Full-Text Section Coverage
loading…Most retrieval systems either carry full text or they don't — they rarely report its internal structure. SciX segments every full-text paper into sections and classifies each heading into one of five canonical roles, which is what powers section-scoped reads and claim extraction. This page shows which roles are populated and how full-text coverage has grown by decade.
Which section roles are populated?
Share of sampled full-text papers carrying at least one section in
each canonical role. Headings are mapped to roles by
scix.section_role.classify_section_role.
Full-text coverage by decade
Papers with full text (blue) vs metadata-only (grey) per decade. The percentage above each bar is the full-text coverage rate for that decade.
