# Issue: Replace Current URL with Student Feedback

## Description
The current project workflow utilizes a URL pointing to a hotel review page on TripAdvisor for data extraction and sentiment analysis. However, for better relevance to the project's objective, it is proposed that this URL be replaced with a URL leading to a **student feedback**.

## Rationale
- **Relevance**: The project is aimed at helping international students by providing real-time translation and analysis of educational content. Utilizing a student feedback form aligns more closely with this objective.
- **Improved Data Quality**: Student feedback forms will provide more pertinent data for analysis, ensuring that the AI services are working with relevant content that reflects students' experiences and needs.
- **User-Centric Approach**: This change will allow the workflow to better serve its intended user base—international students—by focusing on their feedback rather than unrelated data.

## Proposed Solution
1. **Identify a Suitable Student Feedback Form**: Locate or create a URL that points to a student feedback form, preferably one that is widely used or relevant to the target audience.
2. **Update Main.xaml**:
- Replace the current TripAdvisor URL with the student feedback form URL.
- Adjust the data extraction logic to match the structure of the student feedback form.
3. **Test the Changes**:
- Run the updated workflow using `Test.xaml` to ensure that the new URL is correctly integrated and that data extraction and processing are functioning as expected.
4. **Documentation**:
- Update the README file and any relevant documentation to reflect the change.

## Impact
This change will make the workflow more relevant and useful to its intended audience by focusing on student feedback rather than unrelated hotel reviews.

## Additional Notes
- If there are any specific requirements for the student feedback form (e.g., format, accessibility), these should be documented and communicated to the team responsible for identifying or creating the form.

Start by inspecting Main.xaml and Test.xaml to locate the current TripAdvisor URL and understand the existing extraction and processing flow. Identify a suitable student feedback form, update the workflow and README as described, then run Test.xaml to verify that extraction, sentiment analysis, and translation still work with the new source.
