AI Job Scam Detection System: Safeguarding Job Search Security with Machine Learning

AI-Job-Scam-Detector is an open-source project integrating machine learning, natural language processing (NLP), and generative AI, designed to identify fake job postings and protect job seekers from scams. The project uses Streamlit to build a user-friendly web interface, provides interpretable detection results, supports use by job seekers and recruitment platforms, and offers an automated solution for job search security.

Job scams are becoming increasingly serious in the job market, with fresh graduates and entry-level employees being vulnerable. Fake job postings are disguised as legitimate ads to defraud personal information, money, or labor. Traditional manual review is inefficient and prone to omissions when dealing with massive amounts of information, so an automated detection system is urgently needed.

Data Preprocessing and Feature Engineering

Uses Kaggle's "Real/Fake Job Posting Prediction" dataset, performing text cleaning (removing HTML tags, handling missing values, etc.).

NLP and Feature Extraction

Implements bag-of-words model and TF-IDF vectorization via NLTK and Scikit-Learn, and may use word embeddings to capture semantic relationships.

Machine Learning Classification

Uses algorithms like Random Forest and Support Vector Machine to distinguish between real and fake job postings.

Deep Learning Enhancement

Introduces TensorFlow/PyTorch to build neural networks and capture complex patterns.

Generative AI Explanation

Generates detailed explanations when detecting suspicious information to improve transparency and trust.

A simple web interface built with Streamlit allows non-technical users to input job posting text and get detection results:

• Job seekers: Screen risks before applying to avoid scam traps;
• Recruitment platforms/HR: Assist in content review to improve platform security and credibility.

The core language is Python, with dependent components:

• Data processing: Pandas, NumPy;
• Machine learning: Scikit-Learn;
• NLP: NLTK;
• Deep learning: TensorFlow/PyTorch;
• Web application: Streamlit; Forming a complete technical loop from data preparation to deployment.

The project demonstrates the potential of AI in the field of social welfare, protecting personal rights and promoting a healthy employment ecosystem. Its open-source nature allows the community to reuse and expand it (e.g., integrating more data sources, advanced models), and it also serves as a practical case for ML/NLP learners, covering the complete process.

AI-Job-Scam-Detector integrates multiple AI technologies, encapsulating complex capabilities into an easy-to-use tool to benefit ordinary job seekers. As the online recruitment market develops, the importance of such security tools will become increasingly prominent.
