Abstract

fetched live from OpenAlex

Automatic building of social networks requires extracting pair-wise relations of the individuals. In this paper, supervised learning of social networks from a set of documents is proposed. Given a small subset of relations between the individuals, the problem of learning social network is translated into a text classification problem. Relation between each pair of individuals is represented by a vector of words produced from merging all documents associated with these two individuals. The known relation is used as a label for the relation vector. The merged documents and their given labels, are used as training data. By this transformation, a text classifier such as SVM can be used for learning the unknown relations. We show that there is a link between the intrinsic sparsity of social networks and class distribution imbalance of the training data. In order to re-balance the unbalanced training data, a multiple resampling method, including undersampling of the majority and oversampling of the minority class, is employed. The proposed framework is applied to a Friend Of A Friend (FOAF) data set and evaluated by the macro-averaged F-measure.

Full frame distilled prediction

Teacher imitation

Not 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.
