Keyword Extraction

Tool Introduction

“Keyword Extraction” is a powerful online text analysis tool designed to help users quickly identify and extract the most representative core keywords from lengthy articles, reports, or other text content. Whether for content summarization, topic identification, SEO optimization, or big data preprocessing, this tool can efficiently distill key information points. Users can flexibly set the number of keywords they wish to extract, thereby precisely controlling the granularity of the output.

How to Use

1. Enter or paste the text content you need to analyze into the “Input Text” text box. This is a required field; please ensure valid text is entered.
2. (Optional) In the “Number of Keywords to Extract” input box, set the number of keywords you wish to obtain. The default value is 10, but you can adjust it to any positive integer as needed.
3. Click the “Extract” or corresponding execution button on the page, and the tool will immediately perform semantic analysis on the input text and generate a keyword list.

Frequently Asked Questions

• Q: What input formats are supported?
• A: This tool currently primarily supports plain text input. Please paste the text content you need to process directly into the input box.
• Q: What is the output format?
• A: The output is a clear list of keywords, with each keyword displayed independently, making it easy for users to review and use directly.
• Q: Is there a limit to the number of keywords extracted?
• A: You can customize the number of keywords to extract, from 1 to more. The default number is 10, but you can adjust it according to your actual needs.
• Q: How accurate are the extracted keywords?
• A: This tool employs advanced semantic analysis technology and can provide highly accurate keywords in most cases. However, for extremely specialized, complex, or highly context-dependent texts, the results may have some deviations.

Notes

• Input data format requirements: Please ensure that the input is plain text, avoiding images, special formats, or binary data, which may lead to extraction failure or inaccurate results.
• Text length: Although this tool supports extraction from longer texts, excessively long input text may increase processing time. It is recommended to extract particularly long documents in segments or use the tool when network conditions are good.
• Language support: This tool is primarily optimized for Chinese text; the keyword extraction effect for other languages may not be as good as for Chinese.
• Result interpretation: Keyword extraction is based on text statistics and semantic analysis, and sometimes may include words that are not so “core” in a specific context. It is recommended to combine with manual judgment to finally confirm the validity of the keywords.
