Conceptual Graphs (CGs) are a knowledge representation language based on the existential graphs of Ch. S. Peirce and the semantic networks of Artificial Intelligence. CGs are also a modeling and design language, which is human readable and computer tractable. This makes CGs suitable for a large variety of applications. The novelty of this paper, is a new approach to XML data modeling based on Conceptual...
The existed cloud data models cannot well meet the management requirements of structured data including a great deal of relational data, therefore a two-layer cloud data model is proposed by referencing the relation data model, Hierarchical data model and key value data model. In the representation layer, the concepts of composite class and composite object are proposed to represent nested data structure...
In the era of big data, data analytics, business intelligence database management plays a vital role from technical business management and research point of view. Over many decades, database management has been a topic of active research. There are different type of database management system have been proposed over a period of time but Relational Database Management System (RDBMS) is the one which...
Knowledge sharing, which is the basis for forming a knowledge application group, allows knowledge workers in an enterprise such as knowledge salespeople, knowledge operators, knowledge directors or knowledge managers to share the knowledge of other people or of other parts of the system to solve their problems in work. So knowledge sharing is an important part of knowledge management. In this article,...
Query tools that depend on the ability of programmers, impose a cognitive load that could reduce the user's productivity. Within MDD, the proposal of our work is the creation of a visual query mechanism derived from a historical multidimensional data structure. This mechanism facilitates (and partially automates) the formulation of temporal and decision making queries.
Data Integration refers to the problem of combining data residing at homogeneous, autonomous, and heterogeneous data sources, and providing users with a unified global schema. Users pose their queries in terms of this unified global schema. Data integration system allows users to perceive the entire collection as a single source, query it transparently, and receive a single and unambiguous answer...
Natural environment modeling and simulation is a hotspot in M&S field. Atmosphere environment simulation is an important part of synthetic natural environment modeling and simulation. In military training and weapon manufacturing, it is very important to promote simulation fidelity via combining the atmosphere environment simulation with traditional simulation systems. This paper studies the atmosphere...
This paper gives a detailed description of the database construction for LHI image dataset. LHI image dataset is an integration of many desired annotated tasks in an all-in-all labeling frame work, such as segmentation, sketch, and hierarchical decomposition, employing the And-Or graph grammar. A two-tier database is designed to manage large amount of various data and And-Or graph model, togethere...
