# News Sentiment Analysis & Hindi Text-to-Speech (TTS) Web Application
|
| 2 |
+
|
| 3 |
+
## Objective
|
| 4 |
+
This project is a web-based application that:
|
| 5 |
+
- Extracts key details from multiple news articles about a **user-provided company**
|
| 6 |
+
- Performs **sentiment analysis**
|
| 7 |
+
- Conducts **comparative sentiment analysis**
|
| 8 |
+
- Generates a **Hindi Text-to-Speech (TTS)** audio report
|
| 9 |
+
- Provides a user-friendly interface for interaction
|
| 10 |
+
|
| 11 |
+
The tool allows users to input a company name and receive a **structured sentiment report** along with **audio output**.

+
## Features
|
| 16 |

1. **News Extraction**: Scrapes and displays the title, summary, and metadata from at least 10 unique news articles (non-JavaScript pages) using **BeautifulSoup (bs4)**.
|
| 17 |
+
2. **Sentiment Analysis**: Determines the sentiment (positive, negative, neutral) of each article.
|
| 18 |
+
3. **Comparative Analysis**: Compares sentiment across articles to visualize sentiment distribution.
|
| 19 |
+
4. **Hindi TTS Generation**: Converts summarized insights into Hindi audio using an open-source TTS model.
|
| 20 |
+
5. **User Interface**: Simple web UI built with **Streamlit** or **Gradio**.
|
| 21 |
+
6. **API Communication**: Frontend and backend communicate via **REST APIs**.
|
| 22 |
+
7. **Deployment**: Live deployment on **Hugging Face Spaces**.
|
| 23 |
+
8. **Documentation**: Complete setup and usage guide.

## API Development & Usage
|
| 73 |
+
|
| 74 |
+
### Backend APIs:
|
| 75 |
+
- **Endpoint**: `/analyze_news`
|
| 76 |
+
- **Method**: POST
|
| 77 |
+
- **Input**: `{"company": "Company Name"}`
|
| 78 |
+
- **Output**: List of news articles with metadata
|
| 79 |
+
|
| 80 |
+
### Testing with Postman:
|
| 81 |
+
1. Set API base URL as `http://localhost:8000/`
|
| 82 |
+
2. Select appropriate endpoints and POST body
|
| 83 |
+
3. Test responses for JSON or audio file streaming

## Third-Party API Usage
|
| 88 |
+
| API/Library | Purpose |
|
| 89 |
+
|------------------------|--------------------------------------------------------|
|
| 90 |
+
| **News scraping** | BeautifulSoup (no external news APIs used) |
|
| 91 |
+
| **Hugging Face models**| Sentiment analysis & summarization |
|
| 92 |
+
| **gtts** | Hindi Text-to-Speech generation |
|
| 93 |
+
|
| 94 |
+
---
|
| 95 |
+
|
| 96 |
+
## Assumptions & Limitations
|
| 97 |
+
- **Scraping Limitations**: Only static, non-JS websites are scraped due to `BeautifulSoup` limitations. Also newsorg pi is also used.
|
| 98 |
+
- **Article Count**: A minimum of 10 articles is targeted, but the count may vary based on search results.
|
| 99 |
+
- **Language Support**: Sentiment analysis is primarily in English, TTS is specifically Hindi.
|
| 100 |
+
- **Deployment**: Optimized for Hugging Face Spaces; heavy TTS models may experience latency. Due to flask being used hugging face is not able to run two files at a time
