Application of data modeling in the Internet of Things

With the further development of big data and artificial intelligence, the Internet of Things is increasingly developing in the direction of AIOT. The Internet of Things infrastructure will become a new generation of information infrastructure, forming a trinity of "Internet of Things", "Digital Internet" and "Intelligent Internet" architecture.

The collection, storage, analysis, mining and intelligent application of IoT infrastructure data is a very important part. To this end, we need to systematically model IoT data and establish a complete and standard IoT data modeling system to provide basic guarantees. In this way, we can better analyze, mine and apply IoT data and further promote the development of IoT.

The object model aims to standardize and semantically describe, identify and manage objects, and promote the intelligence and efficiency of the Internet of Things.

IoT ontology modeling:

• Purpose: To solve the problem of "what is an object", that is, to define and describe objects in the Internet of Things.
• Method: Standardized summary and organization of IoT infrastructure and data. Form a complete set of data catalogs (metadata) to provide the basis and framework for objects.
• Achievements: Construct an ontology model suitable for IoT infrastructure service scenarios. This model can describe the object's basic properties, functions, and relationships with other objects.

IoT analysis system:

• Purpose: To solve the problem of object access and discovery, that is, how to identify newly connected objects.
• Method: Object recognition is achieved by analyzing the core elements of the object, such as its name, ability and location. This includes object name identification analysis, capability identification analysis, location identification analysis, etc.
• Achievements: Provide an object analysis system that can quickly identify and discover newly accessed objects and provide corresponding services and management.

Object enabling system:

• Purpose: To solve the problem of "how to use objects", that is, how to manage and integrate objects so that they can provide services to the outside world.
• Method: Responsible for the access management, capability management and capability integration management of objects to ensure that objects can be used correctly and effectively.
• Achievements: Provide a unified interface and capability services so that external systems or applications can easily use and manage objects in the Internet of Things.

The principles and methods of mathematics and statistics that need to be mastered for data analysis and modeling include but are not limited to:

• Calculus: Calculus studies the changing rules of functions In data analysis, the application of calculus mainly involves derivatives and differentials, which can be used to study the changing trends of data points.
• Linear algebra: Linear algebra is a discipline that studies vectors, matrices and their operations. In data analysis, the application of linear algebra mainly involves vectors, matrices and linear regression.
• Probability theory: Probability theory is the study of the probability of random events and its statistical rules. In data analysis, the application of probability theory mainly involves probability distribution and hypothesis testing.
• Statistics: Statistics is a discipline that studies the collection, organization, description, analysis and interpretation of data. In data analysis, the application of statistics mainly involves descriptive statistics, inferential statistics and data mining.
• Machine learning: Machine learning uses algorithms to allow machines to learn knowledge from data. In data analysis, the applications of machine learning mainly involve classification, regression, clustering, etc.
• Deep learning: Deep learning is a branch of machine learning, which mainly learns by building deep neural networks. In data analysis, the application of deep learning mainly involves image recognition, speech recognition, and natural language processing. wait.
• Data visualization: Data visualization is the presentation of data through charts, graphs, etc., in order to better understand and analyze the data.

The practice of data analysis and modeling based on the Internet of Things, based on artificial intelligence, can use the following methods and technologies:

• Data collection and processing: Use artificial intelligence technology to collect data generated by IoT devices in real time, process and analyze it. This includes steps such as data filtering, cleaning, and preprocessing to extract valuable information.
• Feature extraction and selection: Use artificial intelligence algorithms to automatically extract meaningful features from raw data. This can be achieved through techniques such as feature engineering and machine learning to better utilize the data.
• Model training and optimization: Use artificial intelligence technology to train and optimize the model. This can employ various machine learning algorithms and deep learning techniques such as decision trees, support vector machines, neural networks, etc. Through training and optimization, the prediction accuracy and stability of the model can be improved.
• Real-time prediction and decision-making: Use artificial intelligence technology to conduct real-time analysis and prediction of real-time data. This can be achieved through technologies such as streaming computing and real-time machine learning to detect anomalies in a timely manner and take appropriate measures.
• Visualization and interaction: Use artificial intelligence technology to visually display analysis results and provide users with a friendly interactive interface. This can be achieved through data visualization technology, natural language processing and other technologies, allowing users to better understand data and device status.
