Objective

To develop a platform that analyzes traveler reviews and feedback to determine sentiment, identify trends, and provide actionable insights for travel agencies, hotels, and event organizers. The system uses natural language processing (NLP) to classify reviews as positive, negative, or neutral and highlights common topics or issues.

Key Features

Technology Stack

Frontend (User & Admin): React.js / Angular / Vue.js, Tailwind CSS / Bootstrap

Backend: Node.js (Express) / Django / Spring Boot, REST APIs

AI/ML Layer:

• NLP models using Python (NLTK, spaCy, or Transformers) for sentiment classification

• Topic modeling using LDA (Latent Dirichlet Allocation) or keyword extraction techniques

Database: PostgreSQL / MySQL (user and review metadata), MongoDB (review texts and analysis results)

Notifications: Firebase / Twilio / SendGrid for alerts

Cloud & Hosting: AWS / Azure / GCP for hosting, storage, and ML model deployment

Workflow

1. User Registration/Login → Businesses or admins create accounts.

2. Review Collection → Import reviews from sources or allow user-submitted feedback.

3. Preprocessing → Clean and preprocess review text (remove stopwords, tokenize, etc.).

4. Sentiment Analysis → ML/NLP models classify reviews into positive, negative, or neutral categories.

5. Topic & Keyword Extraction → Identify frequent topics, services, or concerns mentioned.

6. Visualization & Dashboard → Display sentiment distribution, word clouds, and trends in real-time.

7. Alerts & Notifications → Notify businesses about sudden negative feedback or spikes.

8. Admin Management → Monitor platform usage, review imports, and analytics quality.

User Roles

• Business / Admin → Import and manage reviews, analyze sentiment, receive alerts, and generate reports.

• End User / Reviewer → Submit reviews or feedback through the platform (optional).
