Latent Personality Traits Assessment From Social Network Activity Using Contextual Language Embedding
Bibliographic record
Abstract
Recognizing author identity from digital footprints without having a large corpus of documents from an individual is of keen interest to security researchers and government agencies. Users reveal aspects of their personality via the content they share with their social media followers and through the patterns in their interactions on online networking platforms. This study examines the potency of emerging natural language processing (NLP) methods in analyzing social network activity. A linguostylistic personality traits assessment (LPTA) system is developed to estimate Twitter users’ personality traits based on their tweets using the Myers-Briggs-type indicator (MBTI) and big-five personality scales. A novel input representation mechanism is proposed to process tweets by converting them into real-valued vectors using frequency, co-occurrence, and context (FCC) measures. Other prevalent text representation schemes, such as one-hot encoding, count-based vectorization, and pretrained language model representations are used as comparators. A genetic algorithm (GA) approach is proposed to reduce the feature set and increase the efficacy of the features extracted. The developed system outperforms the state-of-the-art research by reliably estimating the user’s latent personality traits while using 50 or fewer tweets per user.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
