Classification method

The corpus is not created by treating the OpenAlex Philosophy subfield as a hard inclusion criterion.

The V3.1 pipeline combines evidence from:

• OpenAlex concepts
• non-duplicated keyword evidence
• philosophical ontology terms
• philosopher-name evidence
• title evidence
• abstract evidence where available
• document-role detection
• conservative handling of ambiguous uses of concepts such as Phenomenology

Classification tiers:

• CORE
• PROBABLE
• BORDERLINE
• EXCLUDE

Document roles:

• SCHOLARLY
• EMPIRICAL_ADJACENT
• REVIEW
• LOW_QUALITY
• PARATEXT

The classification is heuristic and is not intended to represent a human-reviewed disciplinary ground truth.
