Analyzing The Consistence And Diversity Of Reporting Tone Of International News Based On Mass Media Data

Along with the internet unceasing development,the era of big data has arrived.And the amount of information in human society exponentially grows.Media always records the occurring events all over the world.Nowadays,the mass media data,Global Database of Events,Location,and Tone,provide reliable data support for research.More and more people accept that it is great promise to analyze big data by the theory and analysis method of complexity science.In this paper,we first compare the reporting subjects,event types and tone among 9 countries which are differ quite a lot in potential ideology.And we find even though these countries have different preference on event type,they all tend to pay more attention to the Great Power and their neighboring countries.Moreover,they show convergence in reporting tone when covering international news coverage.The former reflects that the news value is generally accepted and practiced by countries,and the convergence in tone reflects the fact that reporters are not overly influenced by their respective ideology;rather they share to a large degree some common or similar values when covering international news.we compare the tone of international news among over 75 countries and use entropy and Hurst parameter to depict the stability of daily average tone.We find a strong negative correlation between Gross Domestic Product and entropy of countries' daily average tone.Another negative correlation could be found between entropy and Hurst parameter.Countries with higher degree of economic development have less variability,stronger long-range correlation,and hence,more consistency in their tone of reporting international news.
