News recommender systems – Survey and roads ahead     

Mozhgan Karimi  Dietmar Jannach  Michael Jugovac 《Information processing & management》2018,54(6):1203-1227

More and more people read the news online, e.g., by visiting the websites of their favorite newspapers or by navigating the sites of news aggregators. However, the abundance of news information that is published online every day through different channels can make it challenging for readers to locate the content they are interested in. The goal of News Recommender Systems (NRS) is to make reading suggestions to users in a personalized way. Due to their practical relevance, a variety of technical approaches to build such systems have been proposed over the last two decades. In this work, we review the state-of-the-art of designing and evaluating news recommender systems over the last ten years. One main goal of the work is to analyze which particular challenges of news recommendation (e.g., short item life times and recency aspects) have been well explored and which areas still require more work. Furthermore, in contrast to previous surveys, the paper specifically discusses methodological questions and today’s academic practice of evaluating and comparing different algorithmic news recommendation approaches based on accuracy measures.  相似文献

Global Newsworthiness and Reversed Domestication     

Erga Atad 《Journalism Practice》2017,11(6):760-776

This study examines whether news broadcasts across nations are more cosmopolitan or parochial in their essence. To answer this question, the article proposes two unique theoretical concepts: “global newsworthiness” and “reversed domestication.” Global newsworthiness refers to news broadcasts that include ranges of countries, selected by several different reporting criteria. Reversed domestication refers to the connection made between the country of origin of the broadcasting media and the news content. Four television news networks were compared—CNN International, BBC World News, Al Jazeera English and France 24. The findings point to different levels of global newsworthiness and reversed domestication.  相似文献   

Political Discussion,Political News,and Internet Use: Factors of Media Trust in South Korea     

Hyunjung Kim  Yoon-jung Choi 《Communication Research Reports》2017,34(3):211-220

This study examines political and communicative factors predicting trust in mainstream newspapers and television by analyzing a set of survey data collected in South Korea. The results show that supporters of the opposition party are less likely to trust the mainstream news media than supporters of the ruling party. Daily Internet use negatively predicted trust in media only for nonpartisans. However, for supporters of the opposition party, daily Internet use moderated the interaction effect between political discussion and exposure to political news on trust in media.  相似文献   

How user comments affect news processing and reality perception: Activation and refutation of regional prejudice     

Eun-Ju Lee  Hyun Suk Kim  Jaeho Cho 《Communication monographs》2017,84(1):75-93

An experiment (N?=?177) examined how user-generated comments on a crime news article, which attribute the reported crime to the local residents’ predispositions, affect individuals’ processing of the news and their reality perception. Participants who viewed the regionalism-invoking comments estimated the crime rates of the featured region to be higher than those exposed to regionalism-irrelevant or regionalism-counterbalancing comments, and such effects were more pronounced for those with a stronger regional self-identity. Moreover, those who read regionalism-related comments, either regionalism-invoking or regionalism-counterbalancing, (a) recalled better the locations featured in the focal and the subsequent, yet unrelated, news articles and (b) attributed greater responsibility to news media coverage for the persistence of regionalism, as compared to those who viewed regionalism-irrelevant comments.  相似文献

The Interaction of Issue and Image Frames on Political Candidate Assessment     

Sean Luechtefeld  Adam S. Richards 《Communication Studies》2016,67(1):20-36

This study examined the combined effect of character and policy coverage about a political candidate in news media on voters’ evaluations and thoughts about the candidate. A 2 (issue coverage: present/absent) × 2 (image coverage: present/absent) between-subject factorial experiment was conducted whereby participants (N = 134) read a version of an editorial article that varied in the coverage of a candidate’s character and policy positions. Results indicated that issue and image coverage, each in isolation, enhanced perceptions of the candidate’s image strength and issue strength. However, issue and image coverage when presented in combination compared to in isolation did not enhance perceptions of the candidate and in some cases hindered perceptions of candidate strength. When both coverage types were present, issue coverage dominated image coverage when participants formed image evaluations, whereas image coverage dominated issue coverage when they formed issue evaluations. Similar findings resulted for issue- and image-relevant thoughts. Implications about the effects of multicoverage political messages are discussed.  相似文献   

Visual Framing,Stigmatization, Race,and Obesity: Examining Television News Presentation of Stories about Obesity and Stories about Health     

Kira Varava 《Communication Studies》2016,67(5):509-529

This study conducted a content analysis to examine how weight and race/ethnicity impacted how people were portrayed in the imagery accompanying broadcast and cable television news stories about obesity compared to stories about health. Five hundred and seven people were analyzed in 135 stories. Results showed that people who were overweight were often shown as an isolated body part, but their portrayal was not entirely stigmatizing. Overweight people were often shown exercising, which combats weight stereotypes. Additionally, race/ethnicity did not make the portrayal more stigmatizing. The results of the content analysis are discussed with an emphasis on the larger implications of the findings.  相似文献
