How to be best in conveying the message by using NLP approach (Big Five modeling)
summary
Claims that Big Five scores are predictable from short social text and metadata and that models improve from SVM/KNN to deep learning. Pipeline uses word embeddings, convolutional nets, RNNs and CNN experiments then a BERT fine-tune with LIWC/Pennebaker features, and yields usable personality labels for hiring, churn prevention, recommendations and early depression signals. Built iterations and reports good results; one surprising finding is a calculated need for ~24.6 years of full‑time experience to cover all data‑science dimensions.
