Abstract
AbstractIn order to activate classroom atmosphere, enhance interaction between teachers and students, and to facilitate teachers to answer questions raised by students in a timely manner, a new real-time barrage class system was designed. To complete overall system design, C/S and B/S mixed-mode and MVC architecture were adopted. Our system is divided into a PC terminal function management module and a mobile terminal function management module. Through TCP protocol, mobile terminal data are communicated with server in form of JSON string. In addition to basic functions of each module, Highcharts technology was used on mobile terminal to realize visual display and analysis function of barrage data. Combined with web crawler technology and the DFA (Deterministic Finite Automaton) algorithm, a sensitive vocabulary filtering function was realized by us. Practice has proved that our real-time barrage class system can strengthen interaction between teachers and students in college classes, stimulate students’ enthusiasm for learning, and improve students’ participation and concentration in teaching process. Therefore, our system has feasibility and promotion value.KeywordsCollege classBarrage systemMixed modeData visualizationDFASensitive word filtering
