News Data Analysis System Based on UML and Computer Aided Technology

From the perspective of big data, making full use of data information in news reports is like adding an innovative news value to general topics. When mining exclusive news, the participation of big data makes the competition among peers shine. In daily work, traditional journalists have many difficulties in searching for news clues and finding news topics, but the large-scale open-source data has given media staff a new dawn, which can be described as a new way. This paper studies the design of news data analysis (NDA) system based on UML. This paper briefly discusses the necessity of NDA and UML model, and analyzes the design of NDA system and system function design based on UML computer-aided technology; The algorithm of news event data analysis is proposed. Through the test of the accuracy and coverage of NDA in different fields, the effectiveness and feasibility of the NDA system based on UML computer-aided technology proposed in this paper are verified.
