适配Turnitin“英文短语匹配+语义相似度”算法,重点优化连续单词重复、被动语态过多问题,确保英文论文达标。
Turnitin核心特性:
① 数据库覆盖全球英文期刊、学位论文、网络资源,英文比对精准;② 对连续3个及以上英文单词重复敏感,侧重学术短语相似度比对;③ 可识别AI生成的英文内容(标准化句式、被动语态过多)。
针对性降重策略:
1. 优化连续单词重复:替换核心动词/名词,调整短语结构。示例:原句“machine learning is widely used in medical diagnosis”→ 改为“machine learning has been extensively utilized in the field of medical diagnosis”;
2. 减少被动语态:多用主动语态,增强原创感。示例:原句“the experiment was conducted by the research team”→ 改为“the research team conducted the experiment and recorded key data”;
3. 重构语义逻辑:避免逐句翻译中文内容,按英文学术写作逻辑改写。示例:原直译句“With the development of AI, education has changed a lot”→ 改为“AI advancement has brought significant transformations to the education sector”;
4. 引用规范:按APA/MLA等格式标注引用,引用内容需加引号,标注作者、年份、页码。
高频避坑点:
① 不可直接抄袭英文教材、网络文章(Turnitin覆盖最全);
② 避免过度使用复杂词汇,确保表述符合英文学术规范;
③ 提交前用Turnitin的“Similarity Report”定位重复短语,精准优化。
