In this paper we propose an integration of a selforganizing map and semantic networks from WordNet for a text classification task using the new Reuters news corpus. This neural model is based on significance vectors and benefits from the presentation of document clusters. The Hypernym relation in WordNet supplements the neural model in classification. We also analyse the relationships of news h...

As more people prefer to read news on-line, the newspapers are focusing on personalized news presentation. In this study, we investigate the prediction of article’s position based on the analysis of article’s content using different text analytics methods. The evaluation is performed in 4 main scenarios using articles from different time frames. The result of the analysis shows that the article...

What is the information content of news-based measures of sentiment? How are they related to aggregate economic fluctuations? I construct a sentiment index by measuring the net amount of positive expressions in the corpus of Economic news articles produced by Reuters over the period 1987 2013 and across 12 countries. The index successfully tracks fluctuations in Gross Domestic Product (GDP) at ...

This research examined media depiction of homicide in a large metropolitan area from the market-driven journalism perspective (McManus, 1994). From this perspective, news organization decisions are based on journalist and news editor perceptions of what type of stories resonate with the general public. Accordingly, the news production process becomes characterized as an exercise in market strat...

This paper estimates the effect of presentation of information on financial markets, using a natural experiment in prominent “front page” positioning of news on the Bloomberg terminal. The front page and non-front page articles are indistinguishable by either algorithmic analysis or by the target audience of active finance professionals. Front page positioning induces 280% higher trading volume...

Video production involves the process of capturing, editing, and composing video segments for delivery to a consumer. A composition must yield a coherent presentation of an event or narrative. This process can be automated if appropriate domain-specific metadata are associated with video segments and composition techniques are established. Automation leads to the support of dynamic composition ...

Despite the uncertainties associated with forecasts of the possible negative effects of climate change on natural environments, such research is often widely reported in the news media. Here we review the presentation in the UK news media and on the internet of an academic study published in Nature, forecasting future global extinctions as a result of climate change. The results and conclusions...

The snippets that web search engines generate for their result presentation are extracted from the retrieved web pages, reusing pieces of text that match a user’s query. Copyright owners of the retrieved web pages are typically not asked for usage rights. This long-time practice now faces increasing backlash from news publishers, legal action, and even new legislation in Germany and Spain: the ...

Recommender systems find relevant content for us online, including the personalized news we increasingly receive on Twitter and Facebook. As a consequence of personalization, we increasingly see content that agrees with our views, we cease to be exposed to views contrary to our own. Both algorithms and the users themselves filter content, and this creates more polarized points of view, so calle...
