How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Natural language processing (NLP) methods are widely used in search engines, decision-support systems, and many other intelligent applications. One of the essential yet technically demanding tasks in this area is the extraction of triple relations in the form “subject–predicate–object.” Such structures are the basis for knowledge graphs and reasoning, but for languages with limited annotated resources, like Kazakh, this task becomes especially difficult. In our work, we investigate how the use of synthetic data can partially compensate for the lack of linguistic resources. The experimental setup included the generation of additional training data, followed by the training and testing of a model based on the Cross-lingual Language Model – Robustly Optimized BERT Approach (XLMRoBERTa) for triple extraction. XLM-RoBERTa, an improved version of the Bidirectional Encoder Representations from Transformers (BERT) model, benefits from a larger training corpus and increased size. This architecture is effective in cross-linguistic transfer tasks without additional fine-tuning, even between languages with different writing systems. The results show an F1-score of 90.73%. This indicates that even relatively simple augmentation strategies, when combined with advanced models, may considerably improve model performance when working with low-resource languages. The study also suggests that the approach can be extended to other underrepresented languages and integrated into practical systems for information retrieval and knowledge management.
