Abstract

fetched live from OpenAlex

The aim of this research is to show how social networks can be used for marketing purposes. This is implemented with the assistance of learning algorithms. The method proposed in this research is based on the analysis of “Support Vector Machines”, which facilitates analysis of all information gathered from the social websites. It differs from other methods currently being used by social networking websites, which do not take advantage of classification. By using public information from social networks, a dataset was formed. It comprised of a thousand users and seven features. The examined features were location, age, gender, occupation, relationship status, and average travel time/year. In this research, the dataset will be examined twice: first using a regular SVM; and next by using “Weighted Feature Support Vector Machines”. For the latter, to assign weights, a method called “Pairwise Comparison” will be used to rank the importance of features.

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.
