The specific steps were as follows:
1 Open the webpage and use the developer tools to view the webpage source code.
2. You can view all of the web page's elements and text in the developer tools.
3 Use a text editor (such as Sublime Text, Atom, etc.) to open the source code of the web page and use the "check elements" function in the text analysis tool to find the webpage elements.
4. If you find the element, you can check its attributes and extract the text content.
5 You can use the "Search" function of the text analysis tool to find specific text content such as keywords, titles, passages, etc.
It should be noted that extracting the text from the webpage requires a certain understanding of the webpage content in order to accurately locate and extract the required content.
Extracting text from a web page usually requires the browser's built-in translation or text extraction tools. Here are some common tools and techniques:
1. Browser translation: You can use the translation function of the browser to translate the text in the webpage into the target language. Press the "Shift + L" key in the Google Chrome-based browser to activate the translation function.
2. Text extraction tool: Many websites provide text extraction function that can automatically save the text in the web page into a local file. Common text extraction tools included Baidu Translate, Google Translate, Bing Translate, Scrapy, and so on.
3. Automatic text editor: You can use Python and other programming languages to write an automatic text editor that uses crawling technology to automatically extract text from the website. For example, a library such as Selenium could be used to simulate a user operating a browser to execute the corresponding webpage operation to obtain the text in the webpage.

2. Use an external PDF-editor in your browser: If your browser doesn't have a built-in PDF-editor, you can try using an external PDF-editor in your browser, such as the PDF-editor in Android or Google Chrome. Search for and enable these tools in the browser settings and you can paste and copy the text in the PDF.
3. Use the download tool: If the webpage provides a download button or download link, you can use the download tool to copy the text in the webpage. For example, open a web page in the browser and then click the "download" button of the browser or use the shortcut key F5 to open the download link. This way, you can download the text in the web page to the local computer.
Regardless of which method you use, you need to make sure that you save the web page in either the HD or the PDF-format before copying the text. This ensured that the text could be pasted and copied correctly and could be processed later.
Extracting text usually requires the use of natural language processing techniques. Here are some common methods:
1 Bag-of-Words Model: Transform the text into a vocabulary and select the most frequently appearing words as keywords. This method is suitable for the situation where the text volume is small and can quickly identify keywords in the text.
2. The TF-IDF (Term-frequency-inverse Document Frequency Model): Transform the text into a word frequency and calculate the importance of each word. This method is suitable for the situation where the text volume is large, and it can identify high-frequency words and keywords in the text.
3. Word sense disambiguation: classify the words in the text to better identify keywords. This method requires the text to be divided into words and then classify each word using the part-of-speech tagging tool.
4. Stop list (stop list): This includes some common stop words and phrases such as "the","of","and","belong", etc. These words are usually not used to express specific meanings but can be identified as keywords.
Each of the above methods had its advantages and disadvantages. The specific method to use depended on the application scenario and data.
