Research on the application of information visualization in news communication



With the rapid progress of science and technology, people receive information from the past real scene information to the current picture information, gradually realizing the information visualization in the era of big data. Therefore, more visual methods such as sound and video are used in the process of news communication to provide audiences with more detailed news events and make them easy to receive the connotation and essence of news. As people's pace of life gradually accelerates and the fast development of fast food culture, people are more willing to receive visual news.

Visualization is the theory, method, and technique of using computer graphics and image processing techniques to convert data into graphics or images that are displayed on the screen for interactive processing. In the 1990s, the computer operation interface developed from the programmed operation of text data to the visual operation of graphical interface, which made the computer develop from the professional application for elite groups to the popular application for the public. Visualization technology transforms complicated and abstruse operation language into simple and intuitive graphical interface to interact with people. People can grasp the connotation of abstract concepts through visual senses. Visualization technology not only strengthens human cognitive ability, but also drives further research on information visualization. Information visualization is the use of computer graphics and data mining technology and methods to hide information in the data in an interactive way vividly displayed to the user. Information visualization is based on the information data of large, complex and abstract characteristics, in order to reduce the audience to digest cost information of the self, the information system structure, the essential connotation and objective law of mining, and finally the use of graphics intuitive form, to achieve the purpose of instant transfer large data, to achieve the effect of information be clear at a glance.

News reports in traditional media are based on objective facts. Traditional journalism requires a comprehensive narrative of news facts to be presented to the audience. No matter it is a news event or a news space, every detail of news facts should be truly reflected to the audience. Traditional news is targeted at complex news information. In the process of news production, a lot of manpower and material resources are needed and a lot of time is spent. For audiences, they will also encounter obstacles to receive news.

The application of information visualization in news communication greatly solves the difficulty of traditional news communication. Information visualization presents the results of news facts to the audience through technical means, which is a seemingly revolutionary change to the dissemination of news. Some Suggestions on the application of information visualization in news communication are put forward.

(1) it is conducive to sorting out news clues and building structural framework

The application of information visualization in news communication can dissolve the tedious and lengthy text narration of traditional news communication, so that the audience can deconstruct news information with visual information and more easily absorb news information. At the same time, information visualization can sort out news facts, deconstruct news information, and connect the node contents of news facts through sound and animation, so as to build a complete news framework. Visualization methods such as relational flow chart, narrative illustration, tree structure diagram, timeline and spatial diagram are commonly used to realize the connection of news fact nodes, and information visualization enables the author to grasp the information content of news facts and grasp the connotation and essence of news facts very quickly.

(2) create news situations and let the audience take the initiative to participate

With the advent of the information age, the basic mode of news communication has been completely changed, and news has been presented to the audience in various forms. However, news dissemination is still a kind of indoctrination of information, without the active participation of the audience in the dissemination of news information. However, information visualization can bring about a qualitative leap in news communication and make the passive acceptance of news audiences become active participation. Firstly, information visualization can make news facts story-like and contextualized, and reflect news information in detail and truthfully. The we-media service number "mixed days" in WeChat public platform is a successful case of information visualization application. It gets a lot of attention by creating contextual, story-like content.

I think data visualization is not simply about turning data into charts. It's about looking at the world through data. In other words, the object of data visualization is data, but what we want is actually -- data vision, data as a tool, visualization as a means to describe reality and explore the world. Data visualization aims to convey and communicate information clearly and effectively by means of graphics. But that doesn't mean that data visualization must be tedious to achieve its functional purpose, or extremely complex to look colorful. In order to effectively convey ideas and concepts, aesthetic form and function need to go hand in hand and achieve deep insight into relatively sparse and complex data sets by visually conveying key aspects and features. However, designers often fail to strike a good balance between design and function, thus creating flashy data visualizations that don't serve their main purpose. First, data visualization is the evolution

Data visualization mainly relies on graphical means to convey and communicate information clearly and effectively. But that doesn't mean that data visualization must be tedious to achieve its functional purpose, or extremely complex to look colorful. In order to effectively convey ideas and concepts, aesthetic form and function need to go hand in hand and achieve deep insight into relatively sparse and complex data sets by visually conveying key aspects and features. However, designers often fail to strike a good balance between design and function, thus creating gaudy forms of data visualization that fail to achieve their main purpose, i.e. to convey and communicate information. Data visualization is closely related to information graphics, information visualization, scientific visualization and statistical graphics. Currently, data visualization is a very active and critical aspect in research, teaching and development. The term "data visualization" achieves the uni

MALOFIEJ 20 "We have lost some of our finest sons and daughters in the fight against terrorism, The best way to honor these fallen is to see this mission through, and to lay the foundations for peace by promoting freedom. From the beginning of 2003 to the end of 2011, the nearly nine-year war in Iraq can be divided into two stages, namely the early stage of a brief large-scale operation phase and the middle and late stage of a long stable operation phase. Former U.S. defense secretary Donald rumsfeld has said that the main goals of the war in Iraq include removing saddam hussein's dictatorship and helping the Iraqi people build a free and democratic regime. The second is to search for and destroy weapons of mass destruction hidden in Iraq and eliminate terrorists. Third, ending dictatorship and providing humanitarian assistance; Fourth, protect Iraqi oil and other natural resources.
