Incorporating Three-dimensional Models And Research On Information Contextual Awareness

Modern scientific research needs more and more scientific devices,whose complexity and scale have reached an unprecedented level.This kind of large scientific project of multi-disciplinary,long period and large collaborative management needs massive 3D model and its technical condition,the traditional digital platform is difficult to provide good support,urgent need for interactive information management and collaboration platform more efficient and more flat,more fusion.In view of the large scientific project of the collaborative development process of multidimensional heterogeneous research information sharing needs effective coordination,using BIM,context awareness,collaborative filtering technology,research and design a 3D model and research of context aware interactive information push service method.The main research contents can be summarized as follows:This paper presents a multi dimension information integration model of 3D digital prototype based on BIM technology.Based on the traditional 4D model,increase development attributes and resource attributes such as multi-dimensional attributes,proposed a three-dimensional digital prototyping multidimensional information integration model based on BIM Technology.The model has a single engineering data source,which can solve the consistency between distributed and heterogeneous engineering and global data sharing,dynamic support in the project lifecycle engineering information creation,management and collaborative sharing.This paper presents a recommendation algorithm based on context awareness of scientific research.Based on the traditional collaborative filtering recommendation algorithm,the research context information associated with the researcher is incorporated into the multidimensional recommendation function of the recommendation algorithm.And propose a recommendation algorithm based on context awareness of scientific research.The algorithm takes full account of the impact of the scientific research situation on the user's information needs,and can more accurately reflect the user's personalized information needs.This paper presents an interactive information display method based on 3D model and context aware.Three-dimensional digital prototyping multidimensional information integration model and based on the research of context aware recommendation algorithm research on information for 3D model and complex device related to massive,heterogeneous data and efficient multi-dimensional collaborative sharing needs,put forward a kind of 3D model and interactive information display method based on context awareness,can be more efficient for image the interactive operation of multidimensional heterogeneous data and information display.
