在互联网时代,对地方志文本进行可视化是方志数字化建设的一个重要部分,可以满足用户对历史文化知识服务多样化、个性化的需求。以我国地方志语料库中的文本为研究对象,采用文本可视化理念对地方志文本进行处理,一方面需要对地方志内容进行专题分类,并以时间-事件维度为主导将各种地方志中记载的事件结合具体描述信息通过WebGIS呈现出来;另一方面,还需通过知识地图展现事件之间的逻辑关系和知识网络,方便用户在观看知识地图的同时完成对知识的内化过程。通过案例研究,得到基于大量地方志文本的人物事件关系图谱,实现地方志文本可视化应用模式创新的一次初步尝试。图3。参考文献12。 相似文献

对于纸媒而言,新闻的可视化阅读由来已久.一般来说,照片就是新闻事件的可视化呈现,漫画则是新闻评论的可视化呈现.在如今轻阅读、碎片化阅读、移动阅读的时代,图表脱颖而出,成了数据新闻的可视化呈现.
数据新闻是一种新兴的新闻生产方式,它是在互联网特别是移动互联、大数据、云计算等新兴技术诞生、爆发之时,所催生的新闻信息整理和挖掘模式.在传统媒体时代,记者第一时间到达现场报道新闻事件.而随着自媒体的兴起,报道新闻事件越来越不是记者的专利,而揭露事件背后的本质,才是专业新闻记者擅长的事情.所以也有观点说,数据新闻将是未来职业记者的转型方向. 相似文献

现代传播理念认为,新闻传播的最大魅力在于新闻的即时性。对电视而言,最大的魅力又集中体现在直播新闻上,而电视直播新闻最重要、最深远的意义就在于它可以把观众带到新闻现场,让他们目击新闻事件的发生状况和演变过程。随着电视技术的飞速发展,数字技术、卫星新闻采集技术的大量应用,电视直播技术越来越成熟, 相似文献

“直播”,也即“现场报道”,是记者在新闻事件发生的现场,直接对新闻事件以口头方式进行报道。这种时间和空间的特殊性．要求现场直播的新闻记者必须具备清晰流畅的口语表达能力,对新闻有较好的洞察分析、驾驭现场的能力,以及最基本的政治素养。 相似文献

Content analysis of news stories is a cornerstone of the communication studies field. However, much research is conducted at the level of individual news articles, despite the fact that news events are frequently presented as “stories” by news outlets: chains of connected articles offering follow up reporting as new facts emerge or covering the same event from different angles. These stories are theoretically highly important; they also create measurement issues for general quantitative studies of news output. Yet, thus far, the field has lacked an efficient method for detecting groups of articles which form stories in a way that enables their analysis. In this work, we present a novel, automated method for identifying news stories from within a corpus of articles, which makes use of techniques drawn from the fields of information retrieval and network analysis. We demonstrate the application of the method to a corpus of almost 40,000 news articles, and show that it can effectively identify valid story chains within the corpus. We use the results to make observations about the prevalence and dynamics of stories within the UK news media, showing that more than 50% of news production takes place within the form of story chains. 相似文献

This study presents the IDEA (internalization, distribution, explanation, action) model as an easy-to-use and situationally generalizable framework for quickly developing effective messages instructing people on how to protect themselves before and during high-risk events, crises, disasters, and other emergencies. The model consists of four elements: helping message recipients internalize the potential impact of the risk or crisis event, identifying appropriate channels and strategies for distributing the risk or crisis event messages, offering a brief and intelligible explanation of the nature of the risk or crisis, and providing specific self-protective action steps for people to take. The model may be used to design messages in any risk, crisis, or emergency context. Through a posttest-only quasi-experimental cross-sectional research experiment, this study measured the perceived message effectiveness, cognitive understanding, and behavioral intentions of those viewing a television news story about a crisis situation employing the IDEA model compared to those viewing a similar story replicating typical crisis event news stories delivered to general publics. This comparative examination revealed that the message designed according to the IDEA model was significantly more effective than the status quo message and resulted in greater behavioral intentions to engage in appropriate self-protective actions in the event of an acute risk or crisis situation. Strategies for implementing the model are also provided. 相似文献

The recent proliferation of online videos captured at the scene of news events begs the question: Do news videos have a meaningful impact on citizens’ political opinions and behaviors that is different than that of news articles? This was examined in an experiment using carefully matched videos and articles about the European refugee crisis. Findings show that articles generated stronger intentions to help refugees than videos, and this was mediated by the depth with which the news story was processed. Despite their increasing prominence and intuitively impactful qualities, news videos do not deliver more powerful effects than news articles. 相似文献

An experiment (N = 272) demonstrated that disagreement—either civil or uncivil—may have a chilling effect on the public discourse vital to a deliberative democracy. Both forms of disagreement—in comments posted on a news story about abortion—caused negative emotion and aggressive intentions. However, only uncivil disagreement led people to respond back uncivilly and indirectly led to greater intention to participate politically, if it aroused aggressive feelings. Findings support extending face and politeness theories to the computer-mediated space of online commenting. Results are discussed in relation to the impact on the public discourse. 相似文献

Being able to probive live coverage of breaking news events is one of the unparalleled strengths of television. The purpose of this study is to assess the opinions of 18–24 year olds about live television news reporting. Variables identified by respondents are characterized in one of three ways: awareness of live reporting; positive aspects of live reporting; and negative aspects of live reporting. From the more than 500 young adults surveyed, findings show most do not base their viewing habits on how often a news operation goes live or whether that operation happens to be first to hit the air with breaking news. Respondents show strong agreement that live reporting gives the story a sense of immediacy, leading the positive attributes of live reporting. However, leading the list of negative attributes is the criticism that there are times when a live report is meaningless. There were differences in resoonses based on the market in which the respondents reside. 相似文献
