1. Abstract
Automatic Resume Ranking is an AI-powered application designed to evaluate and rank candidate resumes based on their relevance to a specific job description. Using Natural Language Processing (NLP) and Machine Learning techniques, the system extracts important details such as technical skills, educational qualifications, work experience, and certifications from resumes. It compares these details with job requirements and generates a relevance score to help recruiters organize and review applications efficiently. The system aims to reduce manual screening effort and support a more structured recruitment process.
2. Objectives
- Automatically analyze and rank resumes against job descriptions.
- Extract relevant skills, education, and experience from candidate profiles.
- Calculate resume-to-job relevance scores.
- Reduce the time required for initial resume screening.
- Help recruiters identify candidates whose qualifications match the role.
- Provide a user-friendly interface for uploading resumes and viewing rankings.
3. Existing System
Traditional resume screening relies on recruiters manually reviewing applications and comparing candidate qualifications with job requirements. This process can become time-consuming when organizations receive large numbers of applications.
Disadvantages
- Manual screening requires considerable time and effort.
- Evaluating large numbers of resumes can delay recruitment.
- Different reviewers may apply inconsistent evaluation criteria.
- Relevant candidate information may be overlooked.
- Repetitive resume comparison can increase administrative workload.
4. Proposed System
The proposed system uses NLP and text similarity techniques to compare resumes with a job description. It extracts information such as skills, education, experience, and certifications, then compares these details with the specified job requirements. Techniques such as TF-IDF with cosine similarity or sentence embeddings can generate relevance scores and rank resumes accordingly. The system displays candidate rankings, matching skills, and missing job-related requirements to support recruiter review.
5. Implementation Procedure
- Resume Collection: Upload candidate resumes in PDF or DOCX format.
- Job Description Input: Enter the job title, responsibilities, required skills, and qualifications.
- Text Extraction: Extract resume text using PyMuPDF, pdfplumber, or python-docx.
- Text Preprocessing: Clean and normalize resume content and job descriptions.
- Information Extraction: Identify skills, education, certifications, and relevant experience using NLP techniques.
- Feature Representation: Convert resume and job-description text into numerical features using TF-IDF or sentence embeddings.
- Similarity Calculation: Calculate relevance scores using cosine similarity or a transparent, configurable matching formula.
- Resume Ranking: Sort candidate profiles by their job-related relevance scores.
- Results Dashboard: Display rankings, matching skills, and missing requirements for recruiter review.
- Testing and Evaluation: Test the system with different resumes and job descriptions and evaluate the consistency of its rankings.
