Abstract

fetched live from OpenAlex

Automatic text summarization is one of the important tasks in NLP. Knowledge graph can improve the quality of summary by building the relationship between entities from source document. However, existing studies introducing knowledge graph have the problem of poor coordination between text content and knowledge bases. In our work, we raise a new model, ATMG, which combines feature matrix obtained from the external knowledge with original text classification label and context to allocate the attention weight. ATMG integrates external knowledge embedding into global semantic information, and chooses the appropriate knowledge graph to match different document backgrounds. In this way, the accuracy of lexical entity relationship construction can be improved so that the quality of summaries can be enhanced. A lot of experiments show that our model outperforms in different degrees compared to the traditional models, and the ablation experiments demonstrate the effectiveness of each module of ATMG.

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.
