    p. 135-140International audienceThe selection process of the documents is a very important step in mass digitization projects. This is especially true at the BnF, where the digitization should include or not OCRization depending on the OCR results expected. Consequently, the selection task is very complex and time consuming due to the number of documents to be processed and the diversity of the selection criteria to consider. Trying to improve and simplify this task by automation, we studied the relationship between bibliographic data and the selection decisions of documents. We used two statistical analysis : a factor analysis of correspondence and a multiple correspondence analysis. Our analysis has shown that, for example, the documents in format "4 or GR FOL" and edited "between 1961 and 1990" in Morocco are more likely to be "Selected". However, the documents in format "16 or 8" and edited "between 1871 and 1800 in English or Spanish have a greater chance to be "Not Selected"

    Postal decision fusion based on the Transferable Belief Model

    In order to improve decision-making in automatic recognition of postal addresses, a model for the fusion of postal address recognition systems (or OCR engine, for optical character recognition) based on belief functions theory is exposed. This theoretical framework offers a great flexibility in the representation and combination of the decisions provided by the OCRs, each one being able to provide a complete or a partial postal address. In this article, we describe the chosen frame of discernment, the mass assignment developped from a hierarchical organization of the decisions and the decision-making method. Experimental results show a real improvement of the LAPs’ individual performances.Afin d’améliorer la prise de décision pour la reconnaissance automatique d’adresses postales, un modèle de fusion de décisions de lecteurs d’adresses postales (LAP) basé sur la théorie des fonctions de croyance est exposé. Ce cadre théorique offre une grande flexibilité dans la représentation et la combinaison des décisions fournies par les LAP, chacun pouvant fournir une adresse postale complète ou partielle. Dans cet article, nous détaillons le cadre de discernement choisi, l’affectation des masses basée sur une organisation hiérarchique des décisions, et la méthode de prise de décision adoptée. Les résultats obtenus montrent une réelle amélioration par rapport aux performances individuelles des LAP

    Expanding Tara Oceans Protocols for Underway, Ecosystemic Sampling of the Ocean-Atmosphere Interface During Tara Pacific Expedition (2016–2018)

    Interactions between the ocean and the atmosphere occur at the air-sea interface through the transfer of momentum, heat, gases and particulate matter, and through the impact of the upper-ocean biology on the composition and radiative properties of this boundary layer. The Tara Pacific expedition, launched in May 2016 aboard the schooner Tara, was a 29-month exploration with the dual goals to study the ecology of reef ecosystems along ecological gradients in the Pacific Ocean and to assess inter-island and open ocean surface plankton and neuston community structures. In addition, key atmospheric properties were measured to study links between the two boundary layer properties. A major challenge for the open ocean sampling was the lack of ship-time available for work at "stations". The time constraint led us to develop new underway sampling approaches to optimize physical, chemical, optical, and genomic methods to capture the entire community structure of the surface layers, from viruses to metazoans in their oceanographic and atmospheric physicochemical context. An international scientific consortium was put together to analyze the samples, generate data, and develop datasets in coherence with the existing Tara Oceans database. Beyond adapting the extensive Tara Oceans sampling protocols for high-resolution underway sampling, the key novelties compared to Tara Oceans' global assessment of plankton include the measurement of (i) surface plankton and neuston biogeography and functional diversity; (ii) bioactive trace metals distribution at the ocean surface and metal-dependent ecosystem structures; (iii) marine aerosols, including biological entities; (iv) geography, nature and colonization of microplastic; and (v) high-resolution underway assessment of net community production via equilibrator inlet mass spectrometry. We are committed to share the data collected during this expedition, making it an important resource important resource to address a variety of scientific questions
