A New Machine Learning Framework for Effective Evaluation of English Education

With the rapid development of information technology, English education has attracted the interest of scholars for its ability to rely on computers to analyze and understand human language. Taking machine learning (ML) as the core, this paper tries to develop an evaluation system for ML-based English education. Specifically, a basic ML model was established with four stages: environment, knowledge base, learning process, and implementation process. The entire ML system was divided from top to bottom into a user layer, a business layer, and a data layer. Application results show that, during the ML, even users with similar personal data and the same goal have vastly different suitable learning materials, due to their gap in personal capabilities. The research provides an effective way to evaluate English education in the context of computer science and artificial intelligence.

DESIGN AND IMPLEMENTATION OF PIG INTELLIGENT CLASSIFICATION MONITORING SYSTEM BASED ON CONVOLUTION NEURAL NETWORK (CNN)

With the development of agricultural information technology, the intelligent monitoring system applied in pigsty can alert people when domestic pigs and wild boars jump into each other's pigsty, and bring convenience to breeding staff. The system uses convolution neural network as the core algorithm to realize the function of real-time monitoring and reminding users. Using Spring MVC framework technology, a pig intelligent classification monitoring system based on C/S architecture is developed. Three layer architecture model of presentation layer, business layer and persistence layer is used. Neural network algorithm is embedded in the image processing module, and Netty framework is used to maintain the connection between each module. Field experiments show that the recognition accuracy of the system can reach 97.08%. This system can be used as a reference for the design of pig intelligent classification monitoring system, and provide a reference for the design of related systems.

Emerging Applications of Blockchain Technology on a Virtual Platform for English Teaching and Learning

To extend a broad application of blockchain technology to the fields of online English education, this paper aims to improve a virtual platform for English teaching and learning of landscape design majors, mainly composed of presentation layer, business layer, and data layer by analyzing the performance of the proposed algorithm, and comparing with other existing algorithms. In the platform, through the service layer, the communication between the presentation layer and the data layer is completed, and the data in the data layer is transferred to the presentation layer. The user first establishes a connection with the server in the presentation layer. Using the transmitted data information, the server assigns an identifier to the user and establishes a role model. Users can download the teaching courseware through the server and simulate the real learning scene by controlling the interaction of XAML files. The results show that the virtual teaching platform makes the interconnection of users (students and teachers), machines, and things at any time and any place; realizes information self-verification, transmission, deep unsupervised learning, and management; and gives students a more realistic visual experience in high security.

A Novel Tool for Configurable Process Evolution and Service Derivation

In recent years, variability management in business processes is considered a key of reuse. Research works in this field focused mainly on variability modeling and resolution; whereas, evolution has been somehow neglected. In fact, new business requirements may occur, and business processes must evolve in order to meet the new needs. Furthermore, the evolution at business layer represented by configurable processes impact the IT layer represented by services. In this case, it is necessary to synchronize the changes between these two layers. In other words, the alignment of configurable processes and configurable services must occur to maintain an integrated view of an organization. This can be reached by the concept of service-based configurable processes. The study of existing tools in this domain shows the lack of solutions integrating both the evolution management, and the change propagation with respect to the variability. This article aims to represent the CPMEv, a novel tool for evolution management of service-based configurable processes.

Database Connection Technologies from JSP Pages and Java Web Application Servlets

The purpose of the study is to demonstrate the diversity of solutions on the issue of connecting to a database, including a description of the developed connection controller class, as well as various ways to create connection pools on a web server and application servers. The article discusses the practical issues of using JDBC technology when building a Java web application. In the examples, the presentation and business layer of the application are developed using JSP-pages and servlets, the database operates on the MySQL platform. The described methods for creating and configuring a connection pool are shown on the example of the ApacheTomcat web server and the GlassFish application server. The question of optimizing database connections in Java applications remains open, despite the diversity of solutions. The study examines and proposes methods for constructing classes of connectors, various methods for creating pool connections, and describes the results of solving problems arising from the implementation of the described techniques. A detailed classification of ways to connect to the database is given.
