Paragraph-level SMART Content tags uncover highly-relevant information not necessarily evident from the title or abstract alone.
Testing Quality: Multipronged QA
1.
Technical Test Set
• Validate the field selection and delivery format
2.
Representative Gold Test
• Establish recall, precision, and harmonic mean versus a manually tagged set of content
3.
Query Set
• Compare product results with expected results from established search queries
4.
Search Logs
• Analyze search logs for candidate terms and noise
5.
Linguistic Intelligence (NLP) Use Cases
