Problem

Many ranking and recommendation workflows rely too heavily on exact keyword overlap, even when two records express the same concepts using different language.

Approach

• Extracted domain-relevant entities, terms, and text signals with NLP pipelines
• Computed semantic alignment using transformer embeddings and vector-similarity methods
• Combined semantic similarity with scoring and ranking logic for more useful matches
• Added explainable missing-signal or gap feedback to make ranking results more actionable

Results

• Produced more informative semantic matching than keyword overlap alone
• Created a reusable ranking pipeline applicable to recruitment, semantic search, recommendations, and record matching
• Added explainable feedback that helps users understand why items rank highly or where important information is missing
