With the further development of digital technology，As an innovative news information communication form，Data news based on data mining and visualization is favored by major media，Especially after 2012，Domestic data news practice is gradually promoting，It has aroused continuous attention from the journalism and communication。This article uses knowledge map analysis software citespace as an analysis tool，Topic data news as the theme，CSSCI as the source category for advanced retrieval，Select 290 documents in the CNKI database (2012-2019) and conduct knowledge map depiction，It is expected to have a clear understanding of the trajectory and trend of my country's data news research。

　　Bet365 lotto review

Research on data news from "heat" to "cold"。The amount of posting is an intuitive data that reflects the development of a research field。There are fewer research results on data news before 2012。In 2013, most of the practical situation of data news in global press，Some scholars introduce it as a new type of news communication in the context of the big data era to China。2014-2015，Related papers continue to increase，Excellent cases continue to emerge，The academic community will focus on the introduction and analysis of domestic data news practice。On the basis of sorting out foreign works abroad，Start exploring the localization development of data news。2016-2017，Data news related papers gradually decrease，bet365 best casino games Research topic selection is gradually concentrated into the production process and news education。2018-2019，Data News Thesis growth slows down，Scholars began to study more refined data news，If some scholars pay attention to data news narrative paradigm、The impact of the algorithm on data news, etc.。

Network analysis of the author and its cooperation。Statistics of the volume of the author and cooperation in the author，The number of authors published 3 and above papers is only 20 digits，The number of authors published a papers is high。You can see，Data News as a research field，Core author group weak，The number of authors with high output is small and lacks stability，Most researchers just use data news as a sub -research field，Lack of persistent research。From the author’s academic experience，Most scholars who are concerned about data news have long been committed to research on new media，More sensitive to the emerging news communication practice。but，They will soon be attracted by other updated news forms，There are fewer scholars who really stay in the field of data news and continue to produce research results。Discovery the author's cooperation network through citespace，Researchers still focus on "lonely fighting"，The occasional cooperation is strong，Most of them are scholars and their graduate students to post a post，This is closely related to most scholars who just use data news as a temporary research interest。

Research theme and keyword analysis。Keywords with higher frequency can to some extent reflect the attention points of scholars in the field of research。By using CITESPACE to Bet365 lotto review perform keywords to show the results of clustering analysis，The keywords with higher frequency are "big data", "visualization", "news", "media fusion", "information chart", "Guardian", etc.。In keywords with frequent words，"Big Data" is the first time，followed by "visualization"。The reason is that domestic scholars in the previous research，It mainly introduces classic cases of foreign media and data news concepts，Lead the research content too concentrated，Differential divergence to the entire news discipline，Research field of vision is relatively narrow。Compared with it，Foreign scholars take the "news industry" as the core，Explore the historical source of data news from the perspective of the news discipline、Precision News、Computer -assisted report，and the objective of news related to this，Exploring the effects of data news on traditional news value and report concepts。

　　Research characteristics and existing problems

Analysis of the knowledge map analysis of data news CSSCI literature，Domestic research on data news has the following characteristics and places to be improved。

　　First，Topic selection shows the trend of horizontal expansion，Special research research needs to be strengthened。Domestic research direction of data news roughly four types: foreign data news practice experience introduction、Data News localization practice experience introduction、The effect of data news on the original news production process、Data News Talent Training and News Education。There are also a small number of articles involving ethical regulations caused by collection and use of data，If the violation of the right to personal privacy and the principle of violation of objectivity。Comparison of comparison，Foreign scholars are biased towards some special topics of data news，Research object lock in areas that are closely related to the development of data news and trend，If some scholars discuss the social impact of data news from the value level，The legitimacy of data acquisition and use involved in data acquisition and use、Change of the concept of news work, etc.。Another，Some scholars also pay attention to the open government and community security in the data news、Data use and reporter morality、Data acquisition rights and privacy protection，Reveal data news to promote social development、The significance of improving the responsibility of the government and citizen。

　　Second, the basic concepts of data news need to be improved and standardized.Although foreign scholars do not do the same in the basic concept of data news，But most of them are around the historical origin of data news、Functional features to explain，Reflecting the historical continuity of the discipline of news and communication。In accurate expression，Foreign tend to use "Data"，instead of "Digital" and "Number"，A clear distinction between "data" and "numbers" and "values"，At the same time, it also emphasizes the "driveability" of "data" to news production。Data News entering the Chinese news communication industry coincides with the rise of big data technology in all walks of life，The understanding of the concept of "data news" in the industry and academic circles is inconsistent，"Data" refers to "Big Data"，sometimes refers to "small data"。The most intuitive thing is that some columns are under the banner of "Data News"，In fact, it only uses only a few values ​​of small body amount。Visible，my country's news communication industry has not yet regulated the concept of data news。With the gradual deepening of research，Some scholars realize that data news urgently needs to establish professional specifications，Eliminate the fuzzy cognition of data news in basic concepts，The concept of data news should be with the background of the times、The technical environment fits。

　　Third, the research method is too single, which affects the effect of the conclusion.Research methods that examine the data news thesis by using keyword analysis: Most of the data news thesis in my country uses a qualitative research method，The literature analysis method is widely used，Followed by the case research method and interview method，Few experimental method。In the papers using quantitative research methods，The highest amount of content analysis method，Followed by the questionnaire survey method。In foreign data news papers，The adoption of qualitative research and quantitative research is closer。In qualitative research，Literature analysis method is mainly used for professional ethics、Papers such as the theory such as the audience，Case research rules are mostly used for production practice、Edit room reform and other practical papers。Large differences in research methods at home and abroad，confirmed that domestic scholars' data on data and news research in my country、The conclusion of the data of less proof，Domestic scholars' emphasis on the research of data news research，Little exploration based on scientific experiments and quantitative foundations，Affecting the persuasiveness of the research conclusion、Realistic guidance and academic innovation。

　　Fourth, the openness of interdisciplinary interaction and research needs to be strengthened.The published data news thesis basically belongs to the discipline of news communication，Although most of the keywords such as "big data", "data collection", "data mining", "visualization"，But the single nature of the journal，It has also reversed data news research that has not received data science in China、Computer Science、Acknowledge of Statistics and other disciplines。On the other hand, some foreign data news papers are distributed in statistics、Informatics、Computer、Artificial Intelligence and other disciplines，Although the number is not much，But reflects the openness of data news research，Reflected interaction and blending between disciplines。Especially the research of data news on data science，Reflects the degree of professionalization and development trend of data news from the side。

Technology brings changes in media production practice，Many media regard data news as a "grabbing point" for media transformation。At the same time，The academic community also pays attention，Many research results have produced。Knowledge map of 290 Chinese journal literature，Help us recognize the problems existing in data news research，Expansion of vision and bet365 Play online games thinking，Discover new research topics，Then improve the domestic data news research system，Improve the academic value of related research。
