Abstract

fetched live from OpenAlex

Digital news articles are often considered as a primary source of information in today's information-driven society which requires query processing methods to handle the ever-increasing volume of content and various forms of queries. Our goal is to develop a novel approach that can improve the way users access and retrieve news by considering Natural Language Processing (NLP)-driven query processing for news articles. This will address the complexities of news articles written in multiple languages and covering a range of topics. The proposed method helps in enhancing the performance of query processing in applications such as journalism, academic research, and content suggestion. By conducting experiments with Sentence Embeddings, Large Language Model (LLM), and Approximate Nearest Neighbours (ANN), this thesis improves news article search systems. Results show that the method improves the quality of the search results for the queries to return more accurate and relevant search results across different languages.

Full frame distilled prediction

Teacher imitation

Not 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.
