Abstract
The phenomenon of big data is described using five Vs: Volume, Variety, Velocity, Variability and Veracity. In this paper, we are interested by analyzing and pre-processing tweets for NLP and machine learning applications such as machine translation and classification. Collected contents from Twitter (tweets) are considered as unstructured, highly noisy and short (140 characters) texts. Overcoming these complex challenges will help learn from such data and apply traditional NLP and machine learning techniques. In this paper, we propose a pre-processing pipeline for tweets consisting of filtering part-of-speech, named entities recognition, hashtag segmentation and disambiguation. Our proposed approach is also based on the graph theory and group words of tweets using semantic relations of WordNet and the idea of connected components. Evaluations on the task of classification showed promising results when using this proposed preprocessing pipeline, with an increase in the accuracy of the classification up to 87.6%.

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 it
