Bonjour à tous, Trois mois après la diffusion du dernier
< Avec Bonjour à tous, Trois mois après la diffusion du dernier bulletin, Géoscopie fait peau neuve et devient « la plateforme d’intelligence économique pour les géosciences » ! En effet, pour mieux servir ses adhérents, le POLE AVENIA a récemment fait l’acquisition d’un outil de veille technologique avancée, IP-Metrix, développé par la société grenobloise TKM. L’outil rassemble les brevets, les publications scientifiques, ainsi que les projets collaboratifs, en plus des seules actualités que traitait l’outil précédent, sur les thématiques du POLE AVENIA. La base de données IP-Metrix/Géoscopie, paramétrée ces trois derniers mois à partir d’une stratégie de recherche basée sur un jeu de plusieurs centaines de mots-clés, contient déjà plus de 6000 entrées sur la seule année 2015. Elle sera mise à jour à une fréquence variable, d’hebdomadaire (actualités) à bimestrielle (brevets, publications) voire semestrielle (projets). Les bulletins Géoscopie « nouvelle formule » contiendront une petite sélection des articles contenus dans la base de données IP-Metrix/Géoscopie, et paraîtront à un rythme bimestriel sous la forme d’un fichier PDF de 8 à 10 pages. Le POLE AVENIA offrira également une large gamme de services d’intelligence technologique et économique à la demande (état de l’art, études de marché, études d’antériorité brevet, cartographie des compétences, etc.), en binôme avec la société TKM qui apportera son savoir-faire en intelligence économique, tandis que le POLE AVENIA apportera la couche métier géosciences. L’équipe du pôle vous invite à découvrir cette première édition du bulletin Géoscopie « nouvelle formule » et à nous faire part de vos retours ou questions par mail en contactant: [email protected]. Bonne lecture !
