### **Title:**
**A Personalized Project Recommendation System for Final-Year BIT Students**
---
### **Abstract**
Selecting an appropriate final-year project is a critical yet challenging task for undergraduate students, especially in large and diverse programmes such as the External Degree Programme in Information Technology (BIT) offered by the University of Colombo School of Computing (UCSC). Students often struggle due to a lack of clarity on their interests, unfamiliarity with available project domains, or insufficient guidance. This dissertation presents the design, development, and evaluation of a **Personalized Project Recommendation System (PPRS)** tailored specifically for BIT final-year students. The system leverages student profiles—including academic history, skillsets, interests, and past coursework—and applies collaborative filtering and content-based filtering techniques to suggest relevant, feasible, and motivating project ideas. The prototype was built using a modern web stack (React frontend, Node.js backend, and MongoDB database) and evaluated through user testing with a sample of BIT students. Results indicate that the system significantly improves students’ confidence and relevance in project selection, thereby enhancing academic engagement and project outcomes.

### **Chapter 1: Introduction**
#### 1.1 Background
The final-year project is a capstone experience in the BIT curriculum, designed to integrate theoretical knowledge with practical application. However, many students face uncertainty when choosing a project topic due to the vast range of possibilities, evolving technology trends, and varying academic strengths. Advisors often lack the bandwidth to provide individualized guidance to hundreds of external students.
#### 1.2 Problem Statement
Students enrolled in the UCSC External BIT programme frequently report difficulty in selecting a suitable final-year project. Common issues include:
- Overwhelming number of potential topics.
- Misalignment between project scope and student capabilities.
- Lack of exposure to emerging domains (e.g., AI, cybersecurity, IoT).
- Inadequate matching between student interests and available supervisory expertise.
This leads to delayed project initiation, reduced motivation, and suboptimal academic performance.
#### 1.3 Proposed Solution
This project proposes a **Personalized Project Recommendation System (PPRS)** that recommends project ideas based on:
- Student’s academic record (e.g., passed modules, grades).
- Self-declared interests and technical skills.
- Historical data from past successful projects.
- Supervisor availability and domain expertise.
#### 1.4 Objectives
- To analyze the factors influencing project selection among BIT students.
- To design a recommendation engine using hybrid filtering techniques.
- To develop a user-friendly web interface for student interaction.
- To evaluate system effectiveness through usability and relevance metrics.
#### 1.5 Scope and Limitations
- Focuses on UCSC External BIT final-year students.
- Does not replace advisor consultation but supplements it.
- Recommendations are limited to predefined project templates and past submissions (with anonymization).
- Real-time supervisor matching is included but does not guarantee availability.

### **Chapter 2: Literature Review**
#### 2.1 Educational Recommendation Systems
Existing systems in higher education (e.g., course recommenders at MIT, Stanford) use collaborative and content-based approaches. Studies show personalized recommendations improve engagement and learning outcomes (Verbert et al., 2013).
#### 2.2 Project Recommendation in Academia
Few systems target capstone projects. Notable examples include:
- **CapRec**: Recommends software engineering projects using NLP on past abstracts.
- **ProjectMatch**: Matches students to faculty based on research keywords.
However, none are tailored to the UCSC BIT context, which combines part-time, remote learners with diverse backgrounds.
#### 2.3 Recommendation Algorithms
- **Content-Based Filtering**: Matches user profile to item features.
- **Collaborative Filtering**: Leverages similarities between users or items.
- **Hybrid Approaches**: Combine both to overcome cold-start and sparsity issues (Burke, 2002).
This project adopts a hybrid model to balance personalization and diversity.

### **Chapter 3: System Analysis and Design**
#### 3.1 Requirements Gathering
Conducted surveys (n=45) and focus groups with BIT students and advisors. Key findings:
- 78% wanted help aligning projects with career goals.
- 65% struggled to find novel yet feasible ideas.
- Preferred interface: simple, mobile-friendly, with filtering options.
#### 33.2 Functional Requirements
- User registration and profile creation.
- Project database with metadata (domain, tools, difficulty, supervisor).
- Recommendation engine with adjustable preferences.
- Save/favorite projects and export suggestions.
#### 3.3 Non-Functional Requirements
- Responsive design (mobile & desktop).
- Data privacy (GDPR-compliant anonymization).
- Scalability for 1000+ users.
#### 3.4 System Architecture
- **Frontend**: React.js with Material UI.
- **Backend**: Node.js + Express.
- **Database**: MongoDB (flexible schema for project attributes).
- **Recommendation Engine**: Python-based microservice using Scikit-learn and Cosine Similarity.
#### 3.5 Data Model
Key entities:
- **Student**: userID, modulesPassed, skills, interests, careerGoal.
- **Project**: projectID, title, description, domain, tools, difficulty, year, supervisorID.
- **Supervisor**: supervisorID, name, expertiseDomains, maxStudents.

### **Chapter 4: Implementation**
#### 4.1 Development Environment
- VS Code, Git, Docker.
- RESTful APIs for frontend-backend communication.
- JWT for authentication.
#### 4.2 Recommendation Algorithm
Hybrid approach:
1. **Content-Based**: Compute similarity between student profile vector and project feature vector.
2. **Collaborative**: If sufficient data exists, find similar students and recommend their top projects.
3. **Weighted Combination**: Final score = 0.7 × contentScore + 0.3 × collaborativeScore.
#### 4.3 Sample Workflow
1. Student logs in and completes profile.
2. System fetches matching projects.
3. Results displayed with filters (e.g., “AI”, “Web Development”, “Beginner”).
4. Student can request advisor contact or save for later.
#### 4.4 Security and Privacy
- Passwords hashed with bcrypt.
- Student data encrypted at rest.
- No collection of sensitive personal information.

### **Chapter 5: Evaluation**
#### 5.1 Methodology
- **Participants**: 30 final-year BIT students.
- **Metrics**:
- Relevance (Likert scale 1–5).
- Usability (System Usability Scale - SUS).
- Time-to-decision (before vs. after using PPRS).
#### 5.2 Results
- Average relevance score: **4.2/5**.
- SUS score: **78** (above average usability).
- 82% reduced time spent on topic selection by >50%.
#### 5.3 Feedback
- “The system helped me discover areas I hadn’t considered.”
- “Would be better with live supervisor chat.”
