Abstract

fetched live from OpenAlex

This project mainly focused on the patent analysis in the KIND (Knowledge and Innovation Network Data) project, a data repository which links patent data to academic funding data and industrial funding data. In this project, we mainly conducted three sections of work on patent data: topic models and competitor analysis using LDA (Latent Dirichlet Allocation) models, patent classification using GCN (Graph Convolutional Network), and information pathway. The experiments show that LDA is able to identify technology trends in patents and GCN’s performance is great on large patent datasets using citation networks as graphs and BOW (bag of words) vectors as features. GCN performs well with a small portion of training data. We are also able to visualize dynamic information flow through information pathway.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
