Proprietary NLP Models
Explore the mathematical frameworks, spectral algorithms, and neural architectures powering NLPinSEO's semantic audits.
TDFM
Status: AvailableText Density Functional Model.
Density-based semantic ranking inspired by Density Functional Theory. Measures information concentration, semantic density gradients, and local semantic potential fields across text layouts.
SGF
Status: In DevelopmentSpectral Green Functions.
Graph spectral model for semantic structure and document quality analysis. Models semantic connectivity via Green's functions on document graph representations, capturing long-range coherence.
TDFM-SGF
Status: In DevelopmentHybrid Architecture.
A hybrid framework combining the continuous semantic density field calculations of TDFM with the topological connectivity mapping of SGF. Designed for next-generation semantic search intelligence.
