Abstract

fetched live from OpenAlex

PolyU has participated in both the two tasks in the TAC 2009 summarization track, including the update summarization task and the automatically evaluating summaries of peers (AESOP) task. The update summarization task is to generate short fluent multi-document summaries of news articles. For each topic, a topic statement and two chronologically ordered newswire document sets are given. The task requires generating a 100-word summary for each document set. The purpose of the AESOP task is to promote research and development of systems that automatically evaluate the quality of summaries. The automatic metrics are run on the data and submitted summarization systems from the update summarization task and compared to manual evaluations. In this year, we mainly study the word-based approaches for both tasks. Simple word-based approaches are first proposed as basic solutions. More sophisticated approaches are then studied by considering the factors beyond words. The systems are detailed in following sections.

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.
