Technical Architecture & Execution Mechanics
TF-IDF Vector Space Modeling for Resume Semantic Relevance
ATS algorithms score candidate suitability using Term Frequency-Inverse Document Frequency (TF-IDF) and Cosine Similarity across vector spaces. By vectorizing the job description tokens and candidate resume tokens into sparse n-gram frequency matrices, the system computes the directional cosine angle theta between candidate profiles and hiring requirements.
ATS_Score = Cosine_Similarity(A, B) = (A . B) / (||A|| * ||B||) * 100Technical Limitations & Operational Constraints
- PDF formatting artifacts (such as complex two-column tables) should be pasted as plain text for accurate keyword extraction.
