## [Introduction] AI Resume Intelligent Screening System: An NLP-Based Automated Recruitment Solution

This open-source project was developed by Samriddhi Singh, based on Python and Flask frameworks, using NLP technologies (such as spaCy NER, TF-IDF, cosine similarity) to implement intelligent resume screening and ranking. The system provides features like a visual dashboard, candidate score comparison, batch upload, real-time search and filtering, and CSV report export. It aims to solve the pain points of time-consuming, labor-intensive, and subjectively biased resume screening for enterprises with large volumes of resumes, helping HR improve recruitment efficiency.

## Project Background and Significance

In the highly competitive job market, corporate recruitment departments face the challenge of screening a large number of resumes. Traditional manual review is time-consuming and labor-intensive, and it's easy to miss excellent candidates due to subjective factors. According to statistics, large enterprises receive an average of hundreds of resumes for a single position, and HR needs to spend a lot of time on initial screening. This project uses NLP and machine learning technologies to intelligently upgrade the recruitment process, freeing HR's energy for interviews and talent evaluation.

## Core Technical Architecture

### Intelligent Entity Extraction
Uses the spaCy NER model to extract key information such as name and email from resumes. If recognition fails, it automatically falls back to regular expressions to ensure the reliability of information extraction.
### Semantic Similarity Matching
Based on TF-IDF vector representation and cosine similarity calculation, it converts job descriptions and resume texts into vectors to quantify the matching degree. Compared to keyword matching, it better understands semantics.
### Interactive Visualization
Integrates Chart.js to render candidate score distribution charts, visually displaying score distributions to help quickly identify high-scoring candidates and outliers.

## Detailed Functional Features

### Batch Drag-and-Drop Upload
Supports batch upload of multiple resumes, file queue management, and allows confirmation and adjustment before analysis, with design considering actual flexibility needs.
### Real-Time Search and Filtering
Client-side real-time search (by name, email, skill tags), and a matching score slider to filter candidates in specific ranges, improving efficiency.
### Dual Theme Design
Provides dark mode (indigo/magenta neon space theme) and light mode, with smooth switching to enhance user experience.
### CSV Report Export
One-click export of CSV reports containing candidate rankings, emails, scores, file names, etc., for easy offline analysis and archiving.

## Technology Stack and Deployment

Technology Stack: Backend Python + Flask; Frontend native HTML/CSS/JS with Chart.js and Lucide Icons.
Deployment Steps: Clone the repository → Install dependencies (`pip install -r requirements.txt`) → Run `python app.py`, and access locally at http://localhost:5000. The architecture is clear and the code is well-organized, facilitating secondary customization.

## Application Scenarios and Value

The system is suitable for:
1. **Campus Recruitment**: Quickly screen resumes of fresh graduates;
2. **Technical Positions**: Semantic matching to identify technical stacks and job requirements;
3. **Headhunting Companies**: Efficiently manage candidate resources and match suitable candidates;
4. **Small and Medium Enterprises**: Compensate for the lack of professional HR and improve recruitment efficiency.

## Summary and Outlook

This project demonstrates the practical application of NLP technology in recruitment scenarios, providing a practical open-source solution with clear code structure and complete documentation. It is a reference case for learning NLP applications and Flask development.
Future expansions can include: supporting more resume formats (e.g., Word), integrating pre-trained models like BERT to improve matching accuracy, adding candidate tracking and history record functions to create a complete recruitment management solution.
