1. **Open the Tool**: Navigate to the URL where the tool is hosted. |
|
|
2. **User Input**: |
|
|
- **Text to Analyze**: In the text area labeled "Enter text to analyze", paste or type the text you want to analyze. |
|
|
- **Query**: Optionally, you can also enter a specific query in the text input field labeled "Enter your query (optional)". This is for your own reference. |
|
|
- **Analyze**: Click the button labeled "Analyze". The tool will then process the text and perform entity analysis on it. |
|
|
3. **View Results**: |
|
|
- After the analysis is complete, you'll see a section that says, "We found X results for your query of your_query" (or just "We found results for your query" if no query was entered). |
|
|
- Below this, you'll find a line-by-line breakdown of each entity identified in the text. |
