We introduce MinerU2.5, a 1.2B-parameter document parsing vision-language model that achieves state-of-the-art recognition accuracy while maintaining exceptional computational efficiency. Our approach employs a coarse-to-fine, two-stage parsing strategy that decouples global layout analysis from local content recognition. In the first stage, the model performs efficient layout analysis on downsampled images to identify structural elements, circumventing the computational overhead of processing high-resolution inputs. In the second stage, guided by the global layout, it performs targeted content recognition on native-resolution crops extracted from the original image, preserving fine-grained details in dense text, complex formulas, and tables. To support this strategy, we developed a comprehensive data engine that generates diverse, large-scale training corpora for both pretraining and fine-tuning. Ultimately, MinerU2.5 demonstrates strong document parsing ability, achieving state-of-the-art performance on multiple benchmarks, surpassing both general-purpose and domain-specific models across various recognition tasks, while maintaining significantly lower computational overhead.

We applied text classification methods on a corpus of product reviews we created with the help of a questionnaire. We found that for certain values, “traditional” deep neural networks like CNN can give promising results compared to the baseline. We propose some ideas to improve the results in the future. The bilingual corpus we created which contains more than 16 000 consumer reviews associated to the human value profile of the authors can be used for different marketing purposes.

La détection des valeurs humaines dans le texte est une tâche qui intéresse les industriels dans la mesure où elles complèten t le profil des consommateurs. Cette détection nécessite des outils et des méthodes issues du traitement automatique des langues (TAL) et s’appuie sur un modèle psychologique. Il n’existe que très peu de travaux, alliant modèles psychologiques de valeurs humaines et extraction de leur réalisation linguistique sur les réseaux sociaux à l’aide du TAL. Dans cet article, après avoir défin i le modèle des valeurs de Schwartz que nous utilisons ainsi que le corpus en cours de construction pour le domaine de la parfumerie, nous proposons quelques pistes de réflexion possibles pour la construction de technologies permettant de relier des marqueurs textuels à des valeurs humaines.
