Resume Screening AI
Advanced AI Resume Screening System
A comprehensive machine learning project demonstrating natural language processing,
text analysis, and automated candidate evaluation using modern AI techniques.
Project Overview
Learning Objectives & Industry Application
This project addresses real-world recruitment challenges:
Manual resume screening consumes significant time and resources, with human bias affecting
hiring decisions. Traditional keyword matching systems miss qualified candidates who use
different terminology. Our AI-powered solution demonstrates how machine learning and
natural language processing can automate and improve the screening process.
Educational Value: Students will learn to implement TF-IDF vectorization,
cosine similarity calculations, text preprocessing, and web application development while
solving a practical business problem with measurable impact.
Technical Solution Architecture
Natural Language Processing
Implement advanced text preprocessing, tokenization, and TF-IDF vectorization to convert unstructured resume text into analyzable numerical data.
Machine Learning Algorithms
Apply cosine similarity calculations and composite scoring models to rank candidates based on job requirements and qualifications.
Data Visualization
Create interactive dashboards using Plotly and Streamlit to present analysis results with comprehensive reporting capabilities.
Software Engineering
Develop modular, scalable code architecture with proper error handling, logging, and cross-platform compatibility.
Core Technical Components
Document Processing
Implement robust file parsing for PDF, DOCX, and TXT formats with encoding detection and error handling using PyPDF2 and python-docx libraries.
Text Analysis Engine
Build NLP pipeline with NLTK for preprocessing, TF-IDF vectorization for feature extraction, and cosine similarity for document comparison.
Scoring Algorithms
Develop composite scoring system combining semantic similarity, skill matching percentages, and weighted ranking mechanisms.
Data Visualization
Create interactive charts with Plotly including score comparisons, skill gap analysis, and statistical distribution plots.
Reporting System
Generate comprehensive analysis reports with candidate rankings, detailed breakdowns, and export capabilities to CSV and JSON.
Web Application
Deploy full-stack solution using Streamlit framework with session management, file uploads, and responsive design principles.
