parts. These parts are then compared to the texts in the Turnitin database. The algorithm looks for matches in sentences, phrases, words, and even punctuation. If a match is found, the algorithm calculates the degree of similarity and assigns a percentage based on the amount of text that was matched.

At the end of the process, the algorithm gives a final score, the similarity index. This score indicates the overall similarity of the document to other sources in the Turnitin database. The originality report also provides a list of sources that were used to compare the document.

Overall, Turnitin is an effective tool for detecting plagiari and protecting academic integrity. It is a powerful algorithm that can quickly and accurately detect plagiari in documents.

CrossCheck 国际论文英文文章查重算法规则和原理介绍

CrossCheck是一种基于国际标准的文献查重算法,用于检测论文中的抄袭和重复。它基于国际标准,使用跨数据库技术,可以检测到一篇论文在不同的期刊和数据库中的重复现象。

CrossCheck的原理是,它把每一篇论文的内容都分解成一个由指纹（指纹是一个由特定的字符串组成的独特标识）构成的“特征集合”,然后将这些特征集合与其他论文中的特征进行比较,以检测重复的情况。该算法还允许用户指定一定的容差度,以便检测出更大范围内的重复现象。

CrossCheck使用一种叫做“文本相似性比较”的技术,根据文本的语法和语义特征来进行比较,以确定文章之间的重复现象。这种技术会计算文本的相似度,并把它们分级,以确定其相似性,从而检测出抄袭或重复的情况。
