CORTEX: High-Quality Cross-Domain Organization of Web-Scale Corpora through Ontological Corpus Graph

arXiv:2606.30175v1 Announce Type: new Abstract: The continuous evolution of large language models drives escalating demands on data scale and quality, and as different training stages impose increasingly tailored data requirements, systematic organization of high-quality corpora becomes indispensable. Existing corpus construction pipelines confine the resulting corpora to flat, undifferentiated document collections, universally lacking systematic knowledge organization. We present Cortex, to our knowledge the first framework that elevates web-scale corpus construction from flat document filter

Why this matters
Why now

The continuous evolution of large language models is driving escalating demands for higher quality, systematically organized web-scale data, which current corpus construction methods fail to provide.

Why it’s important

Improved data organization and quality, as proposed by Cortex, directly addresses a critical bottleneck for advanced AI model training, potentially accelerating AI development and performance significantly.

What changes

The paradigm for constructing and organizing web-scale corpora would shift from flat, undifferentiated collections to structured, knowledge-based systems, enhancing training data utility and efficiency.
