Why Similarity Increases After Editing: A Practical Guide for PhD Scholars and Researchers
Introduction
If you are a PhD scholar or academic researcher, you may have encountered a confusing and often frustrating situation where why similarity increases after editing becomes a real concern. You submit your manuscript for professional academic editing, expecting improved clarity and quality. However, when you run the revised document through plagiarism detection tools such as Turnitin or iThenticate, the similarity score unexpectedly rises. Naturally, this raises doubts about the editing process, academic integrity, and even publication readiness.
This issue is more common than many researchers realize. In fact, global academic publishing trends reveal that over 60 percent of manuscripts submitted to indexed journals undergo at least one round of professional editing before acceptance. At the same time, acceptance rates in high-impact journals often fall below 10 to 15 percent, according to data from major publishers like Elsevier and Springer. This pressure pushes scholars to refine their manuscripts intensively, often through external academic editing services.
However, the intersection of editing and similarity scores is not always straightforward. While editing improves grammar, structure, and coherence, it can also standardize language, introduce commonly used academic phrases, or align the text with discipline-specific conventions. These changes, although beneficial, can sometimes increase text matches in plagiarism detection systems.
PhD students today face multiple challenges, including limited time, publication stress, financial constraints, and the need to meet stringent academic standards. Moreover, with the growing emphasis on originality and ethical publishing, understanding why similarity increases after editing becomes essential. It is not merely a technical issue but a strategic concern that directly impacts publication success.
This article provides a comprehensive, evidence-based explanation of this phenomenon. It also offers actionable solutions, expert insights, and best practices to help you manage similarity scores effectively without compromising academic integrity. Whether you are preparing your thesis, journal article, or conference paper, this guide will help you navigate the complexities of academic editing and plagiarism detection with confidence.
Understanding Why Similarity Increases After Editing
What Does “Similarity” Actually Mean?
Before addressing why similarity increases after editing, it is crucial to understand what similarity scores represent. Tools like Turnitin and iThenticate do not detect plagiarism directly. Instead, they identify text matches against a vast database of published articles, web content, and student submissions.
According to the official guidance from Turnitin Similarity Report Overview, similarity percentages indicate overlapping text, not necessarily unethical copying. Therefore, a higher similarity score does not automatically imply plagiarism.
Why Editing Can Increase Similarity
Several factors explain why similarity increases after editing:
- Standardization of Academic Language
Editors often replace informal or inconsistent phrasing with standardized academic expressions. These commonly used phrases may already exist in multiple publications, leading to higher matches. - Improved Clarity Through Conventional Structures
Academic writing follows specific patterns, especially in methodology and literature review sections. When editors restructure sentences to align with these conventions, similarity scores can rise. - Insertion of Proper Citations and References
Adding references from established sources such as Elsevier’s plagiarism policy can increase matches because cited text often overlaps with existing literature. - Reduction of Paraphrasing Variability
Sometimes, editors refine overly complex or incorrect paraphrasing into clearer, more accurate language. Ironically, this may make the text closer to original sources. - Use of Technical Terminology
In disciplines like engineering, medicine, or data science, certain terms and phrases are unavoidable. These repeated expressions contribute to similarity percentages.
Types of Similarity That Increase After Editing
Acceptable Similarity
Not all similarity is problematic. The following are generally acceptable:
- Properly cited quotations
- Standard methodological descriptions
- References and bibliographies
- Common academic phrases
Problematic Similarity
However, certain types require attention:
- Unintentional close paraphrasing
- Over-reliance on source wording
- Lack of proper citation
Understanding this distinction is critical for maintaining ethical research standards.
Real Example: Why Similarity Increases After Editing
Consider a PhD student working on a literature review. Initially, the text contains informal paraphrasing and inconsistent structure. After professional editing:
- Sentences become more precise
- Terminology aligns with journal standards
- Citations are added correctly
As a result, the similarity score increases from 12 percent to 18 percent. Although the score rises, the quality improves significantly, and the manuscript becomes publication-ready.
This example highlights a key insight: similarity increase does not equal academic misconduct.
How Professional Academic Editing Influences Similarity Scores
Professional editors focus on:
- Grammar and syntax correction
- Logical flow improvement
- Academic tone enhancement
- Formatting and referencing
At ContentXprtz, our PhD thesis help and research paper writing support are designed to maintain originality while improving clarity.
However, editing must follow ethical guidelines. According to COPE guidelines, editors should not alter the intellectual content of a manuscript.
Practical Strategies to Manage Similarity After Editing
1. Use Advanced Paraphrasing Techniques
Instead of simple word replacement, focus on:
- Changing sentence structure
- Using different conceptual framing
- Synthesizing multiple sources
2. Check Similarity Before and After Editing
Run plagiarism checks at multiple stages to identify changes.
3. Review Editor Changes Carefully
Ensure that edits do not unintentionally increase similarity.
4. Maintain Proper Citations
Always cite sources accurately using APA, MLA, or journal-specific formats.
5. Focus on Original Contribution
Highlight your unique findings and analysis to reduce dependence on existing text.
The Role of Academic Integrity in Editing
Maintaining academic integrity is essential. According to APA plagiarism guidelines, proper citation and original thinking are fundamental to scholarly writing.
Editing should enhance clarity, not compromise originality. Therefore, understanding why similarity increases after editing helps you balance quality and ethics effectively.
Frequently Asked Questions
1. Why similarity increases after editing even with professional services?
This happens because editors align your manuscript with standard academic language. As a result, commonly used phrases appear more frequently. Additionally, improved citations and structured writing increase matches with existing literature. However, this does not indicate plagiarism. Instead, it reflects alignment with academic conventions. To manage this, always review edits and ensure originality in your analysis.
2. Is a higher similarity score always bad?
No. A higher similarity score is not always problematic. For example, references, methodology descriptions, and technical terms naturally contribute to similarity. Journals typically accept similarity scores within a reasonable range, often below 20 percent. Therefore, focus on the nature of similarity rather than the percentage alone.
3. Can editing services reduce similarity?
Yes, but only when paraphrasing and restructuring are applied carefully. Ethical editing focuses on clarity and coherence rather than artificially lowering similarity. At ContentXprtz, our academic editing services prioritize both originality and readability.
4. How can I reduce similarity after editing?
You can reduce similarity by rewriting sections, combining ideas, and adding original insights. Additionally, avoid overusing direct quotes. Instead, summarize and interpret sources in your own words.
5. Do journals reject papers based on similarity scores?
Journals evaluate both similarity scores and content quality. While high similarity may raise concerns, editors also assess context. Properly cited text is usually acceptable. Therefore, focus on originality and clarity.
6. Why do plagiarism tools show matches for common phrases?
Plagiarism tools compare your text with existing databases. Common academic phrases often appear in multiple sources. As a result, they generate matches. This is normal and usually acceptable.
7. Should I avoid professional editing to keep similarity low?
No. Professional editing improves your chances of publication. Instead of avoiding editing, choose ethical services like research paper assistance that maintain originality.
8. What similarity percentage is acceptable?
Most journals accept similarity scores below 15 to 20 percent. However, this varies by discipline and journal policy. Always check specific guidelines.
