Tool Introduction

"Text Similarity Detection" is an efficient online tool designed to help users quickly compare and analyze the semantic similarity between two text passages. Simply input the two texts to be compared into the designated areas, and the tool will use advanced algorithms to intelligently identify their core content and contextual relevance, ultimately providing a quantified similarity score. This is very helpful for content plagiarism checking, text comparison, article originality detection, or evaluating the correlation between different versions of text.

How to Use

Paste or type your first text content into the "Text to Compare 1" input box.
Paste or type your second text content into the "Text to Compare 2" input box.
After confirming that both texts have been entered completely and correctly, click the "Detect" or "Calculate" button on the page (the specific button name may vary depending on the interface).
The tool will immediately process your request and display the similarity score of the two texts in the result area.

Input Parameter Description:

Text to Compare 1 (text1): Required field, used to input the first text for similarity analysis. Supports plain text content of any length.
Text to Compare 2 (text2): Required field, used to input the second text to be compared with the first text. Also supports plain text content of any length.

Output Result Format:

The tool will display the calculation results in a list format, mainly including the following core metric:

Similarity (score): A floating-point value between 0 and 1. This value intuitively represents the degree of similarity between the two texts. Here, 0 means the two texts are completely dissimilar, and 1 means the two texts are identical or highly semantically consistent. The closer the value is to 1, the higher the similarity between the two texts.

Frequently Asked Questions

Q: What input formats are supported?
A: This tool supports plain text input. You can directly type or paste any text content into the text box without worrying about specific format restrictions.
Q: What is the format of the output result?
A: The output result is presented in a concise list format, primarily showing a "Similarity" value, which is a floating-point number between 0 and 1.
Q: What is the range of the similarity score, and what does it mean?
A: The similarity score ranges from 0 to 1. 0 means the two texts are completely dissimilar, and 1 means the two texts are semantically identical. A higher value indicates greater text similarity.
Q: Does text length affect similarity detection results?
A: Theoretically, text length does not directly lead to inaccurate detection results, but overly short texts may lack sufficient semantic information for in-depth analysis, while overly long texts may increase processing time. It is recommended to input paragraphs containing complete semantic information.

Notes

Please ensure that both texts you input are the complete content you wish to compare, to avoid result deviations due to truncated or incomplete text.
This tool focuses on semantic similarity detection; even if the wording or sentence structure of the two texts differs, a high similarity score may still be obtained as long as the core meaning expressed is similar.
The similarity score is a quantitative reference indicator; when making important decisions, it is recommended to combine it with manual review and contextual judgment for comprehensive assessment.
Currently, the tool does not support batch text uploads or cross-comparison between multiple texts; it can only process similarity detection for one pair of texts at a time.

Uses of Text Similarity Detection

Text similarity detection technology plays an increasingly important role in modern information processing, with wide and in-depth application scenarios:

Academic Plagiarism Check and Anti-Plagiarism: In education and research, used to detect plagiarism in theses, reports, assignments, etc., to maintain academic integrity.
Content Originality Assessment: For content creators, self-media platforms, and publishing houses, it can quickly assess the originality of articles and avoid content duplication.
Information Retrieval and Recommendation Systems: Search engines return relevant results by calculating the similarity between query terms and documents; recommendation systems provide precise recommendations based on user interests and content similarity.
Text Deduplication and Clustering: In big data analysis, used to identify and remove duplicate information, or automatically categorize semantically similar documents to improve data processing efficiency.
Customer Service and Smart Q&A: Smart customer service robots provide the most matching answers by comparing user questions with standard questions in the knowledge base, improving service efficiency.
Legal Document Comparison: In the legal industry, used to compare key clauses or content similarity in legal documents such as contracts and precedents.
