Modeling and Comparing the Influence of Neighbors on the Behavior of Users in Social and Similarity Networks
Bibliographic record
Abstract
Social networks are becoming more and more popular with the advent of numerous online social networking services. In this paper, we explore social rating networks, which record not only social relations but also user ratings for items. We analyze and model the effects of social influence and correlational influence in such networks, based on influence coefficients that measure the degree of influence in a network. We distinguish two types of user behavior: adopting an item and adopting a rating value for that item. We propose models to analyze and measure the influence of neighbors on both item and rating adoption behavior of users. Our experiments demonstrate that social influence has a much stronger impact on user behavior than correlational influence. Social and correlational influence are global effects in the entire network. However, there are local differences, i.e. certain users have a stronger social influence than others. To model this effect, we introduce the novel concept of social authority of individual users. We also propose an objective way to evaluate the social authority measure by injecting it into a simple recommender system.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
