CrossCheck 国际论文英文文章查重规则算法和原理详细介绍

CrossCheck是一种基于文本比较的论文抄袭检测技术,用于检测给定的英文论文文本是否与其他可用文本存在重复。它使用一种叫做“相似短语搜索”的技术来检测论文中的重复段落。

CrossCheck 采用了一种称为“哈希比较”的技术,其原理是将文本分割成一个个短语,并将每个短语转换成一个特定的哈希值（hash）,然后将这些哈希值进行比较,以检测是否有重复的短语。

CrossCheck 在比较过程中,会考虑短语的上下文,以更好地检测出可能的抄袭。它还会考虑不同的文献类型（如学术文章、报告、书籍等）之间的不同抄袭风格,以提高抄袭检测的准确性。

CrossCheck 使用的算法和原理是,文本被分成一个个短语,每个短语都有相应的哈希值。这些哈希值会与另一份文本中的哈希值进行比较,如果发现有重复的哈希值,则认为该文本存在抄袭。CrossCheck 还会考虑文本的上下文,以提高抄袭检测的准确性。

Turnitin 国际论文英文文章查重规则和原理

Turnitin is a comprehensive tool for detecting plagiari in academic papers. It uses a combination of algorithms and databases to identify potential sources of plagiari.

1. Algorithmic Rules, Turnitin uses a set of algorithms to detect plagiari. These algorithms search for similarities between a submitted paper and the works stored in its database. They compare sentence structure, word choice, and other textual features to detect any matches. Additionally, these algorithms can identify copied and pasted phrases, as well as other attempts to mask plagiari.

2. Database, Turnitin also relies on its extensive database of works from various sources to identify potential sources of plagiari. This comprehensive database allows Turnitin to detect plagiari even if it is not found in the same language. Additionally, the database is constantly updated to include new works.

3. Reporting, Once Turnitin has identified potential sources of plagiari, it produces a report that outlines the matches it has found. This report includes information about the source of the match, as well as the percentage of similarity between the submitted paper and the source. This allows instructors to quickly and easily identify any potential sources of plagiari.

Overall, Turnitin is an effective tool for detecting plagiari in academic papers. Its combination of algorithms and databases make it an invaluable tool for instructors who need to identify and address instances of plagiari.
