Why Traditional Biomarker Databases Fell Short
Legacy biomarker databases had serious limitations that slowed down research. Manual curation created major bottlenecks, with database updates lagging months or years behind new publications. Coverage was patchy because curators couldn't keep up with the exponentially growing volume of biomarker literature.
Search capabilities were stuck with exact keyword matches, missing semantic relationships and contextual biomarker information. Researchers often missed relevant studies because of terminology variations, synonyms, and language differences across different medical fields.
🔍 Traditional Database Challenges:
- Manual Bottlenecks: Human curators could process only 200-300 papers monthly
- Update Delays: 6-18 month lag between publication and database inclusion
- Limited Coverage: Traditional databases struggle with comprehensive biomarker literature indexing, often missing critical cross-disciplinary insights and novel biomarker relationships
- Search Limitations: Traditional keyword-based search approaches often miss relevant studies due to terminology variations and cross-disciplinary biomarker research
