Abstract
Advanced competitive analysis is increasingly becoming important in business analytics. A key component of strategic research is to collect and review information from multiple unstructured sources to identify major competitors and their technology development trends. Topic modeling techniques such as Latent Dirichlet Allocation (LDA) have been applied to competitive analysis, which mainly use the semantic similarities between documents to infer competitive relationships. In this study, we propose using graph embedding methods to learn the implicit competitive relationships between firms. Using patent networks with patents and organizations as nodes, we learn the embeddings of nodes which are then used to cluster organizations into groups. Organizations within the same groups are considered competitors. We applied three graph embedding methods: node2vec, metapath2vec, and GraphSAGE to learn node embeddings. Two of these methods use the structural information in patent networks: node2vec for homogeneous networks and metapath2vec for heterogeneous networks. While, GraphSAGE uses both the structure and content information in the patent network. The results are compared with a baseline author-topic modeling method. The graph embedding methods outperform the author-topic modeling approach in learning the competitive relationships. A case study, examining the evolution of competitors over multiple years, shows the graph embedding method learns meaningful node embeddings.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
