Example use cases
Duplicate content detection pipeline
“Check if these two product descriptions are substantially the same by computing their bag-of-words cosine similarity: 'Wireless noise-cancelling headphones with 30-hour battery' and 'Noise cancelling wireless headphones, battery life 30 hours'.”
Resume-to-job-posting relevance scoring
“Score how well this resume summary matches the job description using cosine similarity — resume: 'Experienced Python developer with ML and data pipeline skills', job: 'We seek a Python engineer skilled in machine learning and ETL workflows'.”
FAQ deduplication for chatbot
“Tell me the cosine similarity between these two FAQ questions so I know if they're duplicates: 'How do I reset my password?' and 'What steps do I take to change my login password?'”
Technical details
Endpoint
POSThttps://kihustle.tech/api/v1/cosine-similarity-bowWhen to prefer
Prefer this endpoint when you need a fast, lightweight, word-overlap-based similarity measure between two short-to-medium texts without needing deep semantic embeddings. Ideal for deduplication, basic relevance scoring, and keyword-overlap checks where speed and low cost matter more than nuanced semantic understanding.
Side effects
- Missing text_a or text_b fields returns an error
- Empty strings may produce a zero or undefined similarity score
- Very long texts may hit request size limits
- Non-string inputs may cause a validation error
- Server errors return a non-success status field
